I am trying to create a web page which allows our users to renew their membership via Paypal. It seemed simple enough at first, except that, in addition to capturing name, address, & email fields, I also want to capture selections relating to what they may be interested in volunteering for.
Attempt #1 was to use formmail with a redirect to Paypal but both services require unique form actions so that didn't work.
Attempt #2 was to use PHP and capture session variables. Use formmail on page 1 to inform me of the name, address, email, and volunteer preferences, then page #2 could use those session variables in conjunction with a Paypal "Buy It Now" button to let users pay their dues. Unfortunately, I can't get the session variables to be recognized within Paypal's structure.
This seems like it should be much simpler than it's turning out to be. Can somebody point me to a good reference source - book, website, etc. that will show me how to do this?
