Sure.. we need better developer documentation.. it's on the radar, but just not there yet.
Once you've obtained the permission from the user, the below request should return their location:
require_once JPATH_SITE.DS.'com_jfbconnect'.DS.'libraries'.DS.'facebook.php';
$jfbcLibrary = JFBConnectFacebookLibrary::getInstance();
$location = $jfbcLibrary->api('/me/location');
You can check if this user is logged in through Facebook first with:
if ($jfbcLibrary->getUserId())
And you can see all the fields that can be fetched through the /me API call on the Facebook page below (with permissions required for each). You can also just do /me/ above and get all the information you can in a big array:
developers.facebook.com/docs/reference/api/user/
Hope that helps, but let us know if you need more info, or run into issues!
Additional permissions
How can I get the additional permissions, which I have defined in the Permissions tab under Configuration.
