Symfony检查表单验证中两个字段中的至少一个是否不为空 [英] Symfony Check if at least one of two fields isn't empty on form validation
问题描述
我已经想了好一阵子了,但仍然找不到解决我问题的方法。使用Symfony 4表单和约束条件,我无法设置检查方式,以使提交包含子表单的表单时两个字段中的至少一个不能为空。
<我有一个预订实体,其中包含一个访客实体,该访客实体具有phoneNumber属性和email属性。我希望能够创建一个具有访客 CollectionType的预订(允许从BookingType表单添加访问者)。
我的BookingType形式(略微简化):
class BookingType扩展AbstractType
{
专用$ router;
私人$ translator;
公共功能__construct(UrlGeneratorInterface $ router,TranslatorInterface $ translator)
{
$ this-> router = $ router;
$ this-> translator = $ translator;
}
公共功能buildForm(FormBuilderInterface $ builder,array $ options)
{
$ builder
-> add('bookableTimeSlot',EntityType :: class,[
'label'=>'entity.booking.bookable-time-slot',
'class'=> BookableTimeSlot :: class,
'choice_label'= >函数($ bookableTimeSlot){
return $ bookableTimeSlot-> getStartDateTime()-> format('dmY h\hi');
}
])
-> add('visitors',CollectionType :: class,[
'entry_type'=> VisitorType :: class,
'label'=>'entity.booking.visitors',
'allow_add'=> true,
'by_reference'=> false,
'entry_options'=> ['label'=> false]
])
;
}
公共功能configureOptions(OptionsResolver $ resolver)
{
$ resolver-> setDefaults([
'data_class'=>预订: :class,
'user'=> User :: class,
]);
}
}
我的访客实体(有点简化):
<?php
命名空间App\Entity;
使用Doctrine\ORM\Mapping作为ORM;
使用Symfony\Component\Validator\Constraints作为断言;
使用Symfony\组件\Validator\Context\ExecutionContextInterface;
/ **
* @ ORM\Entity(repositoryClass = App\Repository\VisitorRepository)
* /
类访问者
{
/ **
* @ ORM\Id()
* @ ORM\GeneratedValue()
* @ ORM\Column(type = integer)
* /
私人$ id;
/ **
* @ ORM\Column(type = string,length = 255)
* /
private $ firstName;
/ **
* @ ORM\Column(type = string,length = 255)
* /
private $ lastName;
/ **
* @ ORM\Column(type = string,length = 45,nullable = true)
* /
私人电话;
/ **
* @ ORM\ManyToOne(targetEntity = App\Entity\Booking,inversedBy = visitors)
* @ ORM\JoinColumn (nullable = false)
* /
私人$ booking;
/ **
* @ ORM\Column(type = string,length = 255,nullable = true)
* /
私人$ email;
公共函数getId():?int
{
return $ this-> id;
}
公共函数getFirstName():?string
{
return $ this-> firstName;
}
公共函数setFirstName(string $ firstName):self
{
$ this-> firstName = $ firstName;
返回$ this;
}
公共函数getLastName():?string
{
return $ this-> lastName;
}
公共函数setLastName(string $ lastName):self
{
$ this-> lastName = $ lastName;
返回$ this;
}
公共功能getPhone():? string
{
return $ this-> phone;
}
公共功能setPhone(string $ phone):自我
{
$ this-> phone = $ phone;
返回$ this;
}
公共函数getBooking():?预订
{
return $ this->预订;
}
公共功能setBooking(?Booking $ booking):自我
{
$ this-> booking = $ booking;
返回$ this;
}
公共函数getEmail():?string
{
return $ this-> email;
}
公共功能setEmail(?string $ email):self
{
$ this-> email = $ email;
返回$ this;
}
}
最后确定我的VisitorType表单(略有简化):
class VisitorType扩展AbstractType
{
public function buildForm(FormBuilderInterface $ builder,array $ options)
{
$ builder
-> add('firstName',TextType :: class,[
'label'= >>'entity.visitor .first-name',
])
-> add('lastName',TextType :: class,[
'label'=>'entity.visitor.last-name' ,
])
-> add('phone',TextType :: class,[
'label'=>'entity.visitor.phone-number',
'required'=> false,
])
-> add('email',TextType :: class,[
'label'= >>'entity.visitor.email' ,
'required'=>否,
'constraints'= >> [
新的Email()
]
])
;
}
公共函数configureOptions(OptionsResolver $ resolver)
{
$ resolver-> setDefaults([
'data_class'=> :class,
]);
}
}
我尝试将Expression约束添加到电子邮件和电话字段,看起来像这样:
new Expression([
'expression'=>'this .getPhone()== null&& this.getEmail()== null'
])
也尝试将约束直接添加到实体,但对我而言似乎没有任何正常工作。
任何帮助将不胜感激。
更新
我没有指定这个,但是我的问题来自于我想从另一个将VisitorType添加为CollectionType的表单中验证VisitorType表单的事实。
尝试回调
/ **
* @ Assert\Callback
* /
public function validate(ExecutionContextInterface $ context,$ payload)
{
if (null === $ this-> getEmail()&& null === $ this-> getPhone())
$ context-> buildViolation('您的消息在这里。')
-> atPath('email')
-> addViolation();
//如果您喜欢
},则可以添加其他如果,则
I've been turning this around in my head for quite a while now and still wasn't able to find a solution to my problem. Using Symfony 4 forms and constraints I'm unable to setup a check to say that at least one of two fields must not be empty when submitting form that contains a sub-form.
I have a Booking entity which contains a Visitor entity which has a phoneNumber property and a email property. I'd like to be able to create a Booking which has a "visitors" CollectionType (where I'm allowed to add visitors from the BookingType form).
My BookingType form (a bit simplified):
class BookingType extends AbstractType
{
private $router;
private $translator;
public function __construct(UrlGeneratorInterface $router, TranslatorInterface $translator)
{
$this->router = $router;
$this->translator = $translator;
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('bookableTimeSlot', EntityType::class, [
'label' => 'entity.booking.bookable-time-slot',
'class' => BookableTimeSlot::class,
'choice_label' => function ($bookableTimeSlot) {
return $bookableTimeSlot->getStartDateTime()->format('d.m.Y h\hi');
}
])
->add('visitors', CollectionType::class, [
'entry_type' => VisitorType::class,
'label' => 'entity.booking.visitors',
'allow_add' => true,
'by_reference' => false,
'entry_options' => ['label' => false]
])
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => Booking::class,
'user' => User::class,
]);
}
}
My Visitor entity (a bit simplified):
<?php
namespace App\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\Validator\Context\ExecutionContextInterface;
/**
* @ORM\Entity(repositoryClass="App\Repository\VisitorRepository")
*/
class Visitor
{
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @ORM\Column(type="string", length=255)
*/
private $firstName;
/**
* @ORM\Column(type="string", length=255)
*/
private $lastName;
/**
* @ORM\Column(type="string", length=45, nullable=true)
*/
private $phone;
/**
* @ORM\ManyToOne(targetEntity="App\Entity\Booking", inversedBy="visitors")
* @ORM\JoinColumn(nullable=false)
*/
private $booking;
/**
* @ORM\Column(type="string", length=255, nullable=true)
*/
private $email;
public function getId(): ?int
{
return $this->id;
}
public function getFirstName(): ?string
{
return $this->firstName;
}
public function setFirstName(string $firstName): self
{
$this->firstName = $firstName;
return $this;
}
public function getLastName(): ?string
{
return $this->lastName;
}
public function setLastName(string $lastName): self
{
$this->lastName = $lastName;
return $this;
}
public function getPhone(): ?string
{
return $this->phone;
}
public function setPhone(string $phone): self
{
$this->phone = $phone;
return $this;
}
public function getBooking(): ?Booking
{
return $this->booking;
}
public function setBooking(?Booking $booking): self
{
$this->booking = $booking;
return $this;
}
public function getEmail(): ?string
{
return $this->email;
}
public function setEmail(?string $email): self
{
$this->email = $email;
return $this;
}
}
And finaly my VisitorType form (a bit simplified):
class VisitorType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('firstName', TextType::class, [
'label' => 'entity.visitor.first-name',
])
->add('lastName', TextType::class, [
'label' => 'entity.visitor.last-name',
])
->add('phone', TextType::class, [
'label' => 'entity.visitor.phone-number',
'required' => false,
])
->add('email', TextType::class, [
'label' => 'entity.visitor.email',
'required' => false,
'constraints' => [
new Email()
]
])
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => Visitor::class,
]);
}
}
I've tried to add an Expression constraint to the email and phone field which looked something like this:
new Expression([
'expression' => 'this.getPhone() == null && this.getEmail() == null'
])
Also tried to add constraint directly to the entity, but nothing seems to work correctly for me.
Any help would be greatly appreciated.
UPDATE I haven't specified this, but my problem comes from the fact that I would like to validate the VisitorType form from another form which adds the VisitorType as a CollectionType.
try with callback
/**
* @Assert\Callback
*/
public function validate(ExecutionContextInterface $context, $payload)
{
if (null === $this->getEmail() && null === $this->getPhone())
$context->buildViolation('Your message here.')
->atPath('email')
->addViolation();
// you can add onther "if" if you like
}
