Answer 1

Please check the following points

• In your case, You should not check the session in constructor level. , Means, your controller consists of public & authenticated pages. So it will be looping/redirecting inside this controller only.

• Move the session checking condition to the specific page and redirect to login page if suppose no session for authenticated pages. Below I have checked for user_details page which is I created for your understanding.

• In your login method, you should check the already logged in or not and if yes, it should be go to dashboard page. I have created one method for that IsAlreadyLogged. please check it.

• Don't add session_start() in your controller which will be take care of CI core

• Use build-in redirect method which is CI core has

• You should check session in constructor level if all pages are need to be authenticated in controller.

class Backspaze extends CI_Controller
{
    function __construct()
    {
        parent::__construct();
        $this->load->library('session');
        $this->load->model('getDB');
    }

    function IsLogged()
    {
        if (!$this->session->userdata('id'))
        {
            redirect('login');
        }
    }

    function IsAlreadyLogged()
    {
        if ($this->session->userdata('id'))
        {
            redirect('dashboard');
        }
    }

    function user_details()
    {
        $this->IsLogged();
        $this->load->view('user/details');
    }


    function Login()
    {
        $this->IsAlreadyLogged();
        $this->load->view('Auth/Login');
    }

}

Answer 2

remove the line

session_start();

codeigniter handle it itself.
Replace this

header('Location: '.base_url().'login');

with

  redirect(base_url()."login");` 

but make sure you have loaded url helper
