I want to filter the addresses in the checkout process. For that I have to overwrite the function
One way would be: take the file
Abstract.php out of
local. But that is a very dirty way, and I am not sure if I could just take out one file or if I had to take the hole Checkout module into the
local folder? (that as a small side question)
What I search is a clean and good way to do what I want to do.
Can you lead me in the right direction?
