Smarty comes with several custom functions that you can use in the templates.
{assign} is used for assigning template variables
during the execution of a template.
| 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 |
Example 8.1. {assign}
{assign var='name' value='Bob'}
The value of $name is {$name}.
The above example will output:
The value of $name is Bob.
Example 8.2. {assign} with some maths
This complex example must have the variables in `backticks`
{assign var=running_total value=`$running_total+$some_array[row].some_value`}
Example 8.3. Accessing {assign} variables from a PHP script
To access {assign} variables from a php script use
get_template_vars().
Here's the template that creates the variable $foo.
{assign var='foo' value='Smarty'}
The template variables are only available after/during template execution as in the following script.
<?php
// this will output nothing as the template has not been executed
echo $smarty->get_template_vars('foo');
// fetch the template to a variable
$whole_page = $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');
?>
The following functions can also optionally assign template variables.
{capture},
{include},
{include_php},
{insert},
{counter},
{cycle},
{eval},
{fetch},
{math},
{textformat}
