I need to create a custom enrollment plugin that uses my Universities payment/ verification system. Me and a colleague have already written a perl script for oscommerce that uses my Universities verification/payment system in a shopping cart set up. Can anyone give me pointers on doing this in moodle? Can I just create an html page that allows user to type there credit card information and then post it to the Universities payment/verification box, then if I get an ok from them, add the user to the course? Any help would be appreciated.
