I save some data in session on my verify controller then I extract this session data into user_activity model and insert session data into activity table. My problem is only username data saved in session and I can get and insert only username data after extracting session on model. I am new in Codeigniter. For this reason It’s very difficult to find out the problem. I am trying several days finding the problem. But unfortunately I can’t. So please, anyone help me. Thanks
VerifyLogin controller:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
session_start();
class VerifyLogin extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->model('user','',TRUE);
$this->load->model('user_activity','',TRUE);
}
function index()
{
//This method will have the credentials validation
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean');
$this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean|callback_check_database');
if($this->form_validation->run() == FALSE)
{
//Field validation failed. User redirected to login page
$this->load->view('login_view');
}
else
{
//Go to private area
redirect('home', 'refresh');
}
}
function check_database($password)
{
//Field validation succeeded. Validate against database
$username = $this->input->post('username');
$vercode = $this->input->post('vercode');
//query the database
$result = $this->user->login($username, $password);
// ip address
$ip_address= $this->user_activity->get_client_ip();
//Retrieving session data and other data
$captcha_code=$_SESSION['captcha'];
$user_agent=$_SERVER['HTTP_USER_AGENT'];
if($result && $captcha_code == $vercode)
{
$sess_array = array();
foreach($result as $row)
{
$sess_array = array(
'username' => $row->username,
'user_agent' => $row->user_agent,
'ip_address' => $row->ip_address,
);
$this->session->set_userdata('logged_in', $sess_array);
//insert user activity
$this->user_activity->activity();
}
return TRUE;
}
else
{
$this->form_validation->set_message('check_database', 'Invalid username or password');
return false;
}
}
}
?>
user_activity model:
<?php
Class User_activity extends CI_Model
{
function activity()
{
if($this->session->userdata('logged_in'))
{
$session_data = $this->session->userdata('logged_in');

session
In CodeIgniter you can store your session value as single or also in array format as below:
If you want store any user’s data in session like userId, userName, userContact etc, then you should store in array:
<?php
$this->load->library('session');
$this->session->set_userdata(array(
'userId' => $user->userId,
'userName' => $user->userName,
'userContact ' => $user->userContact
));
?>
Get in details with Example Demo :
http://devgambit.com/how-to-store-and-get-session-value-in-codeigniter/
First you have load session library.
$this->load->library("session");
You can load it in auto load, which I think is better.
To set session
$this->session->set_userdata("SESSION_NAME","VALUE");
To extract Data
$this->session->userdata("SESSION_NAME");
initialize the Session class in the constructor of controller using
$this->load->library('session');
for example :
function __construct()
{
parent::__construct();
$this->load->model('user','',TRUE);
$this->load->model('user_activity','',TRUE);
$this->load->library('session');
}
In codeigniter we are able to store session values in a database.
In the config.php file make the sess_use_database variable true
$config['sess_use_database'] = TRUE;
$config['sess_table_name'] = 'ci_sessions';
and create a ci_session table in the database
CREATE TABLE IF NOT EXISTS `ci_sessions` (
session_id varchar(40) DEFAULT '0' NOT NULL,
ip_address varchar(45) DEFAULT '0' NOT NULL,
user_agent varchar(120) NOT NULL,
last_activity int(10) unsigned DEFAULT 0 NOT NULL,
user_data text NOT NULL,
PRIMARY KEY (session_id),
KEY `last_activity_idx` (`last_activity`)
);

CI Session Class track information about each user while they browse site.Ci Session class generates its own session data, offering more flexibility for developers.
Initializing a Session
To initialize the Session class manually in our controller constructor use following code.
Adding Custom Session Data
We can add our custom data in session array.To add our data to the session array involves passing an array containing your new data to this function.
$this->session->set_userdata($newarray);
Where $newarray is an associative array containing our new data.
$newarray = array( 'name' => 'manish', 'email' => '[email protected]'); $this->session->set_userdata($newarray);
Retrieving Session
$session_id = $this->session->userdata('session_id');
Above function returns FALSE (boolean) if the session array does not exist.
Retrieving All Session Data
$this->session->all_userdata()
I have taken reference from http://www.tutsway.com/codeigniter-session.php.
