Codeigniter session not working in other functions

Question

Hi i have this new type of problem it is that my codeignitor sessions not work in other functions in controller

for example my login3 function

\\Data is coming from here fine
foreach($query as $row)
{

 $name = $row->name;
 $id = $row->id;
$dmail = $row->email;

}

 if(isset($dmail))
{



  $arr = array();


 $arr['name'] = $name;
 $arr['id'] = $id;
 $arr['email'] = $email;


 $this->session->set_userdata("facebooker",$arr);

 $this->load->model('Gift');



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

$der = $this->session->userdata("facebooker");


 $arrr = array();



 $arrr['unamer'] = $der['name'];

 $arrr['ids'] = $der['id'];
 $arrr['email'] = $der['email'];

//After loading the views all data shows fine

$this->load->view("gifttoday/header",$arrr);
$this->load->view("gifttoday/welcome",$arrr);

 }

But when i call the same session in this function but in same controller it shows no data

function profileselect()
{
$this->load->model('Gift');

 $var =array();

 $this->load->library('session');
 // Here i call this session but no data
  $mer = $this->session->userdata("facebooker");
 // When i print all the values of $mer it shows empty array 
 var_dump($mer);
/**
$this->load->view("gifttoday/header",$arrr);
$this->load->view("gifttoday/profilev",$arrr);
**/
  }

I have searched this problem and my people are having this problem with codeignitor sessions but non of the fixes worked for me can any body help me with this.

Answer 1

Better is to load session Library in constructor

public function __construct() 
    {

      $this->load->library('session');
}

Or enable session Library in config.php

Answer 2

You're calling the library after setting the session data which probably overwrites it (in case you already had the session library loaded in the first place):

So this:

$this->session->set_userdata("facebooker",$arr);
$this->load->model('Gift');

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

Should be this:

$this->load->library('session');
$this->session->set_userdata("facebooker",$arr);
$this->load->model('Gift');

But, if you intend to use the session library in several places in your app, it's a better idea to autoload it...

Edit this line in file application/config/autoload.php

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

and then just avoid loading it manually when needed.
