use App\Http\Controllers\Controller;
use App\Notifications\OrderDelivery;
use Maatwebsite\Excel\Facades\Excel;
use App\Exports\OrdersExport; // ← 加這行
class OrderController extends Controller
{
    

    public function index(Request $request)
{

    $dataPerPage = 5;
        
        $orders = Order::with(['orderItems', 'orderItems.product', 'user'])
                      ->orderBy('created_at', 'desc')
                      ->whereHas('orderItems')
                      ->paginate($dataPerPage);
        
        return view('admin.orders.index', [
            'orders' => $orders,
            'orderCount' => Order::whereHas('orderItems')->count(),
        ]);

}

public function delivery($id)
{
    $order = Order::find($id);
    if ($order->is_shipped) {
        return response(['result' => false]);
    } else {
        $order->update(['is_shipped' => true]);
        $order->user->notify(new OrderDelivery());
        return response(['result' => true]);
    }

}

public function export()
{
    return Excel::download(new OrdersExport,'orders.xlsx');
}

}
