Hey guys am trying to pass values entered by a user in a form to an ASP.NET controller for processing to a database context. I do not know why the values in the form are not being passed to the controller method with the same parameter names, because when I tr to submit the form, it does nothing. Please help me do this correctly to pass entries from the form to the controller.
Below is mycontroller code
using Cars.Models;
using Microsoft.AspNetCore.Mvc;
namespace Cars.Controllers
{
public class CarController:Controller
{
//declare the reference to database
CarsContext _context ;
public CarController()
{
_context = new CarsContext();
}
[HttpPost]
//this method is supposed to receive the form values
//and insert into the database
public void GetProperties(string make,string model, string year,string nop)
{
//create a new car object
Car car = new Car()
{
Make = make,
Model = model,
Year = Int32.Parse(year),
NoPassengers = Int32.Parse(nop)
};
//create a new database context
_context.Add(car);
//save changes
_context.SaveChanges();
}
//method to get all the cars
public List<Car> GetAllCars()
{
//create a new database context
return _context.Car.ToList();
}
//method to get a car by id
public Car? GetById(int? id)
{
return _context.Car.FirstOrDefault(c => c.Id == id);
}
//method to check if a car exists
public bool Exists(Car obj)
{
return _context.Car.Where(c => c.Id == obj.Id).Any();
}
//return cars whose passenger seats is three or less
public List<Car> ThreePassengers()
{
return _context.Car.Where(c=>c.NoPassengers<=3).ToList();
}
}
}below is my index.cshtml form with the values I need passed to the controller via parameters
@page
@model IndexModel
@{
ViewData["Title"] = "Home page";
}
<div class="text-center">
<h1 class="display-4">Car Property Editor</h1>
<p>Fill out the details of the car in the form below </p>
