Hi,
i successfully extended the class Mage_Catalog_Block_Product_View according to those howtos:
- How To Create a Featured Product
- Changing and Customizing Magento Code
But what is the correct way to extend Mage_Core_Model_App?
my extension class in app/code/local/Xxx/Core/Model/App.php
<?php
class Xxx_Core_Model_App extends Mage_Core_Model_App {
public function __construct() {
parent::__construct();
// output to file in order to identify which class is loaded
}
}
?>
my config in app/etc/modules/Xxx_Core.xml
<?xml version="1.0"?>
<config>
<modules>
<Xxx_Core>
<active>true</active>
<codePool>local</codePool>
</Xxx_Core>
</modules>
</config>
my config in app/code/local/Xxx/Core/etc/config.xml
<?xml version="1.0"?>
<config>
<global>
<models>
<core>
<rewrite>
<app>Xxx_Core_Model_App</app>
</rewrite>
</core>
</models>
</global>
</config>
I disabled all caches, but my extension class is not loaded by magento.
And by the way: is there any function for debug output or a variable to append it to?
