Answer 1

but this one work
<?php
namespace App\Controller\Admin;
use App\Entity\User;
use EasyCorp\Bundle\EasyAdminBundle\Config\KeyValueStore;
use EasyCorp\Bundle\EasyAdminBundle\Context\AdminContext;
use EasyCorp\Bundle\EasyAdminBundle\Dto\EntityDto;
use EasyCorp\Bundle\EasyAdminBundle\Field\Field;
use EasyCorp\Bundle\EasyAdminBundle\Field\FormField;
use Symfony\Component\Form\Extension\Core\Type\PasswordType;
use Symfony\Component\Form\Extension\Core\Type\RepeatedType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\FormEvent;
use Symfony\Component\Form\FormEvents;
use Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface;
class UserCrudController extends AbstractCrudController
{
/** #var UserPasswordEncoderInterface */
private $passwordEncoder;
public static function getEntityFqcn(): string
{
return User::class;
}
public function configureFields(string $pageName): iterable
{
return [
FormField::addPanel('Change password')->setIcon('fa fa-key'),
Field::new('plainPassword', 'New password')->onlyOnForms()
->setFormType(RepeatedType::class)
->setFormTypeOptions([
'type' => PasswordType::class,
'first_options' => ['label' => 'New password'],
'second_options' => ['label' => 'Repeat password'],
]),
];
}
public function createEditFormBuilder(EntityDto $entityDto, KeyValueStore $formOptions, AdminContext $context): FormBuilderInterface
{
$formBuilder = parent::createEditFormBuilder($entityDto, $formOptions, $context);
$this->addEncodePasswordEventListener($formBuilder);
return $formBuilder;
}
public function createNewFormBuilder(EntityDto $entityDto, KeyValueStore $formOptions, AdminContext $context): FormBuilderInterface
{
$formBuilder = parent::createNewFormBuilder($entityDto, $formOptions, $context);
$this->addEncodePasswordEventListener($formBuilder);
return $formBuilder;
}
/**
* #required
*/
public function setEncoder(UserPasswordEncoderInterface $passwordEncoder): void
{
$this->passwordEncoder = $passwordEncoder;
}
protected function addEncodePasswordEventListener(FormBuilderInterface $formBuilder)
{
$formBuilder->addEventListener(FormEvents::SUBMIT, function (FormEvent $event) {
/** #var User $user */
$user = $event->getData();
if ($user->getPlainPassword()) {
$user->setPassword($this->passwordEncoder->encodePassword($user, $user->getPlainPassword()));
}
});
}
}

Answer 2

i tried to add an Event listener so i create this class
<?php
namespace App\Controller\Admin;
use App\Entity\Admin;
use Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface;
use EasyCorp\Bundle\EasyAdminBundle\EventListener\AdminContextListener;
class AdminController extends AdminContextListener
{
/**
* #var UserPasswordEncoderInterface
*/
private $encoder ;
public function __construct(UserPasswordEncoderInterface $encoder)
{
$this->encoder=$encoder;
}
public static function getSetPasswordEvent()
{
return [
BeforeEntityPersistedEvent::class => ['setPassword'],
];
}
public function setPassword(BeforeEntityPersistedEvent $event)
{
$entity = $event->getEntityInstance();
if (!($entity instanceof Admin)) {
return;
}
$encoded = $this->encoder->encodePassword($entity, $entity->getPassword());
$entity->setPassword($encoded);
}
}
and it didn't work too

You should do that when User register, so add this before doing flush(); for new user:
$user = new UserEntity();
$user->setEmail($request->getEmail());
if ($request->getPassword())
{
$createUser->setPassword($this->encoder->encodePassword($user, $request->getPassword()));
}
$this->entityManager->persist($createUser);
$this->entityManager->flush();
$this->entityManager->clear();
Notice: $request containe payload comes form frontend {"email": "", "passwprd": ""}.
Notice: $createUser is a user object to flush.
