I’ve made some customizations in magento checkout, and now I want to move them to app/local, so I can upgrade Magento without messing my work.
I’ve read the wiki on how to add blocks and extend a model .... but either the documentation is really poor...or I’m just not getting it!
In my particular case, I’m extending some magento classes ( checkout/Block/onepage/billing.php for example ), and adding a new block.
But I can’t get to actually load them!
I’m sure some of you guys must have used some code developed by yourself . Can anybody please help me out?
