Hi again, thank you for your previous inormation.
Since that time I have created EAV those I need, but now I have a problem about how to save them.
I downloaded this module http://kernelhack.com/?p=37 and looked throught it. This is great and easy example if you want to add an additional information to the order.
But I meet a problem - basicaly I can add fields only to the last page of the ‘onepage checkout’ process.
Because my helper is listening for ‘checkout_type_onepage_save_order’ event.
But I need to save an additional information on the billing ‘page’.
I can’t find event from that action (saveBillingAction I beliave).
What to do?
