I'm very new in FB Graph and I want to get the attendings list of an event with, if possible, the email of each one.
Now, after some work:
In the login script:
I set the "email" permission
$permissions = ['email']; // optional
$loginUrl = $helper->getLoginUrl('http://xxxx', $permissions);
In the callback:
I get attending list (but Name and Id only)
For each attending I call
$request = $fb->request('GET', '/'. $attending['id'].'?fields=id,name,email');
$response = $fb->getClient()->sendRequest($request);
$graphObject = $response->getGraphObject();
$email = $graphObject->getProperty('email'); // This is not getting any thing
But cannot get the email addresses.
Doing some tests I replaced the $attending['id'] withe 'me'_
$request = $fb->request('GET', '/me?fields=id,name,email');
and I got my email address.
Where I'm wrong?
Thanks for your answer.

You can only get the email of a user who authorized your App with the email permission. There is no way to get the attendees including their emails - for obvious reasons, you would not be allowed to store or use their emails in any way without their explicit permission to do so.

I am using fboauth for enabling login with facebook for the website. Here is an overview of how I achieve the functionality:
When the user clicks on the facebook login button on the website, he or she is taken to a facebook login page. After logging in with facebook, the user is taken to the app authorization page where the user asks for permission to connect with the app. Once necessary permissions are granted, a local account (account at my website) is automatically created for the user and the user is brought back to a welcome page to set password. The user won't even have to verify their email address. On subsequent visits, when the user clicks on the login link, he/she is taken to the same facebook login page where they supply their login credentials. On successful login, they are brought back to the website. So far, everything works fine with the fboauth module.
What I am trying to achieve now is a functionality similar to what is found with the fbconnect module. The user is provided with a block/page where the user can import the list of his friends who has authorized with the app, and see the links to their local accounts (accounts at the website). How to achieve this functionality? The fboauth module has its own API which can be utilized. Here is what I already have, written using the API of fboauth.
<?php
module_load_include('inc', 'fboauth', 'includes/fboauth.fboauth');
module_load_include('module', 'fboauth', 'fboauth');
module_load_include('php', 'fboauth', fboauth.api');
module_load_include('inc', 'fboauth', 'includes/fboauth.field');
module_load_include('inc', 'fboauth', 'includes/fboauth.pages');
module_load_include('inc', 'fboauth', 'includes/fboauth.profile');
/**
* Implements hook_menu().
*/
function mymodule_menu() {
$items['my-friends'] = array(
'title' => t('Your Friends'),
'page callback' => 'friend_import',
'access callback' => TRUE;
);
return $items;
}
function friend_import() {
$result = fboauth_graph_query('me/friends?fields=id', $access_token);
drupal_set_message(t('Import complete!'));
$accounts = array();
$output = "";
foreach($result->data as $fbuid){
$accounts[] = user_load(fboauth_uid_load($fbuid->id));
$output = l($account->name, "/user/" . $account->uid);
}
dpm($accounts);
return $output;
}
This will import all the friends of a user who have authenticated for the app as an object into $result (having name and user id). However, what I am finding it difficult is to display those names with the user's corresponding local accounts (accounts at the website). This is because of my lack of knowledge in php. What I am looking for is here is the exact lines of code that can be inserted after $result recieves its value so that the names of the users are displayed along with the links to their profile pages at the website.
Ok, so, if you look at the fbconnect module, you will see that there is a table that contains both the fid and uid (FB's and Drupal's). There is also a function you can user, to save you from the work of writing the query yourself:
/**
* Load a Drupal User ID given a Facebook ID.
*/
function fboauth_uid_load($fbid) {
$result = db_query("SELECT uid FROM {fboauth_users} WHERE fbid = :fbid", array(':fbid' => $fbid));
$uid = $result->fetchField();
return $uid ? (int) $uid : FALSE;
}
So, in order to get all friends, you would first need to call the the function that returns user's friends in FB:
$result = fboauth_graph_query('me/friends?fields=id', $access_token);
Then, iterate through that $result and get the local data:
$accounts = array();
foreach($result->data as $fbuid){
$accounts[] = user_load(fboauth_uid_load($fbuid->id));
}
So far, I think you had already figured this out.
Next thing we do, depends on how you want the module to behave. If you need a custom page, with an url, implement hook_menu to create that page:
/**
* Implements hook_menu().
*/
function mymodule_menu() {
$items = array();
$items['desired/path'] = array(
'title' => t('My friends'),
'page callback' => 'fb_friends', <-- This function you need to create now
....
);
function fb_friends() {
$result = fboauth_graph_query('me/friends?fields=id', $access_token);
$accounts = array();
$output = "";
foreach($result->data as $fbuid){
$accounts[] = user_load(fboauth_uid_load($fbuid->id);
$output .= l($account->name, "/user/" . $account->uid) . </br>;
}
return $output;
}
For better formatting, instead of building the $output yourself, you would call theme_table, that does it for you: https://api.drupal.org/api/drupal/includes!theme.inc/function/theme_table/7
Lastly, I recommend saving the relationships to a user and his friends in a local table, so next time you don't have to go to FB. I think you can take it from the example above. If your problem is showing the friends, it will do, although not very efficient because of going to FB everytime. Hope it helps.
You need either a user id or name or email to match Drupal's corresponding fields. These three fields are unique for a Drupal site. Unless the query to FB return any of those, you won't be able to map a FB user to a Drupal user.
Provided that the name or the user id are the same for drupal app, you can do:
$output = "";
foreach ($result as $u) {
$output .= $u->name , "<br>"; //or $u->id for the id
}
return $output;
This will work if A) $result contains a list of objects, B) Those are the exact field names.
The other issue is that if you want a custom page with the output, you need to implement the hook_menu so you can provide such custom page in your module.
I recommend you install the Devel module for easily inspection your data. After you install it and enable it, just call dsm($result) from your code, so you have a nice view of what is in the $result variable.
And before actually building that into a module, try simply adding a basic Drupal page, set the format to PHP and write that code, so you can test easily and then move that into the module.
So to recap, the first thing to do is to find out what comes in that variable and in which structure. Then, if any of those fields have the same value for the local users, just write the hook_menu and provide a custom page within your module.
Provided that you have, say, the user id (Drupal's Id) you can build a link to the user account by printing $output .= '' . $name . '<br>'; and then return $output;
If you give me the $result content here, I might come up with a better solution.
Trying to get the gender of users who like a particular (public) post. I can get a list of app-specific-user-ids of everyone who liked the post, but when I query for their profiles, I only get first and last name:
/v2.0/10203862301234567
{u'first_name': u'John',
u'id': u'10203862301234567',
u'last_name': u'Doe',
u'link': u'https://www.facebook.com/app_scoped_user_id/10203862301234567/',
u'name': u'John Doe'}
Even if I specify the fields, I still do not get gender back:
/v2.0/10203862301234567?fields=gender
{u'id': u'10203862301234567'}
Am I doing something wrong?
It's not from lack of a gender, as I can navigate (logged in to my personal account) to the public post and click through to see their full public profile, which includes age/gender/location/etc.
Many thanks
I'm also having the same problem.
I can not get the gender directly.
And also I can not get the username and URL of the profile.
This API 2.0 appears to be incomplete. Basic things were lost.
But I managed to get the gender indirectly, through the use of array. See below.
// graph api request for user data
$request = new FacebookRequest( $session, 'GET', '/me' );
$response = $request->execute();
// get response
$graphObject = $response->getGraphObject()->asArray();
echo 'sex:'.$graphObject['gender'];
Try this. Work for me.
In FB SDK 3.0, you could run $facebook->getUser() to get the user's Facebook UID.
SDK 4.0 doesn't have a BaseFacebook object any more; I can't see how to get the user ID off of a FacebookSession created by FacebookJavaScriptLoginHelper. How do you do it?
If you already have an active session or an access token, you can do the following to get the user_id:
// set session from cookie or via helper
$session = new FacebookSession( $session->getToken() );
$user_id = $session->getSessionInfo()->asArray()['user_id']
echo $user_id
See this tutorial for information on using a session saved in a cookie or creating a new session. It's a long solution but this the easiest way to retrieve the user_id using the new SDK. It's advisable to save it in a session for easier retrieval.
As of PHP SDK v4.0.3 there's no way to get the user ID without doing a network request. This is unfortunate because the signed request already contains the user_id, so it seems silly to do a network request just for that one piece of data.
But, if you're willing to do the network request, $session->getSessionInfo()->getId() will retrieve the full session info from /debug_token, including the user ID.
You might prefer to do a FacebookRequest for /me, which will provide the user ID and the user's profile info. (But it's more typing.)
$me = (new FacebookRequest(
$session, 'GET', '/me'
))->execute()->getGraphObject(GraphUser::className());
echo $me->getId();
I use Facebook SDK 4.0.9.
I needed to get the user id when making AJAX calls and my setup is as follows:
when constructing fb sdk wrapper, call FacebookSession::setDefaultApplication(<ID>, <SECRET>
defined a function get_user_id as follows:
public function get_user_id() {
$sr = new SignedRequest((new FacebookJavaScriptLoginHelper())->getRawSignedRequestFromCookie());
return $sr->getUserId();
}
getRawSignedRequestFromCookie is defined here https://github.com/facebook/facebook-php-sdk-v4/blob/master/src/Facebook/Helpers/FacebookSignedRequestFromInputHelper.php#L159-L165
I chose FacebookJavaScriptLoginHelper for convenience, but I think you can opt for any (I guess): https://github.com/facebook/facebook-php-sdk-v4/tree/master/src/Facebook/Helpers
If you already have an active session called '$session' then you just use:
$session->getUserId();
In my code I log on with Javascript SDK, then in PHP:
FacebookSession::setDefaultApplication($api_key, $api_secret);
$helper = new FacebookJavaScriptLoginHelper();
try {
$session = $helper->getSession();
$output = $session->getUserId();
} catch(FacebookRequestException $ex) {
// When Facebook returns an error
$output = '-1';
} catch(\Exception $ex) {
// When validation fails or other local issues
$output = '-2';
}
I am trying to delete an application notification on application load.
So when I invite my friend he gets a notification and requests "ok" and if he clicks on it then it should be deleted. How? I have tried multiple ways but haven't succeeded.
$REQIDs=$_REQUEST['request_ids'];
$user_profile = $facebook->api('/me');
$token_url = "https://graph.facebook.com/oauth/access_token?client_id=XXXXXXXX&client_secret=XXXXXXX&grant_type=client_credentials";
$access_token = file_get_contents($token_url);
if($REQIDs){
$requests = explode(',',$REQIDs);
foreach($requests as $request_id){
$deleted = file_get_contents("https://graph.facebook.com/$request_id?$access_token&method=delete");
//not working ->> {"error":{"type":"GraphMethodException","message":"Unsupported delete request."}}
$deleted = file_get_contents("https://graph.facebook.com/".$user_profile['id']."_".$request_id."?".$access_token);
//not working ->> false
$deleted = $facebook->api($request_id."?".$access_token, "DELETE");
//not working ->> Fatal error: Uncaught GraphMethodException: Unsupported delete request.
}
}
Anyone have some ideas or see the error?
Take a look at this topic here >>> Topic. It explains pretty fully how to handle apprequests.
Your code should look like this:
$reqId = $_GET['request_ids']; // Get the id of the current request
$requests = $facebook->api('/me/apprequests/?request_ids='.$reqId); //Get the request. Not sure if this is correct for specific request
$itemData = $requests[data][0][data]; //Get the data that was originally sent in the request
//Some code here to do whatever with the data
$delete_url = "https://graph.facebook.com/".$reqId."?access_token=".$token."&method=delete";
$result = file_get_contents($delete_url); //Delete the request so there is only one there next time.
This is supposed to do the work.
Good luck!
Facebook will pass you the request ids when your user clicks through. You can then make a call to this url to delete the request:
https://graph.facebook.com/[request_ids]?access_token=[your_app_accessToken]&method=delete
Note that if your application has sent a few requests to a single user, when they click the Notification Jewel in their FB header menu, your code will be sent all request ids in a comma separated string. You will need to code around this fact. I think I'm right in saying that the order of the ids in this string is oldest -> newest so to delete the most recent, you need to parse out the last id in the string and delete it.
I have an email address and want to find out if there is a Facebook user linked to this address. If there is, then I want to retrieve the url to this users profile page and save it somewhere.
I do not have a facebook application, but, if necessary, I would use existing account data to login to facebook and perform the task.
I thought this would be an easy task, but somehow it's not. I read through the Graph API documentation and there you find instructions on how to search public data. It says the format is:
https://graph.facebook.com/search?q=QUERY&type=OBJECT_TYPE
But trying this with an email address in the q param and user in the type param without further information results in an OAuthException saying "An access token is required to request this resource."
However, if you click the example search links Facebook generates a url with the mentioned access token related to the currently logged on user. Performing searches with this token gives the expected results. But i cannot figure out how to get this user session access token after logging in. Every time I search on how to get an access token I only find information regarding Facebook apps and retrieving permissions for basic or specific data access. This is, as I mentioned, not what I am looking for, as I don't have and don't need a facebook app.
Since Facebook gives me the needed token in the example links I thought it shouldn't be a problem to get it too. Or do they only have it because of home advantage?
Also, the Outlook Social Connector Provider for Facebook is able to retrieve Facebook data just via an email address (and the account data provided). So I thought, if Microsoft can do this stuff I should be also possible to do simliar things.
Last but not least this is the more frustrating since I, theoretically and practically, am already able to find users profile url just by searching for the email address. I don't even have to be logged on to Facebook. And it's not the official API way.
If I perform a web request to http://www.facebook.com/search.php?init=s:email&q=example#domain.com&type=users I get the expected search result. The problem is that I have to parse the HTML code and extract the url (that's okay) and that the result page is possibly subject to change and could easily break my method to extract the url (problematic).
So does anybody has an idea what's the best way to accomplish the given task?
The definitive answer to this is from Facebook themselves. In post today at https://developers.facebook.com/bugs/335452696581712 a Facebook dev says
The ability to pass in an e-mail address into the "user" search type was
removed on July 10, 2013. This search type only returns results that match
a user's name (including alternate name).
So, alas, the simple answer is you can no longer search for users by their email address. This sucks, but that's Facebook's new rules.
Simply use the graph API with this url format:
https://graph.facebook.com/search?q=zuck#fb.com&type=user&access_token=... You can easily create an application here and grab an access token for it here. I believe you get an estimated 600 requests per 600 seconds, although this isn't documented.
If you are doing this in bulk, you could use batch requests in batches of 20 email addresses. This may help with rate limits (I am not sure if you get 600 batch requests per 600 seconds or 600 individual requests).
In response to the bug filed here: http://developers.facebook.com/bugs/167188686695750 a Facebook engineer replied:
This is by design, searching for users is intended to be a user to user function only, for use in finding new friends or searching by email to find existing contacts on Facebook. The "scraping" mentioned on StackOverflow is specifically against our Terms of Service https://www.facebook.com/terms.php and in fact the only legitimate way to search for users on Facebook is when you are a user.
Maybe this is a little bit late but I found a web site which gives social media account details by know email addreess. It is https://www.fullcontact.com
You can use Person Api there and get the info.
This is a type of get : https://api.fullcontact.com/v2/person.xml?email=someone#****&apiKey=********
Also there is xml or json choice.
I've captured the communication of Outlook plugin for Facebook and here is the POST request
https://api.facebook.com/method/fql.multiquery
access_token=TOKEN&queries={"USER0":"select '0', uid, name, birthday_date, profile_url, pic, website from user where uid in (select uid from email where email in ('EMAIL_HASH'))","PENDING_OUT":"select uid_to from friend_request where uid_from = MY_ID and (uid_to IN (select uid from #USER0))"}
where
TOKEN - valid access token
EMAIL_HASH - combination of CRC32 and MD5 hash of searched email address in format crc32_md5
MY_ID - ID of facebook profile of access token owner
But when I run this query with different access token (generated for my own application) the server response is: "The table you requested does not exist" I also haven't found the table email in Facebook API documentation. Does Microsoft have some extra rights at Facebook?
Andreas,
I've also been looking for an "email-to-id" ellegant solution and couldn't find one.
However, as you said, screen scraping is not such a bad idea in this case, because emails are unique and you either get a single match or none. As long as Facebook don't change their search page drastically, the following will do the trick:
final static String USER_SEARCH_QUERY = "http://www.facebook.com/search.php?init=s:email&q=%s&type=users";
final static String USER_URL_PREFIX = "http://www.facebook.com/profile.php?id=";
public static String emailToID(String email)
{
try
{
String html = getHTML(String.format(USER_SEARCH_QUERY, email));
if (html != null)
{
int i = html.indexOf(USER_URL_PREFIX) + USER_URL_PREFIX.length();
if (i > 0)
{
StringBuilder sb = new StringBuilder();
char c;
while (Character.isDigit(c = html.charAt(i++)))
sb.append(c);
if (sb.length() > 0)
return sb.toString();
}
}
} catch (Exception e)
{
e.printStackTrace();
}
return null;
}
private static String getHTML(String htmlUrl) throws MalformedURLException, IOException
{
StringBuilder response = new StringBuilder();
URL url = new URL(htmlUrl);
HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();
httpConn.setRequestMethod("GET");
if (httpConn.getResponseCode() == HttpURLConnection.HTTP_OK)
{
BufferedReader input = new BufferedReader(new InputStreamReader(httpConn.getInputStream()), 8192);
String strLine = null;
while ((strLine = input.readLine()) != null)
response.append(strLine);
input.close();
}
return (response.length() == 0) ? null : response.toString();
}
This is appeared as pretty easy task, as Facebook don't hiding user emails or phones from me. So here is html parsing function on PHP with cURL
/*

Facebook has a strict policy on sharing only the content which a profile makes public to the end user.. Still what you want is possible if the user has actually left the email id open to public domain..
A wild try u can do is send batch requests for the maximum possible batch size to ids..."http://graph.facebook.com/ .. and parse the result to check if email exists and if it does then it matches to the one you want.. you don't need any access_token for the public information ..
in case you want email id of a FB user only possible way is that they authorize ur app and then you can use the access_token thus generated for the required task.
Maybe things changed, but I recall rapleaf had a service where you enter an email address and you could receive a facebook id.
https://www.rapleaf.com/
If something was not in there, one could "sign up" with the email, and it should have a chance to get the data after a while.
I came across this when using a search tool called Maltego a few years back.
The app uses many types of "transforms", and a few where related to facebook and twitter etc..
..or find some new sqli's on fb and fb apps, hehe. :)
WARNING: Old and outdated answer. Do not use
I think that you will have to go for your last solution, scraping the result page of the search, because you can only search by email with the API into those users that have authorized your APP (and you will need one because the token that FB provides in the examples has an expiry date and you need extended permissions to access the user's email).
The only approach that I have not tried, but I think it's limited in the same way, is FQL. Something like
SELECT * FROM user WHERE email 'your#email.com'
