_menu_build_visible_tree($pid = 0)

Find all visible items in the menu tree, for ease in displaying to user.

Since this is only for display, we only need title, path, and children for each item.

Code

includes/menu.inc, line 1180

<?php
function _menu_build_visible_tree($pid = 0) {
  global $_menu;

    $parent = $_menu['items'][$pid];

    $children = array();
    if (isset($parent['children'])) {
      usort($parent['children'], '_menu_sort');
      foreach ($parent['children'] as $mid) {
        $children = array_merge($children, _menu_build_visible_tree($mid));
      }
    }
    $visible = ($parent['type'] & MENU_VISIBLE_IN_TREE) ||
      ($parent['type'] & MENU_VISIBLE_IF_HAS_CHILDREN && count($children) > 0);
