Will be adding some basic information about using the current Facebook API with the PHP SDK. Have been updating a lot of old API integrations over the past 2 months and finally solved many badly documented areas of the new API. Will be updating this in the future, as I dive deeper into the latest API changes.
require_once _DIR_TO_AUTOLOAD.'/facebook_sdk/autoload.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\Entities\AccessToken; use Facebook\HttpClients\FacebookCurlHttpClient; use Facebook\HttpClients\FacebookHttpable;
Depending on what you want to do with the API, the above needs to be adjusted. Check the Facebook API documentation for more details.
// Session should be started after all files have been included // init app with app id and secret FacebookSession::setDefaultApplication( _FB_APP_ID_, _FB_APP_SECRET_ ); // login helper with redirect_uri $helper = new FacebookRedirectLoginHelper( 'http://yourdomain.com/FB_LOGIN/'); // Check for Facebook redirect & retrieve session try { $session = $helper->getSessionFromRedirect(); } catch( FacebookRequestException $ex ) { // When Facebook returns an error } catch( Exception $ex ) { // When validation fails or other local issues } /* Store the session for later reuse, in this case even getting a long lived session. You should store this in your database. The session can be reused with: $session = new FacebookSession($_SESSION['long']->getToken()); */ $_SESSION['long'] = $session->getLongLivedSession(); } // graph api request for user data try { $user_profile = (new FacebookRequest( $session, 'GET', '/me' ))->execute()->getGraphObject(GraphUser::className()); echo "Name: " . $user_profile->getName(); } catch(FacebookRequestException $e) { echo "Exception occured, code: " . $e->getCode(); echo " with message: " . $e->getMessage(); } } else { // show login url if no session available // request special permissions, optional. 'manage_pages', 'publish_pages','publish_actions','user_videos' ); echo '<a href="' . $helper->getLoginUrl($params ) . '">Login</a>'; }
