PHP e-commerce system development: detailed function explanation

E-commerce systems are crucial to modern enterprises. As a popular Web development language, PHP is commonly used for building powerful e-commerce solutions. This article will delve into the core functions of the PHP e-commerce system and explain in detail through practical cases.

1. Product Management

  • Add, edit and delete products
  • Manage product categories, attributes and specifications
  • Optimize product search and filtering functions

Code sample (add product):

<?php
// 1. 获取产品数据
$name = $_POST['name'];
$description = $_POST['description'];
$price = $_POST['price'];

// 2. 建立数据库连接并查询语句
$mysqli = new mysqli('localhost', 'user', 'password', 'database');
$stmt = $mysqli->prepare('INSERT INTO products (name, description, price) VALUES (?, ?, ?)');
$stmt->bind_param('sss', $name, $description, $price);

// 3. 执行查询并关闭连接
$stmt->execute();
$stmt->close();
$mysqli->close();

// 4. 重定向到产品列表页
header('Location: product-list.php');
?>

2. Order management

  • Process customer orders, including placing, tracking, and canceling
  • Manage inventory levels and prevent oversales
  • Generate invoices and receipts

## Code example (processing orders):

<?php
// 1. 获取订单数据
$customer_id = $_POST['customer_id'];
$product_id = $_POST['product_id'];
$quantity = $_POST['quantity'];

// 2. 建立数据库连接并查询语句
$mysqli = new mysqli('localhost', 'user', 'password', 'database');
$stmt = $mysqli->prepare('INSERT INTO orders (customer_id, product_id, quantity) VALUES (?, ?, ?)');
$stmt->bind_param('iii', $customer_id, $product_id, $quantity);

// 3. 执行查询并关闭连接
$stmt->execute();
$stmt->close();
$mysqli->close();

// 4. 发送订单确认邮件
$to = 'customer@example.com';
$subject = '订单确认';
$message = '感谢您的订单!您的订单号为:' . $order_id;
mail($to, $subject, $message);

// 5. 重定向到订单列表页
header('Location: order-list.php');
?>

3. Customer Management

    Create, edit and delete customer accounts
  • Management Customer address and contact information
  • Provides account management features such as password resets and order history

Code example (customer registration):

<?php
// 1. 获取客户数据
$name = $_POST['name'];
$email = $_POST['email'];
$password = $_POST['password'];

// 2. 建立数据库连接并查询语句
$mysqli = new mysqli('localhost', 'user', 'password', 'database');
$stmt = $mysqli->prepare('INSERT INTO customers (name, email, password) VALUES (?, ?, ?)');
$stmt->bind_param('sss', $name, $email, $password);

// 3. 执行查询并关闭连接
$stmt->execute();
$stmt->close();
$mysqli->close();

// 4. 发送欢迎电子邮件
$to = $email;
$subject = '欢迎来到我们的商店!';
$message = '感谢您注册!您现在可以享受我们广泛的产品和优惠。';
mail($to, $subject, $message);

// 5. 重定向到登录页
header('Location: login.php');
?>

4. Payment Integration

    Integrate payment gateways such as PayPal and Stripe
  • Process secure transactions and prevent fraud
  • Manage refunds and Returns

Code Example (PayPal Integration):

<?php
// 1. 获取订单数据(已省略)

// 2. 初始化 PayPal 付款
$apiContext = new PayPal\Rest\ApiContext(
    new PayPal\Auth\OAuthTokenCredential(
        'YOUR_CLIENT_ID',
        'YOUR_CLIENT_SECRET'
    )
);
$payment = new PayPal\Api\Payment();
$payment->setIntent('sale');

// 3. 添加交易项目
$itemList = new PayPal\Api\ItemList();
foreach ($order_items as $item) {
    $productInfo = new PayPal\Api\Product();
    $productInfo->setName($item['name']);
    $productInfo->setDescription($item['description']);

    $item = new PayPal\Api\Item();
    $item->setName($item['name']);
    $item->setQuantity($item['quantity']);
    $item->setCurrency('USD');
    $item->setPrice($item['price']);
    $item->setProductInfo($productInfo);

    $itemList->addItem($item);
}

$payment->setItemList($itemList);

// 4. 执行 PayPal 付款并获取付款 ID
$transaction = new PayPal\Api\Transaction();
$amount = new PayPal\Api\Amount();
$amount->setTotal($order_total);
$amount->setCurrency('USD');
$transaction->setAmount($amount);

$payment->addTransaction($transaction);
$response = $payment->create($apiContext);

// 5. 重定向到 PayPal 付款确认页
header('Location: ' . $response->getApprovalLink() . '&useraction=commit');
?>
