UserPasswordHasherInterface Symfony 6.1.2 - symfony

Question

i'm new in this beautiful world :) .
I here because i have a question about symfony.
I have to make a project for my exams, but i'm stuck in hashing password.
I follow the documentation here : https://symfony.com/doc/current/security.html#registering-the-user-hashing-passwords
But i don't know how to declare the $plaintextPassword.
This is my security.yaml
security:
# https://symfony.com/doc/current/security.html#registering-the-user-hashing-passwords
password_hashers:
Symfony\Component#\Security\Core\User\PasswordAuthenticatedUserInterface: 'auto'
This is my user entity:
namespace App\Entity;
use App\Repository\UserRepository;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\PasswordAuthenticatedUserInterface;
use Symfony\Component\Security\Core\User\UserInterface;
/**
* #ORM\Entity(repositoryClass=UserRepository::class)
*/
class User implements UserInterface, PasswordAuthenticatedUserInterface
{
/**
* #ORM\Id
* #ORM\GeneratedValue
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\Column(type="string", length=180, unique=true)
*/
private $email;
/**
* #ORM\Column(type="json")
*/
private $roles = [];
/**
* #ORM\Column(type="string")
*/
private $password;
/**
* #ORM\Column(type="string", length=255)
*/
private $firstname;
/**
* #ORM\Column(type="string", length=255)
*/
private $lastname;
public function getId(): ?int
{
return $this->id;
}
public function getEmail(): ?string
{
return $this->email;
}
public function setEmail(string $email): self
{
$this->email = $email;
return $this;
}
/**
* A visual identifier that represents this user.
*
* #see UserInterface
*/
public function getUserIdentifier(): string
{
return (string) $this->email;
}
/**
* #see UserInterface
*/
public function getRoles(): array
{
$roles = $this->roles;
// guarantee every user at least has ROLE_USER
$roles[] = 'ROLE_USER';
return array_unique($roles);
}
public function setRoles(array $roles): self
{
$this->roles = $roles;
return $this;
}
/**
* #see PasswordAuthenticatedUserInterface
*/
public function getPassword(): string
{
return $this->password;
}
public function setPassword(string $password): self
{
$this->password = $password;
return $this;
}
/**
* #see UserInterface
*/
public function eraseCredentials()
{
// If you store any temporary, sensitive data on the user, clear it here
// $this->plainPassword = null;
}
public function getFirstname(): ?string
{
return $this->firstname;
}
public function setFirstname(string $firstname): self
{
$this->firstname = $firstname;
return $this;
}
public function getLastname(): ?string
{
return $this->lastname;
}
public function setLastname(string $lastname): self
{
$this->lastname = $lastname;
return $this;
}
}
and this is my RegisterController :
namespace App\Controller;
use App\Entity\User;
use App\Form\RegisterType;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\PasswordHasher\Hasher\UserPasswordHasherInterface;
class RegisterController extends AbstractController
{
private $entityManager;
public function __construct(EntityManagerInterface $entityManager){
$this->entityManager = $entityManager;
}
/**
* #Route("/inscription", name="register")
*/
public function index(Request $request, UserPasswordHasherInterface $passwordHasher):
Response
{
$user = new User();
$form = $this->createForm(RegisterType::class, $user);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()){
$user = $form->getData();
/* $password = $passwordHasher->hashPassword($user,$user->getPassword());
$user->setPassword($hashedpassword); */
$hashedPassword = $passwordHasher->hashPassword(
$user,
$plaintextPassword
);
$user->setPassword($hashedPassword);
$this->entityManager->persist($user);
$this->entityManager->flush();
/* dd($user); */
}
return $this->render('url/inscription.html.twig', [
'form' => $form->createView()
]);
}
}
Until then everything was fine, but i don't understand how to use the UserPasswordHasherInterface service, if someone can help me to know how to declare this variable $plaintextpassword to encode my password in database ..
Thanks :)

Answer 1

well,
i found the solution.
$plaintextPassword is a random variable to catch the normal password without being encoded.
Then, i found this documentation : https://symfony.com/doc/current/security/passwords.html
I just forgot to call composer require symfony/password-hasher .
Right now my passwords are encoded in my db :D
