Hi, I use Drupal 6.x. In my own module I alter each node form an add my own validation handler to it using $form['#validate'][] = 'my_own_validation_function'; Then I have the function function my_own_validation_function($form, &$form_state) { //if validation fails, i would like to rebuild the form to add additional form elements in hook_form_alter $form_state['rebuild'] = True; } My problem ist, that the validation functions does not respect my 'rebuild' = True becaus the form is never processed by hook_form_alter after validation. But I need hook_form_alter to add my additional form element. Is there a solution for my problem? Or are form_state changes in an own validation handler not respected even if I set &$form_state as a "pointer"? Thanks and cheers.
