织梦多个栏目arclist调用副栏目不显示的解决办法-米微资源分享网

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.')';

　　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 }
