Php Symfony FormType错误

我在创建提供程序时出错

必须管理传递到选项字段的实体。也许可以将它们保存在实体管理器中

My formType PrestatairType

/**

private $admin;

/**

 */
public function __construct($admin = false, $user, $badges = null)
{
    $this->admin = $admin;
    $this->user = $user;
}

/**
 * {@inheritdoc}
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('files', FileType::class, array(
                'required' => false,
                'attr' => array('class' => 'hidden')
            )
        )

（实体是具有标识的对象。它们的标识在您的域中具有概念意义。在CMS应用程序中，每篇文章都有一个唯一的id。您可以通过该id唯一地标识每篇文章。） 我的实体Prestataire.php

谢谢您的帮助。

我认为您需要在实体中将字段$intervention设置为复数：

private $interventions;

然后，您必须在FormType中匹配此项：

// ...
->add('interventions', CollectionType::class, array(
// ...

在添加/删除方法中：

public function addIntervention(\AppBundle\Entity\Intervention $intervention)
{
    $this->interventions[] = $intervention;

    return $this;
}

public function removeIntervention(\AppBundle\Entity\Intervention $interventions)
{
    $this->interventions->removeElement($interventions);
}
