CodeIgniter session available in one controller but not in other - php

Question

CodeIgniter session available in one controller but not in other...
Session is setting user controller
class User extends CI_Controller {
// SEssion worked here
public function __construct()
{
parent::__construct();
session_start();
}
function setSess (){
// database model call, Value comes from database
$_SESSION['user'] = array ( 'isLoggedIn' => true,
'id' => $userData[0]['id'],
'username' => 'ABC',
'email_address' => $userData[0]['email_address'],
'country' => $userData[0]['country'],
'lastLoggedin' => $lastLoginTime
);
// Redirect to profile
}
}
Unable to receive it in
class Profile extends CI_Controller {
public function __construct()
{
parent::__construct();
session_start();
}
public function index() {}
public function display() {
ECHO "<PRE>";
print_r($_SESSION);
$data['title'] = 'Profile of '.$_SESSION['user']['username'];
// Gives error here while echoing $_SESSION['user']['username']
}
}
What am i missing here? Any suggestion?

Do not use session_start(), instead, load CodeIgniter session library
In User Controller:
class User extends CI_Controller {
public function __construct()
{
parent::__construct();
if(!isset($this->session)) {
$this->load->library('session'); # do not use 'session_start();'
}
}
function setSess (){
$_SESSION['user'] = array ( 'isLoggedIn' => true,
'id' => $userData[0]['id'],
'username' => 'ABC',
'email_address' => $userData[0]['email_address'],
'country' => $userData[0]['country'],
'lastLoggedin' => $lastLoginTime
);
}
...
}
In Profile Controller:
class Profile extends CI_Controller {
public function __construct()
{
parent::__construct();
if(!isset($this->session)) {
$this->load->library('session');
}
}
...
}
Also make sure your config file is setup correctly. Follow documentation here CodeIgniter Sessions
