I am using the following code to grab info for the Facebook user.
Is there a way to get the user Pages (if the user has one or more Facebook Pages) and the IDs of these pages?
$user = $_POST['uid']; //the returned user ID from Facebook
$key = $_POST['usid']; //the returned session ID from Facebook
$accesstoken = $_POST['accesstoken']; //the returned accesstoken from Facebook
$image = "http://graph.facebook.com/" .$user ."/picture?type=large"; //Facebook Profile Picture
$name = json_decode(file_get_contents('https://graph.facebook.com/' . $user))->name; //Name of the user account on Facebook
$link = json_decode(file_get_contents('https://graph.facebook.com/' . $user))->link; //Link of the user profile on Facebook
$gender = json_decode(file_get_contents('https://graph.facebook.com/' . $user))->gender; //Gender of the user on Facebook
$locale = json_decode(file_get_contents('https://graph.facebook.com/' . $user))->locale; //Location of the user on Facebook
$url = "https://graph.facebook.com/". $user ."/feed?limit=1&access_token=".$accesstoken; //We get the latest status update on the Facebook Wall
$json = file_get_contents($url);
$jsonData = json_decode($json);
foreach($jsonData->data as $val) {
if($val->from->id == $user) {
$statusmessage = $val->message; //Finally we got the latest status update if there is one on The Facebook Wall
break;
}
}
If you asking how to get additional user profiles, of a single user, based on their Facebook Id: the answer is you can't. Facebook mandates one profile per user. And while in real life a user can have multiple profiles, there is no reliable means of extracting that data from the graph.
However, if you're asking how to get the ids of pages the user admins then use:
https://graph.facebook.com/USER_ID/accounts
this will require a valid access token for the given user.

I am not able to get the Facebook friends list using the API. It was working fine earlier but not anymore. Here is the code I have used. Can someone help to validate the code. Thanks in advance.
<?php
require_once('PHPMailerAutoload.php');
require_once('PHPMailerConfig.php');
require_once("facebook/facebook.php");
$config = array();
$config['appId'] = '***************';
$config['secret'] = '*******************************';
$facebook = new Facebook($config);
$uid = $facebook->getUser();
if(!empty($_GET['error'])) {
echo "User cancelled the authentication with facebook";
echo "<script>
window.opener.location.href='merror.php';
window.close();
</script>";
exit;
}
if($uid) {
$url = $uid.'?fields=id,work,friends,email,picture.width(450).height(450)';
$user_profile = $facebook->api($url);
$friends = $facebook->api('/me/friends');
$d = '';
foreach($friends['data']as $val) {
$d .= $val['id'].',';
}
}
?>
Please read the docs before posting a question which has been answered here hundreds of times.
See
https://developers.facebook.com/docs/graph-api/reference/v2.3/user/friends#read
A user access token with user_friends permission is required to view the current person's friends.
This will only return any friends who have used (via Facebook Login) the app making the request.
If a friend of the person declines the user_friends permission, that friend will not show up in the friend list for this person.
I'm trying to get a "list" of random likers who follow a Facebook Page. I'm using this code to get some fans (not random fans, but this is something else).
<?php
function fetch_fb_fans($fanpage_name, $no_of_retries = 10, $pause = 500000){
$ret = array();
/* get page info from graph */
$fanpage_data = json_decode(file_get_contents('http://graph.facebook.com/' . $fanpage_name), true);
if(empty($fanpage_data['id'])){
/* invalid fanpage name */
return $ret;
}
$matches = array();
$url = 'http://www.facebook.com/plugins/fan.php?connections=100&id=' . $fanpage_data['id'];
$context = stream_context_create(array('http' => array('header' => 'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:22.0) Gecko/20100101 Firefox/22.0')));
for($a = 0; $a < $no_of_retries; $a++){
$like_html = file_get_contents($url, false, $context);
preg_match_all('{href="https?://www\.facebook\.com/([a-zA-Z0-9._-]+)" data-jsid="anchor" target="_blank"}', $like_html, $matches);
if(empty($matches[1])){
/* failed to fetch any fans - convert returning array, cause it might be not empty */
return array_keys($ret);
}else{
// merge profiles as array keys so they will stay unique
$ret = array_merge($ret, array_flip($matches[1]));
}
// don't get banned as flooder
usleep($pause);
}
return array_keys($ret);
}
/*
print_r(fetch_fb_fans('cocacola', 2, 400000));
prints 73 unique fan names as array
*/
$contador = 0;
foreach (fetch_fb_fans('cocacola', 2, 400000) as $fan) {
$pageContent = file_get_contents('http://graph.facebook.com/'.$fan.'');
$parsedJson = json_decode($pageContent);
echo $parsedJson->username ."<br/>";
}
?>
Code from: Facebook API: Get fans of / people who like a page
This code give me some usernames. Now, my question, after searching Google... Is, can I get the number of pages that follow every user?
I know that Graph API let me know my likes but when I try to see other user likes it throws me an OAuthException error. I supose that I'm not doing right.
So I will apreciate some explanation about how to do this. I searched Google but I don't understand how it works.
Thanks.
The Facebook documentation is unfortunately not very clear: https://developers.facebook.com/docs/graph-api/reference/v2.2/user
However, getting the likes from a user requires:
User access token for the user
"User likes permission" granted on the access token, which is a special permission that Facebook approves on your app
Without an access token for the user you cannot see what pages they like.
While not supported, you could perhaps use a page scraper to find this information if they have it public.
Based on your question, it's not clear whether users log in to your app or if you're just trying to get information from one of your own pages, or another page. If you don't have users logging into your app, I'm afraid there's no way at all to get this information apart from a page scraper.
In a previous thread we were strugling with the Facebook login using a Laravel app. Now, as the user logs into our app using Facebook, we are trying to get his friend's list in order to provide some qualified suggestions. So, here's what we are trying:
Route::get('login/fb/callback', function() {
// A FacebookResponse is returned from an executed FacebookRequest
$helper = new FacebookRedirectLoginHelper('http://yoururl/login/fb/callback');
$session = $helper->getSessionFromRedirect();
$request = new FacebookRequest($session, 'GET', '/me/friends');
try {
$response = $request->execute();
$me = $response->getGraphObject();
} catch (FacebookRequestException $ex) {
echo $ex->getMessage();
} catch (\Exception $ex) {
echo $ex->getMessage();
}
print_r($me);//->getProperty("id"));
$user = new Giftee;
$user->name = $me->getProperty('first_name') . ' ' . $me->getProperty('last_name');
$user->email = $me->getProperty('email') . "#facebook.com.br";
$user->photo = 'https://graph.facebook.com/' . $me->getProperty('id') . '/picture?type=large';
$user->save();
});
As a result, we get:
object(Facebook\GraphObject)#146 (1) { ["backingData":protected]=> array(0) { } }
By reading the Facebook API docs, they pretty much say user_friends will only return friends of friends that already use your app and We could not see any login permission that would just return friends of friends (not only the ones using our app). In another words, is what we want really impossible?
You're not able to retrieve friends of friends. With Graph API v2.0, you even only get those friends of your app's users which also use your app.
And, all friends_* permissions have been removed. So I don't see a chance for you to implement what you want to achieve.
I have a very strange problem:
Sometimes (but not every time!) when I try to get the current user facebook ID, I get "1";
for example:
$config = array();
$config["appId"] = API_KEY;
$config["secret"] = SECRET;
$facebook= new Facebook($config);
$user=$facbook->getUser();
echo $user['id'];//returns 1;
Obviously - this it not the real user ID.
When I check if the access token is still good -I see that it is still valid. Also, even if I force the user to login again using:
FB.login(function(response) {
if (response.authResponse) {
top.location.href="<?php echo HOME_URL;?>"
}, {scope: 'publish_stream'});
Still getting the same result.
Any idea what could be the problem?
You should ONLY get an ID back from FB:
$user_id = $facbook->getUser();
echo $user_id;
You would later have to query the API for a user profile (which is what it looks like you are doing):
$user_profile = $facebook->api('/me');
Reference:
http://developers.facebook.com/docs/reference/php/facebook-api/
I have written a small piece to get the user to login :
<?php
include_once ('facebook.php');
$api_key = 'xxxxxxxxxxxxx';
$secret = 'xxxxxxxxxxxxx';
global $facebook;
$facebook = new Facebook($api_key, $secret);
$facebook->require_frame();
#Ask user to login if not logged in
$is_tab = isset($_POST['fb_sig_in_profile_tab']);
if( !$is_tab ){
$uid = $facebook->require_login($required_permissions = 'email,status_update,offline_access');
}
else{
$uid = $facebook->get_profile_user();
}
I need to retrieve the users info once I have the uid. Unfortunately I cannot find the api calls for it and there is a no IDE for facebook :(. Can anyone point me to the api's or give me here. I want to get users username, city, zipcode.
I coudnt get this to work : facebook.Schema.user user = api.users.getInfo();
I think it is for the new API lib.
Thanks.
P.S: I am not using graph APIs, because I found them to be poorly documented and I got stuck with them for a while so decided to abandon them atleast for now.
You can get it like this:
$user_info = $facebook->api_client->users_getInfo($uid, "name, city, zipcode");
print_r($user_info);
