I would like to add extra consent in checkout on last step.
I made this in PS 1.6 but I have problem in PS 1.7. I spent a lot of time searching any answer. All issues are about inputs in registration form. It's important for me to put it for each cart, no for client account.
1. How to add something in this place by module? I have not found find any appropriate hook. Maybe it's possibe by insert some new consent definition directly to database to some table? I have not found. It seems that is only on / off visibility for this agreement. How to add, maybe in different way, some extra condition to approve with possibility to save it after this step?
2. Which hook is right to save this value in PS 1.7 to cart and order? Hook ActionCartSave or / and ActionValidateOrder?
Please give me any advice.
