Architecting the System: MVC and Structure

A well-defined architecture is essential for building a scalable and maintainable restaurant reservation system. The Model-View-Controller (MVC) architectural pattern is a popular choice for its clear separation of concerns. Let's explore how MVC can be applied to this project.

MVC Architecture: A Breakdown

  • Model (app/Models):
    • The Model layer is responsible for data access and business logic. It interacts with the database using PDO (PHP Data Objects) and enforces business rules for each entity, such as users, restaurants, tables, and reservations.
  • View (app/Views):
    • The View layer handles the presentation of data. It uses Bootstrap 5 for styling and a simple templating engine (similar to Blade) for rendering dynamic content. View helpers are used to simplify common tasks.
  • Controller (app/Controllers):
    • The Controller layer acts as an intermediary between the Model and View. It orchestrates the flow of data, handles user input, performs validations, and generates responses.

Core Components and Functionality

  • Front Controller:
    • The public/index.php file serves as the entry point for all requests. It resolves routes to the appropriate controller and action.
  • Router:
    • A simple router manages URL routing, mapping requests to specific controllers and actions. It supports GET and POST methods and can implement middlewares for role-based access control.
  • Services:
    • Services encapsulate business logic and are responsible for tasks such as sending emails, managing notifications, handling availability calculations, and processing payments (optional).
  • Repository Layer (Optional):
    • A repository layer can be added to decouple SQL queries from the Model layer, enhancing maintainability and testability.

Directory Structure: Organizing the Project

A well-organized directory structure is crucial for project maintainability. Here's a suggested structure:

Security Considerations: Protecting the System

Security is paramount when building any web application, especially one that handles sensitive user data. Here are some key security measures to implement in your restaurant reservation system:

  • Password Hashing:
    • Use password_hash() to securely store user passwords. This function creates a one-way hash of the password, making it extremely difficult to reverse engineer.
  • CSRF Protection:
    • Implement CSRF (Cross-Site Request Forgery) tokens in all forms that modify data. This prevents attackers from submitting malicious requests on behalf of authenticated users.
  • Rate Limiting:
    • Implement basic rate limiting by IP address for sensitive operations like login and reservation creation. This helps prevent brute-force attacks and abuse.
  • Input Validation and Output Escaping:
    • Validate and sanitize all user inputs using filter_input() to prevent injection attacks. Escape output using htmlspecialchars() to prevent cross-site scripting (XSS) vulnerabilities.
  • Prepared Statements:
    • Use prepared statements with PDO to prevent SQL injection attacks. Prepared statements ensure that user input is treated as data, not as executable code.

UI/UX with Bootstrap 5: Creating a User-Friendly Interface

A well-designed user interface (UI) and user experience (UX) are crucial for the success of a restaurant reservation system. Bootstrap 5 provides a solid foundation for building a responsive and visually appealing interface. Here are some UI/UX considerations:

  • Color Palette:
    • Use a sober color palette (grays + primary restaurant color) in assets/css/custom.css. This creates a professional and consistent look.
  • Reusable Components:
    • Implement reusable components such as a fixed navbar, cards, modals for table CRUD operations, and toasts for notifications. This promotes consistency and reduces code duplication.
  • Forms and Validation:
    • Use HTML5 validation combined with Bootstrap's JavaScript validation for client-side form validation. Provide clear and accessible feedback to users.
  • Tables and Pagination:
    • Implement tables with pagination and search (client-side) for large listings. This improves usability and performance.

Getting Started: Setting Up the System

To get your restaurant reservation system up and running, follow these steps:

  1. Set up your development environment:
    • Ensure you have PHP 7.x, MySQL 5.7/8.0, Apache/Nginx, and Composer installed.
  2. Database Setup:
    • Create a new MySQL database for your application.
    • Import the SQL schema from sql/schema.sql to create the necessary tables.
    • Populate the database with sample data for testing purposes.
  3. Configuration:
    • Copy .env.example to .env and configure your database connection settings.
    • Update other configuration settings in config/app.php as needed.
  4. Web Server Configuration:
    • Configure your web server (Apache/Nginx) to point to the public directory.
    • Enable URL rewriting (e.g., using .htaccess for Apache) to remove index.php from URLs.
  5. Run the Application:
    • Start your web server and access the application in your browser.
