project

For implementing the Customer user category using the MVC approach in your e-commerce project, you will need to create files to handle different aspects of the functionality. Here’s a breakdown of what files to create for each component of the MVC pattern:

---

1. Model

The Model interacts with the database to handle all data-related logic. For customers, you will need:

Files:

• CustomerModel.php
  • Purpose: Handle customer data operations like registration, login, and fetching profile details.
  • Functions:
    • registerCustomer($data)
    • loginCustomer($email, $password)
    • getCustomerDetails($customer_id)
    • updateCustomerDetails($customer_id, $data)
• ProductModel.php
  • Purpose: Handle product data fetching for browsing and details.
  • Functions:
    • getAllProducts()
    • getProductById($product_id)
• CartModel.php
  • Purpose: Handle cart-related operations.
  • Functions:
    • addToCart($customer_id, $product_id, $quantity)
    • getCartItems($customer_id)
    • removeFromCart($cart_item_id)
    • clearCart($customer_id)
• OrderModel.php
  • Purpose: Handle orders and tracking.
  • Functions:
    • placeOrder($customer_id, $cart_data)
    • getOrdersByCustomer($customer_id)
    • getOrderDetails($order_id)

2. View

The View handles what the customer sees on the website. It includes HTML, CSS, and JavaScript for the front end. For AJAX, use JavaScript or a library like jQuery.

Files:

• Main Views:
  • home.php: Displays the homepage and product catalog.
  • product_details.php: Shows detailed information about a specific product.
  • cart.php: Displays cart items with the option to proceed to checkout.
  • checkout.php: Collects shipping and payment details.
  • profile.php: Displays customer profile details and order tracking.
• Partials (Reusable components):
  • header.php: Displays navigation bar, login/register links, and cart count.
  • footer.php: Contains the footer of the website.
• AJAX/JavaScript:
  • product.js: Fetch products via AJAX for display.
  • cart.js: Handle cart operations like adding, removing, or updating items.
  • order.js: Submit orders and fetch order details for tracking.

3. Controller

The Controller acts as an intermediary between Models and Views. It processes requests, interacts with Models, and returns Views.

Files:

• CustomerController.php
  • Purpose: Handle customer-related operations.
  • Functions:
    • register()
    • login()
    • logout()
    • profile()
    • updateProfile()
• ProductController.php
  • Purpose: Handle product-related operations.
  • Functions:
    • browseProducts()
    • viewProduct($product_id)
• CartController.php
  • Purpose: Handle cart operations.
  • Functions:
    • addItem($product_id, $quantity)
    • viewCart()
    • removeItem($cart_item_id)
    • checkout()
• OrderController.php
  • Purpose: Handle order-related operations.
  • Functions:
    • placeOrder()
    • viewOrders()
    • trackOrder($order_id)

Directory Structure

A suggested directory structure for your MVC project could look like this:

project/
├── models/
│   ├── CustomerModel.php
│   ├── ProductModel.php
│   ├── CartModel.php
│   ├── OrderModel.php
├── views/
│   ├── home.php
│   ├── product_details.php
│   ├── cart.php
│   ├── checkout.php
│   ├── profile.php
│   ├── partials/
│   │   ├── header.php
│   │   ├── footer.php
├── controllers/
│   ├── CustomerController.php
│   ├── ProductController.php
│   ├── CartController.php
│   ├── OrderController.php
├── public/
│   ├── js/
│   │   ├── product.js

Flow

1. Customer visits website:
   • ProductController::browseProducts() fetches all products via ProductModel::getAllProducts() and passes data to home.php.
2. Customer logs in or registers:
   • Login: CustomerController::login() checks credentials via CustomerModel::loginCustomer() and redirects to the homepage on success.
   • Registration: CustomerController::register() adds a new user via CustomerModel::registerCustomer().
3. View product details:
   • Clicking a product calls ProductController::viewProduct($product_id), which fetches data from ProductModel::getProductById() and displays it in product_details.php.
4. Add to cart:
   • AJAX request to CartController::addItem() adds the item to the cart via CartModel::addToCart().
5. View cart and checkout:
   • CartController::viewCart() fetches items via CartModel::getCartItems() and displays them in cart.php.
   • Checkout: OrderController::placeOrder() creates an order using OrderModel::placeOrder().
6. View profile and track orders:
   • CustomerController::profile() displays user details and their orders.
   • OrderController::trackOrder($order_id) fetches and displays order tracking details.

This structure keeps your project modular and scalable, adhering to the MVC principles.
