Using Drupal 7.x. Not much experience with Drupal.
I have a core form in which I need to append some data to a field after it's been submitted by the site visitor. I have found I can alter the submitted data with a form_alter function added to my own custom module. It works fine as far as that, but after the "prepare", $check_cache reverts values.
Is there a way to make this work?
Is there a way to manipulate the "uncacheable keys" to include my item?
Is there a different way to massage submitted data other than hacking the code?
Any other suggestions?
