How to access facebook profile picture using facebook php SDK?


I am using the following code to access users profile picture.

<strong>This is how I created the request</strong>

<?php session_start(); include 'facebook-php-sdk/autoload.php'; use Facebook\FacebookRedirectLoginHelper; use Facebook\FacebookRequest; use Facebook\FacebookSession; $permissions = array( 'email', 'user_location', 'user_birthday', 'user_photos', 'public_profile' ); /* Set the public and secret keys */ FacebookSession::setDefaultApplication('XXX', 'XXX'); $helper = new FacebookRedirectLoginHelper('http://localhost/oauth/login.php'); $loginUrl = $helper->getLoginUrl($permissions); // Use the login url on a link or button to redirect to Facebook for authentication ?> <a href="<?php echo $loginUrl; ?>">Login using facebook</a> <?php


<strong>And this is the page user is redirected to..</strong>

<?php session_start(); include 'facebook-php-sdk/autoload.php'; use Facebook\FacebookRedirectLoginHelper; use Facebook\FacebookRequest; use Facebook\FacebookSession; FacebookSession::setDefaultApplication('XXXX', 'XXXX'); $helper = new FacebookRedirectLoginHelper('http://localhost/oauth/login.php'); try { $session = $helper->getSessionFromRedirect(); } catch(FacebookRequestException $ex) { // When Facebook returns an error } catch(\Exception $ex) { // When validation fails or other local issues } if ($session) { // Logged in // $request = new FacebookRequest($session, 'GET', '/me'); // $response = $request->execute(); // $graphObject = $response->getGraphObject(); // var_dump($graphObject->asArray()); $request = new FacebookRequest( $session, 'GET', '/me/picture' ); $response = $request->execute(); $graphObject = $response->getGraphObject(); var_dump($graphObject->asArray()); }


I am always getting output as "array(0) { }" -> an empty array. I cant figure out whats wrong with this code, did I missed some permission while getting login url or anything wrong with the graph query??

<strong>And here's the vardump of $response object</strong>

I expected some default behavior but turns out that extra option is required for the query to be successful.

$request = new FacebookRequest( $session, 'GET', '/me/picture', array ( 'redirect' => false, 'type' => 'large' ) );
