<?php
session_start();

ini_set('display_errors', '1');
// added in v4.0.0
require_once 'autoload.php';
require 'functions.php';  

use Facebook\FacebookSession;
use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookResponse;
use Facebook\FacebookSDKException;
use Facebook\FacebookRequestException;
use Facebook\FacebookAuthorizationException;
use Facebook\GraphObject;
use Facebook\EntitiesAccessToken;

// init app with app id and secret
FacebookSession::setDefaultApplication( 'APP ID','APP SECRET' );
// login helper with redirect_uri
    $helper = new FacebookRedirectLoginHelper('http://www.xxxxxxxx.com/3rd_party/fbOAuth/fbconfig.php' );
try {
  $session = $helper->getSessionFromRedirect();
} catch( FacebookRequestException $ex ) {
  // When Facebook returns an error
} catch( Exception $ex ) {
  // When validation fails or other local issues
}
// see if we have a session
if ( isset( $session ) ) {
  // graph api request for user data
  $request = new FacebookRequest( $session, 'GET', '/me' );
  $response = $request->execute();
  // get response
  $graphObject = $response->getGraphObject();
     $fbid = $graphObject->getProperty('id');              // To Get Facebook ID
     $fbfullname = $graphObject->getProperty('name'); // To Get Facebook full name
     $femail = $graphObject->getProperty('email');    // To Get Facebook email ID
 /* ---- Session Variables -----*/
     $_SESSION['FBID'] = $fbid;           
        $_SESSION['FULLNAME'] = $fbfullname;
     $_SESSION['EMAIL'] =  $femail;
  checkuser($fuid,$ffname,$femail);
  header("Location: index.php");
} else {
  $loginUrl = $helper->getLoginUrl();
 header("Location: ".$loginUrl);
