Zend 表单:调用未定义的方法 Zend\InputFilter\InputFilter::getFilterChain() [英] Zend Form : Call to undefined method Zend\InputFilter\InputFilter::getFilterChain()

问题描述

我正在尝试使用 Zend Form 上传图像.因为我们需要它来移动图像，所以我想添加一个过滤器来完成这项工作.但是我不能使用 getInputFilterChain()，我一直有这个致命错误:Call to undefined method Zend\InputFilter\InputFilter::getFilterChain().我在这里错过了什么?

I'm trying to upload an image with Zend Form. As we need it to move the image, I want to add a filter to do the job. But I can't use the getInputFilterChain(), I keep having this fatal error : Call to undefined method Zend\InputFilter\InputFilter::getFilterChain(). What am I missing here ?

我能够在 $prg 数组中获取文件信息.当我查看 https://framework.zend 时.com/manual/2.4/en/modules/zend.mvc.plugins.html，这里应该有这个方法，不是吗?

I'm able to get the file information in $prg array. And as I looked on https://framework.zend.com/manual/2.4/en/modules/zend.mvc.plugins.html, this method is supposed to exist here, no ?

如果我在我的 Form.php 文件中使用它，我会得到同样的错误.

And I get the same error if I use this in my Form.php file.

提前感谢您的时间！

我的控制器操作:

public function signinAction()
{
    $this->em = $this->getServiceLocator()->get('doctrine.entitymanager.orm_default');

    $form = new SignupForm($this->em);

    $form->getInputFilter()->getFilterChain()->attach(
        new Zend\Filter\File\RenameUpload(array(
            'target'    => './data/tmpuploads/file',
            'randomize' => true,
        ))
    );

    $model = new ViewModel(array("form" => $form));


    $url = $this->url()->fromRoute("signin");
    $prg = $this->fileprg($form, $url, true);

    if($prg instanceof \Zend\Http\PhpEnvironment\Response){       
        return $prg;
    }
    else if($prg === false){
       return $model;
    }

    //other stuff
    ...
}

推荐答案

您需要先从 InputFilter 中获取 Input 实例，然后才能获取过滤器-来自输入的链:

You need to get the Input instance from the InputFilter first and then you can get the filter-chain from the input:

$inputName = 'file'; // name of the input you want to work with
$input = $form->getInputFilter()->get($inputName);
$filterChain = $input->getFilterChain();
