Answer 1

Try this , i hope this will help you, instead of this kartik\grid\CheckboxColumn use this yii\grid\CheckboxColumn

Step 1: create a button for multiple delete in index.php

Step 2: In your index.php(same page) use this javascript

registerJs(' 

    $(document).ready(function(){
    $(\'#MyButton\').click(function(){

        var HotId = $(\'#w4\').yiiGridView(\'getSelectedRows\');
          $.ajax({
            type: \'POST\',
            url : \'index.php?r=hotel/multiple-delete\',
            data : {row_id: HotId},
            success : function() {
              $(this).closest(\'tr\').remove(); //or whatever html you use for displaying rows
            }
        });

    });
    });', \yii\web\View::POS_READY);

?>

this jquery is used to get the value(id) of selected row

Step 3: in controller of hotel (HotelController.php) create a action for multiple-delete

public function actionMultipleDelete()
    {
        $pk = Yii::$app->request->post('row_id');

        foreach ($pk as $key => $value) 
        {
            $sql = "DELETE FROM hotel WHERE hotel_id = $value";
            $query = Yii::$app->db->createCommand($sql)->execute();
        }

        return $this->redirect(['index']);

    }

Try this surely this will help you...
