Override Extension Helper

Question

I'm trying to override a part of an helper of Help Desk MX extension. So I created a module with the following file: app/etc/modules/company.xml

<?xml version="1.0" encoding="utf-8"?>
<config>
     <modules>
        <Company_Helpdesk>
            <active>true</active>
            <codePool>local</codePool>
        </Company_Helpdesk>
    </modules>
</config>

app/code/local/Company/Helpdesk/etc/config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Company_Helpdesk>
            <version>1.0.0</version>
        </Company_Helpdesk>
    </modules>
    <global>
        <helpers>
            <mirasvit_helpdesk>
                <rewrite>
                    <email>Company_Helpdesk_Helper_Email</data>
                </rewrite>
            </mirasvit_helpdesk>
        </helpers>
    </global>
</config>

app/code/local/Company/Helpdesk/Helper/Email.php

<?php
class Company_Helpdesk_Helper_Email extends Mirasvit_Helpdesk_Helper_Email
{
    public function getHiddenSeparator()
    {
        return "<span style='color:transparent;font-size:0;margin:0px;padding:0px;'>".$this->getSeparator().'</span>';
    }   
}

Following this guide: http://inchoo.net/magento/overriding-magento-blocks-models-helpers-and-controllers/

But it doesn't work.

Where am I wrong?

Answer 1

change this in your config.xml

<global>
    <helpers>
        <mirasvit_helpdesk>
            <rewrite>
                <email>Company_Helpdesk_Helper_Email</email>
            </rewrite>
        </mirasvit_helpdesk>
    </helpers>
</global>

to this

<global>
    <helpers>
        <helpdesk><!-- this needs to match the tag in the original module -->
            <rewrite>
                <email>Company_Helpdesk_Helper_Email</email>
            </rewrite>
        </helpdesk>
    </helpers>
</global>

also, in your app/etc/modules/company.xml add this inside the Company_Helpdesk tag

<depends>
     <Mirasvit_Helpdesk />
</depends>

Here i am show you how to Extend community Or third party module helper class in your own modules. Now here i am extend asmaty extension helper.

1. create your module register xml app/etc/modules/Myextend_Shopbyextend.xml

   <?xml version="1.0"?> <config> <modules> <Myextend_Shopbyextend> <active>true</active> <codePool>local</codePool> <depends> <Amasty_Shopby /> </depends> </Myextend_Shopbyextend> </modules> </config>

2. create module config.xml file app/code/local/Myextend/Shopbyextend/etc/

<?xml version="1.0"?> <config> <modules> <Myextend_Shopbyextend> <version>0.1.0</version> </Myextend_Shopbyextend> </modules> <global> <helpers> <shopbyextend> <class>Myextend_Shopbyextend_Helper</class> </shopbyextend> <amshopby> <rewrite> <data>Myextend_Shopbyextend_Helper_Data</data> </rewrite> </amshopby> </helpers>
</global> </config>
