如何解决呢?元素模板为您解答
修改文件\include\taglib\arclist.lib.php
第295行
if($CrossID=='') $orwheres[] = ' arc.typeid IN ('.GetSonIds($typeid).')';else $orwheres[] = ' arc.typeid IN ('.GetSonIds($typeid).','.$CrossID.')';
替换成
if($CrossID=='')$orwheres[] = " (arc.typeid in (".GetSonIds($typeid).") or arc.typeid2 in (".GetSonIds($typeid).") or CONCAT( ',', arc.typeid2, ',' ) LIKE '%,".$typeid.",%' )";else$orwheres[] = " (arc.typeid in (".GetSonIds($typeid).",".$CrossID.") or arc.typeid2 in (".GetSonIds($typeid).",".$CrossID.") or CONCAT( ',', arc.typeid2, ',' ) LIKE '%,".$typeid.",%')";
