php-如何使用Laravel 5.4中的控制器从数据库传递5个不同数据之和的数据？

我是laravel 5.4的新手,当我查看数据库中具有ID的特定来宾时,我想从数据库中总计5个不同的数据吗？我无法获得总和

这是我的代码：

public function show($id)
{
    $forPayment = ForPayment::where('application_number', $id)->get()->last();

    if (empty($forPayment)) {
        Flash::error('For Payment not found');

        return redirect(route('forPayments.index'));
    }
    $inspection_fee = $forPayment->inspection_fee;
    $storage_fee = $forPayment->storage_fee;
    $cert_fee = $forPayment->cert_fee;
    $local_fee = $forPayment->local_fee;
    $others_fee = $forPayment->others_fee;

    $total_fee = $inspection_fee + $storage_fee + $cert_fee + $local_fee + $others_fee;

    return view('cashier-dashboard.paid.show')->with('forPayment', $forPayment, $total_fee);
}

解决方法:

return view('cashier-dashboard.paid.show',compact('forPayment','total_fee'));

尝试这个
