Please help me get group list from facebook api.
When I use this code:
$token = $facebook->getAccessToken();
$groups = $facebook->api('/me/groups','GET', array('access_token' => $token));
It returns empty array.
Or if I cut the access token off it still doesn't work.
But when I call the graph api with:
https://graph.facebook.com/me/groups?access_token=....
It returns all of groups, and when I use:
$groups = file_get_contents('https://graph.facebook.com/me/groups?access_token='.$token);
It returns empty json too.
How do I solve it?
I believe that you need to add user_groups permission in order to get the result.
When you facebook login:
FB.login(function(response) {
if (response.authResponse) {
...
} else {
....
}
}, {scope: 'user_groups'});
EDIT:
With using Facebook PHP SDK:
$loginUrl = $facebook->getLoginUrl(array('scope' => 'user_groups'));

I'm currently trying to pull the list of company pages a user is the admin of with the LinkedIn API and am getting the following response:
Array
(
[response] => {
"errorCode": 0,
"message": "Member does not have permission to get companies as admin.",
"requestId": "R1LHP32UKD",
"status": 403,
"timestamp": 1482357250945
}
[http_code] => 403
)
The call works perfectly when authenticated as the same user in the LinkedIn API Console.
Has anyone else come across this?
I figured out the problem.
Even though I had made sure the app had the rw_company_admin permission checked off, I wasn't passing that in the scope when requesting oath2 authorization.
My fixed code below:
The call:
return $linkedin->getAuthorizationUrl("r_basicprofile w_share rw_company_admin", $thisurl);
The function:
public function getAuthorizationUrl($scope, $callback)
{
$params = array('response_type' => 'code',
'client_id' => $this->api_key,
'scope' => $scope,
'state' => uniqid('', true), // unique long string
'redirect_uri' => $callback,
);
// Authentication request
$url = 'https://www.linkedin.com/uas/oauth2/authorization?' . http_build_query($params);
// Needed to identify request when it returns to us
$_SESSION['Linkedin_state'] = $params['state'];
$_SESSION['Linkedin_callback'] = $callback;
// this is where to send the user
return $url;
}
First you have to get user token of linkedin user
Use Socialite or REST API package for oauth.
Once you having user token it is pretty simple to fetch Company list under admin user
$token = 'uflefjefheilhfbwrfliehbwfeklfw'; // user token
$api_url = "https://api.linkedin.com/v1/companies?oauth2_access_token=".$token."&format=json&is-company-admin=true";
$pages = json_decode(file_get_contents($api_url));
You have get $pages json array of list of company profile.
I made link of facebook login which requests an access token with permission to friends list:
<a href="https://www.facebook.com/dialog/oauth?response_type=token&scope=user_friends...>Login</a>
After the user passed the login successfully and accept these permissions and my app stored the access token, I tried to get his friends list by:
https://graph.facebook.com/me/friends?access_token={ACCESS_TOKEN}
But all I get is:
{
"data": [
],
"summary": {
"total_count": 245
}
}
Maybe I should request something else in the scope?
Thank you !
$request = new FacebookRequest(
$session,
'GET',
'/me/friends'
);
$response = $request->execute();
$graphObject = $response->getGraphObject();
For example in CodeIgniter I use fb library and i get friends list like this:
public function get_user_friends() {
if ( $this->session ) {
try {
$fr = new FacebookRequest( $this->session, 'GET', '/me/friends' );
$request = $fr->execute();
$user_friends = $request->getGraphObject()->asArray();
return $user_friends;
} catch(FacebookRequestException $e) {
return false;
/*echo "Exception occured, code: " . $e->getCode();
echo " with message: " . $e->getMessage();*/
}
}
}
And dont forget that it has some conditions:
Permissions
A user access token with user_friends permission is required to view the current person's friends.
This will only return any friends who have used (via Facebook Login) the app making the request.
If a friend of the person declines the user_friends permission, that friend will not show up in the friend list for this person.

I am trying to get a page access token starting out with just a users access token stored in my database and a page id. So far I have not been using the facebook.php instead just using php's curl_* functions. So far I can send posts to the page (with a hard coded page id) but I want to impersonate the page when doing so.
Can I do this easily without facebook.php, that would be nice as it might save me from feeling like I should rewrite what I've done so far. If not, then how would I get the page access token from the facebook object - remember so far at least I don't store user ids or page ids in my db, just user access tokens and of course my app id and secret.
I've been looking at the example for getting page access tokens but I find it not quite what I need as it gets a user object and in so doing seems to force the user to login to facebook each time, but I stored the user access token to avoid exactly that from happening.
Do I need more permissions than manage_page and publish_stream? I tried adding offline_access but it doesn't seem available anymore (roadmap mentions this).
here is some of my code from my most recent attempt which uses the facebook.php file:
// try using facebook.php
require_once 'src/facebook.php';
// Create our Application instance
$facebook = new Facebook(array(
'appId' => $FB_APP_ID, // $FB_APP_ID hardcoded earlier
'secret' => $FB_APP_SECRET, // $FB_APP_SECRET hardcoded earlier
));
$facebook->setAccessToken($FB_ACCESS_TOKEN );
//got user access token $FB_ACCESS_TOKEN from database
// Get User ID -- why?
$user = $facebook->getUser();
//------ get PAGE access token
$attachment_1 = array(
'access_token' => $FB_ACCESS_TOKEN
);
$result = $facebook->api("/me/accounts", $attachment_1);
foreach($result["data"] as $page) {
if($page["id"] == $page_id) {// $page_id hardcoded earlier
$page_access_token = $page["access_token"];
break;
}
}
echo '<br/>'.__FILE__.' '.__FUNCTION__.' '.__LINE__.' $result= ' ;
var_dump($result); //this prints: array(1) { ["data"]=> array(0) { } }
$facebook->setAccessToken($page_access_token );
// Get User ID, why - re-init with new token maybe?
$user = $facebook->getUser();
//------ write to page wall
try {
$attachment = array(
'access_token' => $page_access_token,
'link' => $postLink,
'message'=> $postMessage
);
$result = $facebook->api('/me/feed','POST', $attachment);
echo '<br/>'.__FILE__.' '.__FUNCTION__.' '.__LINE__.' $result= ' ;
var_dump($result);
} catch(Exception $e) {
echo '<br/>'.__FILE__.' '.__FUNCTION__.' '.__LINE__.' $e= ' ;
var_dump($e); /*this gives : "An active access token must
be used to query information about the
current user." */
}
die;
Thanks
PS: I hardcoded the user id and started calling
$result = $facebook->api("/$user_id/accounts", $attachment_1);
and I still get an empty result.
PPS: The Graph API Explorer does not show my fan pages either even though my account is set as the Manager. My attempts to post work but show as being from my account rather than from the page.
PPPS: made a little progress by adding permissions on the graph explorer page to get an access token that way but that doesn't help as I need to the the access token programmatically. When a user with many fan pages logs in to my site I want to show them the list of their facebook fan pages to choose from. In practice aren't the permissions just granted on the app?
PPPPS: the list of permissions on my app now stands at : email, user_about_me, publish_actions
and
Extended Permissions:
manage_pages, publish_stream, create_note, status_update, share_item
do I need more? when I try now I still fail to get anything from the call to:
$facebook->api("/$user_id/accounts", $attachment_1);
Px5S: DOH!!! I see now that I was neglecting to add the manage_pages permissions to my call for a user access token when my scripts first get one and store it in the DB. But when I reuse that new access token I still get the error : "An active access token must be used to query information about the current user." So, can't such tokens be reused? Aren't they long term? will read more stuff...
Here is my functioning code, still messy but seems to work, note the scopes on the first $dialog_url, and please feel free to mock my code or even suggest improvements :

$code = $_REQUEST["code"];
$FB_ACCESS_TOKEN = getFaceBookAccessToken( );
$FB_ACCESS_TOKEN_OLD = $FB_ACCESS_TOKEN;
//if no code ot facebook access token get one
if( empty($code) && empty($FB_ACCESS_TOKEN) && $_REQUEST["returnurl"] != '1')
{
// if( $_REQUEST["returnurl"] == '1') die;

setFaceBookAccessToken( $FB_ACCESS_TOKEN);
}
$_SESSION['FB_ACCESS_TOKEN'] = $FB_ACCESS_TOKEN;
$page_name = '';
$page_id = getFaceBookPageId(); //from db
if(empty($page_id ) ) return null;
//in case there are multiple page_ids separated by commas
if(stripos($page_id, ',') !== false ){
$page_ids = explode(',', $page_id) ;// = substr($page_id, 0, stripos($page_id, ','));
}
$result = null;
foreach($page_ids as $page_id){
$page_id = trim($page_id);
if( !empty($FB_ACCESS_TOKEN)){
//get page_id

Now, I wonder if I can send the same message to several pages at once ...
Yup, just by looping over the ids, see above, it now supports multiple page ids.
And unless someone wants to contribute to the code - there's lots of ways it can be improved - I'm done.
I developed Facebook application and I have some problems on "Allow access step",In initial stage user must authorize app and permissions.Currently if users skip extended permissions also landing to application home page , But I need to force user to accept all permissions, I got success when using FQL method , Now its not working , I cant find out the solution. Here is my code
$TotalPermissions = UserAndFriendsPermissions();
return true;
$tp = substr_replace($TotalPermissions ,"",-1);
$this->loadClassFile("Facebook", MAIN_PLUGIN_PATH."Common/facebook/facebook.php");
$facebook = new Facebook(array('appId' => $FBConnect["fb_app_id"],'secret' => $FBConnect["fb_secret_key"],));
$params = array('method' => 'fql.query','query' => "SELECT ".$tp." FROM permissions WHERE uid=me()");
$result = $facebook->api($params);
$totalp = count(explode(",",$tp));
$ap=0;
foreach ($result[0] as $key => $val)
{
if($val==1)
{
$ap++;
}
}
if($ap==$totalp)
{
return true;
}
else
{
?>
<?php
Redirect("https://apps.facebook.com/APP_NAMESPACE");
}
You cannot force users to accept all your extended permissions. What you can do is to check for permissions given and handle those cases accordingly i.e. redirecting users who have not given permission to a landing page which explains why you need those permissions.
I want to get user access token because I need to get user's posts and comments.
When I use Graph API Explorer, the access token it generates is correct one and shows me my posts and comments and some other data. But when try to get posts and comments by using this code than it does not return me posts and comments and return some other data only which i don't need.
require_once('facebook.php');
$config = array(
'appId' => '383128895071077',
'secret' => '6a9ab479186f53db5c531a3fa5f91be0',
);
$facebook = new Facebook($config);
$access_token = $facebook->getAccessToken();
$result = $facebook->api('/me/feed/', array('access_token' => $access_token));
I searched all the google and get access token by different ways but I could not get posts and comments of me. I must be doing something wrong and need to sort out this as soon as possible.
Thanks in advance.
You should check this example
Facebook php sdk example
you should check whether we have user access token like this
// Get User ID
$user = $facebook->getUser();
// We may or may not have this data based on whether the user is logged in.
//
// If we have a $user id here, it means we know the user is logged into
// Facebook, but we don't know if the access token is valid. An access
// token is invalid if the user logged out of Facebook.
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
// Login or logout url will be needed depending on current user state.
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
$loginUrl = $facebook->getLoginUrl();
}
Once we get the user details, you can ensure that user is logged into app and authorized the app.
For feeds
You should have extended permissions read_stream
then you can read the wall feed.
