Question

I am implementing the facebook connect and its working partially well for me. Its successfully loging the user when some login in with facebook. Here is the link for login http://beta-demo.info/party/users/loginByFacebook but after login when i am trying to fetch user detail from facebook its now displaying anything.

Here is the code of of Fb_Connect.php This file is placed in Libraries folder

<?php
include(APPPATH.'libraries/facebook/facebook.php');
class Fb_connect extends Facebook{

    //declare public variables
    public  $user           = NULL;
    public  $user_id        = FALSE;

    public $fb          = FALSE;
    public $fbSession   = FALSE;
    public $appkey      = 0;

    //constructor method.
    public function __construct()
    {
                $CI = & get_instance();
                $CI->config->load("facebook",TRUE);
                $config = $CI->config->item('facebook');
                parent::__construct($config);
                $this->user_id = $this->getUser(); // New code

                $me = null;
                if ($this->user_id) {
                    try {
                        $me = $this->api('/me');
                        $this->user = $me;
                        } catch (FacebookApiException $e) {
                            error_log($e);
                        }
        }
    } 

} // end class

and this is loging function

function loginByFacebook(){
            $this->load->library('fb_connect');
            $param['redirect_uri']=base_url();
            redirect($this->fb_connect->getLoginUrl($param));
    }

function facebook() {   
print('<pre>');
print_r($this->fb_connect);
        if (!$this->fb_connect->user_id) {
        echo 'No working ';
            //Handle not logged in,
        } else {
        echo   $fb_uid = $this->fb_connect->user_id;
         echo  $fb_usr = $this->fb_connect->user;
           //Hanlde user logged in, you can update your session with the available data
           //print_r($fb_usr) will help to see what is returned
        }

This is the working code for me

<?php
   function loginByFacebook()
   {
        $this->load->library('fb_connect');      
        $param = array( 
                        'scope' =>'email,user_location,user_birthday,offline_access',                                                   'redirect_uri' => base_url()
                       );
        redirect($this->fb_connect->getLoginUrl($param));                   

   }

   function facebook()
   {    

        if (!$this->fb_connect->user_id) {      

        } else {        
            $fb_uid = $this->fb_connect->user_id;
            $fb_usr = $this->fb_connect->user;  
            $firstname = $fb_usr['first_name'];
   }
?>
