{call} {#language.function.call}
======
`{call}` is used to call a template function defined by the
[`{function}`](#language.function.function) tag just like a plugin
function.
> **Note**
>
> Template functions are defined global. Since the Smarty compiler is a
> single-pass compiler, The [`{call}`](#language.function.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 the `name` attribute which contains the
the name of the template function.
- Values for variables can be passed to the template function as
[attributes](#language.syntax.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
{* 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
