Unique Email Validation to prevent duplication form submissions

[uzzislo]

Hi,
I noticed in the validation tutorial that the list of available validations only checks against field content types, e.g., regEx. I'm a novice when it comes to server-side validation and was wondering if there's a way to check against the database to see if a user with a unique email address has already submitted a form with that email address to prevent duplicate submissions per user?

Thanks!

Hi uzzislo,

Welcome to the forums!

Yes, there is a way to tell the script to prevent duplicate submissions, but the one limitation is that your form needs to be an API form. Give this tutorial a read over for more info:

Hope this helps!
