function menutrails_primary_links in Menu TrailsMenu Trails 5

This is a substitute function for menu_primary_links()

The important difference is a different criteria for determining if an item is "active" or not, and the use of our own _menu_item() function to make use of that active status.

File

./menutrails.module, line 191

Menutrails allows the assigment of "trails" which will keep menu items active for individual node views.

Code

function menutrails_primary_links($start_level = 1, $pid = 0) {
  if (!module_exists('menu')) {
    return NULL;
  }
  if (!$pid) {
    $pid = variable_get('menu_primary_menu', 0);
  }
  if (!$pid) {
    return NULL;
  }
  if ($start_level < 1) {
    $start_level = 1;
  }
  if ($start_level > 1) {
    $trail = _menu_get_active_trail_in_submenu($pid);
    if (!$trail) {
      return NULL;
    }
    else {
      $pid = $trail[$start_level - 1];
    }
  }
  $menu = menu_get_menu();
  $links = array();

  // Custom data for use down the line
  $trail = _menu_get_active_trail();
  if ($pid && is_array($menu['visible'][$pid]) && isset($menu['visible'][$pid]['children'])) {
    $count = 1;
    foreach ($menu['visible'][$pid]['children'] as $cid) {
      $index = "menu-{$start_level}-{$count}-{$pid}";

      // this needs to be unset
      unset($active);

      // changed from menu_in_active_subtrail
      if (in_array($cid, $trail)) {
        $index .= "-active";

        // we use this below
        $active = TRUE;
      }

      // use $active
      $links[$index] = menutrails_item_link($cid, FALSE, $active);
      $count++;
    }
  }

  // Special case - provide link to admin/build/menu if primary links is empty.
  if (empty($links) && $start_level == 1 && $pid == variable_get('menu_primary_menu', 0) && user_access('administer menu')) {
    $links['1-1'] = array(
      'title' => t('Edit primary links'),
      'href' => 'admin/build/menu',
    );
  }
  return $links;
