      }
      else
      {
      ModelState.AddModelError("", "Wrong data");
      }

      // return user model/object to the view
      return View(user);
      }

      // Check if user is valid (exists in database etc..)
      private bool isValid(string email, string password)
      {
      bool isValid = false;

      using (PeopleDBContext db = new PeopleDBContext())
      {
      // take user from database
      var user = db.PeopleCon.FirstOrDefault(u => u.Email == email);

      // if user exists
      if (user != null)

      }
      }
