我正在尝试使用symfony上传文件。但是当我向控制器发送数据公式时，我有一个错误。变量文件为空，函数移动文件无效。
代码实体（par uplaod）：

code formType（内容变量文件）：

功能帖子（持久对象）：
public function post(array $parameters, bool $submitted = true, array $options = [])
{
/** @var Recruiter $recruiter */
$recruiter = $this->formHandler->handle(
$this->userManager->createRecruiter(),
$parameters,
Request::METHOD_POST,
$submitted,
$options
);
if (false === $submitted) {
return $recruiter;
}
$recruiter->submit($parameters);
if ($recruiter->isSubmitted() && $recruiter->isValid()) {
$recruiter->getData()->setCompany($recruiter->getData()->getCompany());
$recruiter->getData()->getCompany()->upload();
$this->em->persist($recruiter->getData());
$this->em->flush();
$event = new FormEvent($recruiter, $this->request);
$this->eventDispatcher->dispatch(FOSUserEvents::REGISTRATION_SUCCESS, $event);
return $recruiter->getData();
}
return $recruiter;
}
代码控制器：
<?php
namespace AppBundle\Controller\Recruiter;
use FOS\UserBundle\Controller\RegistrationController as BaseController;
use FOS\UserBundle\Event\GetResponseUserEvent;

use Symfony\Component\HttpFoundation\Response;

{
/**

*/
public function registerAction(Request $request)
{
try {
$user = new UserManagerr();
$dispatcher = $this->get('event_dispatcher');
$user = $user->createRecruiter();
$event = new GetResponseUserEvent($user, $request);
$dispatcher->dispatch(FOSUserEvents::REGISTRATION_INITIALIZE, $event);
if (null !== $event->getResponse()) {
return $event->getResponse();
}
$recruiter = $this->getHandler()->post($request->request->all(), $request->isMethod(Request::METHOD_POST));
if ($recruiter instanceof Recruiter) {
$url = $this->generateUrl('fos_user_registration_check_email');
$response = new RedirectResponse($url);
return $response;
}
} catch (InvalidFormException $e) {
$event = new FormEvent($form, $request);
$dispatcher->dispatch(FOSUserEvents::REGISTRATION_FAILURE, $event);
return [
'form' => $e->getForm()->createView(),
'edit' => false,
'event' => $event->getResponse(),
];
}
return ['form' => $recruiter->createView()];
}
/**
* @return RecruiterHandler
*/
public function getHandler()
{
return $this->get(RecruiterHandler::class);
}
}
我使用form imbriqu（其他形式的表单），但是当我发送表单时，我有来自object的所有变量，但变量文件有null，函数move不起作用。
如何解决此错误？ 提前感谢您的帮助。

更改此
public function post(array $parameters, bool $submitted = true, array $options = [])
对于
public function post(Request $request, bool $submitted = true, array $options = [])
[...]
$recruiter->submit($request);
[...]

Your issue is probably in the for tag, which you should declare it like:
{{ form_start(form, {'method': 'post', 'action': '', 'attr': {'class': '', 'novalidate': 'novalidate' }}) }}
