php - Session are lost after redirect in CodeIgniter 3

Question

I would like to have some help in CodeIgniter 3. Every time I login and redirect to the index page, session is lost.

Here is my code:

Controller:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Secretariat extends CI_Controller {
    public function __construct(){
        parent::__construct();
        $this->load->helper(array('form', 'url'));
        $this->load->model('SecretariatModel');
        $this->load->model('IndiRegModel');
        $this->load->model('RoomModel');
        $this->load->model('BuildingModel');
        $this->load->model('BilletModel');
        $this->load->model('BatchRegModel');
        $this->load->library('form_validation');
        $this->load->library('session');
    }

    public function secretariatLogin(){

        if ($this->session->isSecretariat){
            redirect('secretariat/index', $data);


        } else{

            $data['title'] = 'PACSA - Philippine Association of Campus Student Adviser';

            $this->load->view('include/toppage', $data);
            $this->load->view('include/defaultnavbar', $data);
            $this->load->view('pacsa/slider');
            $this->load->view('secretariat/secretariatLogin', $data);
            $this->load->view('include/bottompage');

       }

    }

    public function signin(){
        $secretariat = array(
            'sec_email' => $this->input->post('sec_email'),
            'sec_password' => sha1($this->input->post('sec_password'))
        );

        $user = $this->SecretariatModel->getSecretariat($secretariat);
        //print_r($user->name);die();

        if(!$user == null){

            $newdata = array(
                'sec_id' => $user->sec_id,
                'sec_name'  => $user->sec_name,
                'sec_lastname' => $user->sec_lastname,
                'sec_email' => $user->sec_email,
                'sec_password' => $user->sec_password,
                'sec_status' => $user->sec_status,
                'sec_address' => $user->sec_address,
                'logged_in' => TRUE,
                'isSecretariat' => TRUE
            );

            $this->session->set_userdata($newdata);            
            redirect('secretariat/index');
        } else {
            $data['title'] = 'PACSA - Philippine Association of Campus Student Adviser';
            $data['message'] = 'Invalid email or password';

            $this->load->view('include/toppage', $data);
            $this->load->view('include/defaultnavbar', $data);
            $this->load->view('pacsa/slider');
            $this->load->view('secretariat/secretariatLogin', $data);
            $this->load->view('include/bottompage');
        }
    }    

    public function index(){
        $data['title'] = 'PACSA - Philippine Association of Campus Student Adviser';
        $id = $this->session->sec_id;
        var_dump($id);
        echo die();

        $this->load->view('include/toppage', $data);
        $this->load->view('include/secretariatnavbar', $data);
        $this->load->view('pacsa/slider');
        $this->load->view('secretariat/index', $data);
        $this->load->view('include/bottompage');
    }
}

So after redirecting to the index page, I want to verify if there is a session involved. I tried to echo the id and the name of the user but I get a null value.

This kind of problem is often due to incorrect session and/or cookie configuration. Please show those `$config` settings. — DFriend, Jan 28 '18 at 15:50

also check your php.ini file for this option:

session.auto_start=1

where can i locate the .ini file? – Kyle Cipriano Jan 28 '18 at 10:39
what is your OS or server platform? Usually session problem occur when I running my web on localhost using XAMPP. The php.ini is in **drive:/xampp/php/** or you can create a new **.php** file on your server, and write following code: `` and open it from your browser, it will show all parameters of your server including your php configuration file (**php.ini**) location – Sofyan Thayf Jan 28 '18 at 12:38
Works for me. I thought the problem is in the framework! Thank you! – Albert Israel Nov 25 '18 at 07:59
Worked for me! The problem was with XAMPP on mac. By default it is set to session.auto_start=0 – CaptainZero Feb 04 '19 at 08:10

Go to

system/libraries/Session/session.php

at Line no 281 and replace

ini_set('session.name', $params['cookie_name']);

by

ini_set('session.id', $params['cookie_name']);

This problem occurs normally while upgrading PHP later version to 7.3 +

Have you loaded your session library

this->load->library('session')

Or via autoload

$autoload['libraries'] = array('session');

yes i have it loaded on my controller constructor and yes it also loaded in the autoload.php – Kyle Cipriano Jan 28 '18 at 10:38
@KyleCipriano You don't need to load it in your controller if it is loaded in your `autoload.php` file – cusmar Jan 28 '18 at 11:16
Codeigniter will automatically ignore it if its loaded – Ntiyiso Rikhotso Jan 28 '18 at 11:18
Are there any other libraries that you are using that are session related? – Ntiyiso Rikhotso Jan 28 '18 at 11:18
no. just the session itself from the controller or from the autoload – Kyle Cipriano Jan 28 '18 at 12:01

I experienced this problem with the $config['sess_driver'] set to 'database'.

I was using a valid MySQL user so CodeIgniter 3 was not complaining about the sql connection but the user did not have all the right permissions to read/write from the table php_sessions (or the one set by $config['sess_save_path']).

In my case, I was using the default user 'debian-sys-maint' in my database.php.

Your problem doesn't come from the session itself.

Try to:

Comment the redirect method and add a var_dump($user) instead to see if your $user is correctly set. The problem could come from your $user object which contains null values for id and name.
Change if(!$user == null){ by if ($user != null) { or if ($user) {.

Thank you. ok i tried to use var_dump on the $user and i got all the data from the user which i try to login then i did what you told me to change the if statement but when i use the var dump on the index to check if i get the id and name from the session, i still get NULL value – Kyle Cipriano Jan 28 '18 at 11:40
In your index method, can you tell me the result of `var_dump($this->session->userdata())`? – cusmar Jan 28 '18 at 11:46
hmmm i got this result array(1) { ["__ci_last_regenerate"]=> int(1517140453) } – Kyle Cipriano Jan 28 '18 at 11:54
Comment the `redirect('secretariat/index');` line again, and add this instead, just after `set_userdata`: `var_dump($this->session->userdata());`. What is the result here? – cusmar Jan 28 '18 at 11:57
i got this result array(10) { ["__ci_last_regenerate"]=> int(1517140803) ["sec_id"]=> string(1) "1" ["sec_name"]=> string(11) "Secretariat" ["sec_lastname"]=> string(9) "asdfghjkl" ["sec_email"]=> string(11) "secretariat" ["sec_password"]=> string(40) "92a87dfd4ec6c963caeb9e47ea97dd6f4f9c8441" ["sec_status"]=> string(6) "Single" ["sec_address"]=> string(10) "asdfghjkl;" ["logged_in"]=> bool(true) ["isSecretariat"]=> bool(true) } i got all the data from the user which i am trying to log in – Kyle Cipriano Jan 28 '18 at 11:59
Which driver are you using to store your sessions? Look at [Database Driver](https://www.codeigniter.com/user_guide/libraries/sessions.html#database-driver), and try again after you create the `ci_sessions` table and change your config file as it is said in the link below. Does it work? – cusmar Jan 28 '18 at 12:02
here's what i found on my config file : $config['sess_driver'] = 'files'; $config['sess_cookie_name'] = 'ci_session'; $config['sess_expiration'] = 7200; $config['sess_save_path'] = NULL; $config['sess_match_ip'] = FALSE; $config['sess_time_to_update'] = 300; $config['sess_regenerate_destroy'] = FALSE; should i set my 'sess_save_path' to ci_session? and my 'sess_driver' to database? will try this one thanks – Kyle Cipriano Jan 28 '18 at 12:18
Yes you should try and create a new table in your database as it is explicated on the [documentation link](https://www.codeigniter.com/user_guide/libraries/sessions.html#database-driver). – cusmar Jan 28 '18 at 12:21
when i set my 'sess_driver' to database am i going to literally put 'database' or am i going to put my database name – Kyle Cipriano Jan 28 '18 at 12:30
Only put the word "database" – cusmar Jan 28 '18 at 12:32

Did you try to login again? – cusmar Jan 28 '18 at 12:52

If you are using PHP 7.1+/7.2 then this problem will happen. Change PHP version to down (to check if it works).

We also get same issues. our spec : InvoicePlane, PHP 7.0, code igniter v.3.1.11. Every controllers which use redirect() helper got err_connection_refused from browser.

After spend hours exhaustive debugging. We solved this by change IP Address base_url to domain name and set certificate from letsencrypt.

Try this

To see if session is really set and also check if the library is loaded
