You want to override a Controller’s action with a custom action.

Magento Enterprise v1.6.0.0

The Solution:

I ran into some issues trying to override a controller’s action yesterday. I think it mainly stems from a version change, but at any rate here’s the “new” way to do it. This comes from a helpful post on the Magento forums.

In this example my custom modules’s namespace is “Spinonesolutions” and I’m going to override the createPostAction in Mage_Customer_AccountController.

Start by creating a bare bones custom module; if you don’t know how to do this check out Magento – Part I : Custom Module.

I’ve only got two files in my custom module; controllers/AccountController.php and etc/config.xml.

config.xml:

<?xml version="1.0" encoding="UTF-8"?>
<config>
<modules>
  <Spinonesolutions_Customer>
    <version>0.0.1</version>
  </Spinonesolutions_Customer>
</modules>
<frontend>
  <routers>
    <!-- This is the frontname to override
    EG: http://mydomainname.com/customer/  -->
    <customer>
      <args>
        <modules>
          <!-- Use the module Spinonesolutions_Customer BEFORE Mage_Customer -->
          <Spinonesolutions_Customer before="Mage_Customer">Spinonesolutions_Customer</Spinonesolutions_Customer>
        </modules>
      </args>
    </customer>
  </routers>
</frontend>
</config>

AccountController.php:

<?php
/**
* Override Customer AccountController
*
* Override the createPost action
*
* @category Mage
* @package Mage_Customer
* @author Will Wright
*/

/*Controllers aren't included automatically, so we include it here so that we can extend it*/
include_once("Mage/Customer/controllers/AccountController.php");
class Spinonesolutions_Customer_AccountController extends Mage_Customer_AccountController {
  public function createPostAction() {
    die('here');
  }
}

That’s it!  You should now have a working override.
