这看起来是个简单的任务。我通过使用文档来做到这一点，但是我只是没有创建一个新用户。我没有得到任何错误，但我也没有得到用户。我在一个单独的类中创建我的表单，像这样:
class RegisterFormType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder
->add('firstname', 'text', array(
'label' => 'First Name * ',
'attr' => array('placeholder' => 'First Name')))
->add('email', 'email', array(
'label' => 'Email * ',
'attr' => array('placeholder' => 'Email')))
->add('password', 'password', array(
'label' => 'Password * ',
'attr' => array('placeholder' => 'Password')))
->add('save', 'submit', array('label' => 'Register'));
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Mp'ShopBundle'Entity'Users',
));
}
public function getName()
{
return 'register_form_users';
}
}
在我的第二个控制器中，我获得数据库，创建一个新用户并向该用户添加信息?至少我认为我是……这里出了什么问题?
public function registerAction(Request $request)
{
$em = $this->getDoctrine()->getManager();
$products = $em->getRepository('MpShopBundle:Product')->findAll();
$user = new Users();
$form = $this->createForm(new RegisterFormType(), $user);
if ($form->isValid()) {
$firstname = $form->get('firstname')->getData();
$user->setFirstname($firstname);
$email = $form->get('email')->getData();
$user->setEmail($email);
$password = $form->get('password')->getData();
$user->setPassword($password);
$em->persist($user);
$em->flush();
}
return $this->render('MpShopBundle:Frontend:registration.html.twig', array(
'products'=>$products,
'form'=>$form->createView(),
));
}
在$form->isValid()之前添加$form->handleRequest($request)，应该可以工作。因为您正在创建表单，但没有处理来自请求的数据。如果你想的话，你可以看看源代码。
public function registerAction(Request $request)
{
$em = $this->getDoctrine()->getManager();
$products = $em->getRepository('MpShopBundle:Product')->findAll();
$user = new Users();
$form = $this->createForm(new RegisterFormType(), $user);
/** add this code */
$form->handleRequest($request);
/** add this code */
if ($form->isValid()) {
$firstname = $form->get('firstname')->getData();
$user->setFirstname($firstname);
$email = $form->get('email')->getData();
$user->setEmail($email);
$password = $form->get('password')->getData();
$user->setPassword($password);
$em->persist($user);
$em->flush();
}
return $this->render('MpShopBundle:Frontend:registration.html.twig', array(
'products'=>$products,
'form'=>$form->createView(),
));
}
