      return $this->renderPartial(‘myfiles‘,[‘model‘=>$model]);
  }
  public function actionGetfiles(){
    $model = new Uploadm();
    if (Yii::$app->request->isPost) {
      $model->imgFile = UploadedFile::getInstances($model, ‘imgFile‘);
      if ($model->upload()) {
        // 文件上传成功
        echo ‘上传成功‘;
      }
    }

    ];
  }
  public function upload()

   if ($this->validate()) { 
     foreach ($this->imgFile as $file) {
       $file->saveAs(‘uploads/‘ . $file->baseName . ‘.‘ . $file->extension);
