欢迎！
我已在表单中添加了一个字段
->add('languageLevel', ChoiceType::class, [
'choices' => [
Meme::LEVEL_BEGINNER => Meme::LEVEL_BEGINNER,
Meme::LEVEL_INTERMEDIATE => Meme::LEVEL_INTERMEDIATE,
Meme::LEVEL_ADVANCED => Meme::LEVEL_ADVANCED,
Meme::LEVEL_EXPERT => Meme::LEVEL_EXPERT
]
])
此表格可以保存实体＆Meme＆＃39;具有相同的属性
/**
* @var string
* @ORM\Column(name="language_level", type="string", length=20)
*/
private $languageLevel;
prod.log给了我这个：

好的，在开发服务器上遇到了同样的问题（刚从apache配置中的app_dev.php切换到app.php并添加了app / autoload.php）
/**
* @Route("/meme/add", name="meme_add")
* @param Request $request
* @return \Symfony\Component\HttpFoundation\Response
* @internal param Request $request
*/
public function addAction(Request $request)
{
$user = $this->getUser();
if (!$user || !$user->hasRole('ROLE_MEME_ADD_AWAITING')) {
$this->addFlash('notice', 'You need to login');
return $this->redirectToRoute('fos_user_security_login');
}
if (!$this->get('security.authorization_checker')->isGranted('IS_AUTHENTICATED_FULLY')) {
throw $this->createAccessDeniedException();
}
$meme = new Meme();
$form = $this->createForm(MemeAddType::class, $meme);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid() ) {
if ($user->hasRole('ROLE_MEME_ADD_AWAITING')) {
$meme->setPublishingStatus('awaiting-publishing');
} else if ($this->getUser()->hasRole('ROLE_MEME_ADD_MAIN')) {
$meme->setPublishingStatus('published');
}
$em = $this->getDoctrine()->getManager();
$em->persist($meme);
$em->flush();
}
return $this->render(
'@App/memes/add.html.twig',
[
'memeAddForm' => $form->createView()
]
);
}

在formType

use AppBundle\Entity\Language;
use AppBundle\Entity\Meme;

实际上，发生的事情是我有
'data' => 2
在textOneLang表单元素中，因此当它被赋予spl_object_hash（）函数时它失败了，它只接受对象而不是整数。没有使用数据转换器。但是这个'数据'参数不应该首先存在，不知道它是如何结束的。可能在尝试调试时。经验教训，找出所有选项，并将你在spl_object_hash（）中作为参数转储。
app_dev.php和app.php之间的区别与它没有任何关系。它可能在app_dev.php中以某种方式缓存并处理了一些旧版本。
