To create dynamic roles in Symfony, you can follow these steps:

  1. Create a Role entity: First, create a Role entity with properties like name and description. This entity will store the different roles in your application.

// src/Entity/Role.php

namespace AppEntity;

use DoctrineORMMapping as ORM;

/**
 * @ORMEntity()
 * @ORMTable(name="roles")
 */
class Role
{
    /**
     * @ORMId()
     * @ORMGeneratedValue()
     * @ORMColumn(type="integer")
     */
    private $id;

    /**
     * @ORMColumn(type="string", length=255, unique=true)
     */
    private $name;

    /**
     * @ORMColumn(type="string", length=255)
     */
    private $description;
   
    // getter and setter methods
}


  1. Create a Role form: Next, create a RoleFormType to handle the form for creating and editing roles. Include the required fields like name and description in this form.

// src/Form/RoleFormType.php

namespace AppForm;

use AppEntityRole;
use SymfonyComponentFormAbstractType;
use SymfonyComponentFormFormBuilderInterface;
use SymfonyComponentOptionsResolverOptionsResolver;

class RoleFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('name')
            ->add('description');
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => Role::class,
        ]);
    }
}


  1. Create the CRUD operations: Now, set up the necessary routes, controllers, and templates for CRUD operations on roles. This will involve creating methods to handle listing, creating, editing, and deleting roles.
  2. Assign roles to users: In your User entity, include a ManyToMany relationship with roles. This will allow you to assign multiple roles to users dynamically.

// src/Entity/User.php

// ...

use SymfonyBridgeDoctrineValidatorConstraintsUniqueEntity;
use DoctrineCommonCollectionsArrayCollection;
use DoctrineCommonCollectionsCollection;
use SymfonyComponentSecurityCoreUserUserInterface;

/**
 * @ORMEntity(repositoryClass=UserRepository::class)
 * @UniqueEntity(fields={"email"}, message="There is already an account with this email")
 */
class User implements UserInterface
{
    // ...
    
    /**
     * @ORMManyToMany(targetEntity=Role::class, inversedBy="users")
     * @ORMJoinTable(name="user_roles")
     */
    private $roles;
    
    public function __construct()
    {
        $this->roles = new ArrayCollection();
    }

    // ...
    
    public function getRoles(): array
    {
        $roles = $this->roles->map(function (Role $role) {
            return $role->getName();
        })->toArray();

        // guarantee every user at least has ROLE_USER
        $roles[] = 'ROLE_USER';

        return array_unique($roles);
    }
    
    // ...
}


  1. Use roles in security configuration: Finally, configure your security.yaml file to use these dynamic roles for access control in your application.

# config/packages/security.yaml

security:
    # ...

    role_hierarchy:
        ROLE_ADMIN: ROLE_USER
        ROLE_SUPER_ADMIN: ROLE_ADMIN

    access_control:
        - { path: '^/admin', roles: ROLE_ADMIN }
        - { path: '^/super-admin', roles: ROLE_SUPER_ADMIN }
        - { path: '^/user', roles: ROLE_USER }
        # ...


These steps will allow you to create, edit, and assign roles to users dynamically in your Symfony application.
