自定义表单只接受特定的电子邮件地址FOSUserBundle 2.0 / Symfony3

标签: symfony fosuserbundle event-listener

我尝试学习使用Symfony 3.1.10创建一个网站。为了帮助我创建登录/注册项目,我决定使用捆绑包" FOSUserBundle 2.0"。所以现在我创建一个自定义表单(我按名称字段更改了用户名字段)。对于我的项目,我试图允许只注册具有特定电子邮件地址的用户。因此经过一些研究,他们解释了创建自定义行为,FOSUserbundle创建了事件。所以,当我有REGISTRATION_SUCCESS时,我会创建自定义事件监听器,如下所示。

class CheckEmailBefore implements EventSubscriberInterface {

private $router;
private $request;

public function __construct(RouterInterface $router,Request $request)
{
    $this->router = $router;
    $this->request = $request;
}

public static function getSubscribedEvents() {
    return [
        FOSUserEvents::REGISTRATION_SUCCESS => 'onCheck'
    ];
}


/**
 * @param FormEvent $event
 *
 */
public function onCheck(FormEvent $event){

    $user = $event->getForm()->getData();
    $email = $user->getEmailCanonical();

    $format = explode("@",$email);

    if((strcmp($format[1] , "truc.com")===0) || (strcmp($format[1] , "chose.com") === 0)){

        $url = $this->router->generate('list');
        $response = new RedirectResponse($url);
        $event->setResponse($response);


    }else{
        $event->getForm()->addError(new FormError("Enter a mail address with valid format"), 1);
        var_dump($event->getForm()->getErrors());

        die("Address is not valid");
    }






}
}

我的问题是,一旦我添加错误,我不知道如何在我的表单上显示它,就像捆绑包已经创建的错误一样。

提前致谢。

我不会为此使用Event Dispatcher组件,我只是简单地创建一个自定义验证约束。这是the link to the docs

您可以创建一个约束,以检查您的用户是否在其电子邮件中包含特定域。如果约束未通过,则验证将失败,从而导致注册过程失败,从而为您提供正确的错误信息。

文档解释得非常好,但如果您需要实施方面的帮助,请告诉我,我可以更新我的答案。

class RegistrationForm extends OtherForm
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        parent::buildForm($builder, $options);
        $builder
            ->add('firstName', TextType::class, [
                'required' => true,
                'constraints' => [
                    new NotBlank(),
                    new Length(['min' => 2, 'max' => 20]),
                ]
            ])
            ->add('lastName', TextType::class, [
                'required' => true,
                'constraints' => [
                    new NotBlank(),
                    new Length(['min' => 2, 'max' => 20]),
                ]
            ])
            ->add('secondLastName', TextType::class, [
                'required' => true,
                'constraints' => [
                    new NotBlank(),
                    new Length(['min' => 2, 'max' => 20]),
                ]
            ])
            ->add('email', TextType::class, [
                'required' => true,
                'constraints' => [
                    new NotBlank(),
                    new CustomConstraint(),
                    new Length(['min' => 2, 'max' => 20]),
                ]
            ])
        ;
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => User::class,
            'csrf_protection' => false,
            'allow_extra_fields' => true,
        ]);
    }
