Problem with session

Hi there again

I want to access session in all controllers by using BaseController.

First time to access a site it works fine, also when I navigate everytime to another site (e.g.: first I navigate to "domain.com/users", then to "domain.com/users/login").

But if I reload one site there will be an error like this:

[b]Fatal error[/b]: Uncaught ErrorException: touch(): Unable to create file NULL/ci_sessionbsfep1vfs4hk2m2ndm26dlittj089hnp because No such file or directory in C:\xampp\htdocs\kighlander.local\system\Session\Handlers\FileHandler.php:252 Stack trace: #0 [internal function]: CodeIgniter\Debug\Exceptions->errorHandler(2, 'touch(): Unable...', 'C:\\xampp\\htdocs...', 252, Array) #1 C:\xampp\htdocs\kighlander.local\system\Session\Handlers\FileHandler.php(252): touch('NULL/ci_session...') #2 [internal function]: CodeIgniter\Session\Handlers\FileHandler->write('bsfep1vfs4hk2m2...', '__ci_last_regen...') #3 [internal function]: session_write_close() #4 {main} thrown in [b]C:\xampp\htdocs\kighlander.local\system\Session\Handlers\FileHandler.php[/b] on line [b]252[/b]

Also in the public folder is generated a directory named "NULL".
In it are generated files like:

ci_sessionbsfep1vfs4hk2m2ndm26dlittj089hnp

What is the reason of these effects ?

Is there a solution?

Thanks,
Kighlander

Update: my controllers:

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 Config\Services;

class BaseController extends Controller
{

    /**
     * An array of helpers to be loaded automatically upon
     * class instantiation. These helpers will be available
     * to all other controllers that extend BaseController.
     *
     * @var array
     */
    protected $helpers = [
           'form',
    ];

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


    /**
     * @var array
     * Passes default settings for displaying in views
     */
    public $data = [
        'title' => 'defaultTitle',
    ];

    /**
     * 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.
        //--------------------------------------------------------------------
        // E.g.:
        // $this->session = \Config\Services::session();

        if(session_status() == PHP_SESSION_NONE)
        {
            $this->session = Services::session();
        }
    }

} 


my users controller:

PHP Code:

<?php
/**
 * Created by PhpStorm.
 * User: Kighl
 * Date: 29.03.2020
 * Time: 14:01
 */

namespace App\Controllers;
use CodeIgniter\Controller;

class Users extends BaseController
{
    public function index()
    {
        //$this->data['title'] = 'my new title';
        echo view('users/profile', $this->data);
    }

    public function login()
    {
        echo view('users/login', $this->data);
    }
} 


What is the value assigned to [i]$sessionSavePath[/i] in the file C:\xampp\htdocs\kighlander.local\app\Config\app.php?

My session-variables are:

PHP Code:

public $sessionDriver            = 'CodeIgniter\Session\Handlers\FileHandler';
public $sessionCookieName        = 'ci_session';
public $sessionExpiration        = 7200;
public $sessionSavePath          = WRITEPATH . 'session';
public $sessionMatchIP           = false;
public $sessionTimeToUpdate      = 300;
public $sessionRegenerateDestroy = false; 


is this helpful?

Oh, I've found the reason... After asking me the session-path I checked ALL my configuration files. And after that I store all my configuration in app/config. Before that I had a mix of that with the .env-file...
Now my app running fine.

Thanks !!!

I have a same iusse before update from rc 2 to final 4.0.2.

I solve it uncoment line in BaseController to getup session service.

If you are using the .env file, you should make an adjustment as follows. Otherwise, it continues to create a NULL folder.


app.sessionSavePath = '/writable/session' #path add
