小编ban*_*anh的帖子

我是symfony的新手,想要创建一个简单的联系表单,获取提交的值并将其作为电子邮件发送.我不想在数据库中保存任何内容.

我按照此页面上的文档:https://symfony.com/doc/current/form/without_class.html

我使用上面的代码创建了一个新页面/操作:

/**
 * @Route("/contact", name="page_contact")
 */
public function contact(Request $request)
{
    $defaultData = ['message' => 'Type your message here'];
    $form = $this->createFormBuilder($defaultData)
        ->add('name', TextType::class)
        ->add('email', EmailType::class)
        ->add('message', TextareaType::class)
        ->add('send', SubmitType::class)
        ->getForm();

    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()) {
        // data is an array with "name", "email", and "message" keys
        $data = $form->getData();
    }

    return $this->render('Shop/contact.html.twig', [
        'form' => $form
    ]);
}

但这给了我一个错误:

Symfony\Component\Form\Exception\InvalidArgumentException:
Could not load type "Doctrine\DBAL\Types\TextType": class does not implement "Symfony\Component\Form\FormTypeInterface".
