    Tokens or other methods for preventing multiple submissions

    Asked by analogueteacher on July 25, 2013 at 12:54 PM

    I'd like to create a form that lets customers register products that they have purchased from us. Ideally, I'd like to create a field into which they could enter a unique serial number or token to verify their purchase. Once a serial number has been registered, the form would prevent other users from registering with the same number. 

    Is this possible? If so, how would I do it?

    Thank you in advance.
