I use graph v2.10, php sdk 5.5 I try to post on user album if is founded, but my script display an error:
Graph return an error. Permission error.
When an user try to login to my website, user give permissions publish_actions, email, user_photos to app. But graph say permission error.
$albums = $fb->get('/me/albums', $_SESSION['facebook_access_token'])->getGraphEdge()->asArray();
$album = array();
foreach($albums as $k=>$v) {
if($fetch_api['album_name'] == $v['name']) {
$album[$fetch_api['album_name']] = $v['id'] ;
}
}
if(count($album > 0)) {
$data = [
'message' => $_POST['msg'],
'source' => $fb->fileToUpload('images/gallery-img1.jpg'),
];
try {
// Returns a `Facebook\FacebookResponse` object
$response = $fb->post('/'.$album[$fetch_api['album_name']].'/photos', $data, $_SESSION['facebook_access_token']);
} catch(Facebook\Exceptions\FacebookResponseException $e) {
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
echo 'Facebook SDK returned an error: ' . $e->getMessage();

Following at the Facebook API docs I'm able to return only 4 attributes from my FB app.
My Code:
$user = Auth::user();
try {
$response = $this->facebook->get('/'.$user->facebook_app_id, $user->facebook_access_token);
} catch(Facebook\Exceptions\FacebookResponseException $e) {
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
$graphNode = $response->getGraphNode();
dd($graphNode);
This only returns 4 attributes
I need it to also return app_domains. Looking at the docs it looks like it should? Is there a way to return the app_domains array from a FB app? FB app API
Looks like you'll need to use something like this:
$response = $this->facebook->get('/'.$user->facebook_app_id,
['fields' => 'app_domains'],
$user->facebook_access_token
);
With the new feature of connecting pages with groups (https://grytics.com/blog/link-facebook-groups-pages/) I tought, that it would be possible to post as page on group feed via Graph API. All my tries ended up with errors saying:

I am new to the fb api, and I am not a english native speaker, so maybe someone is able to clearify that situation?
Thank you!
[EDIT 1]
Added code. Hint: When I change PAGE_TOKEN to USER_TOKEN it works.
[EDIT 2]
Full Code added.
I found a user comment in the FB Group Facebook Developer Community from August:
And no, there is no build-in way to have page posts show up in a group
automatically.
I would like to ask a facebook timeline and photo gallery, but the access token is null.
$this->FaceBookApp = new Facebook\Facebook(array(
"app_id" => $this->appID,
"app_secret" => $this->appSecret,
"default_graph_version" => "v2.5"
));
$helper = $this->FaceBookApp->getRedirectLoginHelper();
$permissions = array('user_posts');
$loginUrl = $helper->getLoginUrl( _WEBPAGE .'/facebook-sdk/printAccessToken.php', $permissions);
echo "<script>window.top.location.href='".$loginUrl."'</script>";
callback php:
$helper = $this->FaceBookApp->getCanvasHelper();
try {
$accessToken = $helper->getAccessToken();
} catch(Facebook\Exceptions\FacebookResponseException $e) {
// When Graph returns an error
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
// When validation fails or other local issues
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
var_dump($accessToken);
when i try without access token, the
$response = $this->FaceBookApp->get('/'.$userId.'/feed', $this->appID .'|'. $this->appSecret);
var_dump( $response->getDecodedBody() );
is empty array.
Please, help me.
I have successfully uploaded picture to facebook using Graph API v5.
But how do i make it default profile picture ?
Following is my upload() function:
//Upload image
function upload($path,$token,$fb)
{
$image = [
'message' => 'My awesome photo upload example.',
'source' => $fb->fileToUpload($path), // $fb is instance
];
try {
// Returns a `Facebook\FacebookResponse` object
$response = $fb->post('/me/photos', $image, $token);
} catch(Facebook\Exceptions\FacebookResponseException $e) {
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
$graphNode = $response->getGraphNode();
debug_to_console($graphNode);
echo " \n Photo ID: " . $graphNode['id'];
}

I am new to the whole Facebook API.
I am creating a login page for users, and the idea is that they login with Facebook.
At the top of login page I have the following code:
$fb = new Facebook\Facebook([
'app_id' => "$fb_appid",
'app_secret' => "$fb_appsecret",
'default_graph_version' => 'v2.2',
]);
Then a little lower I have the login button:
if(isset($fb)){
$helper = $fb->getRedirectLoginHelper();
$permissions = ['email']; // optional
$fb_login_url = $helper->getLoginUrl("$server_url/public/facebook/login-callback", $permissions);
} else $fb_login_url = "";
if(strlen($fb_login_url) >= 1) echo "<a href='$fb_login_url'><i class='fa fa-2x fa-facebook-square'></i></a>";
else echo "<a href='#' disabled='disabled'><i class='fa fa-2x fa-facebook-square'></i></a>";
The code works up until there, if I click the button, I go through to the Facebook portal, click the allow for the permissions and whatever, then it redirects me to login-callback.
The code on login-callback is:
if(isset($fb)){
$helper = $fb->getRedirectLoginHelper();
try {
$accessToken = $helper->getAccessToken();
} catch(Facebook\Exceptions\FacebookResponseException $e) {
$err_message = 'Graph returned an error: ' . $e->getMessage();
access_log("facebook_login","IP:$client_ip\r\nFacebook Error: $err_message");
} catch(Facebook\Exceptions\FacebookSDKException $e) {
$err_message = 'Facebook SDK returned an error: ' . $e->getMessage();
access_log("facebook_login","IP:$client_ip\r\nFacebook Error: $err_message");
}
if (strlen($err_message) <= 0 && isset($accessToken)) {
$_SESSION['facebook_access_token'] = (string) $accessToken;
$fb->setDefaultAccessToken("$accessToken");
try {
$response = $fb->get('/me');
$userNode = $response->getGraphUser();
// $username = $userNode->getName();
// $firstname = $userNode->getFirstName();
// $lastname = $userNode->getLastName();
print_r($userNode);
} catch(Facebook\Exceptions\FacebookResponseException $e) {
$err_message = 'Graph returned an error: ' . $e->getMessage();
access_log("facebook_login","IP:$client_ip\r\nFacebook Error: $err_message");
} catch(Facebook\Exceptions\FacebookSDKException $e) {
$err_message = 'Facebook SDK returned an error: ' . $e->getMessage();
access_log("facebook_login","IP:$client_ip\r\nFacebook Error: $err_message");
}
}
}
The $userNode looks like this:
Facebook\GraphNodes\GraphUser Object
(
[items:protected] => Array
(
[name] => Jacques Koekemoer
[id] => xxxxxxxxxxxxxxxxxx
)
)
I have set the permissions to allow for the email, and if I am not mistaken the public profile is sent automatically.
I have also checked that the button on the login page does have "&scope=email". Below is the code that I have right on the page right now in the login button:
https://www.facebook.com/v2.2/dialog/oauth?client_id=xxxxxxxx&state=xxxxxxxx&response_type=code&sdk=php-sdk-5.0.0&redirect_uri=http%3A%2F%2Fxxxxxxx.xxxxxxxxxxxx.co.za%2Fpublic%2Ffacebook%2Flogin-callback&scope=email
I replaced the client_id, state and domain name because I don't want that information available publicly as I don't know what people can do with it.
Let me know if it is needed to solve the problem.
I used the Facebook guide here to setup and download the SDK.
I solved the problem.
You need to request specific fields from Facebook in the get function.
$response = $fb->get('/me?fields=id,name,email');
This can be found here.
A full list of fields that you can query can be found here.
Example
if (isset($fb)) {
$helper = $fb->getRedirectLoginHelper();
try {
$accessToken = $helper->getAccessToken();
} catch (Facebook\Exceptions\FacebookResponseException $e) {
$err_message = 'Graph returned an error: ' . $e->getMessage();
access_log("facebook_login", "IP:$client_ip\r\nFacebook Error: $err_message");
} catch (Facebook\Exceptions\FacebookSDKException $e) {
$err_message = 'Facebook SDK returned an error: ' . $e->getMessage();
access_log("facebook_login", "IP:$client_ip\r\nFacebook Error: $err_message");
}
if (strlen($err_message) <= 0 && isset($accessToken)) {
$_SESSION['facebook_access_token'] = (string)$accessToken;
$fb->setDefaultAccessToken("$accessToken");
try {
// this here is where you specify the fields
$response = $fb->get('/me?fields=id,name,email');
$userNode = $response->getGraphUser();
/* handle the result */
} catch (Facebook\Exceptions\FacebookResponseException $e) {
$err_message = 'Graph returned an error: ' . $e->getMessage();
access_log("facebook_login", "IP:$client_ip\r\nFacebook Error: $err_message");
} catch (Facebook\Exceptions\FacebookSDKException $e) {
$err_message = 'Facebook SDK returned an error: ' . $e->getMessage();
access_log("facebook_login", "IP:$client_ip\r\nFacebook Error: $err_message");
}
}
}
One of the my friend was trying to the issue from last 5 days. huummm very irritating. which got love in 2 min...
Assumption: using PHP for O2Authentication
Solution:
$loginURL = $fb->getLoginUrl({your redirect URL},['email']);
And job is done.
Thanks & Regards

Check you app version if it is version 2.2 or lower, it will work fine , it is not than it will not return. for that you have to request api with scope for email access.
