Hi, I'm trying to add settings to a content type form and I'm using organic groups as a guide. I see the form elements for OG being added in the og_ui.module at line 316 in this function og_ui_form_node_type_form_alter but I don't see where these form elements are being submitted, handled, saved, processed... I would've expected it to add another submit handler to the form but it doesn't seem to be the case. Anyone have any experience with this?

  • Wrong place, main things happen on og.module. – Nikit Jun 5 '11 at 4:04
  • right, I figured the og_group_type_(node_type) variable would be set in the main module but I don't see where. How is the info from that form being processed? – Donnyboy Jun 5 '11 at 4:14

This happens automatically.

Adding a variable to that form means that it is automatically saved with variable_set() with a _node_type suffix. Similar to admin forms.

Here is another example: userpoints_nc_visits_form_node_type_form_alter().

As you can see, the form element is for example named userpoints_nc_visits_points and the default value is fetched with userpoints_nc_visits_points_type (inside the get setting api function).
