如何利用PHP和Vue实现仓库管理的订单管理功能

<?php

header('Content-Type: application/json');

// 连接数据库
$pdo = new PDO('mysql:host=localhost;dbname=your_database','your_username','your_password');

// 获取所有订单
if ($_SERVER['REQUEST_METHOD'] === 'GET') {
    $stmt = $pdo->prepare('SELECT * FROM orders');
    $stmt->execute();

    $orders = $stmt->fetchAll(PDO::FETCH_ASSOC);

    echo json_encode($orders);
}

// 添加一个新订单
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $customerName = $_POST['customer_name'];
    $productName = $_POST['product_name'];
    $quantity = $_POST['quantity'];
    $orderDate = date('Y-m-d H:i:s');
    $status = '待支付';

    $stmt = $pdo->prepare('INSERT INTO orders (customer_name, product_name, quantity, order_date, status) VALUES (?, ?, ?, ?, ?)');
    $stmt->execute([$customerName, $productName, $quantity, $orderDate, $status]);

    echo json_encode(['message' => 'Order added successfully']);
}

// 更新一个订单
if ($_SERVER['REQUEST_METHOD'] === 'PUT') {
    parse_str(file_get_contents("php://input"), $data);

    $orderId = $data['id'];
    $status = $data['status'];

    $stmt = $pdo->prepare('UPDATE orders SET status = ? WHERE id = ?');
    $stmt->execute([$status, $orderId]);

    echo json_encode(['message' => 'Order updated successfully']);
}

// 删除一个订单
if ($_SERVER['REQUEST_METHOD'] === 'DELETE') {
    parse_str(file_get_contents("php://input"), $data);

    $orderId = $data['id'];

    $stmt = $pdo->prepare('DELETE FROM orders WHERE id = ?');
    $stmt->execute([$orderId]);

    echo json_encode(['message' => 'Order deleted successfully']);
