如何在提交到数据库之前修改表单请求的值？

Question

我使用事件监听器检查 user/author 返回的一些值，然后再实际将它们提交给数据库。

我的表单允许 ROLE_USERS 更改实体文章的某些属性（如 statut）。文章具有 statut(Published, Delete) 和 tobecheked('author wants to delete this article', 'null') 等属性，允许 ROLE_ADMIN 轻松查看某些文章。

无论如何。我希望当作者提交 statut=>'DELETE' statut tobechecked 的值变成 => 'author wants to delete this article' .

这是我尝试过的方法，但这不起作用。

class Article extends AbstractType
{
  public function buildForm(FormBuilderInterface $builder, array $options)
  {
    $builder->add('Statut', ...);
            ->add('toBeChecked',  ...);

    $dynamicSubmissionFunc = function (FormEvent $event)
    {
       $data = $event->getData();
       if($data['statut'] == 'DELETE')
       {
           // HOW CAN I MODIFY HERE THE VALUE OF ARTICLE ATTRIBUTE
           $data['toBeChecked'] = 'author wants to delete this article';
           // nothing is changed in the attribute toBeChecked.
       }
    }
    $builder->addEventListener(FormEvents::PRE_SUBMIT, $dynamicSubmissionFunc);
  }
}

好的。我想通了。您需要将数据设置回事件：

$event->setData($data);
