Im using Facebook's PHP sdk for the first time in a clients site and I'm a little confused. I'm trying to get some data from the clients facebook page and inject it into their site. One of the objects I am trying to get is a list of the clients photo albums for a photo gallery.
<?php
$albums = $Facebook->api("/169639127532/albums?fields=id,name,cover_photo");
$photos = array();
$queries = array();
foreach($albums['data'] as $album) {
if(array_key_exists("cover_photo", $album))
$queries[] = array("method" => "GET", "relative_url" => "/".$album['cover_photo']."?fields=source");
}
$rawPhotos = $Facebook->api('?batch='.json_encode($queries), 'POST');
foreach($rawPhotos as $photo) {
//print_r(json_decode($photo['body'])); echo "<br /><br />";
$photo = json_decode($photo['body']);
$photos[$photo->id] = $photo->source;
}
As you can see, im getting a list of the albums, then using a batch request to get all the cover photos for those albums.
Using my clients page ID, this doesn't work, nothing is returned. However if I use another page's ID this works.
So I put this down to authorisation. I noticed that if I used the Graph API explorer with an access token I could get the photos. Because of this, I copied the Token I had generated with the API explorer, and set it globally on the site using the following function and this works.
$Facebook->setAccessToken($token)
Obivously this isn't a very robust solution as the tokens only exist for a finite amount of time. I tried getting a token for the app using the /oauth/access_token API call with my apps details and successfully got a token back. If I use this as the token I can no longer see the data I was getting with the temporary token from the graph explorer however.
I do not want users to have to login just in order to see the photo gallery on the site.
How do I go about getting a token for the app that would allow me to do this?
Thanks.

im building a facebook app and i want to notify the user
https://developers.facebook.com/docs/games/notifications
im using facebook php sdk
what i do:
user auths the app and accepts permission
i get the accesstoken like:
$facebook->getAccessToken()
and then i generate a long-time token like:
public function generateLongTimeToken($token){
$long_time_token_req_body = array(
"grant_type"=>"fb_exchange_token",
"client_id"=>$this->facebookOptions["appId"],
"client_secret"=>$this->facebookOptions["secret"],
"fb_exchange_token"=>$token
);
$query = http_build_query($long_time_token_req_body);
$lttreq = file_get_contents("https://graph.facebook.com/oauth/access_token?".$query);
$lttresp = parse_str($lttreq, $output);
if ( array_key_exists("access_token", $output)){
$this->logger->info("Facebook-app: Successfuly generated long_time_token");
return $output["access_token"];
}else {
$this->logger->err("Facebook-app: generating oauth long_time_token failed \n".$lttreq);
return false;
}
}
some later i use this token for background processes to post on the users wall and them all work fine
now i also want to notificate the user like that :
public function notifyUser($message,$facebookClientId,$token){
$appsecret_proof= hash_hmac('sha256', $token, $this->facebookOptions["secret"]);
$req_body = array(
"access_token"=>$token,
"appsecret_proof"=>$appsecret_proof,
"href"=>"/index",
"template"=>$message,
"ref"=>"post"
);
$query = http_build_query($req_body);
$url = "https://graph.facebook.com/".$facebookClientId."/notifications?".$query;
$lttreq = file_get_contents($url);
return $lttreq;
}
but when i try to notify the user i always get empty data back
when i open the url in browser with all parameters facebook returns the same
{
data: [ ]
}
so i have no idea whats going on,when i look on SO i only find about people posting to sites but i want to notify the user itself
thanks for any help
First, from the Facebook docs:
Currently, only apps on Facebook.com can use App Notifications.
Notifications are only surfaced on the desktop version of
Facebook.com.
Also, an App Token is needed, not a User Token.
Btw, file_get_contents is very bad, use CURL for Facebook. May be another reason why it does not work. A basic example of using CURL with the Facebook API: http://www.devils-heaven.com/extended-page-access-tokens-curl/
Additional Info: I recently wrote a blogpost about App Notifications, it is in german but the small code part may be interesting for you: http://blog.limesoda.com/2014/08/app-notifications-facebook-apps/
Im getting started with the php sdk, and struggling to understand a few things (I have a basic example below - but everytime the pic goes to MY wall and not the fan page)
Code:
require_once("facebook.php"); // set the right path
$config = array();
$config['appId'] = 'app id';
$config['secret'] = 'app secret';
$config['fileUpload'] = true; // optional
$fb = new Facebook($config);
$params = array(
// this is the access token for Fan Page
"access_token" => "I create this via the graph api (select App and click get token), I select publish stream and photo_upload permissions.",
"message" => "test message",
"source" => "#" ."photo.png", // "#" .
);
try {
// **** is Facebook id of Fan page
$ret = $fb->api('/****/photos', 'POST', $params);
echo 'Photo successfully uploaded to Facebook Album';
} catch(Exception $e) {
echo $e->getMessage();
}
the picture keeps going to MY wall (logged in user) and not the fan page, is that because im getting a token for the currently logged in user (me) instead of the fan page? and if so how do i generate a token for the fan page whilst logged in as the developer? (is it by putting the fan page id into the Get bar?)
Apologies for the noob questions but the facebook documentation sucks (until u understand the core functionality of course). Most tutorials work once u know how to use the graph API - none ive looked actually EXPLAIN how to use the graph to generate correct tokens, etc.
\POST /<ID>/photos — this will post on the <ID>'s wall only, so please double-check the <ID> that you are using.
The access token will depict that on behalf of whom the photo would be posted on the <ID>'s wall. If you use the user access token, the photo will be published on behalf of the user and if page access token is used, it will be published on the page's behalf itself.
You can get the page access token of your pages by-
\GET /me/accounts?fields=access_token
(permission required: manage_pages)

I tried to retrieve the latest 10 photos from my picasa account but it doesn't work.
$file = file_get_contents("http://picasaweb.google.com/data/feed/api/user/firdawsfm?kind=photo&max-results=10&alt=json&access=public&thumbsize=".$tSize);
print_r($file);
the result :

there is no data about photos. when I tried this exemple with another account it works. I verified the photos are public.
I tried your url and all works fine, i can access gphoti$id and media$group values.
So far seems all ok ;) Try again!
Maybe you didn`t have public photos at that time there...
Not relevant answer to that question
(in case if server requests authorisation):
For all Picasa web albums api queries with alt=json, or alt=json-in-code and /userid/default/ you must provide access_token parameter.
Access token you can get using OAuth2 authorization work-flow as described here:
http://code.google.com/p/google-api-php-client/wiki/OAuth2 (using google-api-php-client SDK for example)
And using in scopes this value "http://picasaweb.google.com/data/".
More how to do OAuth2 and get access token from https://accounts.google.com/o/oauth2/token
after requesting user login: https://accounts.google.com/o/oauth2/auth you can find on official website:
https://developers.google.com/accounts/docs/OAuth2Login
In final you must have:
$file = file_get_contents("http://picasaweb.google.com/data/feed/api/user/firdawsfm?kind=photo&max-results=10&alt=json&access=public&thumbsize=".$tSize."&access_token=".$access_token);
print_r($file);
I have a client who wants their company's Facebook newsfeed/timeline to be displayed on their website. It's not a personal timeline/newsfeed, but an organisation's.
Everything I've read seems a few years old, but the upshot appears to be: Facebook wants to keep all its data on its own servers -- they don't want people exporting it, and people have been banned for trying. (As I say, this information was several years old.)
The closest current thing I've found is the Activity Feed Plugin, but that only registers other user's interactions with the site or a FB app.
Has anyone had any success exporting their public updates to an external website, or do I have to tell my client that it can't be done?
Thanks for any help!
AFAIK, it is possible, in a way. The simplest solution, but not best for your situation could be the Like Box plugin:
The Like Box enables users to:
See how many users already like this Page, and which of their friends like it too
Read recent posts from the Page
Like the Page with one click, without needing to visit the Page
Better solution: use their Graph API, however you can only read the data(as JSON), not have the stream exactly replicated on your client's website, don't expect to be able to apply the styles that facebook uses(i.e you won't be able to scrape it), you'll have to either replicate it, or create your own styles.
Now if the page is public and can be read by all, as in there are no privacy rules, then you can simply call the url with any valid access_token(can be app access_token also):
https://graph.facebook.com/<clientpagename_OR_id>/feed
or
https://graph.facebook.com/<clientpagename_OR_id>/posts
depending on what exactly you need, try the graph api explorer to check that(and also see the kind of data being returned). When there are lots of posts, there will be pagination urls, which you'll be able to notice in the explorer too.
Incase the page is not public, you'll need an access_token with the read_stream permission, hence you'll need to create a facebook app, of type website. Then get your client's page's admin to authorize the app, with read_stream permission. After that you can call the urls with the access_token that you receive after authentication and can continue reading the stream.
https://graph.facebook.com/<clientpagename_OR_id>/posts?access_token=thetoken
In this case use the PHP SDK, to simplify authentication and calling the graph api.

Good luck.
Edit: you do need an access token to access the feed or posts connections, but you do not necessarily need an access token to read the page object itself, as given in this documentation.
Note from the doc:
For connections that require an access token, you can use any valid access token if the page is public and not restricted. Connections on restricted pages require a user access token and are only visible to users who meet the restriction criteria (e.g. age) set on the page.
You can retrieve the organization's newsfeed using Facebook's Graph API. Timeline can't be retrieved via public API.
There is no plugin to do this. You would need to call
https://graph.facebook.com/USER_ID/home
which gives you a JSON response.
You then need to parse the JSON into a new layout on the organization's web page.
Confusingly, calling
https://graph.facebook.com/USER_ID/feed
doesn't retrieve the newsfeed, but a user's wall posts, which may or may not be what you want.
Here is a tutorial that goes through the basics of setting up a newsfeed on a website with php.
The easiest way to do this is to read the Facebook timeline RSS:
function FacebookFeed($pagename, $count, $postlength) {
$pageID = file_get_contents('https://graph.facebook.com/?ids='.$pagename.'&fields=id');
$pageID = json_decode($pageID,true);
$pageID = $pageID[$pagename]['id'];
ini_set('user_agent', 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.9) Gecko/20071025 Firefox/2.0.0.9');
$rssUrl = 'http://www.facebook.com/feeds/page.php?format=rss20&id='.$pageID;
$xml = simplexml_load_file($rssUrl);
$entry = $xml->channel->item;
for ($i = 0; $i < $count; $i++) {
$description_original = $entry[$i]->description;
$description_striphtml = strip_tags($description_original);
$description = substr($description_striphtml, 0, $postlength);
$link = $entry[$i]->link;
$date_original = $entry[$i]->pubDate;
$date = date('d-m-Y, H:i', strtotime($date_original));
$FB_feed .= $description."…<br>";
$FB_feed .= "<small><a href='".$link."'>".$date."</a></small><br><br>";
}
return $FB_feed;
}
Yes, it can be done. First register the web site at facebook's developer page. Than you can use any suitable API for interacting with FB. Sometimes ago I used SpringSocial (since I was working tightly with Spring)... You can use FB's own api which is also very useful you can read the tutorial here
It can definitely be done. You just need to get an access token through facebook and then you can access a JSON feed of posts through the facebook API.
You need to go to the facebook developer site and click on Apps at the top. Follow the steps to get an app secret and client ID. Then just put them into the following URL and it will return your access token:
https://graph.facebook.com/oauth/access_token?grant_type=client_credentials&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET
Step by step instructions here: http://smashballoon.com/custom-facebook-feed/access-token/
This document details the steps to obtain the facebook access tokens and the using the tokens to fetch FB feeds.
Example:
A live example is available in
https://newtonjoshua.com
Introduction to Graph API:
The Graph API is the primary way to get data in and out of Facebook's platform. It's a low-level HTTP-based API that you can use to query data, post new stories, manage ads, upload photos and a variety of other tasks that an app might need to do.
FaceBook Apps:
https://developers.facebook.com
Create a Facebook app. You will get an App_Id and App_Secret
Graph API Explorer:
https://developers.facebook.com/tools/explorer/{{App_Id}}/?method=GET&path=me%2Ffeed&version=v2.8
You will get an access_token which is short lived. So this will be our short_lived_access_token.
note: while creating access token select all the fb fields that you require.This will give permission to the access token to fetch those fields.
Access Token Extension:
https://graph.facebook.com/oauth/access_token?grant_type=fb_exchange_token&client_id={{App_Id}}&client_secret={{App_Secret}}&fb_exchange_token={{short-lived-access_token}}
You will get an access_token with a validity of 2 months.
Access Token Debugger:
https://developers.facebook.com/tools/debug/accesstoken?q={{access_token}}&version=v2.8
you can check check the details of the access_token.
Facebook SDK for JavaScript:
Include the below JavaScript in your HTML to asynchronously load the SDK into your page
(function (d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) {
return;
}
js = d.createElement(s);
js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
Graph API:
Let's make an API call to get our FB id, profile pic, cover pic and feeds.
window.fbAsyncInit = function () {
FB.init({
appId: '{{App_Id }}',
xfbml: true,
version: 'v2.7'
});
FB.api(
'/me',
'GET', {
fields: 'id,picture{url},cover,feed',
access_token: {{access_token}}
},
function (response) {
if (response.error) {
console.error(response.error.message);
}
if (response.picture.data.url) {
profilePic = response.picture.data.url;
}
if (response.cover.source) {
coverPic = response.cover.source;
}
if (response.feed.data) {
feeds = response.feed.data;
feeds.forEach(function (feed) {
// view each feed content
});
}
if (response.feed.paging.next) {
nextFeedPage = response.feed.paging.next;
// a request to nextFeedPage will give the next set of feeds
}
}
);
};
Use the Graph API Explorer to design your query that should be entered in the 'fields' (eg: 'id,picture{url},cover,feed')
Now you can fetch your Facebook data from Facebook Graph API using your access_token.
Refer to https://developers.facebook.com/docs/graph-api/overview/
Note: Your access_token will expire in 2 months. Create a new access_token after that.
I have written an Application what posts Photos on a FanPage into a Specific Album long time ago.
Now I didn't used for a half year. Now I had to set up the Application again and grant the extended Permissions to the Fan Page (streamm_publish) again.
But now I've a Problem, I'm using the old REST API what now gives me the error: An unknown error ocurred with the error code 1.
Then I tried to post throught the Facebook Graph api.
I tried to make a call to the Api /pageid/albumid/photos what's not working(Unknown path components)
I tried to makea a call to /albumid_from_my_page/photos then the Photos were posted to my profile
I tried to upload it to /pageid/photos what is the same as the one above
But the code fpr the REST Api worked well, what's the problem there, and why the new Graph Api isn't working how she should?(BUG?)
To post a photo to an album, this is the code:
$post_data = array(
"message" => "My photo caption",
"source" => '#' . realpath($file)
);
$album_id = "XXXXX";
$facebook->api("/$album_id/photos", 'post', $post_data);
Now I suppose to interact with the page albums you need a page access_token added to your $post_data array, for this check this answer.
You need take ACCESS_TOKEN page...
try:
http://graph.facebook.com/me/accounts?access_token= GET THIS TOKEN USING GRAPH API... OR MAKE USING the getAccessToken()...
and will see all pages and aplications that u have, find just application for this case and COPY TOKEN... and damn!!!
It's possible to see this token thought GRAPH API EXPLORER...
regards.
