Code

function menu_link_weight_node_form_submit($form, &$form_state) {

  // For graceful JS degradation.
  if ($form_state['triggering_element']['#value'] == menu_link_weight_get_button_text()) {

  // Return on empty submissions or if if 'Provide a menu link' not selected.

    return;
  }
  $transaction = db_transaction();
  try {

    // Because the form elements were keyed with the item ids from the database,
    // we can simply iterate through the submitted values.
    foreach ($form_state['values']['menu']['menu_link_weight'] as $mlid => $info) {
      if ($mlid == 'link_current') {

        // Do nothing. Changing the weight of the current link will be handled
        // in hook_node_submit() instead.
        continue;
