    How to validate automated unique ID generated in submission?

    Asked by visiblelearning on March 06, 2017 at 01:50 AM
    Secondly, is there a way where we would be able to validate an automated generate ID (from a previous form) on our other forms? To be able to effectively track submissions, we want to have people sign up and get an evaluation ID which they then need to use when completing further surveys. We do need this to be validated so no 'fake' numbers are created.

    You can add a Unique ID widget on your form so that you can uniquely identify each submission. Her'es a guide on How to Add Custom Unique IDs to your Form Submissions? But this is not visible in the form.

    If you want to add a unique ID on your form but it should appear to the users, you may consider using the Random Value Generator, which has an option to hide or show the unique generated value and also checks the uniqueness of each generated value to the submissions.


    Hope this helps.
