我已经阅读了this。但这没有用。我添加了'required' => false
但没有任何反应。
<?php
namespace BN\Bundle\XxBundle\Form\Type;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver;
use FOS\UserBundle\Form\Type\RegistrationFormType as BaseType;
class PersonStudentRegistrationType extends BaseType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
parent::buildForm($builder, $options);
$builder
->add(
...
...
)
->add(
'adresses',
'collection',
array(
'type' => new AdresseType(),
'allow_add' => true,
'by_reference' => false,
'required' => false
)
)
我确保实体中的Adresse可以为空:
<?php
namespace BN\Bundle\XxBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Adresse
*
* @ORM\Table(name="adresse")
* @ORM\Entity
* @ORM\HasLifecycleCallbacks()
*/
class Adresse
{
/**
* @var integer
*
* @ORM\Column(name="id", type="bigint", nullable=false)
* @ORM\Id
* @ORM\GeneratedValue(strategy="IDENTITY")
*/
private $id;
//...
// some other code...
//...
/**
* @var string
*
* @ORM\Column(name="adresse1", type="string", length=250, nullable=true)
*/
private $adresse1;
/**
* @var string
*
* @ORM\Column(name="adresse2", type="string", length=250, nullable=true)
*/
private $adresse2;
我错过了什么?注意:我已按照this official tutoriel制作动态字段(添加一个或多个地址)
答案 0 :(得分:0)
我认为你的问题是约束,你应该写一些类似的东西:
namespace BN\Bundle\XxBundle\Entity;
use Symfony\Component\Validator\Constraints as Assert;
use Doctrine\ORM\Mapping as ORM;
/**
* Adresse
*
* @ORM\Table(name="adresse")
* @ORM\Entity
* @ORM\HasLifecycleCallbacks()
*/
class Adresse
{
//...
/**
* @var string
*
* @ORM\Column(name="adresse1", type="string", length=250, nullable=true)
* @Assert\Null()
*/
private $adresse1;
//...
}
如果我错了,请告诉我。祝你好运!
