在 Symfony2 控制器中获取表单值，Child 不存在 [英] Get form values in Symfony2 controller , Child does not exist

问题描述

输入用户名的源代码是这样的:

This is how the source code of input username is :

<input type="text" id="user_username" name="user[username]" >

当我尝试将其放入控制器时，出现此错误:

When I try to get it in the controller I get this error :

Child "username" does not exist

控制器:

//.......
if ($request->getMethod() == 'POST') {
        $form->handleRequest($request);
        $i = 0;
        $username = $form["username"]->getData();
        $user= $em->getRepository('UsersBundle:User')->findOneByUsername($username);

//.......
}

这是表单类型

class EleveType extends AbstractType
{
 public function buildForm(FormBuilderInterface $builder, array $options)
   {
    $builder
        ->add('user', new UserType())
        ->add('ecole')
        ->add('niveauscolaire')

    ;
}

推荐答案

替换

$username = $form["username"]->getData();

与

$username = $form["user"]["username"]->getData();
