HELLO. I have a database that conatins some codes(Gaming code). I have a landing page that a user should complete an offer. After completing the offer, the user will be redirected to page where he will get a random code from that database. Our problem is that if the user reload the final page again he will get a new code from database and that's what musn't happen. Your job is to make a php script or whatever that generates the final page automatically and pick one random code from the database to show it for the user. After that when the user try to reload the page, he must get the 404 error (Page not found). If you have a better solution to protect our database and allow the user to get only one code everytime he complete an offer on our website, we will be happy with it.
