{call} is used to call a template function defined by the {function} tag just like a plugin function.


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 the name attribute which contains the name of the template function.

  • Values for variables can be passed to the template function as attributes.


Attribute Name Required Description
name Yes The name of the template function
assign No The name of the variable that the output of called template function will be assigned to
[var ...] No 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)}
          {call name=menu data=$entry level=$level+1}

    {* create an array to demonstrate *}
    {$menu = ['item1','item2','item3' => ['item3-1','item3-2','item3-3' =>

    {* 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
