在yii2中对CGridView和CArrayDataProvider使用筛选器

use yii\base\Model;

class SearchModel extends Model
{
    public $field1;
    public $field2;
    
    public function rules()
    {
        return [
            [['field1', 'field2'], 'safe'],
        ];
    }
}

public function actionIndex()
{
    $searchModel = new SearchModel();
    $dataProvider = new CArrayDataProvider([
        'allModels' => $data,
        'sort' => [
            'attributes' => ['field1', 'field2'],
        ],
        'pagination' => [
            'pageSize' => 10,
        ],
    ]);
    
    return $this->render('index', [
        'searchModel' => $searchModel,
        'dataProvider' => $dataProvider,
    ]);
}

<?= GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [
        'field1',
        'field2',
        // other columns
    ],
]); ?>

public function search($params)
{
    $query = YourModel::find();
    
    $dataProvider = new ActiveDataProvider([
        'query' => $query,
        'pagination' => [
            'pageSize' => 10,
        ],
    ]);
    
    $this->load($params);
    
    if (!$this->validate()) {
        return $dataProvider;
    }
    
    $query->andFilterWhere(['like', 'field1', $this->field1])
        ->andFilterWhere(['like', 'field2', $this->field2]);
    
    return $dataProvider;
}
