Why session is false in Codeigniter? - php

Question

After success autorization I get array with a information about user:
$authdata = array(
'logged_in' => true,
'id_user' => $checked['idUsers'],
'time_auth' => time(),
'status' => $checked['UsersStatus'],
'type' => $checked['UsersTypeAccount'],
);
Then set this array to session Codeigniter(array $checked is not empty, there is a UsersStatus and UsersTypeAccount):
$this->session->set_userdata($authdata);
After do redirect at controller profile:
redirect('profile');
This controllers checks a user session on empty/true:
if ($this->session->userdata("session_id") && $this->session->userdata("type") && (($this->session->userdata("status")){
// Return Success
}
If make var_dump() session:
var_dump($this->session->userdata("type")).'<br>'; // false
var_dump($this->session->userdata("status")).'<br>'; die(); // false
I get a false value, why type and status fields is not true in session?
Edition:
Also I have done:
var_dump($this->session->all_userdata()); die();
Response:
array(5) { ["session_id"]=> string(32) "85d9e0aa1f738c551b4ba649c36f977c" ["ip_address"]=> string(12) "46.32.174.82" ["user_agent"]=> string(109) "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.111 Safari/537.36" ["last_activity"]=> int(1416142399) ["user_data"]=> string(0) "" }
So, session is created, but without fields status, type
From tutorial:
$newdata = array(
'username' => 'johndoe',
'email' => 'johndoe#some-site.com',
'logged_in' => TRUE
);
$this->session->set_userdata($newdata);
Important:
$this->session->set_userdata($authdata);
var_dump($this->session->all_userdata()); die(); // Here I get full session array.

After some a long attempts to resolve this trouble I had decided:
Update Codeigniter to version 2.2
After the code had worked:
Set session:
$this->session->set_userdata($authdata);
Get session:
$type = $this->session->userdata['type'];
$status = $this->session->userdata['status'];
$session_id = $this->session->userdata['session_id'];
It helped me, maybe someone too
