使用dedecms多个栏目arclist调用副栏目不显示问题我相信几乎没几个朋友可以解决了,这里看到一站长原创了一篇解决方法非常的不错.
织梦arclist调用副栏目不显示,网上关于这个问题的解决办法有很多,其中一种是.
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).','.$CrossID.')';
将其替换成以下代码:
- if($CrossID=='') $orwheres[] = ' (arc.typeid IN ('.GetSonIds($typeid).') OR arc.typeid2 IN ('.GetSonIds($typeid).')) ';
- else $orwheres[] = ' (arc.typeid IN ('.GetSonIds($typeid).','.$CrossID.') OR arc.typeid2 IN ('.GetSonIds($typeid).','.$CrossID.')) '; //Vevb.com
这种办法可以解决typeid="2"的情况下不显示副栏目的问题,如果typeid=“2,3,8”,有多个栏目需要调用副栏目就不行了.
怎么解决这个问题,找到262行,$orwheres[] = " arc.typeid IN ($typeid) ";
直接替换为:$orwheres[] = " arc.typeid IN ($typeid) or arc.typeid2 IN ($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).

- //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 || emptyempty($refObj->Fields['typeid']))
- {
- $typeids = explode(',', $typeid);
- foreach($typeids as $ttid) {
- $typeidss[] = GetSonIds($ttid);
- }

- $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 = '';
