本文实例讲述了Yii2实现让关联字段支持搜索功能的方法。分享给大家供大家参考,具体如下:
这里有两张表,表结构如下,companies_compay_id 为外键
yii2advanced.branches表:
branch_id:int(11)
companies_company_id:int(11)
branch_name:varchar(100)
branch_address:varchar(255)
branch_created_date:datetime
branch_status:enum('active','inactive')
yii2advanced.companies表:
company_id:int(11)
company_name:varchar(100)
company_email:varchar(100)
company_address:varchar(255)
logo:varchar(200)
company_start_date:datetime
company_create_date:datetime
company_status:enum('active','inactive')
在上面表中,可以用companiesCompany.company_name来获取公司名,不过这样是不支持搜索的。
想要支持搜索功能,需要在branches的index视图添加以下代码:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22

<?= GridView::widget([
'dataProvider' => $dataProvider ,
'filterModel' => $searchModel ,
'columns' => [
[ 'class' => 'yii\grid\SerialColumn' ],
//添加的代码开始
[
'label' => '公司名' ,
'attribute' => 'companies_company_id' ,
'value' => 'companiesCompany.company_name'
],
//添加的代码结束
'companiesCompany.company_name' ,
// 'branch_id',
// 'companies_company_id',
'branch_name' ,
'branch_address' ,
'branch_created_date' ,
// 'branch_status',
[ 'class' => 'yii\grid\ActionColumn' ],
],
]); ?>
|
然后修改SearchBranches.php
修改rules方法为:
1
2
3
4
5
6
7
|
public function rules()
{
return [
[[ 'branch_id' ], 'integer' ],
[[ 'branch_name' , 'branch_address' , 'branch_created_date' , 'branch_status' , 'companies_company_id' ], 'safe' ],
];
}
|
修改search方法:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
|
public function search( $params )
{
$query = Branches::find();
$dataProvider = new ActiveDataProvider([
'query' => $query ,
]);
$this ->load( $params );
if (! $this ->validate()) {
// uncomment the following line if you do not want to any records when validation fails
// $query->where('0=1');
return $dataProvider ;
}
// 添加下面这行代码
$query ->joinWith( 'companiesCompany' );
$query ->andFilterWhere([
'branch_id' => $this ->branch_id,
// 'companies_company_id' => $this->companies_company_id,
'branch_created_date' => $this ->branch_created_date,
]);
$query ->andFilterWhere([ 'like' , 'branch_name' , $this ->branch_name])
->andFilterWhere([ 'like' , 'branch_address' , $this ->branch_address])
->andFilterWhere([ 'like' , 'branch_status' , $this ->branch_status])
// 添加下面这行代码
->andFilterWhere([ 'like' , 'companies.company_name' , $this ->companies_company_id]);
return $dataProvider ;
