How to have the 'true' option for a Boolean radio field output first in Drupal 7

If you use a Boolean field with radio buttons in Drupal 7, the false radio button outputs before the true. This became an annoyance to us whilst working on mega-sized forms, so here's our fix. To fix this you'll need to create a custom module, and implement the hook hook_field_widget_form_alter().

The following code assumes your module is called 'example'. All the code does is reverse the order of the options whilst preserving the keys, simple!

/**
 * Implements hook_field_widget_form_alter().
 *
 * Have boolean fields output the true first.
 */
function example_field_widget_form_alter(&$element, &$form_state, $context) {
  if ($context['field']['type'] == 'list_boolean' && isset($element['#options'])) {
    $element['#options'] = array_reverse($element['#options'], TRUE);
  }
}

That's it!

This is really helpful, can't understand why the 'false' is defaulted at the top...

Why is there no link to a Drupal core patch for these 3 trivial lines of code? :)

Darn it you're right! I blame it on the whirlwind of dev that's happening :)
