dedecms arclist 无法调用副栏目文章的解决办法

1、打开include/taglib/arclist.lib.php,找到296行：if($CrossID=='') $orwheres[] = ' arc.typeid IN ('.GetSonIds($typeid).')'; else $orwheres[] = ' arc.typeid IN ('.GetSonIds($typeid).','.$CrossID.')';

2、替换成以下即可：if($CrossID=='')$orwheres[] = ' (arc.typeid IN ('.GetSonIds($typeid).') OR arc.typeid2 IN ('.GetSonIds($typeid).') or FIND_IN_SET('.$typeid .', arc.typeid2)>0)';else$orwheres[] = ' (arc.typeid IN ('.GetSonIds($typeid).','.$CrossID.') OR arc.typeid2 IN ('.GetSonIds($typeid).','.$CrossID.')or FIND_IN_SET('.$typeid .',arc.typeid2)>0)';

3、然后再更新一下系统缓存即可。
