我正在研究Symfony中的Form（2.6）。用户可以选择免费产品，将其发送给用户。用户必须填写一些个人信息和他的地址（义务）。如果他想指定另一个传递地址，他会检查未映射到实体的复选框，并完成传递地址。现在，我想提交表单，并且只有在用户选中此复选框时才验证交付地址字段。如何才能做到这一点？
地址字段和传递地址字段使用映射到同一实体的相同表单类。我使用YAML文件作为我的约束。
（部分）validation.yml：
AppBundle\Entity\Address:
properties:
street:
- NotBlank: { message: "Please fill in your first name." }
- Length:
min: 3
max: 256
minMessage: "Please fill in your street name."
maxMessage: "Please fill in your street name."
number:
- NotBlank: { message: "Please fill in your house number." }
- Length:
min: 1
max: 10
minMessage: "Please fill in your house number."
maxMessage: "Please fill in your house number."
postCode:
- NotBlank: { message: "Please fill in your postal code." }
- Length:
min: 2
max: 10
minMessage: "Please fill in your postal code."
maxMessage: "Please fill in your postal code."
city:
- NotBlank: { message: "Please fill in your city." }
- Length:
min: 2
max: 256
minMessage: "Please fill in your city."
maxMessage: "Please fill in your city."
- Type:
type: alpha
message: "Please fill in your city."
country:
- NotBlank: { message: "Please select your country." }
- Country: ~
AppBundle\Entity\Product:
properties:
product:
- NotBlank: { message: "Please select your product." }
- Type:
type: integer
message: "Please select your product."
contact:
- Type:
type: AppBundle\Entity\Contact
- Valid: ~
deliveryAddress:
- Type:
type: AppBundle\Entity\Address
- Valid: ~
产品表格类别：
<?php
class ProductFormType extends AbstractType
{
/**
*
* @param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\Product'
));
}
/**
* Returns the name of this type.
*
* @return string The name of this type
*/
public function getName()
{
return 'product';
}
/**
*
* @param FormBuilderInterface $builder
* @param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('contact', new ContactFormType()); //CONTACTFORMTYPE also has an AddressFormType for the Address Fields
$builder->add('differentDeliveryAddress', 'checkbox', array( //delivery address is only specific for this Form
'label' => 'Different Shipping Address',
'required' => false,
'mapped' => false
));
$builder->add('deliveryAddress', new AddressFormType());
//specific
$builder->add('product', 'choice', array(
'choices' => array('a'=>'product x','b' => 'product y'),
'required' => true,
'invalid_message' => 'This field is required',
'label' => 'Your Free Product',
));
$builder->add('submit', 'button', array('label' => 'Submit'));
}
}
最后是My Controller中的getProductFormAction
public function getProductFormAction(Request $request)
{
$product = new Product();
$form = $this->get('form.factory')->create(new ProductFormType($product);
$form->handleRequest($request);
if($form->isValid()){
return new Response('Success'); //just to test
}
return $this->render(
'productForm.html.twig',
array(
'pageTitle' => 'Test',
'form' => $form->createView()
)
);
}
在此先感谢您的帮助！
这可以通过群体相对容易地实现。
首先，将组添加到您只想在特定场合（您的交货地址）字段中验证的字段。
street:
- NotBlank:
message: "Please fill in your first name."
groups: [delivery]
- Length:
min: 3
max: 256
minMessage: "Please fill in your street name."
maxMessage: "Please fill in your street name."
groups: [delivery]
现在这些验证都在特定的组中，除非明确告知，否则不会对它们进行验证。
现在，我们让表单确定何时验证该组。
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'validation_groups' => function (FormInterface $form) {
$data = $form->getData();
if ($data->differentDeliveryAddress()) {
return array('Default', 'delivery');
}
return array('Default');
},
));
}
此处，表单将始终验证“默认”组（未设置任何组的所有验证），并且还将在设置differentDeliveryAddress时验证“交付”组。
希望这可以帮助
Symfony文档中还有很多关于动态表单和实体/表单验证组的材料，它们应该指向正确的方向;例如：
这个用例似乎在SO上出现了很多。我建议你快速搜索一下，看看你能否发现类似的问题。
希望这可以帮助 ：）
