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';

What I am actually trying to do is to retrieve my posts/statuses from my personal facebook profile page (this is not a fan page) and display them in my website. Also please note that every user that will visit my website should be able to view my statuses by means it does not have to do with authenticating them or something like that. This is something that needs to be generated server-side.
I am aware that you can retrieve a JSON string from a URL like this https://graph.facebook.com/MY_PROFILE_ID/feed?access_token=ACCESS_TOKEN because I tried it from the facebook developers (Graph API Explorer) page and it is exactly what I need.
The thing is that when I generate the access token from the Graph API Explorer I can select permissions and it generates the token respectively according to permissions chosen, such as user_status, status_update, etc.
Now I want to accomplish this by using PHP-SDK but I have no idea how to generate an access token the same as the one I generate in the Graph API Explorer.
The basic way to do this is by calling getAccessToken() as shown here. The thing is that when I use the token generated from this simple method the JSON string returned will only show me my basic information.
$config = array(
'appId' => 'MY_APP_ID',
'secret' => 'MY_APP_SECRET',
);
$facebook = new Facebook($config);
$ACCESS_TOKEN = $facebook->getAccessToken();
How can I add permissions for instance? Should I assign parameters somewhere? I spent quite a lot of time reading the facebook API documentation and some other forums but I did not find the answer that I need.
Finally if I get the right access token than I would simply retrieve the JSON string and parse it with what I need.
Thanks.
you need for add permissions in your code for login using the fb js sdk add in the scope this like this example:
$("#login").on('click',function(){
FB.login(function(response){
console.log(response);
},{scope: 'email,manage_pages,read_insights'});
});
or in php fb sdk the next form:
<?php
require 'server/fb-php-sdk/facebook.php';
$app_id = 'APP_ID';
$app_secret = 'APP_SECRET';
$app_namespace = 'APP_NAMESPACE';
$app_url = 'https://apps.facebook.com/' . $app_namespace . '/';
$scope = 'email,publish_actions';
// Init the Facebook SDK
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
));
// Get the current user
$user = $facebook->getUser();
// If the user has not installed the app, redirect them to the Login Dialog
if (!$user) {
$loginUrl = $facebook->getLoginUrl(array(
'scope' => $scope,
'redirect_uri' => $app_url,
));
print('<script> top.location.href=\'' . $loginUrl . '\'</script>');
}
?>
the most important for add permission is this part :
$scope = 'email,publish_actions';
you can find all about the extended permissions in this link
https://developers.facebook.com/docs/reference/login/extended-permissions
Is there any way I can get access token of any page by page id, I should be able to post on page behalf of admin?
I'm guessing you don't want to be admin of your clients' pages:
You could create a page so that your clients login to Facebook and
grant permissions to your app.
Then you can get the page access token and save it in your DB.
Finally use that access token to post directly to each page as
admin without being you the actual admin.
Quoting Facebook documentation:
To obtain a page access token you need to start by obtaining a user
access token and asking for the manage_pages permission. Once you have
the user access token you then get the page access token via the Graph
API.
To get user access token (supposing you are logged in to fbk and have granted permissions to your App):
$user = $facebook->getUser();
if(!$user) {
$login_url_params = array(
'scope' => 'publish_stream,read_stream,manage_pages',
'fbconnect' => 1,
'redirect_uri' => 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']
);
$login_url = $facebook->getLoginUrl($login_url_params);
//redirect to the login URL on facebook
header("Location: {$login_url}");
}
Don't forget get to a time extended access token
$facebook->setExtendedAccessToken();
$access_token = $facebook->getAccessToken();
With that token you can get the page token via the API:
$accounts = $facebook->api(
'/me/accounts',
'GET',
array(
'access_token' => $access_token
)
);
$accounts will be an associative array with all the info of the pages you admin (including the tokens for each page). To get the token of an specific page knowing its ID:
$accounts = $accounts['data'];
foreach($accounts as $account){
if( $account['id'] == $pagId ){
//$pagId would be the ID of the page you want to use
//This is the token of the page with the ID $pagId
$page_access_token = $account['access_token'],
}
}
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/
I am trying to find a way to keep connected with the Facebook API once authorised using OAuth but am having problems. I dont want the users of my App to have to login via Facebook every time they want to use my app.
I store the oauth access toekn in a database after the user authenticates with facebook and I have "offline_access" permissions set, so in theory, this should be possible.
However, I get "Uncaught OAuthException: An active access token must be used to query information about the current user." when trying to connect to Facebook API using a saved Oauth token stored in a database.

Facebook pass an expires field when it pass your application the access token and default as per the Facebook is 2hours.
there are other factors why which a access_token can expire and here are the complete details for you
Ankur Pansari
How-To: Handle expired access tokens
Now next we can talk about offline_access which means
It Enables your app to perform authorized requests
on behalf of the user at any time. By default,
most access tokens expire after a short time period to ensure applications
only make requests on behalf of the user when the are actively
using the application. This permission makes the
access token returned by our OAuth endpoint long-lived.
So it all means you have to make sure you always using valid access_token.For details about various permission here is a reference link
