Come together with the global Drupal community in Rotterdam, 28 Sept – 1 Oct 2026. Sessions, contribution, connection, and Early Bird savings until 8 June.Hi!
I have a custom content type ('cars') with a CCK field ('year'), and that field is stored in it's own table called 'content_field_cars_year' in the database.
Now, after a user has clicked on the 'Submit'-button on a 'Add Cars'-form, and Before the 'year' value is saved to the database, I'd like to make a final change to the value of the 'year'-field.
Adding a custom submit function to the #submit array of the 'Add Cars' form does not work, because the CCK fields seems to be processed before any #submit functions are called.
I already have a custom module ('Form Overrides') with form_hook_alter implementations on some forms, and I'd like to do these modifications in this module.
If ideas popup, please reply!

DrupalNovice commentedSolved this myself.
Two possible ways of achieving this everyone:
Method 1: Use the Computed Field module, and add the code to that field.
Method 2: Use hook_nodeapi and filter down to the form by a switch-case on $node->type, and after that add an if-statement to filter the code only to execute when the form is submitted. My favorite - no other module dependencies, just pure Drupalcode.
Hope this will help someone!
