我的網格視圖過濾器沒有過濾類別,我已經給nesserray的地方category_id,但它沒有根據他們的category_id過濾我的帖子,請幫助我。 這裏是我的源代碼:
後 - >的index.phpyii2網格過濾不工作
<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'title',
[
'attribute'=>'category_id',
'value'=>function($model) {
return $model->category->name;
},
'filter'=>$category
],
[
'attribute'=>'user_id',
'value'=>function($model) {
return $model->user->fullname;
},
'filter'=>$user,
'label'=>'user'
],
'category.name',
'user.fullname',
// 'user_id',
// 'description',
// 'content:html',
'count_view',
'status',
'created_at',
['class' => 'yii\grid\ActionColumn'],
],
]); ?>
,這裏是模型/ postSearch.php
<?php
namespace app\models\search;
use Yii;
use yii\base\Model;
use yii\data\ActiveDataProvider;
use app\models\post;
/**
* PostSearch represents the model behind the search form about `app\models\post`.
*/
class PostSearch extends post
{
/**
* @inheritdoc
*/
public function rules()
{
return [
[['id', 'user_id','category_id', 'count_view'], 'integer'],
[['title', 'description', 'content', 'status', 'created_at'], 'safe'],
];
}
/**
* @inheritdoc
*/
public function scenarios()
{
// bypass scenarios() implementation in the parent class
return Model::scenarios();
}
/**
* Creates data provider instance with search query applied
*
* @param array $params
*
* @return ActiveDataProvider
*/
public function search($params)
{
$query = post::find();
// add conditions that should always apply here
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
$this->load($params);
if (!$this->validate()) {
// uncomment the following line if you do not want to return any records when validation fails
// $query->where('0=1');
return $dataProvider;
}
// grid filtering conditions
$query->andFilterWhere([
'id' => $this->id,
'category_id' => $this->category_id,
'user_id' => $this->user_id,
'count_view' => $this->count_view,
'created_at' => $this->created_at,
]);
$query->andFilterWhere(['like', 'title', $this->title])
->andFilterWhere(['like', 'description', $this->description])
->andFilterWhere(['like', 'content', $this->content])
->andFilterWhere(['like', 'status', $this->status]);
return $dataProvider;
}
}
