Question

我想在表单构建中将'strict' => true添加到电子邮件验证输入中 https://symfony.com/doc/3.3/reference/constraints/Email.html#strict

为什么呢？因为普通电子邮件验证允许无效的电子邮件。 test@test通过了！

我试过，但我收到错误(The option "strict" does not exist. Defined options are: "action", "allow_extra_fields", "attr", ... )

这样的代码：

public function buildForm(FormBuilderInterface $builder, array $options) :void
{
     $builder
     ->add('name', TextType::class, [ 'label' => 'Name' ])
     ->add('email', EmailType::class, [
           'label' => 'Email', 
           'strict' => true ]  <<<<< not work
     )
     ->add('subject', ChoiceType::class, [ 'label' => 'Subject',
     ...

Answer 1

尝试注册以下验证限制：

$builder
     ->add('name', TextType::class, [ 'label' => 'Name' ])
     ->add('email', EmailType::class, [
           'label' => 'Email', 
           'constraints' => array(
               new Email(array('strict'=>true)),
            )
       )

Answer 2

除了将'strict' => true添加到Email约束选项之外，Symfony框架配置中还存在一个设置，以默认情况下为所有Email约束启用它。参见strict_email configuration in the Symfony docs v3.4

对于Symfony> = 4.1，配置选项strict_email已弃用so use email_validation_mode instead

symfony 3使用'strict'=＆gt;在电子邮件验证字段中为true
