I'm looking for a tell a friend feature that would work the following way. When somebody emails their friends about my site and then one of those friends visits my site and makes a purchase (I use paypal) the referrer gets a certain discount on his next purchase. The discount should accumulate, so that after a certain number of friends make purchases the referrer gets free product.
I'm looking for a php script. I run on a Linux server and use MySQL database. I will need the script to be installed on my site.
1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request.
3) Exclusive and complete copyrights to all work purchased. (No GPL, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site).
