userList.php file structure
session_start();
// Must be already set
$_SESSION['username'] = $this->session->userdata('username');
?>
| User Id | User Name |
|---|---|
| user_id; ?> | user_name; ?> |
-application/controllers/chat.php (controller file)
chat.php controller file structure
class Chat extends Controller {
//Global variable to holds the output data for each view
public $outputData;
public $loggedInUser;
function Chat()
{
parent::Controller();
session_start();
//Get Config Details From Db
$this->config->db_config_fetch();
//Manage site Status
if($this->config->item('site_status') == 1)
redirect('offline');
$this->load->model('user_model');
//load Helpers
$this->load->helpers('users');
//Load the session library
$this->load->library('session');
}
} // End of the class

define ('DBPATH','localhost');
define ('DBUSER','root');
define ('DBPASS','');
define ('DBNAME','codeigniter');
3-Go to the model folder and create file named users_model.php
class Users_model extends CI_Model {
/** * Constructor * */
function __Construct() {
parent::__Construct();
}
// --------------------------------------------------------------------
/** * Get Users */
function getUsers($conditions=array(),$fields='') {
parent::__construct();
if(count($conditions)>0)
$this->db->where($conditions);
$this->db->from('ci_users');
$this->db->order_by("ci_users.user_id", "asc");
if($fields!='')
$this->db->select($fields);
else
$this->db->select('ci_users.user_id,ci_users.user_name,ci_users.user_email,ci_users.online');
$result = $this->db->get(); return $result; }
//End of getUsers Function
}
