    How can I validate a field based on a database list?

    Asked by redrhinotv on April 21, 2015 at 02:24 PM

    We have two serial number type fields on our form, and we'd like the form to automatically cross-check the user's entry with a list of valid serial numbers that we can provide.

    Is this possible?  Appreciate your help.

    Thank you for contacting us.

    Unfortunately, there is no built-in database to form integration options available at JotForm. If you need a custom functionality you might consider modifying a form source code.

    How to get the Full Source Code of your Form

    If the amount of the serial numbers is not big, it might be possible to use conditional logic. In this case, you will need to add the serial numbers via JotForm and setup your conditional actions.
