5. 推薦和搜索

為了提供快速便捷的物流服務(wù)，我們需要提供搜索和推薦功能。以下是搜索功能的代碼示例：

// 搜索訂單
public function search_orders(Request $request)
{
    $query = Order::query();

    if ($request->has('status')) {
        $query->where('status', '=', $request->input('status'));
    }

    if ($request->has('created_at')) {
        $query->whereDate('created_at', '=', $request->input('created_at'));
    }

    $orders = $query->get();

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

以上代碼中，我們使用Laravel的查詢構(gòu)建器Query Builder來構(gòu)建訂單查詢的語句，根據(jù)請求中的查詢參數(shù)動態(tài)生成查詢條件，并返回查詢結(jié)果。

四、總結(jié)

本文中，我們介紹了如何使用Laravel框架來開發(fā)一個在線物流平臺，并提供了相應(yīng)的代碼實現(xiàn)。在這個過程中，我們需要考慮系統(tǒng)的整體架構(gòu)、功能模塊的設(shè)計和選用的技術(shù)棧等方面，此外，我們還提供了用戶管理、訂單管理、支付管理、物流路線管理、推薦和搜索等功能的代碼示例。最后，我相信這篇文章能夠幫助讀者對物流平臺的開發(fā)有一個更加全面的了解，也希望能夠?qū)ψx者在實踐中有所幫助。
