I have 3 select drop-downs, selecting a value in the first populates the second using ajax, selecting the second populates the third. However when I change the value of the first select it doesn't reset the second (If I already chose the first and the second drop down initially).

Method

  • Choose an option from the first
  • This populates the second select with options A, B and C
  • If I change the first one it won't reset the value if that value existed on the first option
  • So if our first option called A, B and C and we change the first drop-down to something else but it calls C, D and E; if C was selected in the second drop-down it doesn't reset since it existed in both ajax calls, this then doesn't load in the third select unless you select a different option in the second select.

Basically what I need is to reset the second and third select whenever the first changes.

  • could be to do with your index's in your options, jQuery onChange wont fire of value doesn't change. Try changing 'event' => 'change' to 'event' => 'click' to see if it's related to that. – jowan sebastian Nov 21 '14 at 19:45
  • can you show the code you're using - it's impossible to guess at what is going on... – Geoff Nov 23 '14 at 17:04
  • @Geoff I included a link to a pastebin, would it be better If I listed the code here? I avoided it cause it's very long. – josephleon Nov 24 '14 at 12:23
  • it's always better not to rely on a link if possible, since the link can change, the site can close, etc. besides, you included the relevant code in your answer, so it's definitely not too long. – Geoff Nov 24 '14 at 16:30

SOLVED

/**
 * The ajax call to return data for the printer model select.
 * @return array             An array of settings.
 */
function first_ajax_callback(&$form, &$form_state) {
  // Reset conditional select values.
  $form['field_printer_model_value']['#value'] = array('All' => 'Select Printer Model');
  $form['field_printer_type_tid']['#value'] = array('All' => 'Select Device Type');

  // $commands = array();
  $commands[] = ajax_command_replace("#second_dropdown", drupal_render($form['field_printer_type_tid']));
  $commands[] = ajax_command_replace("#third_dropdown", drupal_render($form['field_printer_model_value']));

  return array('#type' => 'ajax', '#commands' => $commands);
}

In the above call I set the #value of the selects I want to reset. These lines properly reset two later dependent selects:

$form['field_printer_model_value']['#value'] = array('All' => 'Select Printer Model');
$form['field_printer_type_tid']['#value'] = array('All' => 'Select Device Type');
