Smarty comes with several custom functions that you can
use in the templates.
{assign}
{assign} is used for assigning template variables
during the execution
of the template.
Example 8-1. {assign} {assign var="name" value="Bob"}
The value of $name is {$name}. |
The above example will output:
The value of $name is Bob. |
|
Example 8-2. Accessing {assign} variables from a PHP script.
To access {assign} variables from php use
get_template_vars().
However, the variables are only available after/during template execution
as in the following example
{* index.tpl *}
{assign var="foo" value="Smarty"} |
<?php
// this will output nothing as the template has not been executed
echo $smarty->get_template_vars('foo');
// fetch the template to a dead variable
$dead = $smarty->fetch('index.tpl');
// this will output 'smarty' as the template has been executed
echo $smarty->get_template_vars('foo');
$smarty->assign('foo','Even smarter');
// this will output 'Even smarter'
echo $smarty->get_template_vars('foo');
?>

template variables.

{include},
{include_php},
{insert},
{counter},
{cycle},
{eval},
