Is there a good way to add an additional fields to the "Form Settings" area (/wp-admin/admin.php?page=gf_edit_forms) that could be saved with the form's serialized meta information in wp_rg_form_meta? I added some fields using the "gform_advanced_settings" hook but the values are not saving and are not available in $_POST either when I use the "gform_after_save_form" hook.
Here is what I'm working on. We mapped Wordpress accounts to a custom taxonomy called "Groups". When you are logged in you only see content that is "tagged" with groups your account is mapped to - whether that is on the public site or in Wordpress admin. We have a DB table that handles tagging individual GF forms with this taxonomy. This allows us to specify that only a Wordpress admin that is "tagged" with Marketing can see entries from forms tagged with Marketing. The last piece that is missing is how the main administrator can "tag" the GF forms with this custom taxonomy so the permissions get properly set for department admins.
All I need help with is putting some checkboxes onto the Advanced tab of Form Settings in a way that makes them available through gform_after_save_form so I can properly save it into our mapping table.
