  theoretically this should work. dont know why it doesnt
  
  
  when i print out $cats right before i return it, the array prints out. BUT nothing returns to the main func from which it was called.
  
  background: i send a categoryID to the function, and it gets all the subcategories, and returns all the subCategoryIDs in an array.
  
  

  Code

  function pnListings_userapi_getCatList($args)
  {
      extract($args);
  
      if (!isset($cid)) {
          $cid = '';
      }
      $cats[] = array('cid' => $cid);
      $subcat = pnModAPIFunc('pnListings',
                           'user',
                           'getCatTree',
                            array('cid' => $cid));
  if(!$subcat) {
  print_r($cats);
  die;
      return $cats;
  
  }
      else
      {
        foreach ( $subcat as $subcatline){
                  pnModAPIFunc('pnListings',
                                       'user',
                                       'getCatList',
                                          array(
                                          'cid' => $subcatline[cid],
                                          'cats' => $cats));
          }
      }
  }

  Code

  $cat = pnModAPIFunc('pnListings',
                           'user',
                           'getCatList',
                            array('cid' => $cid));

  Code

  $cats[] = array('cid' => $cid);

  Code

  $cats = array('cid' => $cid);

  Here's a recursive function that I wrote for my knowledge base:
  
  function steelkb_categories_build($catid='root', $categories_list = array()) {
  //recursive function to build a list of all categories
  
  pnModAPILoad('steelkb', 'user');
  $categories = pnModAPIFunc('steelkb', 'user', 'categories_get', array('parentid' => $catid));
  if($categories) {
  foreach($categories as $category) {
  $categories_list[] = $category['catid'];
  $categories_list = steelkb_categories_build($category['catid'], $categories_list);
  }
  }
  
  return $categories_list;
  }
  
  The API function gets sub categories for the given category.
  
  Hope that helps.

  It looks like you don't actually return the value after the recursive call.

  yes, jed, tht was the problem.
  
  i actually think i like chuck steel's solution, looks cleaner if someone else were to read the code.
  
  
  thanks for the help guys!
