I am trying to get a list of members of our school group. The problem is, if I try it using Graph API explorer, results are ok (to be specific, one of the member's id: 732260790195849)
When I try it using my PHP code, ID differs a little 732293256859269
My PHP code:
<?php
session_start();
?>
<!DOCTYPE html>
...
<?php
require('fbsdk/autoload.php');
use Facebook\FacebookSession;
...
FacebookSession::setDefaultApplication('...', '...');
$helper = new FacebookRedirectLoginHelper( '...' );
try {
$session = $helper->getSessionFromRedirect();
} catch( FacebookRequestException $ex ) {
} catch( Exception $ex ) {
}
if ( isset( $session ) ) {
$request = new FacebookRequest( $session, 'GET', '/mygroupid/members?limit=2000' );
$response = $request->execute();
$data = $response->getGraphObject();
echo '<pre>', var_dump($data), '</pre>';
} else {
echo '<a href="' . $helper->getLoginUrl() . '">Login</a>';
}
?>
</body>
</html>
I am logged as a member of that group..
Any ideas why is this happening ? Thanks for answers.
You're retrieving an app-scoped ID within an application and probably the real (or another scoped) ID with the Graph Explorer. This is to protect user information. In any event, the ID you retrieve will link to the correct person. I'll also add that this ID will never change within the app.
