多个用户登录到现有的Codeigniter项目

Question

I have developed a website which have single login access. I want to give different login access to different members. I tried a sample project as Mutiuser in which there are multiple login, but in this I'm unable to integrate my project. Its showing 404 error after login, in url

http://localhost/Multi_user/login/validate

i have added My_Controller.php in application/core folder After this im gettin 404 page not found

My_Controller.php

<?php 

class MY_Controller extends CI_Controller 
{
    public function __construct()
    {
        parent::__construct();
    }

    public function isLoggedIn()
    {
        $this->load->library('session');

        if($this->session->userdata('logged_in') === true) {
            redirect('../dashboard');
        }
    }   

    public function isNotLoggedIn()
    {
        $this->load->library('session');

        if($this->session->userdata('logged_in') !== true) {
            redirect('../../');
        }
    }

}

this is login.php present application/controllers folder

class Login extends CI_Controller {

    public function __construct()
    {
        parent::__construct();

           $this->load->model('login/login_model');         

    }

Always there is two way to get the solution forward and backward process. In Forward Process: Create a replica of your sample project step by step, it will help you to debug your issue. Backward Process: Just remove all unwanted code to get attention on your desired code.
