  1. function theme_taxonomy_tree($vid) {

  3.   $tree = array();
  4.   $items = array();
  5.   foreach($terms as $term) {
  6.     $items[$term->tid]['data'] = theme('term_in_tree', $term);
  7.     $tree[$term->tid] =& $items[$term->tid];
  8.     foreach($term->parents as $parent_tid) {
  9.       if($parent_tid != 0) {
  10.         unset($tree[$term->tid]);
  11.         $items[$parent_tid]['children'][$term->tid] =& $items[$term->tid];
