The Examples project has a complete dependent dropdown example in the AHAH Example. If I were you I would copy it and adapt it. http://drupal.org/project/examples -Randy On Fri, Feb 18, 2011 at 11:05 PM, Jeff Hartman <lists@jeffhartman.com>wrote:
Hey list,
I've got a couple forms that use AHAH functions to generate a drop down of states/provinces based on the user's selection in a country drop down menu.
I'm using a very similar method as is found here: http://drupal.org/node/331941
One form works fine with fields as $form['country'] and $form['state']. The other form uses fieldsets and those fields get renamed and lose their hierarchy after the form is rebuilt.
So for example, the following fields start out like: $form['guest'][1]['country'] $form['guest'][1]['state'] $form['guest'][1]['zip']
But after the form is rebuilt with form_builder and drupal_render using: $output = drupal_render($form['guest'][1]['state']); $output .= drupal_render($form['guest'][1]['zipcode']);
// Render form output as JSON print drupal_json(array('data' => $output, 'status' => true));
The rebuilt fields are logically placed outside of the fieldset and end up as: $form_state['guest'][1]['country'] $form_state['state'] $form_state['zip']
Thoughts on what might cause that? Thanks for any direction. I've struggled with this for hours!
Jeff
