here is a step by step article on how to create a Role based access control for users on Symfony framework:
Create a new Symfony project:
To create a new Symfony project, open a command prompt and type the following command:
composer create-project symfony/website-skeleton my-project
Configure the security component:
To configure the security component, open the file config/packages/security.yaml and add the following:
security:
encoders:
App\Entity\User:
algorithm: bcrypt
providers:
in_memory:
memory: ~
firewalls:
main:
anonymous: ~
http_basic: ~
access_control:
- { path: ^/admin, roles: ROLE_ADMIN }
In this example, we are using the in_memory provider, which is suitable for development purposes. In a production environment, you would want to use a different provider, such as a database provider.
The access_control section defines which paths require which roles. In this case, we are requiring the ROLE_ADMIN role for any path that starts with /admin.
Create a User entity:
To create a User entity, run the following command:
php bin/console make:user
This command will create a new UserFixture in the src/DataFixtures directory.
Create a UserController:
To create a UserController, run the following command:
php bin/console make:controller
This command will create a new UserController in the src/Controller directory.
Update the UserController:
Update the UserController to require authentication for all actions, except the login and registration actions. Here is an example:
/**
* @Route("/user")
*/
class UserController extends AbstractController
{
/**
* @Route("/login", name="app_login")
*/
public function login(AuthenticationUtils $authenticationUtils): Response
{
// ...
}
/**
* @Route("/register", name="app_register")
*/
public function register(Request $request, UserPasswordEncoderInterface $passwordEncoder): Response
{
// ...
}
/**
* @Route("/", name="app_homepage")
* @IsGranted("ROLE_USER")
*/
public function index(): Response
{
// ...
}
/**
* @Route("/admin", name="app_admin")
* @IsGranted("ROLE_ADMIN")
*/
public function admin(): Response
{
// ...
}
}
In this example, we are using the @IsGranted annotation to require the ROLE_USER and ROLE_ADMIN roles for the index and admin actions, respectively.
Create a login form:
To create a login form, update the login action in the UserController. Here is an example:
/**
* @Route("/login", name="app_login")
*/
public function login(AuthenticationUtils $authenticationUtils): Response
{
// get the login error if there is one
$error = $authenticationUtils->getLastAuthenticationError();
// last username entered by the user
$lastUsername
Alternatively, you can run PHP bin/console make:auth - it automatically creates login and logout controller logic.
