本人5.7 生成列表頁 改動 include/arc.listview.class.php
1.先設定 關閉副欄目(在系統----系統基本引數—效能選項裡)
2.一般網站不需要 欄目交叉 交叉 所以 找到94行註釋掉:
//獲得交叉欄目ID /*if($this->TypeLink->TypeInfos['cross']>0 && $this->TypeLink->TypeInfos['ispart']==0) { $selquery = ''; if($this->TypeLink->TypeInfos['cross']==1) { $selquery = "SELECT id,topid FROM `#@__arctype` WHERE typename LIKE '{$this->Fields['typename']}' AND id<>'{$this->TypeID}' AND topid<>'{$this->TypeID}' "; } else { $this->Fields['crossid'] = preg_replace('/[^0-9,]/', '', trim($this->Fields['crossid'])); if($this->Fields['crossid']!='') { $selquery = "SELECT id,topid FROM `#@__arctype` WHERE id in({$this->Fields['crossid']}) AND id<>{$this->TypeID} AND topid<>{$this->TypeID} "; } } if($selquery!='') { $this->dsql->SetQuery($selquery); $this->dsql->Execute(); while($arr = $this->dsql->GetArray()) { $this->CrossID .= ($this->CrossID=='' ? $arr['id'] : ','.$arr['id']); } } }*/
3.找到751註釋掉:
//獲得附加表的相關資訊 /*$addtable = $this->ChannelUnit->ChannelInfos['addtable']; if($addtable!="") { $addJoin = " LEFT JOIN `$addtable` ON arc.id = ".$addtable.'.aid '; $addField = ''; $fields = explode(',',$this->ChannelUnit->ChannelInfos['listfields']); foreach($fields as $k=>$v) { $nfields[$v] = $k; } if(is_array($this->ChannelUnit->ChannelFields) && !empty($this->ChannelUnit->ChannelFields)) { foreach($this->ChannelUnit->ChannelFields as $k=>$arr) { if(isset($nfields[$k])) { if(!empty($arr['rename'])) { $addField .= ','.$addtable.'.'.$k.' as '.$arr['rename']; } else { $addField .= ','.$addtable.'.'.$k; } } } } } else { $addField = ''; $addJoin = ''; }*/ 再加上$addtable="";
4.找到815行
/*$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 `#@__archives` arc LEFT JOIN `#@__arctype` tp ON arc.typeid=tp.id $addJoin WHERE arc.id in($idstr) $ordersql ";*/ 修改:去掉 $addField $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 FROM `#@__archives` arc LEFT JOIN `#@__arctype` tp ON arc.typeid=tp.id $addJoin WHERE arc.id in($idstr) $ordersql ";
