PHP E-commerce System Development Guide Beginner’s Tutorial

Introduction

PHP is a powerful language for developing e-commerce systems , available in both small and large online stores. This guide will guide beginners in creating a fully functional e-commerce system, including:

• Product Management
• User Management
• Order Processing
• Payment Integration

Prerequisites

• PHP 7.2 or higher
• MySQL database
• Composer package Manager

Set up the project

1. Set up the server environment

Install PHP, MySQL and Composer.

2. Create a project directory

• Create a new directory, such as E-commerce system.
• Enter the directory and initialize a Composer project: composer init

##3. Install dependencies

Install the following Composer dependencies:

composer require doctrine/orm laravel/framework laravel/scoping laravel/ui

Build database

Create a MySQL database and run the following SQL script:

CREATE TABLE products (
  id INT AUTO_INCREMENT,
  name VARCHAR(255) NOT NULL,
  description TEXT NOT NULL,
  price DECIMAL(10,2) NOT NULL,
  PRIMARY KEY (id)
);

CREATE TABLE users (
  id INT AUTO_INCREMENT,
  name VARCHAR(255) NOT NULL,
  email VARCHAR(255) NOT NULL,
  password VARCHAR(255) NOT NULL,
  PRIMARY KEY (id)
);

CREATE TABLE orders (
  id INT AUTO_INCREMENT,
  user_id INT NOT NULL,
  product_id INT NOT NULL,
  quantity INT NOT NULL,
  total_amount DECIMAL(10,2) NOT NULL,
  PRIMARY KEY (id),
  FOREIGN KEY (user_id) REFERENCES users(id),
  FOREIGN KEY (product_id) REFERENCES products(id)
);

Practical case

1. Create product model

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    //
}

2. Define routing

in

web.php Define the route:

<?php

use Illuminate\Support\Facades\Route;

Route::get('/products', 'ProductController@index');
Route::post('/products', 'ProductController@store');
Route::get('/products/{product}', 'ProductController@show');
Route::put('/products/{product}', 'ProductController@update');
Route::delete('/products/{product}', 'ProductController@destroy');

Route::post('/orders', 'OrderController@store');

3. Implement the controller method

Implement the controller method in

ProductController.php:

<?php

namespace App\Http\Controllers;

use App\Models\Product;
use Illuminate\Http\Request;

class ProductController extends Controller
{
    public function index()
    {
        // 获取所有产品
        $products = Product::all();

        return view('products.index', ['products' => $products]);
    }

    public function create()
    {
        return view('products.create');
    }

    public function store(Request $request)
    {
        // 创建并保存新产品
        $product = Product::create($request->all());

        return redirect('/products');
    }

    // ... 省略其他方法
}
