CodeIgniter Session will not be saved

Experts,

i have a little Problem with my sessions. I want to save my login data into the session like this:

checklogin Controller

$user = $this->user_model->user($email, $password);
$user["logged_in"] = TRUE;
var_dump($this->session->set_userdata($user)); // return NULL? is this correct?
var_dump($this->session->all_userdata()); //return the correct data

Now the Session is saved up to a redirect.

Other Controller

var_dump($this->session->all_userdata()); // return session_id,… and a empty user_data array

I think I have the same Problem with the Shopping Cart Class.

Can anyone help?

I got a similar issue when I want to rerun an old website that was built formerly using CI 3.0.6 on a server running PHP 7.3.

I have set a session in one controller.

$this->session->set_userdata('logged_in', TRUE);

Then, the other controllers that are accessed after that cannot retrieve the information while a new record in the session table in the database is stored.

empty($_SESSION['logged_in']); // true
empty($this->session->logged_in); // true

The solution that works for me is as follows.

  1. Set a higher size for the id column in the CI session table. For example, our session table name is ci_sessions.
ALTER TABLE ci_sessions CHANGE id id varchar(128) NOT NULL;
  1. Replace the current CI system directory with newer version. In my case, it works with the system directory from CI 3.1.10.

In summary, a newer CI version is required to be able to interact well with newer PHP (7.1+). It has a longer id value for the stored session record. Rather than downgrading your PHP version, it is better to upgrade the CI version.

I dont know why, but i think my story will help someone who facing the same problem. My problem is just because I forgot to downgrade my Wamp php version, its php 7.1. Looks like my CI not support php 7.1 or higher. So just a few click to downgrade my php, my problem solved.

I added session_start() in the main index.php file. Worked like a charm afterwards.

hmm try add to ci->session and then get data

//assign the CodeIgniter object to a variable

function __construct() {
    parent::__construct ();                     
    $this->ci = & get_instance ();
        }

//add data to ci session

function test(){
     $this->ci->session->set_userdata($user)
}

in the other controller assign the CodeIgniter object to a variable 

function __construct() {
    parent::__construct ();                     
    $this->ci = & get_instance ();
        }

and get the ci user data 

$this->ci->session->all_userdata()

try this..

$user = $this->user_model->user($email, $password);
$user["logged_in"] = TRUE;
$this->session->set_userdata('user',$user);  //set session of users with a name user.

to get the session value u can do..

print_r($this->session->userdata('user')); // prints the user session array..

The set_userdata() function does not have a return value, so it is correct to display null on var_dump().

In order to save custom data to user's session you should check the manual here

The parameter it accepts must be an array.
