Functions
Every Smarty tag either prints a
variable or invokes some sort
of function. These are processed and displayed by enclosing the
function and its
attributes
within delimiters like so:
{funcname attr1='val1' attr2='val2'}.
function syntax
{$name}!
{else}
hi, {$name}
{/if}
{include file='footer.tpl' ad=$random_id}
]]>
Both built-in functions
and custom functions
have the same syntax within templates.
Built-in functions are the
inner workings of Smarty, such as
{if},
{section} and
{strip}.
There should be no need to change or modify them.
Custom functions are
additional
functions implemented via plugins.
They can be modified to your liking, or you can create new ones.
{html_options} and
{popup}
are examples of custom functions.
