$id = (int) $modx->getOption('id', $scriptProperties);
if (!isset($scriptProperties['id'])) {
    $id = $modx->resource->get('id');
}
$q = $modx->newQuery('modResource');
$q->where(array(
   'parent' => $id,
   'deleted' => 0,
   'published' => 1,
   'hidemenu' => 0
));
$counter = $modx->getCount('modResource', $q);
