Pass array parameter in helper function within smarty template

[eluser]Unknown[/eluser]
Finally, i wrote a smarty plugin to make an associative array, in case somebody needs that:

Code:

/**
* Smarty {assoc_array(} function plugin
*
* Type:     function<br>
* Name:     assoc_array(<br>
* Date:     Feb 13, 2011<br>
* Purpose:  assigns an associative array  var from two strings (keys,values)<br>
* Examples: {assoc_array keys='key1,key2' values='value1,value2' assign=assocarray }
* Output:   assigns in template var $assocarray = Array ('key1'=>'value1','key2'=>value2)
* @author [email protected]
*/

function smarty_function_assoc_array($params,$template)
{
    $assoc_array = Array();

    $keys = explode(",",$params['keys']);
    $values = explode(",",$params['values']);

    if(count($keys)!=count($values))
    {
     trigger_error("assoc_array: keys count not equal to values count", E_USER_NOTICE);
     return;
    }

    for ($i=0; $i < count($keys); $i++)
    {
        $key = $keys[$i];
        $assoc_array[$key] = $values[$i];
    }        
        
    $template->assign($params['assign'],$assoc_array);        
}

So now i can call within template :

Code:

{assoc_array  keys='src,alt,title'  values={cms_image_url()}|cat:'/admin_logo.jpg,somealt,sometitle' assign='img_props'}
{img($img_props)}
