How can I send id to controller action method in ASP.NET MVC?-CodePudding

I am working a project and I had some trouble. I want to send id from html beginform but I couldn't do it.

I want to send /BuyTourTicket/tourid

This is my code:

public ActionResult TourTicket(int id)
{
    var tour = db.TBLTUR.Find(id);
    ViewBag.tourid = tour.id;
    ViewBag.tourname = tour.tur_basligi.ToString();
    ViewBag.kalkisYeri = tour.kalkis_yeri.ToString();
    ViewBag.tarih = tour.tarih.ToString();
    ViewBag.detaylar = tour.detay.ToString();
    ViewBag.turYetkilisi = db.TBLTURYETKILISI.Find(id).ad   " "   db.TBLTURYETKILISI.Find(id).soyad;

    return View("TourTicket",tour);
}

public ActionResult BuyTourTicket()
{
    return View();
}

[HttpPost]
public ActionResult BuyTourTicket(int id)
{
    TBLTURREZERVASYON reservation = new TBLTURREZERVASYON();
    reservation.tur = id;

    db.TBLTURREZERVASYON.Add(reservation);
    db.SaveChanges();

    return View();
}

This is the error I get:

CodePudding user response：

The first, the default route usually describes the id parameter as optional. Therefore change the action method declaration to public ActionResult BuyTourTicket(int? id):

[HttpPost]
public ActionResult BuyTourTicket(int? id)
{
    TBLTURREZERVASYON reservation = new TBLTURREZERVASYON();
    reservation.tur = id;
    db.TBLTURREZERVASYON.Add(reservation);
    db.SaveChanges();

    return View();
}

The second, change the parameters order in the Html.BeginForm() of the TourTicket.cshtml to:

@using (Html.BeginForm("BuyTourTicket", "Tur", new { id = ViewBag.tourid }, FormMethod.Post))

The route values are third parameter and the HTTP method is the fourth parameter.

I would fix an action route

[HttpPost("{id"})]
 public ActionResult BuyTourTicket(int id)

and add Get to another action

[HttGet]
public ActionResult BuyTourTicket()
    {
        return View();
    }
