Introduction
The UsersManager class is part of the TurboDepot library, designed to provide a comprehensive solution for user management in PHP applications. It offers features such as:
- User creation and management
- Authentication and token-based security
- Role-based access control
- Email verification
- Custom user fields
Prerequisites
Before we begin, make sure you have the following:
- PHP version 7 or higher.
- Ensure that you have the necessary PHP extensions for MySQL (or MariaDb) installed.
- Basic understanding of PHP OOP (Object-Oriented Programming).
Download the latest TurboCommons and TurboDepot phar files and place them on your project as dependencies. Then you'll be able to directly use the UsersManager class:
require 'path/to/your/dependencies/folder/turbocommons-php-X.X.X.phar';
require 'path/to/your/dependencies/folder/turbodepot-php-X.X.X.phar';
Setting Up
To start using the UsersManager class, you'll need to have the TurboDepot library installed and a database set up. Here's how to initialize the class:
use org\turbodepot\src\main\php\managers\UsersManager;
use org\turbodepot\src\main\php\managers\DataBaseObjectsManager;
// Have a DataBaseObjectsManager instance ready
$dbObjectsManager = new DataBaseObjectsManager();
$dbObjectsManager->connectMariaDb('host', 'user', 'password', 'database');
// Create a UsersManager instance
$usersManager = new UsersManager($dbObjectsManager);
User Management
Creating a User
To create a new user, use the saveUser method:
use org\turbodepot\src\main\php\model\UserObject;
$user = new UserObject();
$user->userName = 'johndoe';
$userId = $usersManager->saveUser($user);
// Set the user's password
$usersManager->setUserPassword('johndoe', 'securepassword123');
Retrieving a User
You can retrieve a user object by username or token:
$user = $usersManager->findUserByUserName('johndoe');
// or
$user = $usersManager->findUserByToken($token);
Deleting a User
To delete a user:
$usersManager->deleteUser('johndoe');
Authentication
User Login
To authenticate a user and generate a token:
$loginResult = $usersManager->login('johndoe', 'securepassword123');
$token = $loginResult->token;
$user = $loginResult->user;
$operations = $loginResult->operations;
Validating a Token
To check if a token is valid:
$isValid = $usersManager->isTokenValid($token);
Logging Out
To invalidate a token (log out a user):
$usersManager->logout($token);
Role and Operation Management
Creating Roles
To create a new role:
$usersManager->saveRole('admin', 'Administrator role');
$user->roles = ['admin'];
Creating Operations
Operations represent actions that can be performed by users. You can use them later in your application to check if a user is allowed or not to certain functionalities:
$usersManager->saveOperation('edit_posts', 'The user can edit blog posts');
Assigning Operations to Roles
To specify which roles can perform an operation:
$usersManager->setOperationEnabledForRoles('edit_posts', ['admin', 'editor']);
Checking User Permissions
To check if a user is allowed to perform an operation:
$canEditPosts = $usersManager->isUserAllowedTo('johndoe', 'edit_posts');
Email Management
Adding an Email to a User
$usersManager->saveUserMail('johndoe', '[email protected]');
Verifying an Email
Email verification typically involves generating a verification hash, sending it to the user, and then verifying it:
$verificationHash = $usersManager->getUserMailVerificationHash('johndoe', '[email protected]');
// Send this hash to the user via email
// When the user clicks the verification link:
$isVerified = $usersManager->verifyUserMail('johndoe', '[email protected]', $verificationHash);
Advanced Features
Custom User Fields
You can add custom fields to users:
use org\turbodepot\src\main\php\model\DataBaseObject;
$customFields = new DataBaseObject();
$customFields->birthDate = '1990-01-01';
$customFields->favoriteColor = 'blue';
$usersManager->saveUserCustomFields('johndoe', $customFields);
Transaction Management
For operations that require multiple steps, you can use transactions:
try {
$usersManager->transactionBegin();
// Perform multiple operations
$usersManager->saveUser($user);
$usersManager->setUserPassword($user->userName, $password);
$usersManager->saveUserMail($user->userName, $email);
$usersManager->transactionCommit();
} catch (Exception $e) {
$usersManager->transactionRollback();
// Handle the error
}
Best Practices and Security Considerations
- Password Security: Always use setUserPassword() to set passwords, as it handles proper hashing.
- Token Management: Use tokens for authentication after initial login. Never send passwords over the network unnecessarily.
- Role-Based Access Control: Utilize roles and operations to create a fine-grained permission system.
- Email Verification: Implement email verification to ensure the validity of user email addresses.
- Error Handling: Wrap critical operations in try-catch blocks and use transactions where appropriate.
By leveraging the UsersManager class, you can implement a robust, secure, and feature-rich user management system in your PHP applications. Remember to always prioritize security and follow best practices when dealing with user data and authentication.
