I have created one custom module for this

and we have specified the our filter to magento by adding the following code in config.xml page

<global>
    <cms>
        <page>
            <tempate_filter>[Namespace]_[Module]_Model_Template_Filter</tempate_filter>
        </page>
        <block>
            <tempate_filter>[Namespace]_[Module]_Model_Template_Filter</tempate_filter>
        </block>
    </cms>
<global>

Then create the file [Namespace]/[Module]/Model/Template/Filter.php

class [Namespace]_[Module]_Model_Template_Filter extends Mage_Widget_Model_Template_Filter
{
    public function helperDirective($construction)
    {
        $params = $this->_getIncludeParameters($construction[2]);
        $allowedParams = array('module', 'method', 'params');
        if(empty($params) || !count(array_intersect($allowedParams, array_keys($params)))){
            return $construction[0];
        }
        if((isset($params['module']) && !empty($params['module'])) && (isset($params['module']) && !empty($params['module']))){
            try{
                $helper = Mage::helper($params['module']);
                if(is_callable(array($helper, $params['method']), true, $params['method'])){
                    $arg = array();
                    $method = $params['method'];
                    if(isset($params['params']) && !empty($params['params'])){
                        $arg = explode(',',$params['params']);
                    }
                    return call_user_func_array(array($helper, $method), $arg);
                }
            } catch (Exception $e){
                return $construction[0];
            }
        }
        return $construction[0];
    }
}

Note: here the function name is helperDirective. if you that to {{custom }} so the function name will customDirective (i.e,{{youname}}Directive)

Then I have use 3 parameters for this.

So you can call your helper function by following way

{{helper module="yourmodule" method="yourfunction" params="arg1,arg2,..etc"}}

here

module => 'module helper name'

method => 'function name'

params => 'parameters of the function'

I have created this module by following this tutorial

  • Its working perfectly mate.Thanks. But i confused about tempate_filter i thought it should be template_filter :) – Zaheerabbas Nov 15 '18 at 7:05
