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.
