|

Smarty is a template engine for PHP. One of the unique aspects about
|

Smarty that sets it apart from other templating solutions is that it
|

precompiles the templates into native php scripts upon the first
|
||||
execution, then executes the php scripts from that point forward.

compiles the templates into native php scripts upon the first
|

execution. After that, it just executes the compiled PHP scripts.

Therefore, there is no costly template file parsing for each request.

Smarty also has built-in page caching to minimize the regeneration

of unchanged content.

* 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

{}, {{}}, <!--{}-->, or whatever your fancy.

* template if/else/endif constructs are passed to the PHP parser,

so the if syntax can be as simple or as complex as you like

VARIABLE TYPES:
|
||||

Smarty has two different syntaxes for variables. One for script
|
||||
variables (prefixed with $), and one for internal variables
|
||||
generated by the template parser (prefixed and suffixed with %).
|
||||
Smarty has three different syntaxes for variables. One for script
|
||||
variables (prefixed with $), one for config file variables
|
||||
which are surrounded by # symbols, and one for variables that
|
||||
are internal to the template language, which are surrounded by
|
||||
% symbols.
|
||||
|
||||
Variable examples:
|
||||
{$Name} <-- prints the value of $Name
|
||||
{%News.rownum%} <-- prints the current iteration
|
||||
of the section named "News"
|
||||
{if %News.rownum% is even} <-- checks if the rownum is even

{#tableBgColor#} <-- prints variable from config file

arguments in the correct order, you can write a variable

modifier "wrapper" that passes them in the correct order.
|

For instance, strftime() expects the date format first,

followed by the date. You can write a wrapper that passes

followed by the date. Smarty comes with a wrapper that passes

them in the correct order:

{$date|dateFormat:"%Y-%m-%d"}
|

{$date|date_format:"%Y-%m-%d"}

This will pass the value of $date, followed by the specified
|

date format to your variable modifier "dateFormat". This

date format to your variable modifier "date_format". This

can in turn pass the values to strftime() in the correct

order, then return the results.

HINT: always pass dates to Smarty in a unix

date in countless ways with date_format.
