+
+ Smarty/PHP errors
+
+ Smarty can catch many errors such as missing tag attributes
+ or malformed variable names. If this happens, you will see an error
+ similar to the following:
+
+
+ Smarty errors
+
+
+
+
+
+ Smarty shows you the template name, the line number and the error.
+ After that, the error consists of the actual line number in the Smarty
+ class that the error occured.
+
+
+
+ There are certain errors that Smarty cannot catch, such as missing
+ close tags. These types of errors usually end up in PHP compile-time
+ parsing errors.
+
+
+
+ PHP parsing errors
+
+
+
+
+
+
+ When you encounter a PHP parsing error, the error line number will
+ correspond to the compiled PHP script, not the template itself. Usually
+ you can look at the template and spot the syntax error. Here are some
+ common things to look for: missing close tags for {if}{/if} or
+ {section}{/section}, or syntax of logic within an {if} tag. If you
+ can't find the error, you might have to open the compiled PHP file and
+ go to the line number to figure out where the corresponding error is in
+ the template.
+
+
+
+
+ Tips & Tricks
+
+
+
+ Blank Variable Handling
+
+ There may be times when you want to print a default value for an empty
+ variable instead of printing nothing, such as printing " " so that
+ table backgrounds work properly. Many would use an {if} statement to
+ handle this, but there is a shorthand way with Smarty, using the
+ default variable modifier.
+
+
+ Printing when a variable is empty
+
+
+
+
+
+
+
+ Default Variable Handling
+
+ If a variable is used frequently throughout your templates, applying
+ the default modifier every time it is mentioned can get a bit ugly. You
+ can remedy this by assigning the variable its default value with the
+ assign function.
+
+
+ Assigning a template variable its default value
+
+
+
+
+
+
+ Passing variable title to header template
+
+ When the majority of your templates use the same headers and footers, it
+ is common to split those out into their own templates and include them.
+ But what if the header needs to have a different title, depending on
+ what page you are coming from? You can pass the title to the header when
+ it is included.
+
+
+ Passing the title variable to the header template
+
+
+
+
+
+ When the main page is drawn, the title of "Main Page" is passed to the
+ header.tpl, and will subsequently be used as the title. When the
+ archives page is drawn, the title will be "Archives". Notice in the
+ archive example, we are using a variable from the archives_page.conf
+ file instead of a hard coded variable. Also notice that "BC News" is
+ printed if the $title variable is not set, using the
+ default variable modifier.
+
+
+
+ Dates
+
+ As a rule of thumb, always pass dates to Smarty as timestamps. This
+ allows template designers to use date_format for full
+ control over date formatting, and also makes it easy to compare dates if
+ necessary.
+
+
+ NOTE: As of Smarty 1.4.0, you can pass dates to Smarty as unix
+ timestamps, mysql timestamps, or any date parsable by strtotime().
+
+
+ using date_format
+
+
+
+
+
+ When using {html_select_date} in a template, The programmer will most
+ likely want to convert the output from the form back into timestamp
+ format. Here is a function to help you with that.
+
+
+ converting form date elements back to a timestamp
+
+
+
+
+
+
+ WAP/WML
+
+ WAP/WML templates require a php Content-Type header to be passed along
+ with the template. The easist way to do this would be to write a custom
+ function that prints the header. If you are using caching, that won't
+ work so we'll do it using the insert tag (remember insert tags are not
+ cached!) Be sure that there is nothing output to the browser before the
+ template, or else the header may fail.

+

+
+
+ your Smarty template must begin with the insert tag :
+
+
+
+
+
+
+
+ Componentized Templates
+
+ Traditionally, programming templates into your applications goes as
+ follows: First, you accumulate your variables within your PHP
+ application, (maybe with database queries.) Then, you instantiate your
+ Smarty object, assign the variables and display the template. So lets
+ say for example we have a stock ticker on our template. We would
+ collect the stock data in our application, then assign these variables
+ in the template and display it. Now wouldn't it be nice if you could
+ add this stock ticker to any application by merely including the
+ template, and not worry about fetching the data up front?
+
+
+ You can do this by writing a custom plugin for fetching the content and
+ assigning it to a template variable.
+
+
+ componentized template
+
+assign($params['assign'],$ticker_info);

+
+
+ Obfuscating E-mail Addresses
+
+ Do you ever wonder how your E-mail address gets on so many spam mailing
+ lists? One way spammers collect E-mail addresses is from web pages. To
+ help combat this problem, you can make your E-mail address show up in
+ scrambled javascript in the HTML source, yet it it will look and work
+ correctly in the browser. This is done with the mailto plugin.
+
+
+ Example of Obfuscating an E-mail Address
+
+
+
+
+
+ Technical Note
+
+ This method isn't 100% foolproof. A spammer could conceivably program his
+ e-mail collector to decode these values, but not likely.

+
+ Smarty For Template Designers
+
+
+ Basic Syntax
+
+ All Smarty template tags are enclosed within delimiters. By
+ default, these delimiters are { and
+ }, but they can be changed.
+
+
+ For these examples, we will assume that you are using the default
+ delimiters. In Smarty, all content outside of delimiters is displayed as
+ static content, or unchanged. When Smarty encounters template tags, it
+ attempts to interpret them, and displays the appropriate output in their
+ place.
+
+
+
+ Comments
+
+ Template comments are surrounded by asterisks, and that is surrounded
+ by the delimiter tags like so: {* this is a comment *}
+ Smarty comments are not displayed in the final output of the template.
+ They are used for making internal notes in the templates.
+
+
+ Comments
+
+{* Smarty *}
+
+{* include the header file here *}
+{include file="header.tpl"}
+
+{include file=$includeFile}
+
+{include file=#includeFile#}
+
+{* display dropdown lists *}
+<SELECT name=company>
+{html_options values=$vals selected=$selected output=$output}
+</SELECT>
+
+
+
+
+ Functions
+
+ Each Smarty tag either prints a
+ variable or invokes some sort
+ of function. Functions are processed and displayed by enclosing the
+ function and its attributes into delimiters like so: {funcname
+ attr1="val" attr2="val"}.
+
+
+ function syntax
+
+{config_load file="colors.conf"}
+
+{include file="header.tpl"}
+
+{if $highlight_name}
+ Welcome, <font color="{#fontColor#}">{$name}!</font>
+{else}
+ Welcome, {$name}!
+{/if}
+
+{include file="footer.tpl"}
+
+
+ Both built-in functions and custom functions have the same syntax in
+ the templates. Built-in functions are the inner workings of Smarty,
+ such as if, section and
+ strip. They cannot be modified. Custom functions are
+ additional functions implemented via plugins. They can be modified to
+ your liking, or you can add new ones. html_options and
+ html_select_date are examples of custom functions.
+
+
+
+
+ Attributes
+
+ Most of the functions take attributes that specify or modify
+ their behavior. Attributes to Smarty functions are much like HTML
+ attributes. Static values don't have to be enclosed in quotes, but it
+ is recommended for literal strings. Variables may also be used, and
+ should not be in quotes.
+
+
+ Some attributes require boolean values (true or false). These can be
+ specified as either unquoted true,
+ on, and yes, or
+ false, off, and
+ no.
+
+
+ function attribute syntax
+
+{include file="header.tpl"}
+
+{include file=$includeFile}
+
+{include file=#includeFile#}
+
+{html_select_date display_days=yes}
+
+<SELECT name=company>
+{html_options values=$vals selected=$selected output=$output}
+</SELECT>
+
+
+
+ Embedding Vars in Double Quotes
+
+ Smarty will recognize assigned variables embedded in double quotes so long
+ as the variables contain only numbers, letters, underscores and brackets
+ []. With any other characters (period, object reference, etc.) the variable
+ must be surrounded by backticks.
+
+
+ embedded quotes syntax
+
+SYNTAX EXAMPLES:
+{func var="test $foo test"} <-- sees $foo
+{func var="test $foo_bar test"} <-- sees $foo_bar
+{func var="test $foo[0] test"} <-- sees $foo[0]
+{func var="test $foo[bar] test"} <-- sees $foo[bar]
+{func var="test $foo.bar test"} <-- sees $foo (not $foo.bar)
+{func var="test `$foo.bar` test"} <-- sees $foo.bar
+
+PRACTICAL EXAMPLES:
+{include file="subdir/$tpl_name.tpl"} <-- will replace $tpl_name with value
+{cycle values="one,two,`$smarty.config.myval`"} <-- must have backticks
+
+
+
+ Math
+
+ Math can be applied directly to variable values.
+
+
+ math examples
+
+{$foo+1}
+
+{$foo*$bar}
+
+{* some more complicated examples *}
+
+{$foo->bar-$bar[1]*$baz->foo->bar()-3*7}
+
+{if ($foo+$bar.test%$baz*134232+10+$b+10)}
+
+{$foo|truncate:"`$fooTruncCount/$barTruncFactor-1`"}
+
+{assign var="foo" value="`$foo+$bar`"}
+
+
+
+
+ Escaping Smarty Parsing
+
+ It is sometimes desirable or even necessary to have Smarty ignore sections it
+ would otherwise parse. A classic example is embedding Javascript or CSS code in
+ a template. The problem arises as those languages use the { and } characters
+ which are also the default delimiters for Smarty.
+
+
+
+ The simplest thing is to avoid the situation altogether by separating your Javascript
+ and CSS code into their own files and then using standard HTML methods to access them.
+
+
+ Including literal content is possible using {literal} .. {/literal} blocks.
+ Similar to HTML entity usage, you can use {ldelim} and {rdelim}
+ to display the current delimiters.
+
+
+
+ It is often convenient to simply change Smarty's $left_delimiter and
+ $right_delimiter.
+
+
+ changing delimiters example
+
+
+$smarty = new Smarty;
+$smarty->left_delimiter = '<!--{';
+$smarty->right_delimiter = '}-->';
+$smarty->assign('foo', 'bar');
+$smarty->display('example.tpl');
+
+--- example.tpl
+<script language="javascript">
+var foo = <!--{$foo}-->;
+function dosomething() {
+ alert("foo is " + foo);
+}
+dosomething();
+</script>
+
+
+
+
+
+
+
+
+ Variables
+
+ Smarty has several different types of variables. The type of the variable
+ depends on what symbol it is prefixed with (or enclosed within).
+
+
+
+ Variables in Smarty can be either displayed directly or used as arguments
+ for function attributes and modifiers, inside conditional expressions,
+ etc. To print a variable, simply enclose it in the delimiters so that it
+ is the only thing contained between them. Examples:
+
+{$Name}
+
+{$Contacts[row].Phone}
+
+<body bgcolor="{#bgcolor#}">
+
+
+
+ Variables assigned from PHP
+
+ Variables that are assigned from PHP are referenced by preceding them with
+ a dollar sign $. Variables assigned from within the
+ template with the assign
+ function are also displayed this way.
+
+
+
+ assigned variables
+
+Hello {$firstname}, glad to see you could make it.
+<p>
+Your last login was on {$lastLoginDate}.
+
+OUTPUT:
+
+Hello Doug, glad to see you could make it.
+<p>
+Your last login was on January 11th, 2001.
+
+
+
+ Associative arrays
+
+ You can also reference associative array variables that are
+ assigned from PHP by specifying the key after the '.' (period)
+ symbol.
+
+
+accessing associative array variables
+
+index.php:
+
+$smarty = new Smarty;
+$smarty->assign('Contacts',
+ array('fax' => '555-222-9876',
+ 'email' => 'zaphod@slartibartfast.com',
+ 'phone' => array('home' => '555-444-3333',
+ 'cell' => '555-111-1234')));
+$smarty->display('index.tpl');
+
+index.tpl:
+
+{$Contacts.fax}<br>
+{$Contacts.email}<br>
+{* you can print arrays of arrays as well *}
+{$Contacts.phone.home}<br>
+{$Contacts.phone.cell}<br>
+
+OUTPUT:
+
+555-222-9876<br>
+zaphod@slartibartfast.com<br>
+555-444-3333<br>
+555-111-1234<br>
+
+
+
+ Array indexes
+
+ You can reference arrays by their index, much like native PHP
+ syntax.
+
+
+accessing arrays by index
+
+index.php:
+
+$smarty = new Smarty;
+$smarty->assign('Contacts',
+ array('555-222-9876',
+ 'zaphod@slartibartfast.com',
+ array('555-444-3333',
+ '555-111-1234')));
+$smarty->display('index.tpl');
+
+index.tpl:
+
+{$Contacts[0]}<br>
+{$Contacts[1]}<br>
+{* you can print arrays of arrays as well *}
+{$Contacts[2][0]}<br>
+{$Contacts[2][1]}<br>
+
+OUTPUT:
+
+555-222-9876<br>
+zaphod@slartibartfast.com<br>
+555-444-3333<br>
+555-111-1234<br>
+
+
+
+ Objects
+
+ Properties of objects assigned from PHP can be referenced
+ by specifying the property name after the '->' symbol.
+
+
+accessing object properties
+
+name: {$person->name}<br>
+email: {$person->email}<br>
+
+OUTPUT:
+
+name: Zaphod Beeblebrox<br>
+email: zaphod@slartibartfast.com<br>
+
+
+
+
+
+ Variables loaded from config files
+
+ Variables that are loaded from the config files are referenced by
+ enclosing them within hash marks (#), or with the smarty variable
+ $smarty.config.
+ The second syntax is useful for embedding into quoted attribute
+ values.
+
+
+
+config variables
+
+foo.conf:
+
+pageTitle = "This is mine"
+bodyBgColor = "#eeeeee"
+tableBorderSize = "3"
+tableBgColor = "#bbbbbb"
+rowBgColor = "#cccccc"
+
+index.tpl:
+
+{config_load file="foo.conf"}
+<html>
+<title>{#pageTitle#}</title>
+<body bgcolor="{#bodyBgColor#}">
+<table border="{#tableBorderSize#}" bgcolor="{#tableBgColor#}">
+<tr bgcolor="{#rowBgColor#}">
+ <td>First</td>
+ <td>Last</td>
+ <td>Address</td>
+</tr>
+</table>
+</body>
+</html>
+
+index.tpl: (alternate syntax)
+
+{config_load file="foo.conf"}
+<html>
+<title>{$smarty.config.pageTitle}</title>
+<body bgcolor="{$smarty.config.bodyBgColor}">
+<table border="{$smarty.config.tableBorderSize}" bgcolor="{$smarty.config.tableBgColor}">
+<tr bgcolor="{$smarty.config.rowBgColor}">
+ <td>First</td>
+ <td>Last</td>
+ <td>Address</td>
+</tr>
+</table>
+</body>
+</html>
+
+
+OUTPUT: (same for both examples)
+
+<html>
+<title>This is mine</title>
+<body bgcolor="#eeeeee">
+<table border="3" bgcolor="#bbbbbb">
+<tr bgcolor="#cccccc">
+ <td>First</td>
+ <td>Last</td>
+ <td>Address</td>
+</tr>
+</table>
+</body>
+</html>
+
+
+ Config file variables cannot be used until
+ after they are loaded in from a config file. This procedure is
+ explained later in this document under
+ config_load.
+
+
+
+
+ {$smarty} reserved variable
+
+ The reserved {$smarty} variable can be used to access several
+ special template variables. The full list of them follows.
+
+
+
+ Request variables
+
+ The request variables such as get, post, cookies, server,
+ environment, and session variables can be accessed as demonstrated
+ in the examples below:
+
+
+
+ displaying request variables
+
+{* display value of page from URL (GET) http://www.domain.com/index.php?page=foo *}
+{$smarty.get.page}
+
+{* display the variable "page" from a form (POST) *}
+{$smarty.post.page}
+
+{* display the value of the cookie "username" *}
+{$smarty.cookies.username}
+
+{* display the server variable "SERVER_NAME" *}
+{$smarty.server.SERVER_NAME}
+
+{* display the system environment variable "PATH" *}
+{$smarty.env.PATH}
+
+{* display the php session variable "id" *}
+{$smarty.session.id}
+
+{* display the variable "username" from merged get/post/cookies/server/env *}
+{$smarty.request.username}
+
+
+ Note: For historical reasons {$SCRIPT_NAME} can be accessed
+ directly though {$smarty.server.SCRIPT_NAME} is the
+ proposed way to access this value.
+
+
+
+
+
+ {$smarty.now}
+
+ The current timestamp can be accessed with {$smarty.now}. The
+ number reflects the number of seconds passed since the so-called
+ Epoch (January 1, 1970) and can be passed directly to
+ date_format modifier for display purposes.
+
+
+
+using {$smarty.now}
+
+{* use the date_format modifier to show current date and time *}
+{$smarty.now|date_format:"%Y-%m-%d %H:%M:%S"}
+
+
+
+ {$smarty.const}
+
+ You can access PHP constant values directly.
+
+
+
+using {$smarty.const}
+
+{$smarty.const._MY_CONST_VAL}
+
+
+
+
+ {$smarty.capture}
+
+ The output captured via {capture}..{/capture} construct can be
+ accessed using {$smarty} variable. See section on
+ capture for an example.
+
+
+
+
+ {$smarty.config}
+
+ {$smarty} variable can be used to refer to loaded config variables.
+ {$smarty.config.foo} is a synonym for {#foo#}. See the section on
+ config_load for an example.
+
+
+
+
+ {$smarty.section}, {$smarty.foreach}
+
+ {$smarty} variable can be used to refer to 'section' and
+ 'foreach' loop properties. See docs for
+ section and
+ foreach.
+
+
+
+
+ {$smarty.template}
+
+ This variable contains the name of the current template being
+ processed.
+
+
+
+ {$smarty.version}
+
+ This variable contains the version of Smarty the template was compiled with.
+
+
+
+
+
+
+
+ Variable Modifiers
+
+ Variable modifiers can be applied to variables, custom functions or strings. To
+ apply a modifier, specify the value followed by the |
+ (pipe) and the modifier name. A modifier may accept additional parameters
+ that affect its behavior. These parameters follow the modifer name and are
+ separated by : (colon).
+
+
+ modifier example
+
+{* Uppercase the title *}
+<h2>{$title|upper}</h2>
+
+{* Truncate the topic to 40 characters use ... at the end *}
+Topic: {$topic|truncate:40:"..."}
+
+{* format a literal string *}
+{"now"|date_format:"%Y/%m/%d"}
+
+{* apply modifier to a custom function *}
+{mailto|upper address="me@domain.dom"}
+
+
+ If you apply a modifier to an array variable instead of a single value variable,
+ the modifier will be applied to every value in that array. If you really want
+ the modifier to work on an entire array as a value, you must prepend the
+ modifier name with an @ symbol like so:
+ {$articleTitle|@count} (this will print out the number of
+ elements in the $articleTitle array.)
+
+
+ Modifiers can be autoloaded from your $plugins_dir (also see:
+ Naming
+ Conventions) or can be registered explicitely (see: register_modifier). Additionally
+ all php-functions can be used as modifiers implicitly. (The
+ @count-example above actually uses php's
+ count-function and not a smarty-modifier). Using php-functions
+ as modifiers has two little pitfalls: First: Sometimes the order
+ of the function-parameters is not the desirable one
+ ({"%2.f"|sprintf:$float} actually works, but
+ asks for the more intuitive {For example:
+ $float|string_format:"%2.f"} that is provided by the
+ Smarty distribution). Second: with $security turned on all
+ php-functions that are to be used as modifiers have to be
+ declared trusted in the
+ $security_settings['MODIFIER_FUNCS']-array.
+
+
+
+ capitalize
+
+ This is used to capitalize the first letter of all words in a variable.
+
+
+ capitalize
+
+index.php:
+
+$smarty = new Smarty;
+$smarty->assign('articleTitle', 'Police begin campaign to rundown jaywalkers.');
+$smarty->display('index.tpl');
+
+index.tpl:
+
+{$articleTitle}

+ Built-in Functions
+
+ Smarty comes with several built-in functions. Built-in functions
+ are integral to the template language. You cannot create custom
+ functions with the same names, nor can you modify built-in functions.
+
+
+ capture
+
+
+
+
+
+
+
+
+
+ Attribute Name
+ Type
+ Required
+ Default
+ Description
+
+
+
+
+ name
+ string
+ no
+ default
+ The name of the captured block
+
+
+ assign
+ string
+ No
+ n/a
+ The variable name where to assign the captured output to
+
+
+
+
+
+ capture is used to collect the output of the template into a
+ variable instead of displaying it. Any content between {capture
+ name="foo"} and {/capture} is collected into the variable specified
+ in the name attribute. The captured content can be used in the
+ template from the special variable $smarty.capture.foo where foo is
+ the value passed in the name attribute. If you do not supply a name
+ attribute, then "default" will be used. All {capture} commands must
+ be paired with {/capture}. You can nest capture commands.
+
+
+ Technical Note
+
+ Smarty 1.4.0 - 1.4.4 placed the captured content into the
+ variable named $return. As of 1.4.5, this behavior was changed to use
+ the name attribute, so update your templates accordingly.
+
+
+
+
+ Be careful when capturing insert output. If
+ you have caching turned on and you have insert
+ commands that you expect to run within cached content, do not
+ capture this content.

+
+ global
+ boolean
+ No
+ No
+
+ Whether or not variables are visible to the parent
+ template, same as scope=parent. NOTE: This attribute is
+ deprecated by the scope attribute, but still supported.
+ If scope is supplied, this value is ignored.
+
+
+
+
+
+
+ This function is used for loading in variables from a
+ configuration file into the template.
+ See Config Files for more
+ info.

+ The name of the foreach loop for accessing
+ foreach properties
+
+
+
+
+
+ foreach loops are an alternative to
+ section loops. foreach is
+ used to loop over a single associative array. The syntax for
+ foreach is much easier than
+ section, but as a tradeoff it can only be used
+ for a single array. foreach tags must be
+ paired with /foreach tags. Required parameters
+ are from and item. The
+ name of the foreach loop can be anything you like, made up of
+ letters, numbers and underscores. foreach
+ loops can be nested, and the nested foreach names must be unique
+ from each other. The from variable (usually an
+ array of values) determines the number of times
+ foreach will loop.
+ foreachelse is executed when there are no
+ values in the from variable.
+
+
+foreach
+
+
+{* this example will print out all the values of the $custid array *}
+{foreach from=$custid item=curr_id}
+ id: {$curr_id}<br>
+{/foreach}
+
+OUTPUT:
+
+id: 1000<br>
+id: 1001<br>
+id: 1002<br>
+
+
+

+
+{* The key contains the key for each looped value
+

+
+$smarty->assign("contacts", array(array("phone" => "1", "fax" => "2", "cell" => "3"),
+ array("phone" => "555-4444", "fax" => "555-3333", "cell" => "760-1234")));
+
+*}
+
+{foreach name=outer item=contact from=$contacts}
+ {foreach key=key item=item from=$contact}
+ {$key}: {$item}<br>

+fax: 555-3333<br>
+cell: 760-1234<br>
+
+
+
+ Foreach-loops also have their own variables that handle foreach properties.
+ These are indicated like so: {$smarty.foreach.foreachname.varname} with
+ foreachname being the name specified as the name
+ attribute of foreach
+
+
+
+
+ iteration
+
+ iteration is used to display the current loop iteration.
+
+
+ Iteration always starts with 1 and is incremented by one
+ one each iteration.
+
+
+
+
+ first
+
+ first is set to true if the current foreach iteration is the first
+ one.
+
+
+

+
+ last is set to true if the current foreach iteration is the last

+
+
+
+
+ show
+
+ show is used as a parameter to foreach.
+ show is a boolean value, true or false. If
+ false, the foreach will not be displayed. If there is a foreachelse
+ present, that will be alternately displayed.
+
+
+
+
+ total
+
+ total is used to display the number of iterations that this foreach
+ will loop. This can be used inside or after the foreach.

+
+
+ Include tags are used for including other templates in the current

+ available within the included template. The include tag must have
+ the attribute "file", which contains the template resource path.
+
+
+ You can optionally pass the assign attribute,

+ displayed.
+
+
+function include

+{include file="header.tpl"}
+
+{* body of template goes here *}
+
+{include file="footer.tpl"}
+
+
+ You can also pass variables to included templates as attributes.
+ Any variables explicitly passed to an included template as

+
+ assign
+ string
+ No
+ n/a
+ The name of the variable that the output of
+ include_php will be assigned to
+
+
+
+
+
+ Technical Note
+
+ include_php is pretty much deprecated from Smarty, you can
+ accomplish the same functionality via a custom template function.
+ The only reason to use include_php is if you really have a need to
+ quarantine the php function away from the plugin directory or your
+ application code. See the componentized template
+ example for details.
+
+
+
+ include_php tags are used to include a php script in your template.
+ If security is enabled, then the php script must be located in the
+ $trusted_dir path. The include_php tag must have the attribute
+ "file", which contains the path to the included php file, either
+ relative to $trusted_dir, or an absolute path.
+
+
+ include_php is a nice way to handle componentized templates, and
+ keep PHP code separate from the template files. Lets say you have a
+ template that shows your site navigation, which is pulled
+ dynamically from a database. You can keep your PHP logic that grabs
+ database content in a separate directory, and include it at the top
+ of the template. Now you can include this template anywhere without
+ worrying if the database information was assigned by the application
+ before hand.
+
+
+ By default, php files are only included once even if called
+ multiple times in the template. You can specify that it should be
+ included every time with the once attribute.
+ Setting once to false will include the php script each time it is
+ included in the template.
+
+
+ You can optionally pass the assign attribute,
+ which will specify a template variable name that the output of
+ include_php will be assigned to instead of
+ displayed.
+
+
+ The smarty object is available as $this within the PHP script that you
+ include.

+ n/a
+ variable to pass to insert function
+
+
+
+
+
+ Insert tags work much like include tags, except that insert tags
+ are not cached when you have template caching enabled. They will be
+ executed on every invocation of the template.
+
+
+ Let's say you have a template with a banner slot at the top of
+ the page. The banner can contain any mixture of HTML, images,
+ flash, etc. so we can't just use a static link here, and we
+ don't want this contents cached with the page. In comes the
+ insert tag: the template knows #banner_location_id# and
+ #site_id# values (gathered from a config file), and needs to
+ call a function to get the banner contents.
+
+
+function insert
+
+{* example of fetching a banner *}
+{insert name="getBanner" lid=#banner_location_id# sid=#site_id#}
+
+
+ In this example, we are using the name "getBanner" and passing the
+ parameters #banner_location_id# and #site_id#. Smarty will look
+ for a function named insert_getBanner() in your PHP application, passing
+ the values of #banner_location_id# and #site_id# as the first argument
+ in an associative array. All insert function names in
+ your application must be prepended with "insert_" to remedy possible
+ function name-space conflicts. Your insert_getBanner() function should
+ do something with the passed values and return the results. These results
+ are then displayed in the template in place of the insert tag.
+ In this example, Smarty would call this function:
+ insert_getBanner(array("lid" => "12345","sid" => "67890"));
+ and display the returned results in place of the insert tag.
+
+
+ If you supply the "assign" attribute, the output of the insert tag
+ will be assigned to this template variable instead of being output
+ to the template. NOTE: assigning the output to a template variable
+ isn't too useful with caching enabled.
+
+
+ If you supply the "script" attribute, this php script will be
+ included (only once) before the insert function is executed. This
+ is the case where the insert function may not exist yet, and a php
+ script must be included first to make it work. The path can be
+ either absolute, or relative to $trusted_dir. When security is
+ enabled, the script must reside in $trusted_dir.
+
+
+ The Smarty object is passed as the second argument. This way you
+ can reference and modify information in the Smarty object from
+ within the insert function.
+
+
+ Technical Note
+
+ It is possible to have portions of the template not
+ cached. If you have caching
+ turned on, insert tags will not be cached. They will run
+ dynamically every time the page is created, even within cached
+ pages. This works good for things like banners, polls, live
+ weather, search results, user feedback areas, etc.
+
+
+
+
+ if,elseif,else
+
+ {if} statements in Smarty have much the same flexibility as PHP if
+ statements, with a few added features for the template engine.
+ Every {if} must be paired with an
+ {/if}. {else} and
+ {elseif} are also permitted. All PHP conditionals
+ are recognized, such as ||, or,
+ &&, and, etc.
+
+
+
+ The following is a list of recognized qualifiers, which must be
+ separated from surrounding elements by spaces. Note that items listed
+ in [brackets] are optional. PHP equivalents are shown where applicable.

+
+ ldelim,rdelim
+
+ ldelim and rdelim are used for displaying the literal delimiter, in

+ delimiters, so this is the way around that.

+ldelim, rdelim
+
+{* this will print literal delimiters out of the template *}

+
+
+ literal
+
+ Literal tags allow a block of data to be taken literally,
+ not being interpreted by the Smarty engine. This is handy
+ for things like javascript sections, where there maybe
+ curly braces and such things that would confuse the template
+ parser. Anything within {literal}{/literal} tags is not
+ interpreted, but displayed as-is.

+
+
+
+
+ strip
+
+ Many times web designers run into the issue where white space and
+ carriage returns affect the output of the rendered HTML (browser
+ "features"), so you must run all your tags together in the template
+ to get the desired results. This usually ends up in unreadable or
+ unmanageable templates.
+
+
+ Anything within {strip}{/strip} tags in Smarty are stripped of the
+ extra spaces or carriage returns at the beginnings and ends of the
+ lines before they are displayed. This way you can keep your
+ templates readable, and not worry about extra white space causing
+ problems.
+
+
+ Technical Note
+
+ {strip}{/strip} does not affect the contents of template variables.
+ See the strip modifier
+ function.
+
+
+
+strip tags
+
+{* the following will be all run into one line upon output *}
+{strip}
+<table border=0>
+ <tr>
+ <td>
+ <A HREF="{$url}">
+ <font color="red">This is a test</font>
+ </A>
+ </td>
+ </tr>
+</table>
+{/strip}
+
+
+OUTPUT:
+
+<table border=0><tr><td><A HREF="http://my.domain.com"><font color="red">This is a test</font></A></td></tr></table>
+
+
+ Notice that in the above example, all the lines begin and end
+ with HTML tags. Be aware that all the lines are run together.
+ If you have plain text at the beginning or end of any line,
+ they will be run together, and may not be desired results.
+
+
+
+
+
+ Custom Functions
+
+ Smarty comes with several custom functions that you can
+ use in the templates.
+
+
+ assign
+
+
+
+
+
+
+
+
+
+ Attribute Name
+ Type
+ Required
+ Default
+ Description
+
+
+
+
+ var
+ string
+ Yes
+ n/a
+ The name of the variable being assigned
+
+
+ value
+ string
+ Yes
+ n/a
+ The value being assigned
+
+
+
+
+
+ assign is used for assigning template variables during the execution
+ of the template.
+
+
+assign
+
+{assign var="name" value="Bob"}
+
+The value of $name is {$name}.
+
+OUTPUT:
+
+The value of $name is Bob.
+
+
+
+ counter
+
+
+
+
+
+
+
+
+
+ Attribute Name
+ Type
+ Required
+ Default
+ Description
+
+
+
+
+ name
+ string
+ No
+ default
+ The name of the counter
+
+
+ start
+ number
+ No
+ 1
+ The initial number to start counting from
+
+
+ skip
+ number
+ No
+ 1
+ The interval to count by
+
+
+ direction
+ string
+ No
+ up
+ the direction to count (up/down)
+
+
+ print
+ boolean
+ No
+ true
+ Whether or not to print the value
+
+
+ assign
+ string
+ No
+ n/a
+ the template variable the output will be assigned
+ to
+
+
+
+
+
+ counter is used to print out a count. counter will remember the
+ count on each iteration. You can adjust the number, the interval
+ and the direction of the count, as well as determine whether or not
+ to print the value. You can run multiple counters concurrently by
+ supplying a unique name for each one. If you do not supply a name,
+ the name 'default' will be used.
+
+
+ If you supply the special "assign" attribute, the output of the
+ counter function will be assigned to this template variable instead of
+ being output to the template.
+
+
+counter
+
+{* initialize the count *}
+{counter start=0 skip=2}<br>
+{counter}<br>
+{counter}<br>
+{counter}<br>
+
+OUTPUT:
+
+0<br>

+
+
+
+ cycle
+
+
+
+
+
+
+
+
+
+ Attribute Name
+ Type
+ Required
+ Default
+ Description
+
+
+
+
+ name
+ string
+ No
+ default
+ The name of the cycle
+
+
+ values
+ mixed
+ Yes
+ N/A
+ The values to cycle through, either a comma
+ delimited list (see delimiter attribute), or an array
+ of values.
+
+
+ print
+ boolean
+ No
+ true
+ Whether to print the value or not
+
+
+ advance
+ boolean
+ No
+ true
+ Whether or not to advance to the next value
+
+
+ delimiter
+ string
+ No
+ ,
+ The delimiter to use in the values attribute.
+
+
+ assign
+ string
+ No
+ n/a
+ the template variable the output will be assigned
+ to
+
+
+
+
+
+ Cycle is used to cycle though a set of values. This makes it easy
+ to alternate between two or more colors in a table, or cycle
+ through an array of values.
+
+
+ You can cycle through more than one set of values in your template
+ by supplying a name attribute. Give each set of values a unique
+ name.
+
+
+ You can force the current value not to print with the print
+ attribute set to false. This would be useful for silently skipping
+ a value.
+
+
+ The advance attribute is used to repeat a value. When set to false,
+ the next call to cycle will print the same value.
+
+
+ If you supply the special "assign" attribute, the output of the
+ cycle function will be assigned to this template variable instead of
+ being output to the template.
+
+
+cycle
+
+{section name=rows loop=$data}
+<tr bgcolor="{cycle values="#eeeeee,#d0d0d0"}">
+ <td>{$data[rows]}</td>
+</tr>
+{/section}
+
+OUTPUT:
+
+<tr bgcolor="#eeeeee">
+ <td>1</td>
+</tr>
+<tr bgcolor="#d0d0d0">
+ <td>2</td>
+</tr>
+<tr bgcolor="#eeeeee">
+ <td>3</td>
+</tr>

+
+
+ debug
+

+ Description
+
+
+
+
+ output
+ string
+ No
+ html
+ output type, html or javascript
+
+
+
+
+
+ {debug} dumps the debug console to the page. This works regardless
+ of the debug
+ settings in Smarty. Since this gets executed at runtime, this is
+ only able to show the assigned variables, not the templates that
+ are in use. But, you see all the currently available variables
+ within the scope of this template.
+
+
+
+ eval
+
+
+
+
+
+
+
+
+
+ Attribute Name
+ Type
+ Required

+ n/a
+ variable (or string) to evaluate
+
+
+ assign
+ string
+ No
+ n/a
+ the template variable the output will be assigned
+ to
+
+
+
+
+
+ eval is used to evaluate a variable as a template. This can be used
+ for things like embedding template tags/variables into variables or
+ tags/variables into config file variables.
+
+
+ If you supply the special "assign" attribute, the output of the
+ eval function will be assigned to this template variable instead of
+ being output to the template.
+
+
+ Technical Note
+
+ Evaluated variables are treated the same as templates. They follow
+ the same escapement and security features just as if they were
+ templates.
+
+
+
+ Technical Note
+
+ Evaluated variables are compiled on every invocation, the compiled
+ versions are not saved! However if you have caching enabled, the
+ output will be cached with the rest of the template.
+
+
+

+
+
+
+ fetch is used to fetch files from the local file system, http, or
+ ftp and display the contents. If the file name begins with
+ "http://", the web site page will be fetched and displayed. If the
+ file name begins with "ftp://", the file will be fetched from the
+ ftp server and displayed. For local files, the full system file
+ path must be given, or a path relative to the executed php script.
+
+
+ If you supply the special "assign" attribute, the output of the
+ fetch function will be assigned to this template variable instead of
+ being output to the template. (new in Smarty 1.5.0)
+
+
+ Technical Note
+
+ This will not support http redirects, be sure to
+ include a trailing slash on your web page fetches where necessary.
+
+
+
+ Technical Note
+
+ If template security is turned on and you are
+ fetching a file from the local file system, this will only allow
+ files from within one of the defined secure directories.

+
+
+
+ html_image is a custom function that generates an HTML tag for an
+ image. The height and width are automatically calculated from the
+ image file if none are supplied.
+
+
+ basedir is the base directory that relative image paths are based
+ from. If not given, the web server document root (env variable
+ DOCUMENT_ROOT) is used as the base. If security is enabled, the
+ path to the image must be within a secure directory.
+
+
+ href is the href value to link the image to. If link is supplied, an
+ <a href="LINKVALUE"><a> tag is put around the image tag.
+
+
+ Technical Note
+
+ html_image requires a hit to the disk to read the image and
+ calculate the height and width. If you don't use template
+ caching, it is generally better to avoid html_image and leave
+ image tags static for optimal performance.

+ Yes

+ No

+ template variable the output will be assigned to
+
+
+ [var ...]
+ numeric
+ Yes
+ n/a
+ equation variable value
+
+
+
+
+
+ math allows the template designer to do math equations in the
+ template. Any numeric template variables may be used in the
+ equations, and the result is printed in place of the tag. The
+ variables used in the equation are passed as parameters, which can
+ be template variables or static values. +, -, /, *, abs, ceil, cos,
+ exp, floor, log, log10, max, min, pi, pow, rand, round, sin, sqrt,
+ srans and tan are all valid operators. Check the PHP documentation
+ for further information on these math functions.
+
+
+ If you supply the special "assign" attribute, the output of the
+ math function will be assigned to this template variable instead of
+ being output to the template.
+
+
+ Technical Note
+
+ math is an expensive function in performance due to its use of
+ the php eval() function. Doing the math in PHP is much more
+ efficient, so whenever possible do the math calculations in PHP
+ and assign the results to the template. Definately avoid
+ repetitive math function calls, like within section loops.

+
+ Config Files
+
+ Config files are handy for designers to manage global template
+ variables from one file. One example is template colors. Normally if
+ you wanted to change the color scheme of an application, you would have
+ to go through each and every template file and change the colors. With
+ a config file, the colors can be kept in one place, and only one file
+ needs to be updated.
+
+
+ Example of config file syntax
+
+# global variables
+pageTitle = "Main Menu"
+bodyBgColor = #000000
+tableBgColor = #000000
+rowBgColor = #00ff00
+
+[Customer]
+pageTitle = "Customer Info"
+
+[Login]
+pageTitle = "Login"
+focus = "username"
+Intro = """This is a value that spans more
+ than one line. you must enclose
+ it in triple quotes."""
+
+# hidden section
+[.Database]
+host=my.domain.com
+db=ADDRESSBOOK
+user=php-user
+pass=foobar
+
+
+ Values of config file variables can be in quotes, but not necessary.
+ You can use either single or double quotes. If you have a value that
+ spans more than one line, enclose the entire value with triple quotes
+ ("""). You can put comments into config files by any syntax that is not
+ a valid config file syntax. We recommend using a #
+ (hash) at the beginning of the line.
+
+
+ This config file example has two sections. Section names are enclosed in
+ brackets []. Section names can be arbitrary strings not containing
+ [ or ] symbols. The four variables
+ at the top are global variables, or variables not within a section.
+ These variables are always loaded from the config file. If a particular
+ section is loaded, then the global variables and the variables from that
+ section are also loaded. If a variable exists both as a global and in a
+ section, the section variable is used. If you name two variables the
+ same within a section, the last one will be used.
+
+
+ Config files are loaded into templates with the built-in function
+ config_load.
+
+
+ You can hide variables or entire sections by prepending the variable
+ name or section name with a period. This is useful if your application
+ reads the config files and gets sensitive data from them that the
+ template engine does not need. If you have third parties doing template
+ editing, you can be certain that they cannot read sensitive data from
+ the config file by loading it into the template.
+
+
+
+
+ Debugging Console
+
+ There is a debugging console included with Smarty. The console informs you
+ of all the included templates, assigned variables and config file variables
+ for the current invocation of the template. A template named "debug.tpl" is
+ included with the distribution of Smarty which controls the formatting of
+ the console. Set $debugging to true in Smarty, and if needed set $debug_tpl
+ to the template resource path for debug.tpl (this is in SMARTY_DIR by
+ default.) When you load the page, a javascript console window should pop up
+ and give you the names of all the included templates and assigned variables
+ for the current page. To see the available variables for a particular
+ templates, see the {debug}
+ template function. To disable the debugging console, set $debugging to
+ false. You can also temporarily turn on the debugging console by putting
+ SMARTY_DEBUG in the URL if you enable this option with $debugging_ctrl.
+
+
+ Technical Note
+
+ The debugging console does not work when you use the fetch()
+ API, only when using display(). It is a set of javascript statements added
+ to the very bottom of the generated template. If you do not like javascript,
+ you can edit the debug.tpl template to format the output however you like.
+ Debug data is not cached and debug.tpl info is not included in the output of
+ the debug console.
+
+
+
+
+ The load times of each template and config file are in seconds, or
+ fractions thereof.

+
+ Getting Started
+
+
+ What is Smarty?
+
+ Smarty is a template engine for PHP. More specifically, it facilitates a
+ manageable way to separate application logic and content from its
+ presentation. This is best described in a situation where the application
+ programmer and the template designer play different roles, or in most cases
+ are not the same person. For example, let's say you are creating a web page
+ that is displaying a newspaper article. The article headline, tagline,
+ author and body are content elements, they contain no information about how
+ they will be presented. They are passed into Smarty by the application,
+ then the template designer edits the templates and uses a combination of
+ HTML tags and template tags to format the presentation of these elements
+ (HTML tables, background colors, font sizes, style sheets, etc.) One day
+ the programmer needs to change the way the article content is retrieved (a
+ change in application logic.) This change does not affect the template
+ designer, the content will still arrive in the template exactly the same.
+ Likewise, if the template designer wants to completely redesign the
+ templates, this requires no changes to the application logic. Therefore,
+ the programmer can make changes to the application logic without the need
+ to restructure templates, and the template designer can make changes to
+ templates without breaking application logic.
+
+
+ One design goal of Smarty is the separation of business logic and
+ presentation logic. This means templates can certainly contain logic under
+ the condition that it is for presentation only. Things such as including
+ other templates, altering table row colors, upper-casing a variable,
+ looping over an array of data and displaying it, etc. are all examples of
+ presentation logic. This does not mean that Smarty forces a separation of
+ business and presentation logic. Smarty has no knowledge of which is which,
+ so placing business logic in the template is your own doing. Also, if you
+ desire NO logic in your templates you certainly can do so by boiling the
+ content down to text and variables only.
+
+
+ One of the unique aspects about Smarty is the template compling. This means
+ Smarty reads the template files and creates PHP scripts from them. Once
+ they are created, they are executed from then on. Therefore there is no
+ costly template file parsing for each request, and each template can take
+ full advantage of PHP compiler cache solutions such as Zend Accelerator
+ (http://www.zend.com) or PHP Accelerator
+ (http://www.php-accelerator.co.uk).
+
+
+ Some of Smarty's features:
+
+
+
+
+ It is extremely fast.
+
+
+
+
+ It is efficient since the PHP parser does the dirty work.
+
+
+
+
+ No template parsing overhead, only compiles once.
+
+
+
+
+ It is smart about recompiling only the template files that have changed.
+
+
+
+
+ You can make custom functions
+ and custom variable modifiers, so the
+ template language is extremely extensible.
+
+
+
+
+ Configurable template delimiter tag syntax, so you can use
+ {}, {{}}, <!--{}-->, etc.
+
+
+
+
+ The if/elseif/else/endif constructs are passed to the
+ PHP parser, so the {if ...} expression syntax can be as simple or as complex
+ as you like.
+
+
+
+
+ Unlimited nesting of sections, ifs, etc. allowed.
+
+
+
+
+ It is possible to embed PHP code right in your template files,
+ although this may not be needed (nor recommended)
+ since the engine is so customizable.
+
+
+
+
+ Built-in caching support
+
+
+
+
+ Arbitrary template sources
+
+
+
+
+ Custom cache handling functions
+
+
+
+
+ Plugin architecture
+
+
+
+
+
+ Installation
+
+
+ Requirements
+
+ Smarty requires a web server running PHP 4.0.6 or later.
+
+
+
+
+ Basic Installation
+
+ Install the Smarty library files which are in the /libs/ directory of
+ the distribution. These are the PHP files that you SHOULD NOT edit. They
+ are shared among all applications and they only get updated when you
+ upgrade to a new version of Smarty.
+
+
+ Smarty library files
+
+
+
+
+
+ Smarty uses a PHP constant named SMARTY_DIR which is the system
+ filepath Smarty library directory. Basically, if your application can find
+ the Smarty.class.php file, you do not need to set
+ SMARTY_DIR, Smarty will figure it out on its own. Therefore, if
+ Smarty.class.php is not in your include_path, or you
+ do not supply an absolute path to it in your application, then you must
+ define SMARTY_DIR manually. SMARTY_DIR must include a
+ trailing slash.
+
+
+ Here is how you create an instance of Smarty in your PHP scripts:
+
+
+
+ Create Smarty instance of Smarty
+
+
+]]>
+
+
+
+
+ Try running the above script. If you get an error saying the
+ Smarty.class.php file could not be found, you have to
+ do one of the following:
+
+
+
+ Supply absolute path to library file
+
+
+]]>
+
+
+
+
+ Add library directory to php_include path
+
+
+]]>
+
+
+
+
+ Set SMARTY_DIR constant manually
+
+
+]]>
+
+
+
+
+ Now that the library files are in place, it's time to setup the Smarty
+ directories for your application. Smarty requires four directories which
+ are (by default) named templates,
+ templates_c, configs and
+ cache. Each of these are definable by the Smarty class
+ properties $template_dir,
+ $compile_dir, $config_dir, and
+ $cache_dir respectively. It is highly recommended
+ that you setup a separate set of these directories for each application
+ that will use Smarty.
+
+
+ Be sure you know the location of your web server document root. In our
+ example, the document root is "/web/www.mydomain.com/docs/". The Smarty
+ directories are only accessed by the Smarty library and never accessed
+ directly by the web browser. Therefore to avoid any security concerns, it
+ is recommended to place these directories outside of
+ the document root.
+
+
+ For our installation example, we will be setting up the Smarty environment
+ for a guest book application. We picked an application only for the purpose
+ of a directory naming convention. You can use the same environment for any
+ application, just replace "guestbook" with the name of your app. We'll
+ place our Smarty directories under
+ "/web/www.mydomain.com/smarty/guestbook/".
+
+
+ You will need as least one file under your document root, and that is the
+ script accessed by the web browser. We will call our script "index.php",
+ and place it in a subdirectory under the document root called
+ "/guestbook/".
+
+
+
+ Technical Note
+
+ It is convenient to setup the web server so that "index.php" can be
+ identified as the default directory index, so if you access
+ "http://www.mydomain.com/guestbook/", the index.php script will be executed
+ without "index.php" in the URL. In Apache you can set this up by adding
+ "index.php" onto the end of your DirectoryIndex setting (separate each
+ entry with a space.)
+
+
+
+
+ Lets take a look at the file structure so far:
+
+
+
+ Example file structure
+
+
+
+
+
+
+ Smarty will need write access to the $compile_dir and
+ $cache_dir, so be sure the web server user can write
+ to them. This is usually user "nobody" and group "nobody". For OS X users,
+ the default is user "www" and group "www". If you are using Apache, you can
+ look in your httpd.conf file (usually in "/usr/local/apache/conf/") to see
+ what user and group are being used.
+
+
+
+ Setting file permissions
+
+
+
+
+
+
+ Technical Note
+
+ chmod 770 will be fairly tight security, it only allows user "nobody" and
+ group "nobody" read/write access to the directories. If you would like to
+ open up read access to anyone (mostly for your own convenience of viewing
+ these files), you can use 775 instead.
+
+
+
+
+ We need to create the index.tpl file that Smarty will load. This will be
+ located in your $template_dir.
+
+
+
+ Editing /web/www.mydomain.com/smarty/guestbook/templates/index.tpl
+
+
+
+
+
+
+ Technical Note
+
+ {* Smarty *} is a template comment. It is not required, but it is good
+ practice to start all your template files with this comment. It makes
+ the file easy to recognize regardless of the file extension. For
+ example, text editors could recognize the file and turn on special
+ syntax highlighting.
+
+
+
+
+ Now lets edit index.php. We'll create an instance of Smarty, assign a
+ template variable and display the index.tpl file. In our example
+ environment, "/usr/local/lib/php/Smarty" is in our include_path. Be sure you
+ do the same, or use absolute paths.
+
+
+
+ Editing /web/www.mydomain.com/docs/guestbook/index.php
+
+template_dir = '/web/www.mydomain.com/smarty/guestbook/templates/';
+$smarty->compile_dir = '/web/www.mydomain.com/smarty/guestbook/templates_c/';
+$smarty->config_dir = '/web/www.mydomain.com/smarty/guestbook/configs/';
+$smarty->cache_dir = '/web/www.mydomain.com/smarty/guestbook/cache/';
+
+$smarty->assign('name','Ned');
+
+$smarty->display('index.tpl');
+?>
+]]>
+
+
+
+
+ Technical Note
+
+ In our example, we are setting absolute paths to all of the Smarty
+ directories. If '/web/www.mydomain.com/smarty/guestbook/' is within your
+ PHP include_path, then these settings are not necessary. However, it is
+ more efficient and (from experience) less error-prone to set them to
+ absolute paths. This ensures that Smarty is getting files from the
+ directories you intended.
+
+
+
+
+ Now load the index.php file from your web browser. You should see "Hello,
+ Ned!"
+
+
+ You have completed the basic setup for Smarty!
+
+
+
+ Extended Setup
+
+
+ This is a continuation of the basic installation, please read
+ that first!
+
+
+ A slightly more flexible way to setup Smarty is to extend the class and
+ initialize your Smarty environment. So instead of repeatedly setting
+ directory paths, assigning the same vars, etc., we can do that in one place.
+ Lets create a new directory "/php/includes/guestbook/" and make a new file
+ called "setup.php". In our example environment, "/php/includes" is in our
+ include_path. Be sure you set this up too, or use absolute file paths.
+
+
+
+ Editing /php/includes/guestbook/setup.php
+
+Smarty();
+
+ $this->template_dir = '/web/www.mydomain.com/smarty/guestbook/templates/';
+ $this->compile_dir = '/web/www.mydomain.com/smarty/guestbook/templates_c/';
+ $this->config_dir = '/web/www.mydomain.com/smarty/guestbook/configs/';
+ $this->cache_dir = '/web/www.mydomain.com/smarty/guestbook/cache/';
+
+ $this->caching = true;
+ $this->assign('app_name','Guest Book');
+ }
+
+}
+?>
+]]>
+
+
+
+
+ Now lets alter the index.php file to use setup.php:
+
+
+
+ Editing /web/www.mydomain.com/docs/guestbook/index.php
+
+assign('name','Ned');
+
+$smarty->display('index.tpl');
+?>
+]]>
+
+
+
+
+ Now you see it is quite simple to bring up an instance of Smarty, just use
+ Smarty_GuestBook which automatically initializes everything for our application.

+
+ Preface
+
+ It is undoubtedly one of the most asked questions on the PHP mailing
+ lists: how do I make my PHP scripts independent of the layout? While
+ PHP is billed as "HTML embedded scripting language", after writing a
+ couple of projects that mixed PHP and HTML freely one comes up with the
+ idea that separation of form and content is a Good Thing [TM]. In
+ addition, in many companies the roles of layout designer and programmer
+ are separate. Consequently, the search for a templating solution
+ ensues.
+
+
+ In our company for example, the development of an application goes on
+ as follows: After the requirements docs are done, the interface
+ designer makes mockups of the interface and gives them to the
+ programmer. The programmer implements business logic in PHP and uses
+ interface mockups to create skeleton templates. The project is then
+ handed off to the HTML designer/web page layout person who brings the
+ templates up to their full glory. The project may go back and forth
+ between programming/HTML a couple of times. Thus, it's important to
+ have good template support because programmers don't want anything to
+ do with HTML and don't want HTML designers mucking around with PHP
+ code. Designers need support for config files, dynamic blocks and
+ other interface issues, but they don't want to have to deal with
+ intricacies of the PHP programming language.
+
+
+ Looking at many templating solutions available for PHP today, most of
+ them provide a rudimentary way of substituting variables into templates
+ and do a limited form of dynamic block functionality. But our needs
+ required a bit more than that. We didn't want programmers to be dealing
+ with HTML layout at ALL, but this was almost inevitable. For instance,
+ if a designer wanted background colors to alternate on dynamic blocks,
+ this had to be worked out with the programmer in advance. We also
+ needed designers to be able to use their own configuration files, and
+ pull variables from them into the templates. The list goes on.
+
+
+ We started out writing out a spec for a template engine back in late
+ 1999. After finishing the spec, we began to work on a template engine
+ written in C that would hopefully be accepted for inclusion with PHP.
+ Not only did we run into many complicated technical barriers, but there
+ was also much heated debate about exactly what a template engine should
+ and should not do. From this experience, we decided that the template
+ engine should be written in PHP as a class, for anyone to use as they
+ see fit. So we wrote an engine that did just that and
+ SmartTemplate came into existence (note: this
+ class was never submitted to the public). It was a class that did
+ almost everything we wanted: regular variable substitution, supported
+ including other templates, integration with config files, embedding PHP
+ code, limited 'if' statement functionality and much more robust dynamic
+ blocks which could be multiply nested. It did all this with regular
+ expressions and the code turned out to be rather, shall we say,
+ impenetrable. It was also noticably slow in large applications from all
+ the parsing and regular expression work it had to do on each
+ invocation. The biggest problem from a programmer's point of view was
+ all the necessary work in the PHP script to setup and process templates
+ and dynamic blocks. How do we make this easier?
+
+
+ Then came the vision of what ultimately became Smarty. We know how fast
+ PHP code is without the overhead of template parsing. We also know how
+ meticulous and overbearing the PHP language may look to the average
+ designer, and this could be masked with a much simpler templating
+ syntax. So what if we combined the two strengths? Thus, Smarty was
+ born...

+
+ Smarty For Programmers
+
+
+
+ Constants
+
+
+
+ SMARTY_DIR
+
+ This should be the full system path to the location of the Smarty
+ class files. If this is not defined, then Smarty will attempt to
+ determine the appropriate value automatically. If defined, the path
+ must end with a slash.
+
+
+ SMARTY_DIR
+
+// set path to Smarty directory
+define("SMARTY_DIR","/usr/local/lib/php/Smarty/");
+
+require_once(SMARTY_DIR."Smarty.class.php");
+
+
+
+
+
+ Variables
+
+
+ $template_dir
+
+ This is the name of the default template directory. If you do
+ not supply a resource type when including files, they will be
+ found here. By default this is "./templates", meaning that it
+ will look for the templates directory in the same directory as
+ the executing php script.
+
+
+ Technical Note
+
+ It is not recommended to put this directory under
+ the web server document root.
+
+
+
+
+ $compile_dir
+
+ This is the name of the directory where compiled templates are
+ located. By default this is "./templates_c", meaning that it
+ will look for the compile directory in the same directory as
+ the executing php script.
+
+
+ Technical Note
+
+ This setting must be either a relative or
+ absolute path. include_path is not used for writing files.
+
+
+
+ Technical Note
+
+ It is not recommended to put this directory under
+ the web server document root.
+
+
+
+
+ $config_dir
+
+ This is the directory used to store config files used in the
+ templates. Default is "./configs", meaning that it will look
+ for the configs directory in the same directory as the
+ executing php script.
+
+
+ Technical Note
+
+ It is not recommended to put this directory under
+ the web server document root.
+
+
+
+
+ $plugins_dir
+
+ This is the directories where Smarty will look for the plugins that it
+ needs. Default is "plugins" under the SMARTY_DIR. If you supply a
+ relative path, Smarty will first look under the SMARTY_DIR, then
+ relative to the cwd (current working directory), then relative to each
+ entry in your PHP include path.
+
+
+ Technical Note
+
+ For best performance, do not setup your plugins_dir to have to use the
+ PHP include path. Use an absolute pathname, or a path relative to
+ SMARTY_DIR or the cwd.
+
+
+
+
+ $debugging
+
+ This enables the debugging console.
+ The console is a javascript window that informs you of the
+ included templates and assigned variables for the current
+ template page.
+
+
+
+ $debug_tpl
+
+ This is the name of the template file used for the debugging console. By
+ default, it is named debug.tpl and is located in the SMARTY_DIR.
+
+
+
+ $debugging_ctrl
+
+ This allows alternate ways to enable debugging. NONE means no
+ alternate methods are allowed. URL means when the keyword
+ SMARTY_DEBUG is found in the QUERY_STRING, debugging is enabled
+ for that invocation of the script. If $debugging is true, this
+ value is ignored.
+
+
+
+ $undefined
+
+ This sets the value of $undefined for Smarty, default is null.
+ Currently this is only used to set undefined variables in
+ $global_assign to a default value.
+
+
+
+ $autoload_filters
+
+ If there are some filters that you wish to load on every template
+ invocation, you can specify them using this variable and Smarty will
+ automatically load them for you. The variable is an associative array
+ where keys are filter types and values are arrays of the filter
+ names. For example:
+
+
+$smarty->autoload_filters = array('pre' => array('trim', 'stamp'),
+ 'output' => array('convert'));
+
+
+
+
+
+ $compile_check
+
+ Upon each invocation of the PHP application, Smarty tests to see if the
+ current template has changed (different time stamp) since the last time
+ it was compiled. If it has changed, it recompiles that template. If the
+ template has not been compiled, it will compile regardless of this
+ setting. By default this variable is set to true. Once an application is
+ put into production (templates won't be changing), the compile_check
+ step is no longer needed. Be sure to set $compile_check to "false" for
+ maximal performance. Note that if you change this to "false" and a
+ template file is changed, you will *not* see the change since the
+ template will not get recompiled. If caching is enabled and
+ compile_check is enabled, then the cache files will get regenerated if
+ an involved template file or config file was updated. See $force_compile or clear_compiled_tpl.
+
+
+
+ $force_compile
+
+ This forces Smarty to (re)compile templates on every
+ invocation. This setting overrides $compile_check. By default
+ this is disabled. This is handy for development and debugging.
+ It should never be used in a production environment. If caching
+ is enabled, the cache file(s) will be regenerated every time.
+
+
+
+ $caching
+
+ This tells Smarty whether or not to cache the output of the templates.
+ By default this is set to 0, or disabled. If your templates generate
+ redundant redundant content, it is advisable to turn on caching. This
+ will result in significant performance gains. You can also have multiple
+ caches for the same template. A value of 1 or 2 enables caching. 1 tells
+ Smarty to use the current $cache_lifetime variable to determine if the
+ cache has expired. A value of 2 tells Smarty to use the cache_lifetime
+ value at the time the cache was generated. This way you can set the
+ cache_lifetime just before fetching the template to have granular
+ control over when that particular cache expires. See also is_cached.
+
+
+ If $compile_check is enabled, the cached content will be regenerated if
+ any of the templates or config files that are part of this cache are
+ changed. If $force_compile is enabled, the cached content will always be
+ regenerated.
+
+
+
+ $cache_dir
+
+ This is the name of the directory where template caches are
+ stored. By default this is "./cache", meaning that it will look
+ for the cache directory in the same directory as the executing
+ php script. You can also use your own custom cache handler
+ function to control cache files, which will ignore this
+ setting.
+
+
+ Technical Note
+
+ This setting must be either a relative or
+ absolute path. include_path is not used for writing files.
+
+
+
+ Technical Note
+
+ It is not recommended to put this directory under
+ the web server document root.
+
+
+
+
+ $cache_lifetime
+
+ This is the length of time in seconds that a template cache is valid.
+ Once this time has expired, the cache will be regenerated. $caching must
+ be set to "true" for $cache_lifetime to have any purpose. A value of -1
+ will force the cache to never expire. A value of 0 will cause the cache
+ to always regenerate (good for testing only, to disable caching a more
+ efficient method is to set $caching = false.)
+
+
+ If $force_compile is
+ enabled, the cache files will be regenerated every time, effectively
+ disabling caching. You can clear all the cache files with the clear_all_cache() function, or
+ individual cache files (or groups) with the clear_cache() function.
+
+
+ Technical Note
+
+ If you want to give certain templates their own cache lifetime, you could
+ do this by setting $caching = 2,
+ then set $cache_lifetime to a unique value just before calling display()
+ or fetch().
+
+
+
+
+ $cache_handler_func
+
+ You can supply a custom function to handle cache files instead
+ of using the built-in method using the $cache_dir. See the
+ custom cache
+ handler function section for details.
+
+
+
+ $cache_modified_check
+
+ If set to true, Smarty will respect the If-Modified-Since
+ header sent from the client. If the cached file timestamp has
+ not changed since the last visit, then a "304 Not Modified"
+ header will be sent instead of the content. This works only on
+ cached content without insert tags.
+
+
+
+ $config_overwrite
+
+ If set to true, variables read in from config files will overwrite each
+ other. Otherwise, the variables will be pushed onto an array. This is
+ helpful if you want to store arrays of data in config files, just list
+ each element multiple times. true by default.
+
+
+
+ $config_booleanize
+
+ If set to true, config file values of on/true/yes and off/false/no get
+ converted to boolean values automatically. This way you can use the
+ values in the template like so: {if #foobar#} ... {/if}. If foobar was
+ on, true or yes, the {if} statement will execute. true by default.
+
+
+
+ $config_read_hidden
+
+ If set to true, hidden sections (section names beginning with a period)
+ in config files can be read from templates. Typically you would leave
+ this false, that way you can store sensitive data in the config files
+ such as database parameters and not worry about the template loading
+ them. false by default.
+
+
+
+ $config_fix_newlines
+
+ If set to true, mac and dos newlines (\r and \r\n) in config files are
+ converted to \n when they are parsed. true by default.
+
+
+
+ $default_template_handler_func
+
+ This function is called when a template cannot be obtained from
+ its resource.
+
+
+
+ $php_handling
+
+ This tells Smarty how to handle PHP code embedded in the
+ templates. There are four possible settings, default being
+ SMARTY_PHP_PASSTHRU. Note that this does NOT affect php code
+ within {php}{/php}
+ tags in the template.
+
+
+ SMARTY_PHP_PASSTHRU - Smarty echos tags as-is.
+ SMARTY_PHP_QUOTE - Smarty quotes the tags as
+ html entities.
+ SMARTY_PHP_REMOVE - Smarty removes the tags from
+ the templates.
+ SMARTY_PHP_ALLOW - Smarty will execute the tags
+ as PHP code.
+
+
+ NOTE: Embedding PHP code into templates is highly discouraged.
+ Use custom functions or
+ modifiers instead.
+
+
+
+ $security
+
+ $security true/false, default is false. Security is good for
+ situations when you have untrusted parties editing the templates
+ (via ftp for example) and you want to reduce the risk of system
+ security compromises through the template language. Turning on
+ security enforces the following rules to the template language,
+ unless specifially overridden with $security_settings:
+
+
+ If $php_handling is set to SMARTY_PHP_ALLOW, this is
+ implicitly changed to SMARTY_PHP_PASSTHRU
+ PHP functions are not allowed in IF statements,
+ except those specified in the $security_settings
+ templates can only be included from directories
+ listed in the $secure_dir array
+ local files can only be fetched from directories
+ listed in the $secure_dir array using {fetch}
+ {php}{/php} tags are not allowed
+ PHP functions are not allowed as modifiers, except
+ those specified in the $security_settings
+
+
+
+ $secure_dir
+
+ This is an array of all local directories that are considered
+ secure. {include} and {fetch} use this when security is enabled.
+
+
+
+ $security_settings
+
+ These are used to override or specify the security settings when
+ security is enabled. These are the possible settings:
+
+
+ PHP_HANDLING - true/false. If set to true, the
+ $php_handling setting is not checked for security.
+ IF_FUNCS - This is an array of the names of permitted
+ PHP functions in IF statements.
+ INCLUDE_ANY - true/false. If set to true, any
+ template can be included from the file system, regardless of the
+ $secure_dir list.
+ PHP_TAGS - true/false. If set to true, {php}{/php}
+ tags are permitted in the templates.
+ MODIFIER_FUNCS - This is an array of the names of permitted
+ PHP functions used as variable modifiers.
+
+
+
+ $trusted_dir
+
+ $trusted_dir is only for use when $security is enabled. This is an array
+ of all directories that are considered trusted. Trusted directories are
+ where you keep php scripts that are executed directly from the templates
+ with {include_php}.
+
+
+
+ $left_delimiter
+
+ This is the left delimiter used by the template language.
+ Default is "{".
+
+
+
+ $right_delimiter
+
+ This is the right delimiter used by the template language.
+ Default is "}".
+
+
+
+ $compiler_class
+
+ Specifies the name of the compiler class that Smarty will use
+ to compile the templates. The default is 'Smarty_Compiler'. For
+ advanced users only.
+
+
+
+ $request_vars_order
+
+ The order in which request variables are registered, similar to
+ variables_order in php.ini
+
+
+
+ $request_use_auto_globals
+
+ Specifies if Smarty should use php's $HTTP_*_VARS[]
+ ($request_use_auto_globals=false which is the default value) or
+ $_*[] ($request_use_auto_globals=true). This affects templates
+ that make use of {$smarty.request.*}, {$smarty.get.*} etc. .
+ Caution: If you set $request_use_auto_globals to true, variable.request.vars.order
+ has no effect but php's configuration value
+ gpc_order is used.
+
+
+
+ $error_reporting
+
+ When this value is set to a non-null-value it's value is
+ used as php's error_reporting-level inside of display() and
+ fetch(). When debugging is enabled this value is ignored
+ and the error-level is left untouched.
+
+
+
+ $compile_id
+
+ Persistant compile identifier. As an alternative to passing the same
+ compile_id to each and every function call, you can set this compile_id
+ and it will be used implicitly thereafter.
+
+
+
+ $use_sub_dirs
+
+ Set this to false if your PHP environment does not allow the creation of
+ sub directories by Smarty. Sub directories are more efficient, so use them
+ if you can.
+
+
+ Technical Note
+
+ Since Smarty-2.6.2 use_sub_dirs defaults to false.
+
+
+
+
+ $default_modifiers
+
+ This is an array of modifiers to implicitly apply to every variable in a
+ template. For example, to HTML-escape every variable by default, use
+ array('escape:"htmlall"'); To make a variable exempt from default
+ modifiers, pass the special "smarty" modifier with a parameter value of
+ "nodefaults" modifier to it, such as
+ {$var|smarty:nodefaults}.
+
+
+
+ $default_resource_type
+
+ This tells smarty what resource type to use implicitly. The default value
+ is 'file', meaning that $smarty->display('index.tpl'); and
+ $smarty->display('file:index.tpl'); are identical in meaning. See the
+ resource chapter for details.

+
+ void append

+ boolean merge
+
+
+
+ This is used to append an element to an assigned array. If you append
+ to a string value, it is converted to an array value and then
+ appended to. You can explicitly pass name/value pairs, or associative
+ arrays containing the name/value pairs. If you pass the optional third
+ parameter of true, the value will be merged with the current array
+ instead of appended.
+
+
+ Technical Note
+
+ The merge parameter respects array keys, so if you merge two
+ numerically indexed arrays, they may overwrite each other or result in
+ non-sequential keys. This is unlike the array_merge() function of PHP
+ which wipes out numerical keys and renumbers them.

+
+
+
+ This is used to append values to the templates by reference.
+ If you append a variable by reference then change its
+ value, the appended value sees the change as well. For objects,
+ append_by_ref() also avoids an in-memory copy of the appended object.
+ See the PHP manual on variable referencing for an in-depth
+ explanation. If you pass the optional third parameter of true,
+ the value will be merged with the current array instead of appended.

+ If you assign a variable by reference then change its

+ can also pass a compile id as a third parameter. You can "group"
+ templates together so they can be removed as a group. See the

+
+
+ Technical Note
+
+ As of Smarty 2.4.0, assigned template variables are kept across

+
+ Caching
+
+ Caching is used to speed up a call to display() or fetch() by saving its output to a file. If a
+ cached version of the call is available, that is displayed instead of
+ regenerating the output. Caching can speed things up tremendously,
+ especially templates with longer computation times. Since the output of
+ display() or fetch() is cached, one cache file could conceivably be made up
+ of several template files, config files, etc.
+
+
+ Since templates are dynamic, it is important to be careful what you are
+ caching and for how long. For instance, if you are displaying the front page
+ of your website that does not change its content very often, it might work
+ well to cache this page for an hour or more. On the other hand, if you are
+ displaying a page with a weather map containing new information by the
+ minute, it would not make sense to cache this page.
+
+
+ Setting Up Caching
+
+ The first thing to do is enable caching. This is done by setting $caching = true (or 1.)
+
+
+ enabling caching
+
+require('Smarty.class.php');
+$smarty = new Smarty;
+
+$smarty->caching = true;
+
+$smarty->display('index.tpl');
+
+
+ With caching enabled, the function call to display('index.tpl') will render
+ the template as usual, but also saves a copy of its output to a file (a
+ cached copy) in the $cache_dir.
+ Upon the next call to display('index.tpl'), the cached copy will be used
+ instead of rendering the template again.
+
+
+ Technical Note
+
+ The files in the $cache_dir are named similar to the template name.
+ Although they end in the ".php" extention, they are not really executable
+ php scripts. Do not edit these files!
+
+
+
+ Each cached page has a limited lifetime determined by $cache_lifetime. The default value
+ is 3600 seconds, or 1 hour. After that time expires, the cache is
+ regenerated. It is possible to give individual caches their own expiration
+ time by setting $caching = 2. See the documentation on $cache_lifetime for details.
+
+
+ setting cache_lifetime per cache
+
+require('Smarty.class.php');
+$smarty = new Smarty;
+
+$smarty->caching = 2; // lifetime is per cache
+
+// set the cache_lifetime for index.tpl to 5 minutes
+$smarty->cache_lifetime = 300;
+$smarty->display('index.tpl');
+
+// set the cache_lifetime for home.tpl to 1 hour
+$smarty->cache_lifetime = 3600;
+$smarty->display('home.tpl');
+
+// NOTE: the following $cache_lifetime setting will not work when $caching = 2.
+// The cache lifetime for home.tpl has already been set
+// to 1 hour, and will no longer respect the value of $cache_lifetime.
+// The home.tpl cache will still expire after 1 hour.
+$smarty->cache_lifetime = 30; // 30 seconds
+$smarty->display('home.tpl');
+
+
+ If $compile_check is enabled,
+ every template file and config file that is involved with the cache file is
+ checked for modification. If any of the files have been modified since the
+ cache was generated, the cache is immediately regenerated. This is a slight
+ overhead so for optimum performance, leave $compile_check set to false.
+
+
+ enabling $compile_check
+
+require('Smarty.class.php');
+$smarty = new Smarty;
+
+$smarty->caching = true;
+$smarty->compile_check = true;
+
+$smarty->display('index.tpl');
+
+
+ If $force_compile is enabled,
+ the cache files will always be regenerated. This effectively turns off
+ caching. $force_compile is usually for debugging purposes only, a more
+ efficient way of disabling caching is to set $caching = false (or 0.)
+
+
+ The is_cached() function
+ can be used to test if a template has a valid cache or not. If you have a
+ cached template that requires something like a database fetch, you can use
+ this to skip that process.
+
+
+ using is_cached()
+
+require('Smarty.class.php');
+$smarty = new Smarty;
+
+$smarty->caching = true;
+
+if(!$smarty->is_cached('index.tpl')) {
+ // No cache available, do variable assignments here.
+ $contents = get_database_contents();
+ $smarty->assign($contents);
+}
+
+$smarty->display('index.tpl');
+
+
+ You can keep parts of a page dynamic with the insert template function. Let's
+ say the whole page can be cached except for a banner that is displayed down
+ the right side of the page. By using an insert function for the banner, you
+ can keep this element dynamic within the cached content. See the
+ documentation on insert for
+ details and examples.
+
+
+ You can clear all the cache files with the clear_all_cache() function, or
+ individual cache files (or groups) with the clear_cache() function.
+
+
+ clearing the cache
+
+require('Smarty.class.php');
+$smarty = new Smarty;
+
+$smarty->caching = true;
+
+// clear out all cache files
+$smarty->clear_all_cache();
+
+// clear only cache for index.tpl
+$smarty->clear_cache('index.tpl');
+
+$smarty->display('index.tpl');
+
+
+
+ Multiple Caches Per Page
+
+ You can have multiple cache files for a single call to display() or
+ fetch(). Let's say that a call to display('index.tpl') may have several
+ different output contents depending on some condition, and you want
+ separate caches for each one. You can do this by passing a cache_id as the
+ second parameter to the function call.
+
+
+ passing a cache_id to display()
+
+require('Smarty.class.php');
+$smarty = new Smarty;
+
+$smarty->caching = true;
+
+$my_cache_id = $_GET['article_id'];
+
+$smarty->display('index.tpl',$my_cache_id);
+
+
+ Above, we are passing the variable $my_cache_id to display() as the
+ cache_id. For each unique value of $my_cache_id, a separate cache will be
+ generated for index.tpl. In this example, "article_id" was passed in the
+ URL and is used as the cache_id.
+
+
+ Technical Note
+
+ Be very cautious when passing values from a client (web browser) into
+ Smarty (or any PHP application.) Although the above example of using the
+ article_id from the URL looks handy, it could have bad consequences. The
+ cache_id is used to create a directory on the file system, so if the user
+ decided to pass an extremely large value for article_id, or write a script
+ that sends random article_ids at a rapid pace, this could possibly cause
+ problems at the server level. Be sure to sanitize any data passed in before
+ using it. In this instance, maybe you know the article_id has a length of
+ 10 characters and is made up of alpha-numerics only, and must be a valid
+ article_id in the database. Check for this!
+
+
+
+ Be sure to pass the same cache_id as the
+ second parameter to is_cached() and
+ clear_cache().
+
+
+ passing a cache_id to is_cached()
+
+require('Smarty.class.php');
+$smarty = new Smarty;
+
+$smarty->caching = true;
+
+$my_cache_id = $_GET['article_id'];
+
+if(!$smarty->is_cached('index.tpl',$my_cache_id)) {
+ // No cache available, do variable assignments here.
+ $contents = get_database_contents();
+ $smarty->assign($contents);
+}
+
+$smarty->display('index.tpl',$my_cache_id);
+
+
+ You can clear all caches for a particular cache_id by passing null as the
+ first parameter to clear_cache().
+
+
+ clearing all caches for a particular cache_id
+
+require('Smarty.class.php');
+$smarty = new Smarty;
+
+$smarty->caching = true;
+
+// clear all caches with "sports" as the cache_id
+$smarty->clear_cache(null,"sports");
+
+$smarty->display('index.tpl',"sports");
+
+
+ In this manner, you can "group" your caches together by giving them the
+ same cache_id.
+
+
+
+ Cache Groups
+
+ You can do more elaborate grouping by setting up cache_id groups. This is
+ accomplished by separating each sub-group with a vertical bar "|" in the
+ cache_id value. You can have as many sub-groups as you like.
+
+
+ cache_id groups
+
+require('Smarty.class.php');
+$smarty = new Smarty;
+
+$smarty->caching = true;
+
+// clear all caches with "sports|basketball" as the first two cache_id groups
+$smarty->clear_cache(null,"sports|basketball");
+
+// clear all caches with "sports" as the first cache_id group. This would
+// include "sports|basketball", or "sports|(anything)|(anything)|(anything)|..."
+$smarty->clear_cache(null,"sports");
+
+$smarty->display('index.tpl',"sports|basketball");
+
+
+ Technical Note
+
+ The cache grouping does NOT use the path to the template as any part of the
+ cache_id. For example, if you have display('themes/blue/index.tpl'), you
+ cannot clear the cache for everything under the "themes/blue" directory. If
+ you want to do that, you must group them in the cache_id, such as
+ display('themes/blue/index.tpl','themes|blue'); Then you can clear the
+ caches for the blue theme with clear_cache(null,'themes|blue');
+
+
+
+
+
+ Controlling Cacheability of Plugins' Output
+
+Since Smarty-2.6.0 plugins the cacheability of plugins can be declared
+when registering them. The third parameter to register_block,
+register_compiler_function and register_function is called
+$cacheable and defaults to true which is also
+the behaviour of plugins in Smarty versions before 2.6.0
+
+
+
+When registering a plugin with $cacheable=false the plugin is called everytime the page is displayed, even if the page comes from the cache. The plugin function behaves a little like an insert function.
+
+
+
+In contrast to {insert} the attributes to the plugins are not cached by default. They can be declared to be cached with the fourth parameter $cache_attrs. $cache_attrs is an array of attribute-names that should be cached, so the plugin-function get value as it was the time the page was written to cache everytime it is fetched from the cache.
+
+
+
+ Preventing a plugin's output from being cached
+
+index.php:
+
+require('Smarty.class.php');
+$smarty = new Smarty;
+$smarty->caching = true;
+
+function remaining_seconds($params, &$smarty) {
+ $remain = $params['endtime'] - time();
+ if ($remain >=0)
+ return $remain . " second(s)";
+ else
+ return "done";
+}
+
+$smarty->register_function('remaining', 'remaining_seconds', false, array('endtime'));
+
+if (!$smarty->is_cached('index.tpl')) {
+ // fetch $obj from db and assign...
+ $smarty->assign_by_ref('obj', $obj);
+}
+
+$smarty->display('index.tpl');
+
+
+index.tpl:
+
+Time Remaining: {remain endtime=$obj->endtime}
+
+The number of seconds till the endtime of $obj is reached changes on each display of the page, even if the page is cached. Since the endtime attribute is cached the object only has to be pulled from the database when page is written to the cache but not on subsequent requests of the page.
+
+
+
+
+
+ Preventing a whole passage of a template from being cached
+
+index.php:
+
+require('Smarty.class.php');
+$smarty = new Smarty;
+$smarty->caching = true;
+
+function smarty_block_dynamic($param, $content, &$smarty) {
+ return $content;
+}
+$smarty->register_block('dynamic', 'smarty_block_dynamic', false);
+
+$smarty->display('index.tpl');
+
+
+index.tpl:
+
+Page created: {"0"|date_format:"%D %H:%M:%S"}
+
+{dynamic}
+
+Now is: {"0"|date_format:"%D %H:%M:%S"}
+
+... do other stuff ...
+
+{/dynamic}
+
+
+
+When reloading the page you will notice that both dates differ. One is "dynamic" one is "static". You can do everything between {dynamic}...{/dynamic} and be sure it will not be cached like the rest of the page.
+
+
+
+
+
+ Advanced Features
+
+ Objects
+
+ Smarty allows access to PHP objects through the templates. There are
+ two ways to access them. One way is to register objects to the template,
+ then use access them via syntax similar to custom functions. The other way
+ is to assign objects to the templates and access them much like any other
+ assigned variable. The first method has a much nicer template syntax. It
+ is also more secure, as a registered object can be restricted to certain
+ methods or properties. However, a registered object cannot be looped over
+ or assigned in arrays of objects, etc. The method you choose will be
+ determined by your needs, but use the first method whenever possible to
+ keep template syntax to a minimum.
+
+
+ If security is enabled, no private methods or functions can be accessed
+ (begininning with "_"). If a method and property of the same name exist,
+ the method will be used.
+
+
+ You can restrict the methods and properties that can be accessed by
+ listing them in an array as the third registration parameter.
+
+
+ By default, parameters passed to objects through the templates are passed
+ the same way custom functions get them. An associative array is passed
+ as the first parameter, and the smarty object as the second. If you want
+ the parameters passed one at a time for each argument like traditional
+ object parameter passing, set the fourth registration parameter to false.
+
+
+ The optional fifth parameter has only effect with
+ format being true
+ and contains a list ob methods that should be treated as
+ blocks. That means these methods have a closing tag in the
+ template
+ ({foobar->meth2}...{/foobar->meth2}) and
+ the parameters to the methods have the same synopsis as the
+ parameters for block-function-plugins: They get 4 parameters
+ $params,
+ $content,
+ &$smarty and
+ &$repeat and they also behave like
+ block-function-plugins.
+
+
+ using a registered or assigned object
+
+<?php
+// the object
+
+class My_Object {
+ function meth1($params, &$smarty_obj) {
+ return "this is my meth1";
+ }
+}
+
+$myobj = new My_Object;
+// registering the object (will be by reference)
+$smarty->register_object("foobar",$myobj);
+// if we want to restrict access to certain methods or properties, list them
+$smarty->register_object("foobar",$myobj,array('meth1','meth2','prop1'));
+// if you want to use the traditional object parameter format, pass a boolean of false
+$smarty->register_object("foobar",$myobj,null,false);
+
+// We can also assign objects. Assign by ref when possible.
+$smarty->assign_by_ref("myobj", $myobj);
+
+$smarty->display("index.tpl");
+?>
+
+TEMPLATE:
+
+{* access our registered object *}
+{foobar->meth1 p1="foo" p2=$bar}
+
+{* you can also assign the output *}
+{foobar->meth1 p1="foo" p2=$bar assign="output"}
+the output was {$output}
+
+{* access our assigned object *}
+{$myobj->meth1("foo",$bar)}
+
+
+
+ Prefilters
+
+ Template prefilters are PHP functions that your templates are ran through
+ before they are compiled. This is good for preprocessing your templates
+ to remove unwanted comments, keeping an eye on what people are putting
+ in their templates, etc. Prefilters can be either
+ registered or loaded from
+ the plugins directory by using
+ load_filter() function or by
+ setting
+ $autoload_filters variable.
+ Smarty will pass the template source code as the first argument, and
+ expect the function to return the resulting template source code.
+
+
+ using a template prefilter
+
+<?php
+// put this in your application
+function remove_dw_comments($tpl_source, &$smarty)
+{
+ return preg_replace("/<!--#.*-->/U","",$tpl_source);
+}
+
+// register the prefilter
+$smarty->register_prefilter("remove_dw_comments");
+$smarty->display("index.tpl");
+?>
+
+{* Smarty template index.tpl *}
+<!--# this line will get removed by the prefilter -->
+
+
+
+
+ Postfilters
+
+ Template postfilters are PHP functions that your templates are ran through
+ after they are compiled. Postfilters can be either
+ registered or loaded
+ from the plugins directory by using
+ load_filter() function or by
+ setting
+ $autoload_filters
+ variable. Smarty will pass the compiled template code as the first
+ argument, and expect the function to return the result of the
+ processing.
+
+
+ using a template postfilter
+
+<?php
+// put this in your application
+function add_header_comment($tpl_source, &$smarty)
+{
+ return "<?php echo \"<!-- Created by Smarty! -->\n\" ?>\n".$tpl_source;
+}
+
+// register the postfilter
+$smarty->register_postfilter("add_header_comment");
+$smarty->display("index.tpl");
+?>
+
+{* compiled Smarty template index.tpl *}
+<!-- Created by Smarty! -->
+{* rest of template content... *}
+
+
+
+
+ Output Filters
+
+ When the template is invoked via display() or fetch(), its output can be
+ sent through one or more output filters. This differs from postfilters
+ because postfilters operate on compiled templates before they are saved to
+ the disk, and output filters operate on the template output when it is
+ executed.
+
+
+
+ Output filters can be either
+ registered or loaded
+ from the plugins directory by using
+ load_filter() function or by
+ setting
+ $autoload_filters
+ variable. Smarty will pass the template output as the first argument,
+ and expect the function to return the result of the processing.
+
+
+ using a template outputfilter
+
+<?php
+// put this in your application
+function protect_email($tpl_output, &$smarty)
+{
+ $tpl_output =
+ preg_replace('!(\S+)@([a-zA-Z0-9\.\-]+\.([a-zA-Z]{2,3}|[0-9]{1,3}))!',
+ '$1%40$2', $tpl_output);
+ return $tpl_output;
+}
+
+// register the outputfilter
+$smarty->register_outputfilter("protect_email");
+$smarty->display("index.tpl");
+
+// now any occurrence of an email address in the template output will have
+// a simple protection against spambots
+?>
+
+
+
+
+ Cache Handler Function
+
+ As an alternative to using the default file-based caching mechanism, you
+ can specify a custom cache handling function that will be used to read,
+ write and clear cached files.
+
+
+ Create a function in your application that Smarty will use as a
+ cache handler. Set the name of it in the
+ $cache_handler_func
+ class variable. Smarty will now use this to handle cached data. The
+ first argument is the action, which will be one of 'read', 'write' and
+ 'clear'. The second parameter is the Smarty object. The third parameter
+ is the cached content. Upon a write, Smarty passes the cached content
+ in these parameters. Upon a 'read', Smarty expects your function to
+ accept this parameter by reference and populate it with the cached
+ data. Upon a 'clear', pass a dummy variable here since it is not used.
+ The fourth parameter is the name of the template file (needed for
+ read/write), the fifth parameter is the cache_id (optional), and the
+ sixth is the compile_id (optional).
+
+
+ Note: The last parameter ($exp_time) was added in Smarty-2.6.0.
+
+
+ example using MySQL as a cache source
+
+<?php
+/*
+
+example usage:
+
+include('Smarty.class.php');
+include('mysql_cache_handler.php');
+
+$smarty = new Smarty;

+ } else {
+ $contents = $cache_content;

+ $results = mysql_query("replace into CACHE_PAGES values(
+ '$CacheID',
+ '".addslashes($contents)."')
+ ");
+ if(!$results) {

+ break;
+ }
+ mysql_close($link);
+ return $return;
+
+}
+
+?>
+
+
+
+
+ Resources
+
+ The templates may come from a variety of sources. When you display or fetch
+ a template, or when you include a template from within another template,
+ you supply a resource type, followed by the appropriate path and template
+ name. If a resource is not explicitly given the value of $default_resource_type is
+ assumed.
+
+
+ Templates from $template_dir
+
+ Templates from the $template_dir do not require a template
+ resource, although you can use the file: resource for consistancy.
+ Just supply the path to the template you want to use relative to
+ the $template_dir root directory.
+
+
+ using templates from $template_dir
+
+// from PHP script
+$smarty->display("index.tpl");
+$smarty->display("admin/menu.tpl");
+$smarty->display("file:admin/menu.tpl"); // same as one above
+
+{* from within Smarty template *}
+{include file="index.tpl"}
+{include file="file:index.tpl"} {* same as one above *}
+
+
+
+ Templates from any directory
+
+ Templates outside of the $template_dir require the file: template
+ resource type, followed by the absolute path and name of the
+ template.
+
+
+ using templates from any directory
+
+// from PHP script
+$smarty->display("file:/export/templates/index.tpl");
+$smarty->display("file:/path/to/my/templates/menu.tpl");
+
+{* from within Smarty template *}
+{include file="file:/usr/local/share/templates/navigation.tpl"}
+
+
+
+ Windows Filepaths
+
+ If you are using a Windows machine, filepaths usually include a
+ drive letter (C:) at the beginning of the pathname. Be sure to use
+ "file:" in the path to avoid namespace conflicts and get the
+ desired results.
+
+
+ using templates from windows file paths
+
+// from PHP script
+$smarty->display("file:C:/export/templates/index.tpl");
+$smarty->display("file:F:/path/to/my/templates/menu.tpl");
+
+{* from within Smarty template *}
+{include file="file:D:/usr/local/share/templates/navigation.tpl"}
+
+
+
+
+
+ Templates from other sources
+
+ You can retrieve templates using whatever possible source you can
+ access with PHP: databases, sockets, LDAP, and so on. You do this
+ by writing resource plugin functions and registering them with
+ Smarty.
+
+
+
+ See resource plugins
+ section for more information on the functions you are supposed
+ to provide.
+
+
+
+
+ Note that you cannot override the built-in
+ file resource, but you can provide a resource
+ that fetches templates from the file system in some other way by
+ registering under another resource name.
+
+
+
+ using custom resources
+
+// from PHP script
+
+// put these function somewhere in your application
+function db_get_template ($tpl_name, &$tpl_source, &$smarty_obj)
+{
+ // do database call here to fetch your template,
+ // populating $tpl_source
+ $sql = new SQL;
+ $sql->query("select tpl_source
+ from my_table
+ where tpl_name='$tpl_name'");
+ if ($sql->num_rows) {
+ $tpl_source = $sql->record['tpl_source'];
+ return true;
+ } else {
+ return false;
+ }
+}
+
+function db_get_timestamp($tpl_name, &$tpl_timestamp, &$smarty_obj)
+{
+ // do database call here to populate $tpl_timestamp.
+ $sql = new SQL;
+ $sql->query("select tpl_timestamp
+ from my_table
+ where tpl_name='$tpl_name'");
+ if ($sql->num_rows) {
+ $tpl_timestamp = $sql->record['tpl_timestamp'];
+ return true;
+ } else {
+ return false;
+ }
+}
+
+function db_get_secure($tpl_name, &$smarty_obj)
+{
+ // assume all templates are secure
+ return true;
+}
+
+function db_get_trusted($tpl_name, &$smarty_obj)
+{
+ // not used for templates
+}
+
+// register the resource name "db"
+$smarty->register_resource("db", array("db_get_template",
+ "db_get_timestamp",
+ "db_get_secure",
+ "db_get_trusted"));
+
+// using resource from php script
+$smarty->display("db:index.tpl");
+
+{* using resource from within Smarty template *}
+{include file="db:/extras/navigation.tpl"}
+
+
+
+
+ Default template handler function
+
+ You can specify a function that is used to retrieve template
+ contents in the event the template cannot be retrieved from its
+ resource. One use of this is to create templates that do not exist
+ on-the-fly.
+
+
+ using the default template handler function
+
+<?php
+// put this function somewhere in your application
+
+function make_template ($resource_type, $resource_name, &$template_source, &$template_timestamp, &$smarty_obj)
+{
+ if( $resource_type == 'file' ) {
+ if ( ! is_readable ( $resource_name )) {
+ // create the template file, return contents.
+ $template_source = "This is a new template.";
+ $template_timestamp = time();
+ $smarty_obj->_write_file($resource_name,$template_source);
+ return true;
+ }
+ } else {
+ // not a file
+ return false;
+ }
+}
+
+// set the default handler
+$smarty->default_template_handler_func = 'make_template';

+
+
+ Extending Smarty With Plugins
+
+ Version 2.0 introduced the plugin architecture that is used
+ for almost all the customizable functionality of Smarty. This includes:
+
+ functions
+ modifiers
+ block functions
+ compiler functions
+ prefilters
+ postfilters
+ outputfilters
+ resources
+ inserts
+
+ With the exception of resources, backwards compatibility with the old
+ way of registering handler functions via register_* API is preserved. If
+ you did not use the API but instead modified the class variables
+ $custom_funcs, $custom_mods, and
+ other ones directly, then you will need to adjust your scripts to either
+ use the API or convert your custom functionality into plugins.
+
+
+
+ How Plugins Work
+
+ Plugins are always loaded on demand. Only the specific modifiers,
+ functions, resources, etc invoked in the templates scripts will be
+ loaded. Moreover, each plugin is loaded only once, even if you have
+ several different instances of Smarty running within the same request.
+
+
+ Pre/postfilters and output filters are a bit of a special case. Since
+ they are not mentioned in the templates, they must be registered or
+ loaded explicitly via API functions before the template is processed.
+ The order in which multiple filters of the same type are executed
+ depends on the order in which they are registered or loaded.
+
+
+ The plugins directory
+ can be a string containing a path or an array containing multiple
+ paths. To install a plugin, simply place it in one of the
+ directories and Smarty will use it automatically.
+
+
+
+
+ Naming Conventions
+
+ Plugin files and functions must follow a very specific naming
+ convention in order to be located by Smarty.
+
+
+ The plugin files must be named as follows:
+
+
+
+ type.name.php
+
+
+
+
+
+ Where type is one of these plugin types:
+
+ function
+ modifier
+ block
+ compiler
+ prefilter
+ postfilter
+ outputfilter
+ resource
+ insert
+
+
+
+ And name should be a valid identifier (letters,
+ numbers, and underscores only).
+
+
+ Some examples: function.html_select_date.php,
+ resource.db.php,
+ modifier.spacify.php.
+
+
+ The plugin functions inside the plugin files must be named as follows:
+
+
+ smarty_type_name
+
+
+
+
+ The meanings of type and name are
+ the same as before.
+
+
+ Smarty will output appropriate error messages if the plugin file it
+ needs is not found, or if the file or the plugin function are named
+ improperly.
+
+
+
+
+ Writing Plugins
+
+ Plugins can be either loaded by Smarty automatically from the
+ filesystem or they can be registered at runtime via one of the
+ register_* API functions. They can also be unregistered by using
+ unregister_* API functions.
+
+
+ For the plugins that are registered at runtime, the name of the plugin
+ function(s) does not have to follow the naming convention.
+
+
+ If a plugin depends on some functionality provided by another plugin
+ (as is the case with some plugins bundled with Smarty), then the proper
+ way to load the needed plugin is this:
+
+
+require_once $smarty->_get_plugin_filepath('function', 'html_options');
+
+ As a general rule, Smarty object is always passed to the plugins
+ as the last parameter (with two exceptions: modifiers do not get
+ passed the Smarty object at all and blocks get passed
+ &$repeat after the Smarty object to keep
+ backwards compatibility to older versions of Smarty).
+
+
+
+ Template Functions
+
+
+ void smarty_function_name
+ array $params
+ object &$smarty
+
+
+
+ All attributes passed to template functions from the template are
+ contained in the $params as an associative
+ array.
+
+
+ The output (return value) of the function will be substituted in place of the
+ function tag in the template (fetch function, for
+ example). Alternatively, the function can simply perform some other

+
+
+ If the function needs to assign some variables to the template or use
+ some other Smarty-provided functionality, it can use the supplied
+ $smarty object to do so.

+
+ Block Functions
+
+
+ void smarty_block_name
+ array $params
+ mixed $content
+ object &$smarty
+
+
+
+ Block functions are functions of the form: {func} .. {/func}. In other
+ words, they enclose a template block and operate on the contents of
+ this block. Block functions take precedence over custom functions of
+ the same name, that is, you cannot have both custom function {func} and
+ block function {func} .. {/func}.
+
+
+ By default your function implementation is called twice by
+ Smarty: once for the opening tag, and once for the closing tag
+ (see &$repeat below how to change this).
+
+
+ Only the opening tag of the block function may have attributes. All
+ attributes passed to template functions from the template are contained
+ in the $params as an associative array. You can
+ access those values as e.g. $params['start'].
+ The opening tag attributes are also accessible to your function
+ when processing the closing tag.
+
+
+ The value of $content variable depends on
+ whether your function is called for the opening or closing tag. In case
+ of the opening tag, it will be null, and in case of
+ the closing tag it will be the contents of the template block.
+ Note that the template block will have already been processed by
+ Smarty, so all you will receive is the template output, not the
+ template source.
+
+
+
+ The parameter &$repeat is passed by
+ reference to the function implementation and provides a
+ possibility for it to control how many times the block is
+ displayed. By default $repeat is
+ true at the first call of the block-function
+ (the block opening tag) and false on all
+ subsequent calls to the block function (the block's closing tag).
+ Each time the function implementation returns with
+ &$repeat being true, the contents between
+ {func} .. {/func} are evaluated and the function implementation
+ is called again with the new block contents in the parameter
+ $content.
+
+
+
+
+ If you have nested block functions, it's possible to find out what the
+ parent block function is by accessing
+ $smarty->_tag_stack variable. Just do a var_dump()
+ on it and the structure should be apparent.

+
+
+
+ Compiler Functions
+
+ Compiler functions are called only during compilation of the template.
+ They are useful for injecting PHP code or time-sensitive static
+ content into the template. If there is both a compiler function and a
+ custom function registered under the same name, the compiler function
+ has precedence.
+
+
+
+ mixed smarty_compiler_name
+ string $tag_arg
+ object &$smarty
+
+
+
+ The compiler function is passed two parameters: the tag argument
+ string - basically, everything from the function name until the ending
+ delimiter, and the Smarty object. It's supposed to return the PHP code
+ to be injected into the compiled template.

+?>
+
+ This function can be called from the template as:
+
+
+{* this function gets executed at compile time only *}
+{tplheader}
+
+ The resulting PHP code in the compiled template would be something like this:

+
+ Prefilters/Postfilters
+
+ Prefilter and postfilter plugins are very similar in concept; where
+ they differ is in the execution -- more precisely the time of their
+ execution.
+
+
+
+ string smarty_prefilter_name
+ string $source
+ object &$smarty
+
+
+
+ Prefilters are used to process the source of the template immediately
+ before compilation. The first parameter to the prefilter function is
+ the template source, possibly modified by some other prefilters. The
+ plugin is supposed to return the modified source. Note that this
+ source is not saved anywhere, it is only used for compilation.
+
+
+
+ string smarty_postfilter_name
+ string $compiled
+ object &$smarty
+
+
+
+ Postfilters are used to process the compiled output of the template
+ (the PHP code) immediately after the compilation is done but before the
+ compiled template is saved to the filesystem. The first parameter to
+ the postfilter function is the compiled template code, possibly
+ modified by other postfilters. The plugin is supposed to return the
+ modified version of this code.
+
+
+ prefilter plugin

+
+ Output Filters
+
+ Output filter plugins operate on a template's output, after the
+ template is loaded and executed, but before the output is displayed.
+
+
+
+ string smarty_outputfilter_name
+ string $template_output
+ object &$smarty
+
+

+ The first parameter to the output filter function is the template
+ output that needs to be processed, and the second parameter is the
+ instance of Smarty invoking the plugin. The plugin is supposed to do
+ the processing and return the results.

+
+
+ Resources
+
+ Resource plugins are meant as a generic way of providing template
+ sources or PHP script components to Smarty. Some examples of resources:
+ databases, LDAP, shared memory, sockets, and so on.
+
+
+
+ There are a total of 4 functions that need to be registered for each
+ type of resource. Every function will receive the requested resource as
+ the first parameter and the Smarty object as the last parameter. The
+ rest of parameters depend on the function.
+
+
+
+
+ bool smarty_resource_name_source
+ string $rsrc_name
+ string &$source
+ object &$smarty
+
+
+ bool smarty_resource_name_timestamp
+ string $rsrc_name
+ int &$timestamp
+ object &$smarty
+
+
+ bool smarty_resource_name_secure
+ string $rsrc_name
+ object &$smarty
+
+
+ bool smarty_resource_name_trusted
+ string $rsrc_name
+ object &$smarty
+
+
+
+
+ The first function is supposed to retrieve the resource. Its second
+ parameter is a variable passed by reference where the result should be
+ stored. The function is supposed to return true if
+ it was able to successfully retrieve the resource and
+ false otherwise.
+
+
+
+ The second function is supposed to retrieve the last modification time
+ of the requested resource (as a UNIX timestamp). The second parameter
+ is a variable passed by reference where the timestamp should be stored.
+ The function is supposed to return true if the
+ timestamp could be succesfully determined, and false
+ otherwise.
+
+
+
+ The third function is supposed to return true or
+ false, depending on whether the requested resource
+ is secure or not. This function is used only for template resources but
+ should still be defined.
+
+
+
+ The fourth function is supposed to return true or
+ false, depending on whether the requested resource
+ is trusted or not. This function is used for only for PHP script
+ components requested by include_php tag or
+ insert tag with src
+ attribute. However, it should still be defined even for template
+ resources.
