Php – An active access token must be used to query information about the current user

facebookfacebook-graph-apiPHP

I keep getting the error in the title, while using a simple code:

require_once('sdk/src/facebook.php');
require_once("AppInfo.php");
function idx(array $array, $key, $default = null) {
  return array_key_exists($key, $array) ? $array[$key] : $default;
}
function he($str) {
  return htmlentities($str, ENT_QUOTES, "UTF-8");
}
$facebook = new Facebook(array(
  'appId'  => AppInfo::appID(),
  'secret' => AppInfo::appSecret(),
  'sharedSession' => true,
  'trustForwarded' => true,
));

$arrayForJSON=array();
$user = $facebook->getUser();
$friends = idx($facebook->api('/me/friends'), 'data', array());
if ($friends) {
  $arrayForJSON['friends']=$friends;
}
print_r($friends);

I really don't know how to solve it, I've been searching and trying many answers on stackoverflow

You need to set the access token to be able to get data or act on behalf of the user. Are you going through a login flow to allow authorization to your Facebook application?

Try the example at https://developers.facebook.com/docs/reference/php/facebook-api/

It provides the very basic login flow that will grant access to the data you're seeking.

Just check for the current Facebook user id $user and if it returned null then you need to reauthorize the user (or use the custom $_SESSION user id value - not recommended)

require 'facebook/src/facebook.php';


// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
  'appId'  => 'APP_ID',
  'secret' => 'APP_SECRET',
));

$user = $facebook->getUser();

$photo_details = array('message' => 'my place');
$file='photos/my.jpg'; //Example image file
$photo_details['image'] = '@' . realpath($file);

if ($user) {
  try {
    // We have a valid FB session, so we can use 'me'
    $upload_photo = $facebook->api('/me/photos', 'post', $photo_details);
  } catch (FacebookApiException $e) {
    error_log($e);
  }
}


// login or logout url will be needed depending on current user state.
if ($user) {
  $logoutUrl = $facebook->getLogoutUrl();
} else {
// redirect to Facebook login to get a fresh user access_token
  $loginUrl = $facebook->getLoginUrl();
  header('Location: ' . $loginUrl);
}

I've written a tutorial on how to upload a picture to the user's wall.

Javascript – An active access token must be used to query information about the current user with open graph

I don't see anywhere in your source where you authenticate the user. The user must authorize your application first, as described here: https://developers.facebook.com/docs/authentication/client-side/
