if($CrossID==''){
　　$typeid2like = " '%,".GetSonIds($typeid).",%' ";
　　$orwheres[] = " (arc.typeid IN (".GetSonIds($typeid).") OR CONCAT(',', arc.typeid2, ',') LIKE $typeid2like ) ";
}else{
   $typeid2like = " '%,".GetSonIds($typeid).",".$CrossID.",%' ";
   $orwheres[] = " (arc.typeid IN (".GetSonIds($typeid).",".$CrossID.") OR CONCAT(',', arc.typeid2, ',') LIKE $typeid2like) ";
}
