No Duplicates on hidden field

    Hi
    I have created a form that has a hidden field with the label "UID". I use this field to store a custom unique identifier based on a few different user variables.

    Before saving the form I want to check if the UID already exists in the database. If the field was not hidden I could check the "no duplicates" checkbox on the field and it would be validated as required.

    How do I go about achieving this with a hidden field? I have been looking at the "gform_is_duplicate" hook and not had much luck in getting it to work.

    Thanks.

    I'm assuming if the UID already exists you would generate a new one and want to replace the existing one with the new one? Because as it's a hidden field you wouldn't want to throw an error because it's a hidden field...

    Hi Carl
    Thanks for getting back. I have actually come up with a solution and you can see the code here:

    The UID already exists and I would not be updating it with a new one. Your right about throwing an error on a hidden field... my original version of the code did that and the user experience is off. In the end I made it so it threw the error onto all visible fields. Not perfect but it works.
