Yii2-GridView 中让关联字段带搜索和排序功能示例
情境要求:
要在订单(Order)视图的gridview中显示出客户(Customer)姓名,并使其具有与其它字段相同的排序和搜索功能。
数据库结构
订单表order含有字段customer_id与客户表customer的id字段关联
首先确保在OrderModel中包含以下代码:
publicfunctiongetCustomer() { return$this->hasOne(Customer::className(),['id'=>'customer_id']); }
用gii会自动生成此代码;
第一步:
在OrderSearch添加一个$customer_name变量
classOrderSearchextendsOrder { public$customer_name;//<=====就是加在这里 }
第二步:
修改OrderSearch中的search函数
publicfunctionsearch($params) { $query=Order::find(); $query->joinWith(['customer']);<=====加入这句 $dataProvider=newActiveDataProvider([ 'query'=>$query, ]); $dataProvider->setSort([ 'attributes'=>[ /*其它字段不要动*/ /*下面这段是加入的*/ /*=============*/ 'customer_name'=>[ 'asc'=>['customer.customer_name'=>SORT_ASC], 'desc'=>['customer.customer_name'=>SORT_DESC], 'label'=>'CustomerName' ], /*=============*/ ] ]); if(!($this->load($params)&&$this->validate())){ return$dataProvider; } $query->andFilterWhere([ 'id'=>$this->id, 'user_id'=>$this->user_id, 'customer_id'=>$this->customer_id, 'order_time'=>$this->order_time, 'pay_time'=>$this->pay_time, ]); $query->andFilterWhere(['like','status',$this->status]); $query->andFilterWhere(['like','customer.customer_name',$this->customer_name]);//<=====加入这句 return$dataProvider; }
第三步:
修改order/index视图的gridview
<?=GridView::widget([ 'dataProvider'=>$dataProvider, 'filterModel'=>$searchModel, 'columns'=>[ ['class'=>'yii\grid\SerialColumn'], 'id', 'customer_id', 'status', ['label'=>'客户','attribute'=>'customer_name','value'=>'customer.customer_name'],//<=====加入这句 ['class'=>'yii\grid\ActionColumn'], ], ]);?>
