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.')';
复制代码
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.') ';
- }
复制代码
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
- }
