Yii2-GridView 中让关联字段带搜索和排序功能示例

前端之家收集整理的这篇文章主要介绍了Yii2-GridView 中让关联字段带搜索和排序功能示例前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

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Order Model中包含以下代码

hasOne(Customer::className(),['id' => 'customer_id']); }

用gii会自动生成代码

第一步:

在OrderSearch添加一个$customer_name变量

PHP;"> class OrderSearch extends Order { public $customer_name; //<=====就是加在这里 }

第二步:

修改OrderSearch中的search函数

joinWith(['customer']);<=====加入这句 $dataProvider = new ActiveDataProvider([ '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' => 'Customer Name'
],/=============/
]
]);

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

PHP;"> $dataProvider,'filterModel' => $searchModel,'columns' => [ ['class' => 'yii\grid\SerialColumn'],'id','customer_id',['label'=>'客户','attribute' => 'customer_name','value' => 'customer.customer_name' ],//<=====加入这句 ['class' => 'yii\grid\ActionColumn'],],]); ?>
