Ok, I just need to add another "ajax drop down" payment option to my checkout process, right alongside the "credit card" that's available right now.
I just need it to do this:
- display a radio box to check it as a payment option (instead of the default Credit Card one)
- when checked, use that fancy ajax drop down to display a single text input field to capture a 20 character long string
- when the order is reviewed, the string is displayed on the review order page
- after submitting the order, all I need to do is to store that custom input string along with the order (in the archive) so that the admin can review it, match it with an existing offline database and process the payment manually.
So basically, how do I create a checkout option that doesn't validate anything, just accepts a string and stores it with the order for the admin to view?
