[FIXED] Codeigniter find whether user logged in or not

Issue

In codeigniter I am trying to include a Logger library and in the below code I need to check whether a user has logged in or not and if so, find his user id.

  <?php
    class Logger {

private $CI;

public function __construct() {
    $this->CI =& get_instance();
}

public function request_logger() {
    $uri = $this->CI->uri->uri_string();
    $ip="";
    $userID="";
    //$ip = ip2long($_SERVER['REMOTE_ADDR']);
    $ip = $_SERVER['REMOTE_ADDR'];
        $params = trim(print_r($this->CI->input->post(), TRUE));

    log_message('info', '==============');
    log_message('info', 'URI: ' . $uri);
    log_message('info', '--------------');
    log_message('info', 'PARAMS:' . $params);
    log_message('info', 'IP:' . $ip);
    log_message('info', '==============');
    //if ($this->ion_auth->logged_in())
    if(isset($_POST['user_id']))
    {
        log_message('info', '<== Inside loggedin loop ==>');
        $userID=$this->input->post('user_id');



     }
        log_message('info', 'USERID' . $userID);

}
}
?>

Solution

you can use codeigniter Session class. you can create new session with user data,like this

$newdata = array(
                   'username'  => 'johndoe',
                   'email'     => 'johndoe@some-site.com',
                   'logged_in' => TRUE
               );

$this->session->set_userdata($newdata);

and you can access this data via,

$userId = $this->session->userdata('userid');
