I have a few applications which upload image to user profile. A few hours ago all applications were working fine but now when uploading is requested, it gives this error
Fatal error: Uncaught OAuthException: (#1) An unknown error occurred thrown in applications/fb-sdk/facebook.php on line 543
I'm using the following code to publish image.
$FILE = "images/$image";
$args = array('message' => 'My msg ');
$args['image'] = '#' . realpath($FILE);
$data = $facebook->api('/'.$uid.'/photos', 'post', $args);
Is it because of some policy change or some new feature?
I have all the permissions like upload is set to true and application takes permission to upload file.
P.s: when the application is used 2nd time, it works fine.
You need to verify if the user is logged in AND has the permissions to post on wall. We're going to do that with a TRY/CATCH with a call to the user.
$userId = $facebook -> getUser();
if ($userId) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
$userId = NULL;
error_log($e);
}
}
$app_permissions = array(
'scope' => 'publish_stream'
);
$logoutUrl = $facebook->getLogoutUrl();
$loginUrl = $facebook->getLoginUrl($app_permissions);
If the user is not logged in OR has authorized the app, you'll need to redirect him via header redirect or with a link.
if ($userId){
//Then you can call the facebook api
$data = $facebook->api('/'.$uid.'/photos', 'post', $args);
//... ...
}
That's the easiest way i've found.
EDIT : This question on stack has helped me : Facebook PHP SDK Upload Photos
No, the error is caused by the system cannot get the image file. Facebook will not allow the empty image field appear in the api. So it return Fatal error: Uncaught OAuthException: (#1) --- although it does not relate to the OAuth and OAuthException.

I try to have an app that can pause/resume my adset (accounts owned by myself).
I get no error message(or anything) output when requesting this
$adset = new AdSet($adsetid);
$adset->campaign_status = AdSet::STATUS_ACTIVE;
try{
$adset->updateSelf();
} catch (RequestException $e) {
$response = json_decode($e->getResponse()->getBody(), true);
var_dump($response);
}
But I see that the adset status did not change.
Now, I do see that the Marketing API, Settings section shows me that the API access Level is development and the app doesn't have Ads management standard access.
When I check permissions at App review > Permissions and features it shows 'Standard access' and 'ready to use'. (however not 'Active')
And at the same time my request count and error rate in the past 30 days are acceptable.
I don't understand what is missing to make it work. Can anyone help me out?
The code I have shown in my question was based on the code I copied from the Facebook marketing API documentation.
Strangely when I simulated my request using the Graph API Explorer and hit the "Get code" button it will suggest you a different code.
When I used that code instead of the code of the marketing API docs it did seem to work just as expected.
This code worked as opposed to the code from the docs:
$adsetid = "YOUR ADSET ID";
$access_token = "YOUR ACCESS TOKEN";
try {
$response = $fb->post(
'/'.$adsetid,
array (
'fields' => 'status',
'status' => 'ACTIVE'
),
$access_token
);
} catch(FacebookExceptionsFacebookResponseException $e) {
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(FacebookExceptionsFacebookSDKException $e) {
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
$graphNode = $response->getGraphNode();
I'm trying to show the feed and events of a Facebook fanpage on a website. I'm using the php sdk to call the Facebook graph api. I also created an app on my Facebook account and have an app ID, app secret and app token.
I don't want to log in the user of the website. I just want to integrate the events and news data of the Facebook fanpage on the website.
My question is: Can I use the static app token to make graph api calls with php from my server and build my website after that, so that no one will receive the app token? Or is this bad because of security issues?
Here is the code:
$app_ID = '{appID}';
$app_secret = '{appSecret}';
$app_token = "{staticAppTokenFromFacebookDeveloperSettings}";
$facebook_page_ID = '{facebookPageID}';
$fb = new Facebook\Facebook([
'app_id' => $app_ID,
'app_secret' => $app_secret,
'default_graph_version' => 'v2.7',
]);
$fb->setDefaultAccessToken($app_token);
try {
$response = $fb->get('/' . $facebook_page_ID . '/feed');
//$response = $fb->get('/' . $facebook_page_ID . '/events');
// ...
} 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;
}
Thank you very much!
You have to put the App Secret somewhere in order to use an App Access Token, and the server is the only place where it is safe. Just keep in mind that there are limits to API calls, you should cache results in your own database. Do not call the feed and events endpoints for every single user hit.
I'm using "facebook/php-sdk-v4": "dev-master".
Here is my code.
$this->helper = new Facebook\Helpers\FacebookRedirectLoginHelper('http://localhost:8000/test2');
$this->helper->getLoginUrl(['scope'=>'user_about_me,user_groups'])
//test2 controller
session_start();
$session = $this->facebook->getSessionFromRedirect();
$request = new Facebook\FacebookRequest($session, 'GET', '/me/groups/');
$response = $request->execute();
$graphObject = $response->getGraphObject();
Here is the login link:
https://www.facebook.com/v2.0/dialog/oauth?client_id=335104339978143&redirect_uri=http%3A%2F%2Flocalhost%3A8000%2Ftest2&state=0d09d4965509ccb3dc78f2fffc44c11e&sdk=php-sdk-4.1.0-wip&scope=user_about_me%2C+user_groups
When I use the fb account that I registered the app, I can get the groups and the permission on login popups. But when I use other facebook accounts, the permission does not popup and I get no result.
You are asking for additional permissions in the incorrect way. You need to do the following using Facebook PHP SDK v4.0.9:
// generate login url with scope, each permission as element in array
$loginUrl = $helper->getLoginUrl( array( 'email', 'user_friends' ) );
// output login link
echo 'Login';

In my javascript I have a click event that triggers an ajax call to the php page where I send my notification from. I chose to do it this way because the documentation advises against using your app secret in any client side code, and the notifications parameters requires an access token that you can only get using the app secret.
The problem I'm having is that even though I'm logged in, $facebook->getUser() is returning 0 in php, so the api call I make afterwards to send the notification wont work. My user is already logged in via the client side code, so how do I get the message to the php that they're logged in so the notification can be sent.
//JS
$.ajax({
url : "http://xxxxxo/bn/notification.php",
type : 'POST',
data: {notify: notify },
success : function (result) {
console.log(result);
},
error : function () {
alert("error sending notification");
}
});//closes ajax
//PHP
<?php
require_once(dirname(__FILE__).'/php-sdk/facebook.php') ;
$APPLICATION_ID = '1402xxxxx7';
$APPLICATION_SECRET = 'ce71d6bbxxxxx5f55a';
$fb_app_url = "http://apps.facebook.com/myAPP";
$config = array();
$config['appId'] = $APP_ID;
$config['secret'] = $APP_SECRET;
$config['cookie'] = true;
$facebook = new Facebook($config) or die('Error is here!');
$facebook = new Facebook(array(
'appId' => $APP_ID,
'secret' => $APP_SECRET,
'fileUpload' => true
));
$notify = $_REQUEST['notify'];
$userid = $facebook->getUser();
/*IF WE HAVE A LOGGED IN USER AND THE 'NOTIFY' REQUEST VALUE, THEN SEND THE NOTIFICATION.
BUT MY USER ID IS 0. HOW DO I GET PHP TO RECOGNIZE ME AS LOGGED IN WITHOUT HAVING TO FORCE MY USER TO LOG IN VIA PHP AFTER THEY'VE ALREADY LOGGED IN CLIENT SIDE?*/
if($userid && $notify){
$token_url ="https://graph.facebook.com/oauth/access_token?" .
"client_id=" . $APP_ID .
"&client_secret=" . $APP_SECRET .
"&grant_type=client_credentials";
$app_token = file_get_contents($token_url);
$app_token = str_replace("access_token=", "", $app_token);
$data = array(
'href'=> 'https://apps.facebook.com/thebringernetwork/',
'access_token'=> $app_token,
'template'=> 'test'
);
$sendnotification = $facebook->api('/1622649653/notifications', 'post', $data);
}else{
//handle error
}
?>
The first thing I noticed is that you define your app id as $APPLICATION_ID but use it as $APP_ID (and the same goes for your app secret). But since you didn't mention any errors and $facebook->getUser(); executes I'm guessing this is just a bad copy-paste.
Now for the sake of answering this question I'm going to presume that you are using the latest versions of both JS and PHP SDKs. These use oauth 2.0 and change the way you pass the login information from JS to PHP.
According to Facebook Developer Blog removing $config['cookie'] = true; and setting oauth to true in your JS configuration should work. Just make sure to refresh the site after the login.
The solution I've found in my own project is to disable cookies altogether and simply pass the access token to my PHP script.
In your JS call your PHP script like this (make sure to call this after the JS login!):
$.ajax({
url : "http://xxxxxo/bn/notification.php",
type : 'POST',
data: {
notify: notify,
token: FB.getAuthResponse()['accessToken'] // add your access token
},
success : function (result) {
console.log(result);
},
error : function () {
alert("error sending notification");
}
});
And in your PHP script add this after creating the FB object.
$facebook->setAccessToken($_POST['token']); // set the users access token
Doing things this way will also get rid of any need to refresh the website after the login.
Yes, this is a common problem when using the PHP SDK in combination with AJAX:
When you make an AJAX request, the PHP SDK deletes the cookies where the authorization information are stored, and then the next call to getUser will just return 0, because this method tries to find the current user id in those cookies – apparently there is something in the OAuth 2.0 spec that demands this behavior to prevent some sort of click-jacking attack.
But the info will still be stored in the session, so you can read the user id (and the user access token, should you need it) from there:
$user_id = $_SESSION['fb_YourAppIdHere_user_id'];
$user_access_token = $_SESSION['fb_YourAppIdHere_access_token'];
Replace YourAppIdHere with your app id (so it becomes fb_1234567890_user_id resp. fb_1234567890_access_token) to get the correct names of those session keys.
I have built an app using the PHP Facebook SDK. It allows users to authenticate my app with facebook OAth so that they can update their status' via my App. This works great, however a lot of my users have business pages and they want to update the status on their business page not their main personal feed. How is this possible? Below is what I have so far.
if ($status != ''){
try {
$parameters = array(
'message' => "$status"/*,
'picture' => $_POST['picture'],
'link' => $_POST['link'],
'name' => $_POST['name'],
'caption' => $_POST['caption'],
'description' => $_POST['description']*/
);
//add the access token to it
$parameters['access_token'] = $access_token;
//build and call our Graph API request
$newpost = $facebook->api(
'/me/feed',
'POST',
$parameters
);
$success['status'] = "$xml->status";
$xml2 = new XMLGenerator($success, 'facebook','status');
$returnData = $xml2->output;
$returnData = APIResponse::successResponse('200', "$xml->status");
} catch (Exception $e) {
$returnData = APIResponse::errorResponse('400', 'Facebook Error: '.$e);
}
I assume I would have to change '/me/feed'? but to what? What is they have multiple pages how would my app know which page to post to?
Any help with this would be much appreciated.
You can substitute me with the PAGE_ID to post to a page e.g., /013857894/feed. Make sure that you have completed the OAuth process with the manage_pages and publish_stream permissions. You can learn more at the link below:
https://developers.facebook.com/docs/reference/api/page/#statuses
If the user has multiple Pages then you will first need to give them some way of selecting which page they want to post to. You can find out which Facebook Pages a given user is the administrator of by calling /me/accounts for that user. You can find out more about this approach in the Connections section of this page:
https://developers.facebook.com/docs/reference/api/user/
