Facebook - get profile picture php sdk - php

Question

Until few months ago I was using this method to get the user's facebook profile picture and was working fine.
public function getUserProfilePic(){
$access_token = $this->facebook_obj->getAccessToken();
$user_id = $this->facebook_obj->getUser();
$response = $this->facebook_obj->api(
"/me/picture",
"GET",
array (
'redirect' => false,
'type' => 'large'
)
);
return (!empty($response['data']['url'])) ? $response['data']['url'] : 'images/default_profile.jpg';
}
But since the new PHP SDK I have some problems with this method. If I afk for 5 minutes on the main menu on my app and than go on the click to go the page where it calls this method I get
"OAuthException : An active access token must be used to query information about the current user" error.
Any thoughts?

Nothing to do with new/old SDK I guess. The user is logged-out, or access token is expired or your handling of the user in session is flawed.
This error is occurred whenever you try to make calls with /me but no user is logged-in to the app.
So, before making the calls, you should always validate the current user and then proceed, something like that-
$user_id = $this->facebook_obj->getUser();
if ($user_id) {
try {
$response = $this->facebook_obj->api(
"/me/picture",
"GET",
array (
'redirect' => false,
'type' => 'large'
)
);
} catch (FacebookApiException $e) {
error_log($e);
}
}else {
// redirect to Facebook login to get a fresh user access_token
$loginUrl = $this->facebook_obj->getLoginUrl();
header('Location: ' . $loginUrl);
}
Edit:
You dont need to do redirect: false and fetching the url from the json. You can directly use the url as the image source:
https://graph.facebook.com/{user-id}/picture?type=large
That's it!
