Magento Developper’s Guide (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 .

Now how to make a rewrite of a controller ? Because your module will not know 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 Easylife_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"?>

<config>

   ...

<frontend>

<routers>

     <checkout>

         <args>

           <modules>

             <Easylife_Checkout before="Mage_Checkout">Easylife_Checkout</Easylife_Checkout>

           </modules>

         </args>

     </checkout>

   </routers>

</frontend>

</config>

 

Yes just it and it works! In fact « just take the controller Easylife_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
