CI 4 simple session auth system problem - adelbak - 10-30-2019
Firstly I'm sorry for my very*100 bad Engilsh
Please help to solve this problem, and thank you in advance.
I am programming a site based on an simple session auth system, but I have had two problems
.- Let's take a look at the files:
BaseController.php Controller:
PHP Code:
<?php
namespace App\Controllers;
use CodeIgniter\Controller;
class BaseController extends Controller
{
protected $helpers = [];
protected $session;
protected $validation;
/**
* Constructor.
*/
public function initController(\CodeIgniter\HTTP\RequestInterface $request, \CodeIgniter\HTTP\ResponseInterface $response, \Psr\Log\LoggerInterface $logger)
{
// Do Not Edit This Line
parent::initController($request, $response, $logger);
//--------------------------------------------------------------------
// Preload any models, libraries, etc, here.
//--------------------------------------------------------------------
$this->validation = \Config\Services::validation();
$this->session = \Config\Services::session();
$this->session->start();
}
protected function loggedIn()
{
if($this->session->has('loggedIn'))
{
return redirect()->to(base_url().'/dashboard/index');
}
}
public function notLoggedIn()
{
if(!$this->session->has('loggedIn'))
{
return redirect()->to(base_url().'/auth/index');
}
}
}
Auth.php Controller:
PHP Code:
<?php namespace App\Controllers;
use App\Models\AuthModel;
class Auth extends BaseController
{
protected $authModel;
public function __construct() {
$this->authModel = new AuthModel();
$this->loggedIn();
}
public function index()
{
$data = [
'title' => "Login Page"
];
return view('pages/login', $data);
}
Problem 1: when i browse Auth (auth/index): Call to a member function has() on null Error...Even though I called and start session class/service from initController function in BaseController
.- When the problem is solved in a ugly way by call session class/service inside loggedIn() function like this:
PHP Code:
protected function loggedIn()
{
$this->session = \Config\Services::session();
if($this->session->has('loggedIn'))
{
return redirect()->to(base_url().'/dashboard/index');
}
}
The second problem: the function does not redirect to /dashboard/index, even i'm sure a having a successful login and loggedIn = username not null or empty or false
Help..Thanks

Remove the following line from BaseController. It is not needed because the session library does this for you.
PHP Code:
$this->session->start();
That may be the reason $this->session is coming up null.
Try this change for loggedIn()
PHP Code:
protected function loggedIn()
{
if ($this->session->has('loggedIn'))
{
return redirect()->to(base_url('dashboard/index'));
}
// then not logged in
return redirect()->to(base_url('auth/index'));
}
Then you can remove public function notLoggedIn()
