Description: Main features :Interacts with Paypal's IPN system to monitor when a payment is complete. Automatically generates an email with a unique password which the customer uses to log in to the download area. The purchaser has a defined time limit to download their files and has a defined number of retries. The files are not accessible via a normal href link and hence cannot be downloaded by un-authorised users. The dynamic store front is automatically updated by changes that you make in the admin section. Includes a test page to check the basic operation of the scripts. Incorporates testing via the PayPal Sandbox test environment so that the complete system, including IPN can be tested. Written in PHP and requires mySQL. (Postgress support to be added soon). All credit card transactions are handled by PayPal.
