Symfony 3 FOSUserBundle 'Error: Cannot use object of type AppBundleEntityUser as array'

Question

我正在使用FOSUserBundle为我的Symfony3应用程序开发一个简单的控制器，以更新用户的电子邮件地址。

$user = $this->getUser();
$user->setEmail($email);

在第二行返回此错误。

Error: Cannot use object of type AppBundleEntityUser as array

考虑到我使用的是BaseUser类的方法，我显然没有将对象用作数组，所以我不知道它为什么会抛出这个错误。

控制器

/**
 * @Route("/portfolio/settings", name="portfolio_settings")
 */
public function settingsAction(Request $request)
{
    $user = $this->getUser();
    $em = $this->getDoctrine()->getManager();
    $email_form = $this->get('form.factory')->createNamedBuilder('change_email', FormType::class, $user)
        ->add('email', EmailType::class, array(
            'label' => 'E-Mail',
        ))
        ->add('save', SubmitType::class, array(
            'label' => 'Save'
        ))
        ->getForm();
    $password_form = $this->get('form.factory')->createNamedBuilder('change_password', FormType::class, $user)
        ->add('password', RepeatedType::class, [
            'type' => PasswordType::class,
            'invalid_message' => 'The password fields must match.',
            'options' => array('attr' => array('class' => 'password-field')),
            'required' => true,
            'first_options'  => array('label' => 'Password'),
            'second_options' => array('label' => 'Repeat Password'),
        ])
        ->add('save', SubmitType::class)
        ->getForm();
    $email_form->handleRequest($request);
    $password_form->handleRequest($request);
    if($email_form->isValid()){
        $data = $email_form->getData();
        $user->setEmail($data['email']);
        $em->persist($user);
        $this->addFlash(
            'success',
            'Your E-Mail address has been updated successfully'
        );
    }
    $em->flush();
    return $this->render('AppBundle:Portfolio:settings.html.twig', array(
        'email' => $email_form->createView(),
        'password' => $password_form->createView(),
    ));
}

Answer 1

展开第一个答案。

在Symfony中，当您使用实体创建表单时，表单方法getData()将返回最初传递给它的实体。因此，如果您已经拥有该实体（对象），则无需调用getData()。此外，handleRequest()已经根据您的表单更改了实体的值。除非在表单字段中您在选项中指定了'mapped' => false。

示例

/**
 * @Route("/portfolio/settings", name="portfolio_settings")
 */
public function settingsAction(Request $request)
{
    $user = $this->getUser();
    $em = $this->getDoctrine()->getManager();
    $email_form = $this->get('form.factory')->createNamedBuilder('change_email', FormType::class, $user)
        ->add('email', EmailType::class, array(
            'label' => 'E-Mail',
        ))
        ->add('save', SubmitType::class, array(
            'label' => 'Save'
        ))
        ->getForm();
    $email_form->handleRequest($request);
    if($email_form->isValid()){
        // Here we can persist the user, it's field for email have already been modified by ->handleRequest($request);
        // In fact if you var_dump($user->getEmail()) you'll see it's already your new value.
        $em->persist($user);
        $this->addFlash(
            'success',
            'Your E-Mail address has been updated successfully'
        );
        // I moved your flush here, because it's more appropriate to only flush when we've actually made a change.
        $em->flush();
    }
    return $this->render('AppBundle:Portfolio:settings.html.twig', array(
        'email' => $email_form->createView(),
        'password' => $password_form->createView(),
    ));
}

您可以在文档中找到所有这些以及更多信息http://symfony.com/doc/current/book/forms.html

最后$data = $form->getData()返回了您的用户实体，所以$data['email']给了您错误。

希望这能有所帮助。

Answer 2

$data = $email_form->getData();

$user->setEmail($data['email']);

Symfony\Component\Debug\Exception\FatalErrorException：错误：无法使用类型为AppBundle\Entity\User的对象作为数组

据说$data是您的实体用户。。。
