Помогите изменить сниппет для генерации плейлистов в плеере uppod с MODX CMF на DLE

<?php
// Returns UPPOD playlist
$id = isset($_GET['album'])?intval($_GET['album']):intval($modx->getPlaceholder('id'));
$items = $modx->getActiveChildren($id,'menuindex','ASC','pagetitle,content');
$_RET = '{"playlist":[';
foreach($items as $val){
$_RET.= '{"comment":"'.$val['pagetitle'].'","file":"'.$val['content'].'"}';
}
$_RET.= ']}';
return str_replace('}{','},{',$_RET);
?>

<?php
$_getFrom = 0;
if (isset($getFrom)) if (intval($getFrom) > 0) $_getFrom = intval($getFrom);
if ($_getFrom==0) if (isset($_GET['album'])) $_getFrom = intval($_GET['album']);
if ($_getFrom!=0) {
$ret = '{"playlist":[';
$q = $modx->newQuery('modResource');
$q->where(array('parent'=>$_getFrom));
$r = $modx->getCollection('modResource',$q);
foreach($r as $song) {
$ret.= '{"comment":"'.$song->get('pagetitle').'","file":"'.$song->get('content').'"}';
}
$ret.= ']}';
} else { $ret = '{"error":"404"}'; }
return str_replace('}{','},{',$ret);
