How to store data from facebook to local variable? - php

Im using the SDK 3 by facebook, and to store the facebook id i am doing this:
$facebook_id = $user;
Which works a treat! However... i cannot access individual items in the array, like i remember with the previous SDK you could do:
$first_name = $me['first_name'];
However, i have tried that, and $user['first_name'] and stuff but getting no where! I cant find any documentation of this either on their dev website or on the internet :/
Many thanks.
Ian.

Seems like $user is just the Facebook User ID that you get through the authentication flow. If you want to get user info, you need to make a separate Graph call, like so:
$res = $facebook->api('/me');
$first_name = $res['first_name'];

Querying the photos of a facebook page with age restriction

I am the administrator of a Facebook page which needs to have an age restriction of 17+ on it.
On my website, I am making some Graph API queries, like querying photo albums and linking to them on Facebook. I am using the PHP Facebook API.
I can't seem to get to grips around the page access tokens and when they expire and when not.
I tried to follow this answer here, which was highly voted, but it isn't clear what you do with the first access_token after you copy it. I am not sure if this is even valid any more.
I tried to access the page using the access token I get when I do me/accounts in Graph Explorer and it works, but after some time it expires and I get an exception that the token expired. I need something that stays working and doesn't expire and need me to go in and update it.
This is the code I have so far:
$fbconfig = array();
$fbconfig['appId'] = DEF_APP_ID;
$fbconfig['secret'] = DEF_APP_SECRET;
$fbconfig['fileUpload'] = false;
Facebook::$CURL_OPTS[CURLOPT_SSL_VERIFYPEER] = false;
$facebook = new Facebook($fbconfig);
//I am not sure if the following is the right way
$facebook->setAccessToken(DEF_ACCESS_TOKEN);
$facebook->setExtendedAccessToken();
...
try
{
$albums_resp = $facebook->api('/'.$id.'/albums','GET');
...
}
catch (FacebookApiException $ex)
{
error_log($ex);
}
What is the right way to achieve this?

php sdk - Facebook to gather fan page posts

I am trying to gather the last posts on my fan page to update on my website using the php SDK, I have the following code but it returns an empty array, is there something I am missing? It doesn't seem obvious to me how this won't work, I have tried for literally days now and still get no further following other tutorials etc..
require_once("fcbk/facebook.php");
$config = array();
$config['appId'] = '********';
$config['secret'] = '*********';
$facebook = new Facebook($config);
$pageid = "*********";
$pagefeed = $facebook->api("/" . $pageid . "/feed");
var_dump($pagefeed);
Thanks for all your help.
I've had the same issue, people seem to have solved it here :
Solutions is basically use FQL to filter last entries, get each post_id and retrieve each post usind another call passing all these IDs
check this post here :
Facebook FQL. Which is the easiest way to get all page changes in one single query ordered by date/time?
it worked for me.

Twitter - Already have OAuth database, how do I know who the user is?

I've already got a database set up with a table that is successfully populated with the final (permanent?) OAuth User Token and OAuth User Secret. The thing I don't understand is how I'm supposed to know what the current user's ID is, especially when it's been 2 weeks since their last login. My app is authorized by all of its users, so theoretically Twitter can look at the list of authorized apps for the current user and share the Twitter User ID, right? Isn't there some good way of requesting (on behalf of the current user) what his ID is? I feel like the temporary tokens should be able to facilitate this somehow... If it helps, every user in my app is just a Twitter account with some extra info. I'm just looking for the best way to utilize the tokens and secrets that are in my database...
I'm using PHP (libraries: Codebird-PHP & tmhOAuth) so if you could show an example in PHP that'd be nice, but really I just want to know how I'm supposed to use this information that I'm storing.
Thanks!
I'm assuming you store the data together with some username or user id that identifies the users of your website and links them to their proper twitter id. In order to get the basic info of your user, after authorization, you have to use the endpoint https://api.twitter.com/1.1/account/verify_credentials.json with a GET.
The documentation for the 1.1 API can be found here.
This returns an array. You find the username uder "screen_name" and the user id under "id" or "id_string".
The question is a possible duplicate of Get current user's info from Twitter API, but I've added an answer because that discussion points to the deprecated API. The code you find there, nevertheless, is still useful (it appears to use Abraham William's library, but the steps are basically the same). Replace the classes and functions with those you have in Matt Harris' library. I don't know codebird, sorry!
EDIT: I am also providing a code sample (tested and working, although I have issues with tmhOAuth, so I use it occasionally only for myself. I have noticed that, when I try to post, it sometimes returns some weird error codes and I can't figure out why):
// Authentication page, with button. You have already connected to your database
$mywebsiteuser = $_SESSION['website_user_id'];
$query= "SELECT * FROM `table_where_you_store_twitter` WHERE website_user_id ='$mywebsiteuser'";
$sql= $mysqli->query($query) or die($mysqli->error.__LINE__); // or whatever else to check is the query fails.
if ($sql->num_rows != 0){
//etc. retrieve data and set the sessions.
// already got some credentials stored?
if ( isset($_SESSION['access_token']) ) {
$tmhOAuth->config['user_token'] = $_SESSION['access_token']['oauth_token'];
$tmhOAuth->config['user_secret'] = $_SESSION['access_token']['oauth_token_secret'];
$code = $tmhOAuth->request('GET', $tmhOAuth->url('1/account/verify_credentials'));
if ($code == 200) {
$resp = json_decode($tmhOAuth->response['response']);
echo $resp->screen_name;
echo $resp->id;
//Etc. Instead of printing them you it's a good idea to store them in the db.
} else {
outputError($tmhOAuth);
}
// we're being called back by Twitter
} elseif (isset($_REQUEST['oauth_verifier'])) {
$tmhOAuth->config['user_token'] = $_SESSION['oauth']['oauth_token'];
$tmhOAuth->config['user_secret'] = $_SESSION['oauth']['oauth_token_secret'];
$code = $tmhOAuth->request('POST', $tmhOAuth->url('oauth/access_token', ''), array(
'oauth_verifier' => $_REQUEST['oauth_verifier']
));
if ($code == 200) {
//etc.
Anyhow, all in all, in order to get the info of a user you need them to authorize your app first. I check if I have something from my user with the user's session variables on my website, not through twitter. If I have nothing stored, I ask them to authorize the app. I hope this helps.

Facebook openID authentication for a company?

I have been implementing a Google/Facebook authentication system on my site. I use their respective service to authenticate the user, then use the results to instantiate sessions on my end. The Google one is running no problem, but for the Facebook one I have hit a snag.
I can authenticate users with no problem, but when trying to authenticate a company or other Facebook page type, it fails.
For instance, using the GraphAPI, I am able to retrieve the values shown in one of their examples https://graph.facebook.com/btaylor and store it properly.
But when I try to use the same system to authenticate a company ( https://graph.facebook.com/nike for instance), it fails since the objects are not part of the user results returned by the GraphAPI.
Normal stuff setting up the call:
$FBcookie = get_facebook_cookie(YOUR_APP_ID, YOUR_APP_SECRET);
$user = json_decode(file_get_contents_curl('https://graph.facebook.com/me?access_token='.$FBcookie['access_token']));
And when storing results, it works fine as a user:
$_Fname =$user->first_name;
$_Lname =$user->last_name;
But trying to access the expected attributes seen at the Nike example above, nothing gets returned.
I even tried echoing out the object to see whats there:
print('<pre>');
print_r($user);
print('</pre>');
For the user, I see everything, for non-user (company, event or other page type), I see nothing.
Question is, has anyone seen what other objects we may need to query via the GraphAPI? The Facebook developer pages are all over the place and have no real concise tutorials on this.
Any help would be much appreciated ;)
Company/Page info on facebook is as follows:
$user->id;
$user->name;
$user->picture;
$user->link;
$user->likes;
$user->category;
$user->website;
$user->username;
$user->description;
$user->public_transit;
So $user->first_name; and $user->last_name; don't exist.
You could try something like this :
if(empty($user->first_name)&&empty($user->last_name)){
//probably company set $user->username;
}

Facebook Graph API Search without logged in user

I'm trying to issue a Facebook Graphp API search call for groups with a specific search term. The important fact is to search for groups not only beginning with the term but also to search for the term within the group name. So something like that.
FQL => SELECT * FROM groups WHERE groupname LIKE '%term%'
As far as i know this isn't possible in FQL. Therefore I have to use the Graph API search.
http://developers.facebook.com/docs/api#search
But I have to issue th call even if the user isn't logged in. Is this possible
or is there a possibility to log in a default user with some curl calls without user interaction (without displaying a form)?
If there is a simplier solution (for instance with FQL) please tell me.
I work with the graph API and not with the FQL so I'm not 100% sure on the differences etc etc... however a way I'd try is using the cURL script at http://developers.facebook.com/docs/authentication/#authenticating-users-in-a-web-application to get an auth token, then you must add the received auth token to the graph parameters as you can see on the site (a good way to test in the graph api is to click on the example likes or queries given while logged into facebook then copying the api code and breaking up the process like that [testing that you can get results you want from the query, testing that you can get your auth token then combining] so that you know what parts are 'problem' parts).
If that fails, scroll down to the "single sign-on with java-script" and have a look at the code they use to get the auth token from the facebook cookie, I notced you may be able to access that cookie from FQL.
I hope this was of some help! Please tell me if those ideas didn't work.

Using PHP-SDK 3.1.1, no auth or access_token needed. This sample assumes you have PHP-SDK installed on the page.
Use a form post the question to the page, arguments for get and post
are included. This will return the array from search https://graph.facebook.com/search?q=facebook&type=group
<?php
$q = urlencode($_GET['qs']);
if(!$_GET['qs']){
$q = urlencode($_POST['qs']);
if(!$_POST['qs']){
$q = "facebook";
}
}
$MEsearch = $facebook->api('/search?q='.$q.'&type=group');
foreach ($MEsearch as $key=>$value) {
$i=1;
foreach ($value as $fkey=>$fvalue) {
$i++;
if($fvalue[id]=="h"){
}else{
$groupname = $fvalue[name];
$groupid = $fvalue[id];
$groupversion = $fvalue[version];
echo $groupname. '<br />';
echo $groupid. '<br />';
echo $groupversion. '<br /><hr />';
}
};
};
?>
