Anyone have PayPal PHP source to allow customer to enter multiple fields
Just wondering if anyone has a the source code for setting up a PayPal page which allows the customer to:
1. Enter some information (eg. fav colour)
2. Enter some more information (eg. fav number)
3. Back end validates if the colour they entered is a colour and their fav number is in fact a number.
4. If it’s invalid it displays an error message else it takes them to PayPal checkout page where they pay.
5. Upon successful payment, email them “your fav colour is _____ and your fav number is ____”. Doesn’t have to email, I just want their fav colour and number as a variable at the end. Confused how I can get PayPal to send this to the PayPal listener
Obviously this is a mock up scenario
