Summary
With EasyAdmin bundle, you can create admin panel easily:
Symfony 6 and EasyAdmin 4: Admin Panel for User Management System

Well, as to User entity, given it has password field, you must want to hash it before it stored for security.
This post shows how to implement it with EasyAdmin.
Environment
How to hash password
The source code
Here is an example.
Modify src/Controller/Admin/UserCrudController.php
like this:
<?php
namespace App\Controller\Admin;
use App\Entity\User;
use EasyCorp\Bundle\EasyAdminBundle\Config\{Action, Actions, Crud, KeyValueStore};
use EasyCorp\Bundle\EasyAdminBundle\Context\AdminContext;
use EasyCorp\Bundle\EasyAdminBundle\Controller\AbstractCrudController;
use EasyCorp\Bundle\EasyAdminBundle\Dto\EntityDto;
use EasyCorp\Bundle\EasyAdminBundle\Field\{IdField, EmailField, TextField};
use Symfony\Component\Form\Extension\Core\Type\{PasswordType, RepeatedType};
use Symfony\Component\Form\{FormBuilderInterface, FormEvent, FormEvents};
use Symfony\Component\PasswordHasher\Hasher\UserPasswordHasherInterface;
class UserCrudController extends AbstractCrudController
{
public function __construct(
public UserPasswordHasherInterface $userPasswordHasher
) {}
public static function getEntityFqcn(): string
{
return User::class;
}
public function configureActions(Actions $actions): Actions
{
return $actions
->add(Crud::PAGE_EDIT, Action::INDEX)
->add(Crud::PAGE_INDEX, Action::DETAIL)
->add(Crud::PAGE_EDIT, Action::DETAIL)
;
}
public function configureFields(string $pageName): iterable
{
$fields = [
IdField::new('id')->hideOnForm(),
EmailField::new('email'),
];
$password = TextField::new('password')
->setFormType(RepeatedType::class)
->setFormTypeOptions([
'type' => PasswordType::class,
'first_options' => ['label' => 'Password'],
'second_options' => ['label' => '(Repeat)'],
'mapped' => false,
])
->setRequired($pageName === Crud::PAGE_NEW)
->onlyOnForms()
;
$fields[] = $password;
return $fields;
}
public function createNewFormBuilder(EntityDto $entityDto, KeyValueStore $formOptions, AdminContext $context): FormBuilderInterface
{
$formBuilder = parent::createNewFormBuilder($entityDto, $formOptions, $context);
return $this->addPasswordEventListener($formBuilder);
}
public function createEditFormBuilder(EntityDto $entityDto, KeyValueStore $formOptions, AdminContext $context): FormBuilderInterface
{
$formBuilder = parent::createEditFormBuilder($entityDto, $formOptions, $context);
return $this->addPasswordEventListener($formBuilder);
}
private function addPasswordEventListener(FormBuilderInterface $formBuilder): FormBuilderInterface
{
return $formBuilder->addEventListener(FormEvents::POST_SUBMIT, $this->hashPassword());
}
private function hashPassword() {
return function($event) {
$form = $event->getForm();
if (!$form->isValid()) {
return;
}
$password = $form->get('password')->getData();
if ($password === null) {
return;
}
$hash = $this->userPasswordHasher->hashPassword($this->getUser(), $password);
$form->getData()->setPassword($hash);
};
}
}
Description
I will break it down into several parts.
Constructor Property Promotion
This style is valid since PHP 8.0.
public function __construct(
public UserPasswordHasherInterface $userPasswordHasher
) {}
When your PHP version is prior to them, write like below instead:
private $userPasswordHasher;
public function __construct(
UserPasswordHasherInterface $userPasswordHasher
) {
$this->userPasswordHasher = $userPasswordHasher;
}
Add menus
This is optional. Menus are added to index page and edit.
public function configureActions(Actions $actions): Actions
{
return $actions
->add(Crud::PAGE_EDIT, Action::INDEX)
->add(Crud::PAGE_INDEX, Action::DETAIL)
->add(Crud::PAGE_EDIT, Action::DETAIL)
;
}
Generate password field
configureFields
is one of EasyAdmin's functions to configure the fields to display.
Here, password field is defined as PasswordType and RepeatedType. Also, it is as an unmapped field to prevent validation exception in the case when null is set in order not to change password.
public function configureFields(string $pageName): iterable
{
$fields = [
IdField::new('id')->hideOnForm(),
EmailField::new('email'),
];
$password = TextField::new('password')
->setFormType(RepeatedType::class)
->setFormTypeOptions([
'type' => PasswordType::class,
'first_options' => ['label' => 'Password'],
'second_options' => ['label' => '(Repeat)'],
'mapped' => false,
])
->setRequired($pageName === Crud::PAGE_NEW)
->onlyOnForms()
;
$fields[] = $password;
return $fields;
}
Handle events
Here, Symfony form events are used with EasyAdmin event handlers. It's because as of now EasyAdmin's events don't support handling form validation.
public function createNewFormBuilder(EntityDto $entityDto, KeyValueStore $formOptions, AdminContext $context): FormBuilderInterface
{
$formBuilder = parent::createNewFormBuilder($entityDto, $formOptions, $context);
return $this->addPasswordEventListener($formBuilder);
}
public function createEditFormBuilder(EntityDto $entityDto, KeyValueStore $formOptions, AdminContext $context): FormBuilderInterface
{
$formBuilder = parent::createEditFormBuilder($entityDto, $formOptions, $context);
return $this->addPasswordEventListener($formBuilder);
}
private function addPasswordEventListener(FormBuilderInterface $formBuilder): FormBuilderInterface
{
return $formBuilder->addEventListener(FormEvents::POST_SUBMIT, $this->hashPassword());
}
Hash password
This is the key part on hashing password with Symfony's PasswordHasher.
When password is not entered, skip the field.
When it is, hash it✨ and add the field to the entity data🌟
private function hashPassword() {
return function($event) {
$form = $event->getForm();
if (!$form->isValid()) {
return;
}
$password = $form->get('password')->getData();
if ($password === null) {
return;
}
$hash = $this->userPasswordHasher->hashPassword($this->getUser(), $password);
$form->getData()->setPassword($hash);
};
}
That's it.
I'm happy if the code and the description would help you :)

Hey!
Since Symfony 6.2, you can use the field option 'hash_property_path'.
It could be used this way :
$password = TextField::new('password')
->setFormType(RepeatedType::class)
->setFormTypeOptions([
'type' => PasswordType::class,
'first_options' => [
'label' => 'Password',
'hash_property_path' => 'password',
],
'second_options' => ['label' => '(Repeat)'],
'mapped' => false,
])
->setRequired($pageName === Crud::PAGE_NEW)
->onlyOnForms()
;
Hi ! Thank you for your useful information.
It's really great !!!
symfony.com/doc/current/reference/...
symfony.com/doc/current/security/p...
This is usefull for my why with Symfony 7 - EasyAdmin 4 - Php 8.2 can't set event and also the your code it's very simple. Thank you !!!
This is very helpful. Thank you
Eugenii, I'm really happy to hear it ☺️ Thank you for your comments.
Great article, thank you very much!
I was working with EasyAdmin anonymously and faced with the issue that
$this->getUser()
wasnull
. I had to replace it with$form->getData()
.But this led me to a question: is it okay that we hash the password for an authorized user instead of doing it for a new user?
Hello, Michael. Thank you for your comments.
Well, it's up to how your system registers users:
When it follows the current Symfony Secutiry with login form and you will implement the same way in which passwords are hashed, it has already stored password hashed correctly. You can apply hash to existing users.
However, when the registration system didn't use hash or used in another way, it's not the case. When you want to implement hash against it, recovery might be possible if you would reset password of all existing users.
Thanks! It helped me a lot, i was going nuts because i used the Events System as a Container Service to hash the password (bad idea)
Hello, Alex. Thank you for your comments. It is good news to me 😄
Well, you mean you used custom
EventSubscriber
(orEventListener
) instead ofFormEvents::POST_SUBMIT
? Interested.
