Symfony仅阅读复选框检查

我正在寻找一种禁用文本输入验证的方法，并在检查框时阅读文本类型？

$formBuilder
            ->add('text',      TextType::class,array(
            'required' => true,
            'constraints' => array(
                new NotBlank()
            )))
            ->add('box',      CheckboxType::class, array(
                'mapped' => false,
                'label' => 'Box'
            ))

    ;

I'm looking for a way to disable text input validation and readOnly the TextType if the box is checked?

$formBuilder
            ->add('text',      TextType::class,array(
            'required' => true,
            'constraints' => array(
                new NotBlank()
            )))
            ->add('box',      CheckboxType::class, array(
                'mapped' => false,
                'label' => 'Box'
            ))

    ;

您需要将EventListener添加到您的FormBuilder，并基于输入数据添加约束。阅读有关动态形式修改的更多信息在这里。

未经测试，但也许是这样的：

$formBuilder->add('text', ...);
$formBuilder->add('box', ...);

$formBuilder->addEventListener(FormEvents::PRE_SET_DATA, function (FormEvent $event) {
   $data = $event->getData();
   $form = $event->getForm();

   if (isset($data["box"])) {  // Or use something like $data->getBox() if you are using objects
      $formBuilder->add('text', ...); // Replace field without constraints
   }
   
});

请记住，这只会进行服务器端验证，而不是前端。

You'll need to add an eventListener to your formBuilder and add constraints based on input data. Read more about dynamic form modification here.

Not tested but maybe something like this:

$formBuilder->add('text', ...);
$formBuilder->add('box', ...);

$formBuilder->addEventListener(FormEvents::PRE_SET_DATA, function (FormEvent $event) {
   $data = $event->getData();
   $form = $event->getForm();

   if (isset($data["box"])) {  // Or use something like $data->getBox() if you are using objects
      $formBuilder->add('text', ...); // Replace field without constraints
   }
   
});

Keep in mind that this will only do server side validation, not frontend.
