Code

function _hierarchical_select_process_get_hs_selection($element) {
  $hs_selection = array();
  $config = _hierarchical_select_inherit_default_config($element['#config']);
  if (!empty($element['#value']['hierarchical_select']['selects'])) {
    if ($config['save_lineage']) {
      foreach ($element['#value']['hierarchical_select']['selects'] as $key => $value) {
        $hs_selection[] = $value;
      }
    }
    else {
      foreach ($element['#value']['hierarchical_select']['selects'] as $key => $value) {
        $hs_selection[] = $value;
      }
      $hs_selection = _hierarchical_select_hierarchy_validate($hs_selection, $config['module'], $config['params']);

      // Get the last valid value. (Only the deepest item gets saved). Make
      // sure $hs_selection is an array at all times.
      $hs_selection = $hs_selection != -1 ? array(
        end($hs_selection),
      ) : array();
    }
  }
  return $hs_selection;
