{call} is used to call a template function defined by the
{function}
tag just like a plugin function.
Note
Template functions are defined global. Since the Smarty compiler is a single-pass compiler,
The {call}
tag must be used to call a template function defined externally from the given template.
Otherwise you can directly use the function as {funcname ...} in the template.
The
{call}tag must have thenameattribute which contains the the name of the template function.Values for variables can be passed to the template function as attributes.
Attributes:
| Attribute Name | Type | Required | Default | Description |
|---|---|---|---|---|
| name | string | Yes | n/a | The name of the template function |
| assign | string | No | n/a | The name of the variable that the output of called template function will be assigned to |
| [var ...] | [var type] | No | n/a | variable to pass local to template function |
Option Flags:
| Name | Description |
|---|---|
| nocache | Call the template function in nocache mode |
Example 7.20. Calling a recursive menu example
{* define the function *}
{function name=menu level=0}
<ul class="level{$level}">
{foreach $data as $entry}
{if is_array($entry)}
<li>{$entry@key}</li>
{call name=menu data=$entry level=$level+1}
{else}
<li>{$entry}</li>
{/if}
{/foreach}
</ul>
{/function}
{* create an array to demonstrate *}
{$menu = ['item1','item2','item3' => ['item3-1','item3-2','item3-3' =>
['item3-3-1','item3-3-2']],'item4']}
{* run the array through the function *}
{call name=menu data=$menu}
{call menu data=$menu} {* short-hand *}
Will generate the following output
* item1
* item2
* item3
o item3-1
o item3-2
o item3-3
+ item3-3-1
+ item3-3-2
* item4
