My View




<?php $form = ActiveForm::begin([

        'id' => 'Items',

        'enableClientValidation' => false,

        'errorSummaryCssClass' => 'error-summary alert alert-error',

        'options' => ['enctype' => 'multipart/form-data', 'accept' => 'image/*']

    ]);

    ?>

    <?php echo $form->errorSummary($model); ?>


<?php echo FileInput::widget([

        'name' => 'photo_image[]',

        'model' => $photos,

        'options'=>[

            'multiple'=>true

            'overwriteInitial'=>false,

        ],

    ]);

    ?>

<?php ActiveForm::end(); ?>



My Controller




public function actionFileUpload($id){

        $model = new Photo();

            dd($_POST, $_FILES, $photos);


        }

        return false;

    }


//            dd($_POST, $_FILES, $photos);




My Model




class Photo extends BasePhoto

{

    const INSERT = 'insert';

    const UPDATE = 'update';


    public function scenarios()

    {

        $scenarios = parent::scenarios();
