Code

function og_menu_node_form_validate($form, &$form_state) {

  // If parent is empty, we remove the link title to force menu module to
  // not create a menu entry.
  if (empty($form_state['values']['menu']['parent'])) {

  }
  else {
    $menus = og_menu_get_group_menus();
    $parents = explode(':', $form_state['values']['menu']['parent']);
    $parent = $parents[0];
    $gids = array();
    $has_menu_access = FALSE;

    // Populate $gids with selected groups
    foreach ($form_state['values']['og_groups'] as $gid => $enabled) {
      if ($enabled) {
        $gids[] = $gid;
      }
    }
    foreach ($menus as $menu) {
