PHP框架案例研究：探索实际应用的成功实例

// 使用 Eloquent ORM 定义产品模型
class Product extends Model {
    protected $fillable = ['name', 'description', 'price'];
}

// 在控制器中定义订单创建逻辑
class OrderController extends Controller {
    public function create(Request $request) {
        // 验证请求数据
        $validator = Validator::make($request->all(), [
            'products' => 'required|array',
            'payment_method' => 'required|string',
        ]);

        // 如果验证失败，返回错误响应
        if ($validator->fails()) {
            return response()->json([
                'errors' => $validator->errors(),
            ], 422);
        }

        // 创建订单和订单行
        $order = Order::create([
            'user_id' => auth()->id(),
            'payment_method' => $request->payment_method,
        ]);

        foreach ($request->products as $product_id) {
            OrderLine::create([
                'order_id' => $order->id,
                'product_id' => $product_id,
                'quantity' => 1,
            ]);
        }

        // 返回成功响应
        return response()->json(['success' => true, 'order' => $order]);
    }
}

// 使用 Doctrine ORM 定义页面模型
class Page extends ORMEntity {
    protected $id;
    protected $title;
    protected $content;
}

// 在控制器中定义页面创建逻辑
class PageController extends Controller {
    public function create(Request $request) {
        // 验证请求数据
        $validator = $this->createValidator($request);

        // 如果验证失败，返回错误响应
        if (!$validator->passes()) {
            return $this->redirectToRoute('page_index')->withErrors($validator);
        }

        // 创建页面
        $page = new Page();
