CakePHP：对成员函数的调用

我在CakePHP中开发了一个帮助程序来上传文件，但是当我在操作中使用它时，它返回了一个错误。 我知道这个错误的意思，我试图用

public$helpers=array（'Session'，'File'，'Html'）调用helper在控制器中，但发生相同的情况。我不知道该怎么办。
错误：

FileHelper.php：
        $info['name'] = $File['name'];
        $info['tmp'] = $File['tmp_name'];
        $info['ext']['mime'] = $File['type'];
        $info['ext']['ext'] = $typeq[1];
        $info['size']['b'] = $File['size'];
        $info['size']['kb'] = $File['size'] / 1024;
        $info['size']['mb'] = $info['size']['kb'] / 1024;
        $info['error'] = $File['error'];
        $info['hashed_name'] = $nname;
        if($getHashed):
            return $info['hashed_name'];
        else:
            return $info;
        endif;
    }else{
        return "A file was not specified.";
    }
}

显示错误的行是：

$this->request->data['MainSlider']['slide'] = $this->File->info($this->data['MainSlider']['slide_file'], true);

重要的一点是，您希望使用帮助程序作为组件。Helper只能在视图中使用，您可以随意修改并强制使用它，但必须将上载逻辑移动到行为中。处理上传不是视图层的责任

可从控制器访问

，例如文件上载：

控制器视图组件的帮助器。
对不起，您的实际问题是什么？帮助器是处理文件上载最错误的位置之一。。。这是模型层的任务。还有一些插件可以很好地处理文件上传和文件管理@戴维戴尔：我能做些什么来解决这个问题problem@GabrielOak将实际的错误消息添加到您的问题中如何。。。？作为开发人员，您应该知道“不工作”和不提供错误消息或调试数据是毫无意义的。但是，帮助程序完全不符合您的要求。@burzum

文件上载应在模型层处理，这意味着一种行为。不是一个组件。是的，我同意你的观点。你是对的。更好的地方是行为。因为它是数据处理逻辑，所以应该将它移到那里。组件仅用于支持控制器。
$this->request->data['MainSlider']['slide'] = $this->File->info($this->data['MainSlider']['slide_file'], true);
