Session in CI 4 is not working accross the controller

Home.php

PHP Code:

<?php namespace App\Controllers;
use Config\Services;
class Home extends BaseController
{      public $session;
        function __construct()
        { 
            
            if (session_status() == PHP_SESSION_NONE)
            {
                $this->session = Services::session();
            }
        }
public function index()
{
            $user = array(
                'one','two'
            );
                    
            $this->session->set('usr',$user);
           return view('welcome_message');
}

//--------------------------------------------------------------------

} 


TestSession.php

PHP Code:

<?php namespace App\Controllers;
use Config\Services;
class TestSession extends BaseController
{      public $session;
        function __construct()
        { 
           
            if (session_status() == PHP_SESSION_NONE)
            {
                $this->session = Services::session();
            }
        }
public function index()
{
            
            echo '<pre>';
            print_r($this->session->user); // Not printing the the session data assigned in Home.php PLease help what should i do.?
}

//--------------------------------------------------------------------

} 


I load it  in the BaseController.

And access it like this using the session helper:

PHP Code:

// Get session value using session helper
$user = session('user');
$value = session()->get('Item');
$value = session('Item');

// Save session value using session helper
session()->set('user', $this->user->id);
session()->set($userData);
session()->setFlashdata('error', lang('Auth.notLoggedIn')); 


What did you Try? What did you Get? What did you Expect?

Please, show all code your BaseController . Thank you in advance for your answer

Here you go, just remove the helpers and put your own in.

You will always have access to $this->session as long as your controllers extend the BaseController.

PHP Code:

<?php
namespace App\Controllers;

/**
 * Class BaseController
 *
 * BaseController provides a convenient place for loading components
 * and performing functions that are needed by all your controllers.
 * Extend this class in any new controllers:
 *     class Home extends BaseController
 *
 * For security be sure to declare any new methods as protected or private.
 *
 * @package CodeIgniter
 */

use CodeIgniter\Controller;

use CodeIgniter\HTTP\ResponseInterface;
use CodeIgniter\Services;
use Psr\Log\LoggerInterface;

class BaseController extends Controller

    protected $helpers = [
        'auth',
        'utility',
    ];

    /**
     * @var string
     * Holds the session instance
     */
    protected $session;

    /**
     * Constructor.
     */
    public function initController(RequestInterface $request, ResponseInterface $response, LoggerInterface $logger)
    {
        // Do Not Edit This Line
        parent::initController($request, $response, $logger);

        //--------------------------------------------------------------------
        // Preload any models, libraries, etc, here.
        //--------------------------------------------------------------------
        // E.g.:
        // $this->session = \Config\Services::session();

        // Ensure that the session is started and running
        if (session_status() == PHP_SESSION_NONE)
        {
            $this->session = Services::session();
        }
    }

This question is old, but if you want access to the session in the constructor, then it is not working. The initController function is called after the constructor is called.

I encountered this problem recently.
For me the reason was using hard-coded url: https://www.abcd.com. While the browser url was without “www” ie. https://abcd.com.
So instead of hard coded url, i used base_url( ) to generate the base-url automatically.
And that solved the session problem, and it is now working in all functions.
