I'm making a module for ubercart. It's nearly finished, but now I'm working on the admin page. I want the admin to be able to add options, like the poll module adds choices. The problem I have is that the admin form is generated through drupal_get_form, which leaves the $_POST empty. $_POST['form_build_id'] seems to be needed to get the form from cache. Is there a way that the $_POST['form_build_id'] can be accesses after a drupal_get_form? I read that it could be saved to the $form_state variable, but I don't know how.

drupal_get_form() saves the $_POST array into $form['#post'], I think.

if you want to look at how poll module adds choices, have a look at poll_choice_js(), which doesn't use drupal_get_form(), but does the building itself. It helped me understand the ahah process.

  • I ended up using the ahah helper module which was a little messy as well but brought me all the way in the end. – Toxid Apr 28 '11 at 21:37
