Symfony2 sending form data to the database. Nothing happens - php

Question

It looks like a simple task. I am doing this by using the documentation, however I am just not creating a new user. I dont get any errors, but I dont get the user too. I create my form in a seperate class like this:
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';
}
}
In my second controller I get the database, create a new user and add the information to that user? At least I think I am... What is wrong here?
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(),
));
}

Answer 1

Add $form->handleRequest($request) before $form->isValid() and it should work. Because you're creating a form but not proccessing the data from request. You can look at the source if you want.

Answer 2

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(),
));
}
