In my drupal-based project, we make a difference between laptop users and tablet users: Laptop users can skip some fields when registering, whereas tablet users have to fill in all of them. The trick is easily done by hiding or showing those fields from the signup form with jQuery and Modernizr. And I say trick, because it works, despite some of those hidden fields being marked as
required, they are still allowed to signup without filling on them.
The problem comes when users forget their password and request a link to create a new one.
When they get to the screen of "Enter new password and confirm it", users who have initially signed up via laptop (i.e., not filling on some of the
required fields), cannot continue because they get the error "Fields X and Y cannot be left blank", or sth similar.
I want to disable these 2 fields from being
required for Drupal (not from the signup form, where I have already "hidden" them), but I am not sure how to proceed. Where should I do this?
