$server_info = array_merge($_GET, $_POST, $_COOKIE);
if (isset($server_info['code'])) {
if ($this->state !== null &&
isset($server_info['state']) &&
$this->state === $server_info['state']) {
// CSRF state has done its job, so clear it
$this->state = null;
$this->clearPersistentData('state');
return $server_info['code'];
} else {
self::errorLog('CSRF state token does not match one provided.');
return false;
}
}
return false;
}

Download PHP SDK for Facebook
Now create a folder in your application \ libarires "facebook"
Place the "SRC" folder in the PHP SDK
Now create a file with FacebookApp.php in this folder and put this code
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
require_once( APPPATH . 'libraries/facebook/src/facebook.php' );
class FacebookApp extends Facebook {
var $ci;
var $facebook;
var $scope;
public function __construct() {
$this->ci =& get_instance();
$this->facebook = new Facebook(array('appId' => $this->ci->config- >item('app_id'),'secret' => $this->ci->config->item('app_secret'), 'cookie' => true));
$this->scope = 'public_profile';
}
public function login_url() {
$params = array('scope' => $this->scope);
return $this->facebook->getLoginUrl($params);
}
public function logout_url() {
return $this->facebook->getLogoutUrl(array('next' => base_url() .'logout'));
}
public function getFbObj(){
return $this->facebook;
}
public function get_user() {
$data = array();
$data['fb_user'] = $this->facebook->getUser();
if ($data['fb_user']) {
try {
$data['fb_user_profile'] = $this->facebook->api('/me');
return $data;
} catch (FacebookApiException $e) {
$this->facebook->destroySession();
$fb_login_url = $this->facebook->getLoginUrl(array('scope' => $this->scope));
redirect($fb_login_url, 'refresh');
}
}
}
Now in your controller load this library
$this->load->library('facebook/FacebookApp)
in method
$obj_fb = new FacebookApp();
$fb_user_data = $obj_fb->get_user();
$data['fb_login_url'] = $obj_fb->login_url();
put fb_login_url in the href of the login button and you will now be logged in.
Hope it helps you.

Rahul, I had a similar problem. You can find a pretty good solution here .
If you still can't figure out the solution, why not take a look at the JavaScript SDK . It's pretty straight forward, then use AJAX to react to the response you get from Facebook.
