我想在我的cakephp 3.0应用程序中上传图像.但我收到错误消息:

Notice (8): Undefined index: Images [APP/Controller/ImagesController.php, line 55]

在cakePHP 3.0中是否已经有一些上传文件(一次多个文件)的例子？因为我只能找到cakePHP 2.x的例子!

我想我需要在ImagesTable.php中添加自定义验证方法？但我无法让它发挥作用.

ImagesTable

public function initialize(array $config) {

       ->add('processImageUpload', 'custom', [
          'rule' => 'processImageUpload'
       ])
}

public function processImageUpload($check = array()) {
    if(!is_uploaded_file($check['image_path']['tmp_name'])){
       return FALSE;
    }
    if (!move_uploaded_file($check['image_path']['tmp_name'], WWW_ROOT . 'img' . DS . 'images' . DS . $check['image_path']['name'])){
        return FALSE;
    }
    $this->data[$this->alias]['image_path'] = 'images' . DS . $check['image_path']['name'];
    return TRUE;
}

ImagesController

public function add()
    {
        $image = $this->Images->newEntity();
        if ($this->request->is('post')) {
            $image …
