I am attempting to retrieve the number of fans for my Page via the PHP SDK. Here is all of my code so far.
$fbSession = \Facebook\FacebookSession::newAppSession(self::APP_ID, self::APP_SECRET);
$fbLikesResponse = null;
try {
$fbLikesRequest = new \Facebook\FacebookRequest($fbSession, 'GET', '/{myRealPageIDGoesHere}/insights/page_fans');
$fbLikesResponse = $fbLikesRequest->execute()->getGraphObject()->asArray();
} catch (\Facebook\FacebookRequestException $ex) {
$resp = new \stdClass();
$resp->error = $ex;
return $resp;
} catch (\Exception $ex) {
echo $ex->getMessage();
}
//Add items to response and to store
var_dump($fbLikesResponse);
I never get authentication/authorizaiton errors, but the data response value is always just 0. I can see on the Facebook page itself that there are more than 0 likes.
I really don't want to have to resort to screen-scraping to obtain how many likes my Facebook page has. Any idea why I only get 0s?
Clarification- this is for a server-side call for an analytics engine. No user authentication is involved, so I'm trying to figure out how to get hit the {node}/insights/page_fans endpoint without faking some sort of user login.

I have this simple code, where I'm trying to access a page with an ID. Whenever I run this code, I get an error "Unsupported get request. Please read the Graph API documentation"
$leheid = $page['accounts'][$x]['id'];
try {
$page = $fb->get("$leheid?fields=events", $at);
$page = $page->getGraphPage();
} catch(Facebook\Exceptions\FacebookResponseException $e) {
echo $e->getMessage();
} catch(Facebook\Exceptions\FacebookSDKException $e) {
echo $e->getMessage();
}
Okay, but whenever I run the same code without a variable and with a string, no errors...
If I echo or print the same variable I get the right string with no spaces or anything else in there, so I'm quite confused...
Also, I tried $leheid. '....'
It's an old question but i would like to contribute and maybe help someone else with the same problem.
The reason why the code above didn't work, was because i mistyped the API response function
In short:
$page = $page->getPage();
should have been replaced with
$page = $page->getGraphPage()->asArray();
Which will also give you the response as an array
I'm trying to figure out if a user is following another user on Soundcloud using the Soundcloud API and php.
So far I came across a solution which would either return an object (user) or a 404 error:
$test = json_decode($client->get('/users/{id1}/followers/{id2}'));
I've tried it multiple times with different user IDs but I always receive a the following error message:
'Services_Soundcloud_Invalid_Http_Response_Code_Exception' with message 'The requested URL responded with HTTP code 404.'
I know that this is supposed to be the error message which informs me that user2 is not following user1. However I've tried this snippet with ids where I know a reciprocal following exists for sure.
Any suggestions on how this can be solved?
Update (21.05.15):
I've read through some of the Soundcloud documentation and cam across a code snippet:
<?php
require_once 'Services/Soundcloud.php';
// create a client object with access token
$client = new Services_Soundcloud('YOUR_CLIENT_ID', 'YOUR_CLIENT_SECRET');
$client->setAccessToken('YOUR_ACCESS_TOKEN');
// Follow user with ID 3207
$client->put('/me/followings/3207');
// Unfollow the same user
$client->delete('/me/followings/3207');
// check the status of the relationship
try {
$client->get('/me/followings/3207');
} catch (Services_Soundcloud_Invalid_Http_Response_Code_Exception $e) {
if ($e->getHttpCode() == '404')
print "You are not following user 3207\n";
}
?>
This is pretty much what I was referring to. However if I open a php page with this script the result is always one of three cases:
You are not following user 3207 (expected output)
No output (I'm following the user)
Uncaught exception 'Services_Soundcloud_Invalid_Http_Response_Code_Exception' with message 'The requested URL responded with HTTP code 404.'
The third option is either referring to $client->put or $client->delete
Here is how i would do this:
<?php
require_once 'Services/Soundcloud.php';
$client = new Services_Soundcloud(
'xxxxxxxxxxxxxxxxxxx160', 'xxxxxxxxxxxxxxxxxx34dd1 ');
$userid = 1672444;
$followerid = 383228;
$yesno = '';
try {
$response = json_decode($client->get('users/'.$userid.'/followers'), true);
$yesno = IdInArray($response, $followerid);
echo $yesno;
} catch (Services_Soundcloud_Invalid_Http_Response_Code_Exception $e) {
exit($e->getMessage());
}
function IdInArray($response, $followerid){
echo $followerid.'<br/>';
for($i = 0; $i < count($response); ++$i) {
if($response[$i]['id'] == $followerid){
return 'yolo';
}
else{
return 'nolo';
}
}
}
?>
The situation: I have a finished Facebook canvas app (PHP/CodeIgniter), I just need to add the Facebook-related options such as sharing and inviting friends.
Current task: getting the list of invitable friends from the PHP SDK.
Relevant documentation: https://developers.facebook.com/docs/games/invitable-friends/v2.0
The code: in my Facebook library, I have created the following function.
/**
* Returns the current user's invitable friends
*/
public function get_invitable_friends() {
if ( $this->session ) {
$request = ( new FacebookRequest( $this->session, 'GET', '/me/invitable_friends' ) )->execute();
$graphObject = $request->getGraphObject();
return $graphObject;
}
return false;
}
The condition if($this->session) is because it doesn't make sense to try anything if there's no Facebook session in the first place. This will come into play later.
I've tried calling this function in two ways. The first way works and the second doesn't. I'm gonna present both, and then somebody will hopefully explain to me why the second way doesn't work and how to fix it, as I'd much prefer to use that.
First (working) way:
Call the function from the main controller's index() method, as the page loads. The function correctly returns a list of my friends.
Second (non-working) way:
Create this function in the controller:
//load list of friends we can invite to play the game
public function load_invitable_friends()
{
$this->load->library('facebook');
$list = $this->facebook->get_invitable_friends();
var_dump($list);
}
Then call it through AJAX, like:
function loadInvites(){
$.post(base+"main/load_invitable_friends/",function(resp){
$('#slide_6_inner').html(resp);
});
}
After this call, the content of the slide_6_inner div should contain the list of friends, as dumped by var_dump. However, the content is bool(false), indicating that the Facebook session is no longer present.
If I remove the condition if( $this->session ) from the get_invitable_friends() method, then this error happens:
A PHP Error was encountered
Severity: 4096
Message: Argument 1 passed to Facebook\FacebookRequest::__construct() must be an instance of Facebook\FacebookSession, null given, called in /home/lights/public_html/appname/application/libraries/facebook/Facebook.php on line 125 and defined
Filename: Facebook/FacebookRequest.php
Line Number: 182
The session in Facebook.php is initially created with the following code.
$this->ci =& get_instance();
// Initialize the SDK
FacebookSession::setDefaultApplication( $api_id, $api_secret) );
$this->helper = new FacebookCanvasLoginHelper();
$this->session = $this->helper->getSession();
To sum up - why is this problem occurring and how do I fix it?
In order to retrieve the session from the server side, you will need to first create a session using the FacebookCanvasLoginHelper. This class takes a signed request from Facebook supplied in a POST request, and exchanges it for a FacebookSession object. This should only really be done one when a user logs into your application:
$helper = new FacebookCanvasLoginHelper();
try {
$session = $helper->getSession();
} catch (FacebookRequestException $ex) {
// When Facebook returns an error
} catch (\Exception $ex) {
// When validation fails or other local issues
}
if ($session) {
// Store this in your PHP session somewhere:
$token = $session->getToken();
}
Thereafter, you should use the token to initialize the session:
$token = //GET THIS FROM SESSION
use Facebook\FacebookSession;
FacebookSession::setDefaultApplication('app-id', 'app-secret');
// If you already have a valid access token:
$session = new FacebookSession($token);
// To validate the session:
try {
$session->validate();
} catch (FacebookRequestException $ex) {
// Session not valid, Graph API returned an exception with the reason.
echo $ex->getMessage();
} catch (\Exception $ex) {
// Graph API returned info, but it may mismatch the current app or have expired.
echo $ex->getMessage();
}
Well, it seems you are not doing anything if session does not exists, just returning false. The problem is occuring because the session is expired/or does not exists, so you have to validate the fbToken and set the session again or create a new one.
You can create a function that checks if user is logged in, like:
function CheckFbUser() {
// Check if existing session exists
if (isset($_SESSION) && isset($_SESSION['fb_token'])) {
// Create new session from saved access_token
$session = new FacebookSession($_SESSION['fb_token']);
// Validate token
try {
if (!$session->validate()) {
$session = null;
}
} catch (Exception $e) {
// Catch any exceptions
$session = null;
}
} else {
// No session
try {
$session = $helper->getSessionFromRedirect();
} catch(FacebookRequestException $e) {
// handle it for facebook exceptions
} catch(Exception $e) {
// handle your php exceptions
}
}
// Check if a session exists
if ( isset( $session ) ) {
// Save the session
$_SESSION['fb_token'] = $session->getToken();
// Create session using saved token or the new one we generated at login
$session = new FacebookSession( $session->getToken() );
// USUALLY, here, people show the Logout Button, or anything alike, but you could it
// to return true, and then continue to run your code.
} else {
// No session
// USUALLY, here, people show the Login Button, or anything alike, you could
// use it to return false, or redirect user to login first.
$helper->getLoginUrl();
}
}
That is just an simple code, to check if user is logged in or not before you run the requests.
I get the token with the following code lines:
Bundle appActivities = new Bundle();
appActivities.putString(GoogleAuthUtil.KEY_REQUEST_VISIBLE_ACTIVITIES,
"http://schemas.google.com/AddActivity");
String serverClientID = "648976189452-46n3cl4mi4p0vasdr3u1nh87706g0bis.apps.googleusercontent.com";
String scopes = "oauth2:server:client_id:" + serverClientID
+ ":api_scope:" + Scopes.PLUS_LOGIN;
String code = null;
LTDD_1051010005 contex = new LTDD_1051010005();
try {
code = GoogleAuthUtil.getToken(contex, // Context context
plusClient.getAccountName(), // String accountName
scopes, // String scope
appActivities // Bundle bundle
);
} catch (IOException transientEx) {
// network or server error, the call is expected to succeed if you
// try again later.
// Don't attempt to call again immediately - the request is likely
// to
// fail, you'll hit quotas or back-off.
return transientEx.getMessage();
} catch (UserRecoverableAuthException e) {
// Recover
code = null;
} catch (GoogleAuthException authEx) {
// Failure. The call is not expected to ever succeed so it should
// not be
// retried.
return authEx.getMessage();
} catch (Exception e) {
throw new RuntimeException(e);
}
return code;
}
How can i post the code received to my php web server from my Android app?
How to verify that token on server and exchange to Google for access token, after that php webserver will return xml and how to andrroid can receive xml data from server immediate.
Thank you!
There's a description on how to pass tokens to your server in the Google+ sign-in documentation.
Basically, you use GoogleAuthUtil.getToken, adding the scope of your server's oauth client id.
String scopes = "oauth2:server:client_id:<SERVER-CLIENT-ID>:api_scope:<SCOPE1> <SCOPE2>";
String code = null;
try {
code = GoogleAuthUtil.getToken(context, account, scopes, null);
...
}
Then you send the received code to your server, which has to exchange it for the server's access and refresh tokens.
It is web base application.
The first page is asking for login. Once they click the login button, everything is going on with ajax.
In the ajax request,
$user = $facebook->getUser();
This is giving proper user id.
if ($user) {
try {
$fbme = $facebook->api('/me');
$user_id = $fbme['id'];
}
catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
The below line was working before.
Now it is end in the catch block. So I am not able the user details.
What could be the problem?
Since I didn't make changes in the script so far, It is suddenly stopped working.
You access token may be out of date, I suggest something like this:
try {
$data['user_profile'] = $profile = $this->facebook->api('/me');
}catch (Exception $e){
$this->facebook->setAccessToken($this->facebook->getAccessToken());
try {
if($this->facebook->getUser()) {
$this->facebook->api(array('method' =>'auth.revokeAuthorization' ));
}
}catch(Exception $e) {
redirect(...);
}
redirect(...);
}
It was a facebook bug. They fixed it last night. If you update your facebook php SDK it will work.
