| 织梦程序dedecms网站程序 arclist具体调用副栏目不显示的解决办法。 打开/include/taglib/arclist.lib.php，相关具体代码如下约位于295-296行,查找以下两行相关具体代码如下： if($CrossID=='') $orwheres[] = ' arc.typeid IN ('.GetSonIds($typeid).')'; else $orwheres[] = ' arc.typeid IN ('.GetSonIds($typeid).','.$CrossID.')'; 将其替换成以下相关具体代码如下： $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”，有多个栏目需要具体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原始相关具体代码如下：（ 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('#,#', $typeid) ) //如果typeid字段匹配逗号， 就是说typeid具体调用多个栏目，例如：typeid=“2,3,8” { //指定了getall属性或主页模板例外 if($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'情况下不能具体调用副栏目问题产生的地方 } else //如果typeid不匹配逗号，就是具体调用一个栏目 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'情况下不能具体调用副栏目问题产生的地方 } |
