GridView filter model in Yii2 - php

Question

I have a gridview with a dataprovider which has joined two tables as query:
$applicationDataProvider = new ActiveDataProvider([
'query' => Application::find()->with('applicantInfo')
->where(['job_posting_id' => $jobPosting->id,
'deleted_flag' => 0])->orderBy('created_at desc'),
'pagination' => [
'pageSize' => 5
]
]);
and here is my GridView:
<?= GridView::widget([
'dataProvider' => $applicationDataProvider,
'filterModel'=>$searchModel,
'columns' => [
'id',
[
'class' => yii\grid\DataColumn::className(),
'headerOptions' => ['style' => 'color:#337ab7'],
'header' => 'სახელი',
'label'=>'name',
'value' => function ($data) {
return $data->applicantInfo->first_name . ' ' . $data->applicantInfo->last_name;
}
],
'applicantInfo.email',
'applicantInfo.phone',
'created_at:date',
[
'class' => 'yii\grid\ActionColumn',
'headerOptions' => ['style' => 'color:#337ab7'],
'template' => '{view}',
'buttons' => [
'view' => function ($url, $model) {
return Html::a('<span class="glyphicon glyphicon-eye-open"></span>', $url, [
'title' => Yii::t('app', 'გახსნა'),
]);
}
],
'urlCreator' => function ($action, $model, $key, $index) {
if ($action === 'view') {
$url = '/app-info/?id=' . $model->id;
return $url;
}
}
...
in a search model I have email field only because I want to gridview has just only email search field.
class ApplicationSearch extends Application
{
public function rules()
{
return [
[['email'], 'safe'],
];
}
but here is not drawn search field for email, how can I fix it?

Answer 1

You need to add email attribute to ApplicationSearch to store value from filter:
class ApplicationSearch extends Application {
public $email;
public function rules() {
return [
[['email'], 'safe'],
];
}
}
Use this attribute for filtering:
$applicationDataProvider = new ActiveDataProvider([
'query' => Application::find()->with('applicantInfo')
->where(['job_posting_id' => $jobPosting->id, 'deleted_flag' => 0])
->andFilterWhere(['like', 'applicantInfo.email', $this->email])
->orderBy('created_at desc'),
'pagination' => [
'pageSize' => 5
]
]);
And use value from relation in grid:
// ...
[
'attribute' => 'email',
'value' => function ($data) {
return $data->applicantInfo->email;
},
],
'applicantInfo.phone',
// ...
