Lesson 10 – Rewrite / Edit Controller Magento

This tutorial is the 10th in this series, if you have not already done it, i suggest you to read the tutorials starting with summary of this series .
There’s a long time that i must write the leçcon 10, this day is finally arrived! The next months i just abandoned the blog, because I do not have much time to post … It’s been a while since I’m talking about a project, i’m still working on and honnestly subscribe to the newsletter because it will provide you an access to my project ! it will be huge !

Finaly there is this famous lesson 10 .. why I have not writen it until now? Because when I did the first blog posts I just did not know how too and I founded it a bit complicated…Since that time now i’ve learned a lot and i’m now magento certified developper Plus…it has been a long road to be there.

ok so now how to make a rewrite of a controller ? Because your module will not khnow where to search for your extended class…you have to make a require in your controller.

   require_once "Mage/Checkout/controllers/CartController.php";

This give you something like:

require_once "Mage/Checkout/controllers/CartController.php";
class Pfay_Checkout_CartController extends Mage_Checkout_CartController
    # Rewrite of indexAction
    public function indexAction() {
        die('your method has been rewrited !!');

the require_once is important if your extends not work (because magento can not autoload that class)

Then your class is taken into account instead of the « classic » CartController of magento, set in the config.xml of your module:

<?xml version="1.0" encoding="UTF-8"?>
             <Pfay_Checkout before="Mage_Checkout">Pfay_Checkout</Pfay_Checkout>

Yes just it and it works! In fact he said « just take the controller Pfay_Checkout in my module before Mage_Checkout like that it loads my class, then this class extends the previous require_once class … and now it works.

Well this article was not so long to do it … in fact I hope it will help someone and it will be useful for you. Sometimes you just have to take the time but after a day of work and training we are tired and we think about thing differently ! All this to say that I would post more often and I thank you for reading this blog :) It is you who motivate me to write and all your messages and comments make me very happy. Thank you again :)

Posted in magento.

A Question ? Ask me now ! On :

  1. Just to clear something up: using before in your XML means that your class will be used INSTEAD of the one normally, and after means that it will be used AFTER the one normally loaded
