I am totally new to Magento. Still learning, so I am confused about where to start off when I have to do something new.
I have to add just another input field in the checkout that gets saved in the order and displayed in the back-end.
So can someone give me directions? It can probably be implemented in an existing extension, but I don’t really have a clue. Any help and explanation will be greatly appreciated.
UPDATE: For example, I need to take the number of the customer (when he places and order/checks out), save this number and display it in the Order view in the back-end.
What I suppose needs to be done is that I have to fetch this number from the front-end, fire an event which will call a function (from the Observer class) that will set the value of this fetched number into the field in the back-end. But before all that I guess I have to install a script to add this "Customer Number" field in the Order view in the back-end.
