Yii2 Gridview filtering not working

Question

Can you help me out with implementing filters to GridView in Yii2? Right now, my rendered table does not respond to my actions (search GET params are not added, nothing changes if I enter a query to a filter input). Here's my code: Controller:

$searchModel = new UserSearch();
        $dataprovider = $searchModel->search(\Yii::$app->request->get());
        return $this->render('index', [
            'dataProvider' => $dataprovider,
            'searchModel' => $searchModel
        ]);

Model (UserSearch.php):

public $fullname;

    public function rules()
    {
        return [
            [['fullname'], 'safe'],
        ];
    }

    public function search($params) {
        $query = StUsers::find();
        $dataProvider = new ActiveDataProvider([
           'query' => $query,
        ]);

        if(!($this->load($params) && $this->validate())) {
            return $dataProvider;
        }

        $query->andFilterWhere(['LIKE', 'fullname', $this->fullname]);
        return $dataProvider;
    }

View:

GridView::widget([
            'dataProvider' => $dataProvider,
            'filterModel' => $searchModel,
            'columns' => [
                'id',
                'fullname'
                ],
            ]);

Answer 1

I have the same problem when filtering in DataView. Perhaps the problem is in the client side. Check again if your jquery called twice on your page ( browser/source code ). May be your problem related with this also : jQuery(...).yiiGridView is not a function

Answer 2

There should be no need for a solution since 4 years have passed. But, problem is in next statement:

    if(!($this->load($params) && $this->validate())) {
        return $dataProvider;
    }

Change it to:

    $this->load($params);

    if (!$this->validate()) {
        return $dataProvider;
    }
