How to override a Magento core block class
Posted on 17. Sep, 2008 by Fido .
This tutorial will show you the proper method for overriding a Mage core class. This will work for Block and Model classes. Controllers are a slightly different story and for another tutorial.

Part of customizing Magento is, of course, creating custom Modules. These allow you to inject functionality anywhere, whether in a “static” block fashion that’s more than static, or a shipping/payment module, or large module to do something as large as integrating a 3rd party system (or multiple systems).

Posted on 03. Sep, 2008 by Fido .

If you have ever wanted to do some sort of PHP processing within a CMS page that you created, here is how you do it.
A limitation of this tutorials is form processing. That involves creating and/or extending and/or overriding a controller class (which I’ll save for another day).
