I have a new ebook for the game world of warcraft and I'm trying to setup the checkout and login/pw creation forms so people can create an account to login to the members area where they will find a link to download the ebook.
The checkout is taken care of by clickbank and once someone purchases the ebook clickbank will automatically redirect them to a "Thank You" page on your site.
How to setup the site:
Theres 2 ways we can do this. We can have a 3 step process. They can be sent to a account creation page first where they fill out their name email etc and also create the login/pw they want to use to enter the members area. The next step would be the payment which is taken care of by clickbank. And the third step is to simply have a login password form put on the "Thank You" page where they login and can then download the ebook.
The second option. Have them go straight to the clickbank checkout and on the "Thank You" page put the account creation form and send them to the login page where they can login and download the book.
Only problem is security. Anyone can discover the "Thank You" page and simply create an account without paying. So i need a solution for this problem.
