This will help you $this->session->all_userdata();. Load session library before this snippet. – Blair

is there any specific data that you want to get that is not available in the codeigniter session class? – Vinegarish

@RahilWazir $this->session->all_userdata(); does not help because it has only single array for each of users, what I am try to do e.x Let say i have 2 users logged in into my sistem user A & B and my issue is how do I get session datas of user B from user A. Am i clear enough and thanks for your help – Academia

@sabri You can create a column status in your user table with default value of 0 and when user logged in execute query and change status value to 1. Query all users whos status is 1 and you will get the data from users whos login. Remember set it back to 0 after logout. – Blair

Answer 1

To get all session data you can use $this->session->all_userdata();

To print all your session variable use this line anywhere in your code :

echo '<pre>'; print_r($this->session->all_userdata());exit;

You can use db session. So data will be stored to the database. See Saving Session Data to a Database

If you have no database support just use cookie and get the data with

$username = 'John Doe';
$this->session->set_userdata('username',$username);
$var = $this->session->userdata;
echo $var['username'];

Yes this would be an solution but in my case I can not use db :) +1 – Academia

You can use session stored in cookkie from the codeigniter config file. – Knuckleduster

Answer 3

To get all users session data.First we need to initialize the Session class manually in our controller constructor use following code.

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

Then we use following code.

$this->session->all_userdata();

Above function return an associative array like the following.

Array
( [session_id] => 4a5b5dca45708ab1a84364eeb455j007 [ip_address] => 127.0.0.1 [user_agent] => Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_7; [last_activity] => 1102132923
)

If you want to see everything the way I've done it is to cast $this->session as array then print_r it.

        $this->load->library('session');
        echo "<pre>". print_r((array)$this->session, true) ."</pre>";

Hope this helps.

Answer 5

If you know how to do this in PHP why not implement that, and not use the codeigniter session class? my experience is that the CI session class breaks pretty badly with ajax calls and proxy servers, so it is best avoided.
