Symfony Forms embedded forms - php

Question

Following the symfony documentation I am trying to embed a collection to a form. But when sending a post request to my endpoint the embedded form with the People collection stays empty.
My entities:
user.php
<?php
namespace App\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
use Symfony\Component\Security\Core\User\UserInterface;
/**

* #UniqueEntity(fields="email", message="Email already taken")
* #ORM\HasLifecycleCallbacks()
*/
class User implements UserInterface
{
use Mapping\UserTrait;
/**
* #param Person $person
*/
public function addPeople(Person $person)
{
$this->people->add($person);
$person->setOwner($this);

public function removePeople(Person $person)
{
$this->people->removeElement($person);

Now to my form types:
UserType.php
<?php
namespace App\Form;
use App\Entity\User;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\CollectionType;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\Form\Extension\Core\Type\PasswordType;
use Symfony\Component\Form\Extension\Core\Type\RepeatedType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class UserType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('email', EmailType::class)
->add('plainPassword', PasswordType::class)
->add(
"people",
CollectionType::class,
[
'entry_type' => PersonType::class,
'allow_add' => true,
'by_reference' => false,
]
);
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(
[
'data_class' => User::class,
'csrf_protection' => false
]
);
}
}
PersonType.php
<?php
namespace App\Form;
use App\Entity\Person;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class PersonType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('familyName', TextType::class)
->add('givenName', TextType::class);
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(
[
'data_class' => Person::class,
'csrf_protection' => false,
]
);
}
}
Using this Types I am now trying to register a user and create a Person and add it to the user using this code:
/**
* #Route("/register")
* #param Request $request
* #param UserPasswordEncoderInterface $passwordEncoder
*/
public function register(Request $request, UserPasswordEncoderInterface $passwordEncoder)
{
$user = new User();
$form = $this->createForm(UserType::class, $user);
$form->submit($request->request->all());
if ($form->isSubmitted() && $form->isValid()) {
$password = $passwordEncoder->encodePassword($user, $user->getPlainPassword());
$user->setHash($password);
$entityManager = $this->getDoctrine()->getManager();
$entityManager->persist($user);
$entityManager->flush();
return new Response("ok", 300);
}
return new Response("not ok", 500);
}
My problem now is that when I send a post request with postman with following parameters and content:
email: test#test.de
plainPassword: test1234
people.familyName: testLastname
people.givenName: testFirstname
I get the following error which means that it does not recognize the data for the person entity
"This form should not contain extra fields."
How do I make symfony forms to recognize that people.givenName and people.familyName are meant to create a instance of Person
Edit: comment by u_mulder suggested to change the post body to person[0].givenName and now I am getting the error message
This value is not valid.

Answer 1

I had two problems which had to be fixed. First hint from u_mulder was that I have to use the index for people since its a collection. So instead of
people["givenName"]
I had to use
people[0]["givenName"]
Second mistake was that the structure of the postman body was wrong. Instead of
people[0]["givenName"]
I had to remove the quotes.
people[0][givenName]
After fixing both problems the forms work as expected.
