Catchable致命错误：参数1传递给？ Symfony2.1 [英] Catchable Fatal Error: Argument 1 passed to ? Symfony2.1

问题描述

我被此错误停止：

可捕获致命错误：参数1传递给
Joker\CoreBundle\ Entity \Incidentfile :: setFile（）必须是
的实例Symfony \Component\HttpFoundation\File\UploadedFile，字符串给定，
在
中调用Applications / MAMP / htdocs / joker-repo / vendor / symfony / symfony / src / Symfony / Component / Form / Util / PropertyPath.php
在538行，并在
中定义Applications / MAMP / htdocs / joker-repo / src / Joker / CoreBundle / Entity / Incidentfile.php
line 157

Catchable Fatal Error: Argument 1 passed to Joker\CoreBundle\Entity\Incidentfile::setFile() must be an instance of Symfony\Component\HttpFoundation\File\UploadedFile, string given, called in /Applications/MAMP/htdocs/joker-repo/vendor/symfony/symfony/src/Symfony/Component/Form/Util/PropertyPath.php on line 538 and defined in /Applications/MAMP/htdocs/joker-repo/src/Joker/CoreBundle/Entity/Incidentfile.php line 157

在我的实体中，我有setter和getter for File 。我使用此方法进行文件上传：此

In my entity I have setters and getters for File. I used this method to make file Upload: THIS

文件夹upload_images有权限问题，但我解决了一切正常，但现在出了问题。

And there was permission problem for folder upload_images but after i solved it everything worked fine but now something went wrong.

这是我的控制器：

public function TestAction(Request $request){
        $incfileRepo = new Incidentfile();
        $formfile = $this->createForm(new IncfileType(), $incfileRepo);


        if ($request->isMethod('POST')) {
            $formfile->bind($request);

            if ($formfile->isValid()) {


                $em = $this->getDoctrine()->getManager();

                $em->persist($incfileRepo);
                $em->flush();

                return $this->redirect($this->generateUrl('incident_show'));
            }
        }

        $spotEntity = $this->getCurrentSpot();
        $sentryEntity = $this->getCurrentSentry();
        $messagesCollection = $this->getDoctrine()->getRepository('JokerCoreBundle:Message')->findBy(array(
            'spot'  =>  $spotEntity,
            'sentry'    =>  $sentryEntity
        ), array(
            'sent_date' =>  'DESC'
        ));

        return $this->render('JokerAdminBundle:incidents:addfullform.html.twig', $this->getViewConstants(array(
            'formfile'=>$formfile->createView(),
            'spot'  =>  $spotEntity,
            'sentry'    =>  $sentryEntity,
            'messagesCollection'    =>  $messagesCollection,
        )));


    }

Form in twig:

 <form action="" method="post">
                    {{ form_rest(formfile) }}

                    <div class="singleTableForm">
                        <input style="float: left; margin-left: 338px; " type="submit" name="" class="button" value="Add" />
                    </div>
                </form>

推荐答案

我发现什么错了。问题：

I found out what was wrong.. In twig was problem:

<form action="" method="post" {{ form_enctype(formfile) }}>

只需添加 ** {{form_enctype（formfile）}} **
