织梦arclist调用副栏目不显示的解决办法：

打开/include/taglib/arclist.lib.php，代码约位于295-296行,查找以下两行代码：

if($CrossID=='') $orwheres[] = ' arc.typeid IN ('.GetSonIds($typeid).')';
else $orwheres[] = ' arc.typeid IN ('.GetSonIds($typeid).','.$CrossID.')';

改成

$vicewheres = "";
$typeids = explode(",",GetSonIds($typeid));
$crossids = explode(",",$CrossID);
$typeidss = array_merge($typeids,$crossids);
$typeidss = array_unique($typeidss);
foreach($typeidss as $tid){
$liketypeid2 = ",".$tid.",";
$vicewheres.= " or CONCAT(',',arc.typeid2,',') like '%$liketypeid2%' ";
}
if($CrossID==''){
if($vicewheres!="")
$orwheres[] = ' (arc.typeid in ('.GetSonIds($typeid).') '.$vicewheres.') ';
else
$orwheres[] = ' arc.typeid in ('.GetSonIds($typeid).') ';
}else{
if($vicewheres!="")
$orwheres[] = ' (arc.typeid in ('.GetSonIds($typeid).','.$CrossID.') '.$vicewheres.') ';
else
$orwheres[] = ' arc.typeid in ('.GetSonIds($typeid).','.$CrossID.') ';
}
