I want to use facebook graph api to get the event details of a specific page.But I keep getting a blank page back.
<?php
error_reporting(E_ALL);
require 'vendor/autoload.php';
use Facebook\FacebookSession;
use Facebook\FacebookRequest;
class HomeController extends BaseController {
public function index()
{
FacebookSession::setDefaultApplication('APP_ID', 'APP_SECRET');
$session = FacebookSession::newAppSession();
/* make the API call */
$request = new FacebookRequest(
$session,
'GET',
'/1531904510362357/'
);
$response = $request->execute();
$graphObject = $response->getGraphObject();
dd($graphObject);
}
$session should = new FacebookSession('accesstoken')
Another thing I've learned is that the new api (v2.0+) is very very strict on what is displayed. For example, you can no longer open up someones feed that doesn't also have an access token to your application.
I would go back and read on the permissions and make sure that the correct permissions are set and validated for your application.

I have a script that can obtain successfully from the Facebook oAuth API:
function getToken() {
var appId = "XXXXXX";
var clientSecret = "XXXXXXXXXXXX";
var url = "https://graph.facebook.com/oauth/access_token?client_id="+appId+"&client_secret="+clientSecret+"&grant_type=client_credentials";
var response = UrlFetchApp.fetch(url);
var queryResult = response.getContentText();
var token = queryResult.slice(13);
return(token);
}
The question is, that I prefer not to have my appId and clientSecret in the body of my script so is there a way where I can code this in without having my credentials in plain text?
Manually enter the keys and secret into the script editor as a "Script Property" (File > Project properties > Script properties) and then access them in the code using the Properties Service.
For example you could manually add:
property:APP_ID, value:'XXXXXXXX'
Then access it in the code with
var appId = PropertiesService.getScriptProperties().getProperty('APP_ID')
This technique works if you wanted to share the script on somewhere like Github, or if you only gave out view-access to the script in which case the script properties aren't visible (you should not be able to see the SPs in this script). If you give edit access to others they'll be able to see the SPs, but then you could use User Properties.
For that you need to install latest facebook SDK which uses Namespace and protected methods to get facebook data using graph api. Below is an example I worked on :
require_once ROOT . '/vendor/Facebook/autoload.php';
use Facebook\FacebookSession;
use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookResponse;
use Facebook\FacebookSDKException;
use Facebook\FacebookRequestException;
use Facebook\FacebookAuthorizationException;
use Facebook\GraphObject;
use Facebook\Entities\AccessToken;
use Facebook\HttpClients\FacebookCurlHttpClient;
use Facebook\HttpClients\FacebookHttpable;
class FacebookComponent extends Component
{
public $app_id;
public $app_secret;
public $default_graph_version;
public function __construct()
{
$this->app_id = "XXXXXXXXXXXXXXX";
$this->app_secret = "XXXXXXXXXXXXXXXXXXXXX";
$this->default_graph_version = "v2.5"; // For Offerz-develop app
}
public function getFacebookConn(){
$app_id = $this->app_id;
$app_secret = $this->app_secret;
$fb = new \Facebook\Facebook([
'app_id' => $app_id,
'app_secret' => $app_secret,
'default_graph_version' => 'v2.5',
]);
return $fb;
}
}
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

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 want to store some information in the local browser cookie. After hours looking for a nice tutorial, I managed to store some data in a non-session cookie:
controller - indexAction()
$cookieGuest = array(
'name' => 'mycookie',
'value' => 'testval',
'path' => $this->generateUrl('my_route'),
'time' => time() + 3600 * 24 * 7
);
$cookie = new Cookie($cookieGuest['name'], $cookieGuest['value'], $cookieGuest['time'], $cookieGuest['path']);
$response = new Response();
$response->headers->setCookie($cookie);
$response->send();
I wonder if this is the correct way. Furthermore I tried several ways to read the cookie with the HttpFoundation Component, but without success. Is there another way than accessing the cookie via $_COOKIE['mycookie'] ?
Here is where I try to read the cookie
controller - cookieAction()
public function cookieAction($_locale, $branch, $page)
{
$response = new Response();
$cookies = $response->headers->getCookies();
var_dump($cookies);
// TODO: Get params for indexAction from cookie if available
return $this->indexAction($_locale, $branch, $page);
}
This is the correct way of setting cookie.
To read cookie already written in the browser do:
$request->cookies->get('myCookie');
But after I created cookie in the $response object:
$cookie = new Cookie('myCookie', 'contentOfMyCookie');
$response = new Response();
$response->headers->setCookie($cookie);
I call this method:
$response->headers->getCookies();
I get an array of cookies, which are to be written in the browser - not those already existing there.
Figuratively, between $request and $response there is a time of executing controller's code.
Besides, in a twig template you can use
{{ app.request.cookies.get('myCookie') }}
you thus get value of the cookie already written in the browser, not that from the $response object! Newly created cookie from the browser you can read only after having reloaded page (ajax doesn't need to reload whole page).
To sum it up, you can read cookies using $request object, and create them with $response object. (Obviously, for some reasons, you can also read $response object cookies - but these are rather rare situations).
$response->headers->getCookies();
should return an array of cookies look in ResponseHeaderBag class for more information about that function
this can be useful for someone trying to make cookies in symfony2 :
use Symfony\Component\HttpFoundation\Cookie;
Example how to use Cookies and Session:
<?php
namespace AppBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Cookie;
use Symfony\Component\HttpFoundation\Response;
class DefaultController extends Controller
{
public function indexAction()
{
// Set session value
$session = $this->getRequest()->getSession();
$session->set('test', 1);
// Get session value
$value = $session->get('test');
// Set cookie value
$response = new Response();
$cookie = new Cookie('test', 1, time()+3600);
$response->headers->setCookie($cookie);
// Get cookie value
$this->getRequest()->cookies->get('test');
}
}
use Symfony\Component\HttpFoundation\Cookie;
use Symfony\Component\HttpFoundation\Response;
// set current active tab in cookie
$cookie = new Cookie('myProfileActiveTab', 'myaddress', strtotime('now + 60 minutes'));
$response = new Response();
$response->headers->setCookie($cookie);
$response->send();
// get current active tab from cookies
$cookies = $request->cookies;
if ($cookies->has('myProfileActiveTab')) {
$activetab = $cookies->get('myProfileActiveTab');
}
