function gettopname($aid){
 global  $dsql; 
$sql = "SELECT tt.typename,tt.typedir from #@__arctiny as a join #@__arctype as t on a.typeid = t.id join #@__arctype as tt on t.topid=tt.id where a.id = $aid" ; 
$row = $dsql->GetOne($sql);
$typename = $row['typename'];
$typedir = $row['typedir'];
$url = 'http://www.kuitao8.com';
$bodytag = str_replace("{cmspath}",$url,$typedir);
  return $lit_imglist = ''.$typename.'';
}
