CI 3+http://www.codeigniter.com/userguide3/libraries/user_agent.html
Below solution is for Codeigniter version 3
$this->load->library('user_agent');if ($this->agent->is_referral()){ echo $this->agent->referrer();}UPDATE: interesting and useful information on how to obtain referrer information with the same user_agent library

How about just
redirect($_SERVER['HTTP_REFERER']);Using php's $_SERVER global variable.
This worked for me!
Put that code in your Login Controler
function index() { $this->load->library('user_agent'); // load user agent library //Set session for the referrer url $this->session->set_userdata('referrer_url', $this->agent->referrer() ); }After Login Redirection Code
// user is authenticated if referrer is thereif( $this->session->userdata('referrer_url') ) { //Store in a variable so that can unset the session $redirect_back = $this->session->userdata('referrer_url'); $this->session->unset_userdata('referrer_url'); redirect( $redirect_back );}
