Question

我有一个简单的表格：

class SignInType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('_username', 'text');
        $builder->add('_password', 'password');
        $builder->add('Sign in', 'submit');
    }

    public function getName()
    {
        return 'sign_in';
    }
}

我打电话给我的登录＆＃39;动作：

public function signInAction()
{
    $form = $this->createForm(new SignInType(), null,
        [ 'action' => $this->generateUrl('my_project_account_sign_in_process') ]
    );

但是，绑定POST请求会导致表单无效，错误为This form should not contain extra fields。它似乎是导致问题的提交按钮 - 我该如何解决？

public function signInProcessAction(Request $request)
{
    $doctrineManager = $this->getDoctrine()->getManager();

    $form = $this->createForm(new SignInType());

    $form->handleRequest($request);
    ...

Answer 1

我通过删除按钮名称中的空格来修复此问题：

public function buildForm(FormBuilderInterface $builder, array $options)
{
    ...
    $builder->add('Sign_in', 'submit');
}

Answer 2

然后错误This form should not contain extra fields肯定是由没有名字的表单引起的。 Symfony无法获取表单字段并尝试获取一些随机的其他元素吗？

Symfony2-提交按钮会导致额外的字段＆＃39;错误
