How can I display the Facebook login API errors or messages in the PHP SDK3? There are plenty of error functions inside Facebook_base.php file, how can I call them into PHP and be displayed when the user tries to login?
Below is what in users_controller.php
public function facebook_login() { Configure::load('facebook'); $appId=Configure::read('Facebook.appId'); $app_secret=Configure::read('Facebook.secret'); //SDK3 $facebook = new Facebook(array( 'appId' => $appId, 'secret' => $app_secret, 'default_graph_version' => 'v2.8', )); $facveb_url = 'https://www.mywebsite.com/facebook_connect'; $loginUrl = $facebook->getLoginUrl(array( 'scope' => 'email,public_profile', 'redirect_uri' => $fb_url, 'display'=>'popup', )); $this->redirect($loginUrl); }
