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.t
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.')';
  将其替换成以下代码:
        $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.') ';       
                    }   
这种办法可以解决typeid="2"的情况下不显示副栏目的问题, 如果typeid=“2,3,8”,有多个栏目需要调用副栏目就不行了  怎么解决这个问题,找到262行, $orwheres[] = " arc.typeid IN ($typeid) "; 直接替换为:
$vicewheres = "";       
               foreach($typeid as $tid){       
                $liketypeid2 = ",".$tid.",";       
                   $vicewheres.= " or CONCAT(',',arc.typeid2,',') like '%$liketypeid2%' ";       
               }       
            if($vicewheres!="")       
                $orwheres[] = " (arc.typeid in ($typeid) $vicewheres) ";       
            else       
                $orwheres[] = " arc.typeid in ($typeid) ";  
问题产生的原因,看下arclist.lib.php原始代码:( typeid为主栏目id, typeid2为副栏目id)
    找到246行:
      //指定了多个栏目时,不再获取子类的id       if( preg_match('#,#', $typeid) )    //如果typeid字段匹配逗号, 就是说typeid调用多个栏目,例如:typeid=“2,3,8”
             {
                //指定了getall属性或主页模板例外
                if($getall==1 || empty($refObj->Fields['typeid']))
                {
                    $typeids = explode(',', $typeid);
                    foreach($typeids as $ttid) {
                        $typeidss[] = GetSonIds($ttid);
                    }
                    $typeidStr = join(',', $typeidss);
                    $typeidss = explode(',', $typeidStr);
                    $typeidssok = array_unique($typeidss);
                    $typeid = join(',', $typeidssok);
                }

                $orwheres[] = " arc.typeid IN ($typeid)";  //导致typeid='2,3,8'情况下不能调用副栏目问题产生的地方
            }
            else   //如果typeid不匹配逗号,就是调用一个栏目 例如 typeid="2"
            {
               //处理交叉栏目
                $CrossID = '';
                if($ctag->GetAtt('cross')=='1')
                {
                    $arr = $dsql->GetOne("SELECT `id`,`topid`,`cross`,`crossid`,`ispart`,`typename` FROM `dede_arctype` WHERE id='$typeid' ");
                    if( $arr['cross']==0 || ( $arr['cross']==2 && trim($arr['crossid']=='') ) )
                    {
                        $orwheres[] = ' arc.typeid IN ('.GetSonIds($typeid).')';
                  }
                    else
                    {
                        $selquery = '';
                        if($arr['cross']==1) {
                            $selquery = "SELECT id,topid FROM `dede_arctype` WHERE typename LIKE '{$arr['typename']}' AND id<>'{$typeid}' AND topid<>'{$typeid}'  ";
                        }
                        else {
                            $arr['crossid'] = preg_replace('#[^0-9,]#', '', trim($arr['crossid']));
                            if($arr['crossid']!='') $selquery = "SELECT id,topid FROM `dede_arctype` WHERE id IN('{$arr['crossid']}') AND id<>'{$typeid}' AND topid<>'{$typeid}'  ";
                        }
                        if($selquery!='')
                        {
                            $dsql->SetQuery($selquery);
                            $dsql->Execute();
                            while($arr = $dsql->GetArray())
                            {
                                $CrossID .= ($CrossID=='' ? $arr['id'] : ','.$arr['id']);
                            }
                        }
                    }
                }
                if($CrossID=='') $orwheres[] = ' arc.typeid IN ('.GetSonIds($typeid).')';
                else $orwheres[] = ' arc.typeid IN ('.GetSonIds($typeid).','.$CrossID.')'; //导致typeid='2'情况下不能调用副栏目问题产生的地方
            }
