Complete Capstone Project: Enterprise E-Commerce & CRM Platform

To culminate this master class, we synthesize every architectural pattern learned across the previous 48 classes into a complete, production-grade Full-Stack Enterprise E-Commerce & CRM Platform. This project serves as an outstanding portfolio piece for job applications and a university-grade final year project for BCA/MCA degrees.

2. Relational Database Schema Design

The platform utilizes 6 interconnected relational database models:

users (id, name, email, password, is_admin, timestamps)
categories (id, name, slug, parent_id, timestamps)
products (id, category_id, title, slug, price, stock, image_path, timestamps)
orders (id, user_id, order_number, total_amount, status, payment_id, timestamps)
order_items (id, order_id, product_id, quantity, unit_price, timestamps)
reviews (id, product_id, user_id, rating, comment, timestamps)

3. The Stripe Checkout Controller Implementation

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Order;
use Stripe\Stripe;
use Stripe\Checkout\Session as StripeSession;

class CheckoutController extends Controller
{
    public function createStripeSession(Request $request)
    {
        Stripe::setApiKey(config('services.stripe.secret'));

        $cart = session('cart', []);
        $lineItems = [];

        foreach ($cart as $item) {
            $lineItems[] = [
                'price_data' => [
                    'currency'     => 'inr',
                    'product_data' => ['name' => $item['name']],
                    'unit_amount'  => $item['price'] * 100, // Amount in paise/cents
                ],
                'quantity'   => $item['quantity'],
            ];
        }

        $session = StripeSession::create([
            'payment_method_types' => ['card'],
            'line_items'           => $lineItems,
            'mode'                 => 'payment',
            'success_url'          => route('checkout.success') . '?session_id={CHECKOUT_SESSION_ID}',
            'cancel_url'           => route('cart.index'),
        ]);

        return redirect($session->url);
    }
}
