I have actually come up with a solution and you can see the code here:</p> <p><a href="https://gist.github.com/913464" rel="nofollow">https://gist.github.com/913464</a></p> <p>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.</p> <p>Scott </p> https://legacy.forums.gravityhelp.com/topic/no-duplicates-on-hidden-field#post-22790 Fri, 08 Apr 2011 11:38:49 +0000 Carl Hancock 22790@https://legacy.forums.gravityhelp.com/ <p>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... </p> https://legacy.forums.gravityhelp.com/topic/no-duplicates-on-hidden-field#post-22765 Fri, 08 Apr 2011 05:54:40 +0000 toggle 22765@https://legacy.forums.gravityhelp.com/ <p>Hi<br /> 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.</p> <p>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. </p> <p>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.</p> <p>Thanks. </p>
