反复列出Drupal表单标题

Question

I am trying to list all #titles in a Drupal form module; however, I can't seem to get it to work.

foreach ($form_values as $key => $value) {
   echo $form['myForm'][$key]['#title'];
}

The method above does not return anything. I can list the $key values by doing the following:

foreach (...) {
   echo $key . ' ';
}

but I can't find a way to list the titles (eg, '#title' => t('Name') ) for each form input.

Any help? Thanks!

Your request a bit baffles me, but

function print_title($form) {
  foreach (element_children($form) as $key) {
    print_title($form[$key]);
  }
  if (isset($form['#title'])) {
    // do something with your title
  }
}
