The validateUnique() and validateUniqueMultiple() functions don't evaluate #unique = false correctly

Open on Drupal.org →
Created on 28 August 2025, 25 days ago

Problem/Motivation

If you have a form element that is coded as #unique: false, it's treated as though it's #unique: true.

Steps to reproduce

I wasn't able to get the admin UI to create a #unique: false setting on an element, but it can be done on the Source page. In my case, I think I ended up with some of these as a result of migrating forms with Webform Migrate → .

Proposed resolution

The #unique key is currently being checked with isset(). It should be checked with empty() instead.
