I currently have a PHP script that runs the E-Mail List signup page of my Flash site. When the information is entered and the customer clicks "submit" the script automatically emails them a gift certificate with their information printed on the certificate.
NOW, I need the script to do a little more. I need for the Email Address and Verify Email Address fields to verify each other (i.e. both should be exactly the same otherwise they are prompted to re-enter) AND I need the form information the user enters to go into a database on the server for future use. IF the user's Email Address is already present in the database, I want the script to tell them "Sorry this email address has already received this offer" or something to that affect.
