dedecms的list標簽orderby屬性只支持按一個字段排序，假如想多個字段排序的話，就需要對PHP舉辦修改，使其可以支持多字段排序，修改如下：

打開include/arc.listview.class.php，找到：
 

//假如不消默認的sortrank或id排序，利用連系查詢（數據量大時很是遲鈍）       if(preg_match('/hot|click|lastpost|title/', $orderby))       {           $query = "SELECT arc.*,tp.typedir,tp.typename,tp.isdefault,tp.defaultname,          tp.namerule,tp.namerule2,tp.ispart,tp.moresite,tp.siteurl,tp.sitepath          $addField          FROM `js_archives` arc          LEFT JOIN `js_arctype` tp ON arc.typeid=tp.id          $addJoin          WHERE {$this->addSql} $ordersql LIMIT $limitstart,$row";       }       //普通環境先從arctiny表查出ID，然后按ID查詢（速度很是快）       else       {           $t1 = ExecTime();           $ids = array();           $query = "SELECT id FROM `js_arctiny` arc WHERE {$this->addSql} $ordersql LIMIT $limitstart,$row ";           $this->dsql->SetQuery($query);           $this->dsql->Execute();           while($arr=$this->dsql->GetArray())           {               $ids[] = $arr['id'];           }           $idstr = join(',',$ids);           if($idstr=='')           {              return '';         }           else           {               $query = "SELECT arc.*,tp.typedir,tp.typename,tp.corank,tp.isdefault,tp.defaultname,                      tp.namerule,tp.namerule2,tp.ispart,tp.moresite,tp.siteurl,tp.sitepath                      $addField                      FROM `js_archives` arc LEFT JOIN `js_arctype` tp ON arc.typeid=tp.id                      $addJoin                      WHERE arc.id in($idstr) $ordersql ";           }           $t2 = ExecTime();           //echo $t2-$t1;         }

替換為：

if($orderby=="default")       {           $t1 = ExecTime();           $ids = array();           $query = "SELECT id FROM `js_arctiny` arc WHERE {$this->addSql} $ordersql LIMIT $limitstart,$row ";           $this->dsql->SetQuery($query);           $this->dsql->Execute();           while($arr=$this->dsql->GetArray())           {               $ids[] = $arr['id'];          }           $idstr = join(',',$ids);           if($idstr=='')           {               return '';           }           else           {               $query = "SELECT arc.*,tp.typedir,tp.typename,tp.corank,tp.isdefault,tp.defaultname,                      tp.namerule,tp.namerule2,tp.ispart,tp.moresite,tp.siteurl,tp.sitepath                      $addField                      FROM `js_archives` arc LEFT JOIN `js_arctype` tp ON arc.typeid=tp.id                      $addJoin                      WHERE arc.id in($idstr) $ordersql ";           }           $t2 = ExecTime();           //echo $t2-$t1;         }        else       {           $query = "SELECT arc.*,tp.typedir,tp.typename,tp.isdefault,tp.defaultname,          tp.namerule,tp.namerule2,tp.ispart,tp.moresite,tp.siteurl,tp.sitepath          $addField          FROM `js_archives` arc          LEFT JOIN `js_arctype` tp ON arc.typeid=tp.id          $addJoin          WHERE {$this->addSql} $ordersql LIMIT $limitstart,$row";       }

找到：

	else {            $ordersql=" ORDER BY arc.sortrank $orderWay";      }

替換為:
 

else if($orderby=="default"){            $ordersql=" ORDER BY arc.sortrank $orderWay";        }        else{           $ordersql=" ORDER BY ".$orderby.",arc.sortrank $orderWay";        }

此刻在模板中就可以應用了多字段排序了，模板應用如下：

{dede:list pagesize='17' orderby='arc.title desc,arc.id'}
