I have a strange issue when trying to connect to Facebook php SDK from my WordPress site. I have followed all instructions as shown on Facebook developers and other sites - I have an app on Facebook and I have downloaded the latest Facebook SDK.
session_start();
require_once(ABSPATH . 'facebook-php-sdk-v4-4.0-dev/src/Facebook/FacebookSession.php');
require_once(ABSPATH . 'facebook-php-sdk-v4-4.0-dev/src/Facebook/FacebookRequest.php');
require_once(ABSPATH . 'facebook-php-sdk-v4-4.0-dev/src/Facebook/FacebookResponse.php');
require_once(ABSPATH . 'facebook-php-sdk-v4-4.0-dev/src/Facebook/FacebookSDKException.php');
require_once(ABSPATH . 'facebook-php-sdk-v4-4.0-dev/src/Facebook/FacebookRequestException.php');
require_once(ABSPATH . 'facebook-php-sdk-v4-4.0-dev/src/Facebook/GraphObject.php');
require_once(ABSPATH . 'facebook-php-sdk-v4-4.0-dev/src/Facebook/FacebookRedirectLoginHelper.php');
require_once(ABSPATH . 'facebook-php-sdk-v4-4.0-dev/src/Facebook/FacebookAuthorizationException.php');
require_once(ABSPATH . 'facebook-php-sdk-v4-4.0-dev/src/Facebook/FacebookJavaScriptLoginHelper.php');
use Facebook\FacebookSession;
use Facebook\FacebookJavaScriptLoginHelper;
use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookResponse;
use Facebook\FacebookSDKException;
use Facebook\FacebookRequestException;
use Facebook\FacebookAuthorizationException;
use Facebook\GraphObject;
FacebookSession::setDefaultApplication('172357792955421', 'b0a5bc2aeb8b2a8712c0af6f01e45c1a');
$helper = new FacebookJavaScriptLoginHelper();
try {
$session = $helper->getSession();
} catch(FacebookRequestException $ex) {
echo 'Facebook returns an error';
} catch(\Exception $ex) {
echo 'When validation fails or other local issues';
}
if ($session)
echo 'logged in';
else
echo 'not logged in';
I have also tried:
require_once( ABSPATH . 'facebook-php-sdk-v4-4.0-dev/autoload.php' );
instead of requiring each single php.
The problem is that the page is broken - cut off, with no header and side tab (php error). I dont see any errors or warnings. if I make some of the require_once as comments (with //), then the page is not cut (but then of course this doesn't work).
I guess something in WordPress is doing the problem, but I can't figure out what it is. Appreciate any help with this.
Thanks
UPDATE: I get this php error: on line 3 Parse error: syntax error, unexpected T_OBJECT_OPERATOR in /hermes/bosnaweb03b/b2442/ipg.ibetyouinfo/facebook-php-sdk-v4-4.0-dev/src/Facebook/FacebookResponse.php on line 137
so the problem is in the facebook php files? how can I fix that?
