Override admin controller in Magento

Step 1

Create a new module under your local folder, in our case under applocalScommerceCatalog. Now create config.xml with the following -:

<?xml version="1.0" encoding="UTF-8"?>
<config> <modules> <Scommerce_HelloWorld> <version>0.0.1</version> </Scommerce_Catalog> </modules> <admin> <routers> <adminhtml><!--This should be same as defined in Mage_Adminhtml config.xml--> <args> <modules> <Scommerce_HelloWorld before="Mage_Adminhtml"> Scommerce_HelloWorld </Scommerce_HelloWorld> </modules> </args> </adminhtml> </routers> </admin>
</config>

N.B. – Your controller front name should be same as Mage_Adminhtml

Step 2

Create controller Class under localScommerceHelloWorldcontrollersCatalogProductController.php

<?php require_once Mage::getModuleDir('controllers', 'Mage_Adminhtml').DS.'Catalog'.DS.'ProductController.php'; class Scommerce_HelloWorld_Catalog_ProductController extends Mage_Adminhtml_Catalog_ProductController
{ public function editAction() { //your code will go here }
}

Step 3

This is the most important step of all!

Create your module file in etcmodulesScommerce_HelloWorld.xml

 <Scommerce_HelloWorld> <active>true</active> <codePool>local</codePool>
</Scommerce_HelloWorld>
