I need your help creating code (php?) and maybe also a database(?) to allow me to offer a one-time download of a product that I am selling to ONLY the buyer - using his verified email address. Here is how I think this would/could work: 1) The user clicks on BUY THIS and enters his CC info and email address (at least) 2) My website (which is built using Wordpress) automatically sends out the purchase verification and download instructions 3) The user clicks on the link for the download and downloads the file 4) IF the url is accessed again (perhaps by the user's friend), then the file is no longer available for download (either the filename changed, the location, etc.) Basically, I want to minimize the number of non-purchased products that get downloaded. Certainly the user could upload the file elsewhere or share it, but I don't think they'll bother. To be clear, all I need is #2 and #4 above. What can you offer? Do you have a more secure solution to my problem? Keywords: MySQL, PHP, Wordpress
