Facebook PHP SDK

https://github.com/facebook/php-sdk


Facebook PHP SDK
<?php
require '../lib/facebook/facebook.php';

$facebook = new Facebook(array(
'appId' => 'YOUR_APP_ID',
'secret' => 'YOUR_APP_SECRET',
));

// Get User ID
$user = $facebook->getUser();


Facebook PHP SDK

Kein PSR-0? WTF?


Facebook PHP SDK – PSR-0 work-a-round
<?php
require_once(__DIR__.'/facebook.php');

/**
* Facebook client, PSR-0 style
*/

class Facebook_Client extends Facebook
{
}


Facebook PHP SDK – PSR-0 work-a-round
<?php

$facebook = new Facebook_Client(array(
'appId' => 'YOUR_APP_ID',
'secret' => 'YOUR_APP_SECRET',
));

// Get User ID
$user = $facebook->getUser();

Request Flow

HTTP Post Request
+ signed_request

User / Facebook Applikations-
Browser Fanpage server


Request Flow - signed_request

 sicherer Datenaustausch zw. Facebook und der eigenen
App
 Konkatenation HMAC SHA-256 Signatur, einem Punkt (.)
und einem base64 kodierten JSON Objekt
 Zum Dekodieren wird das App Secret benötigt!
 Enthält Informationen zum User, Fanpage und Deeplink
Parameter


Wer ist der User?


Login / Authentifzierung
FB.getLoginStatus(function(response) {
if (response.authResponse) {
// User eingeloggt
} else {
// Versuchen den User einzuloggen
FB.login(function(response) {
if(response.authResponse) {
if(response.perms) {
// ist eingeloggt....
}
}
}, {
perms: 'publish_stream, offline_access'
});
}
});

The Graph API presents a simple,
consistent view of the Facebook social
graph, uniformly representing objects in
the graph and the connections between
them.


Graph API – Wer bin ich?

https://graph.facebook.com/me?
access_token=


Graph API – Wer sind meine Freunde?

https://graph.facebook.com/me/friends?
access_token=


Graph API – Was mag ich?

https://graph.facebook.com/me/likes?
access_token=


Graph API (JS Style)
FB.api('/me', function(response) {
alert(response.name);
});


Graph API (JS Style)
var msg = 'Hello phpugffm!';

FB.api('/me/feed', 'post', { message: msg }, function(response) {
if (!response || response.error) {
alert('Error occured');
} else {
alert('Post ID: ' + response.id);
}
});


Graph API (PHP Style)
<?php

$post = array(
'message' => 'Hello phpugffm!',
);

$facebook->api('/me/feed', 'post', $post);


FQL enables you to use a SQL-style
interface to query the data exposed by
the Graph API.


FQL Tabellen

album, application, apprequest, checkin, comment,
comments_info, connection, cookies, developer, domain,
domain_admin, event, event_member, family, friend,
friend_request, friendlist, friendlist_member, group,
group_member, insights, like, link, link_stat, mailbox_folder,
message, note, notification, object_url, page, page_admin,
page_blocked_user, page_fan, permissions,
permissions_info, photo, photo_tag, place, privacy,
privacy_setting, profile, question, question_option,
question_option_votes, review, standard_friend_info,
standard_user_info, status, stream, stream_filter,
stream_tag, thread, translation, unified_thread,
unified_thread_action, user, ...


FQL (JS Style)

FB.api({
method: 'fql.query',
query: 'select first_name,last_name,email from user
where uid = me()'
},
function(response) {
console.log(response);
});


FQL (JS Style) - Subselect

FB.api({
method: 'fql.query',
query: 'select first_name,last_name,email from user
where uid IN (SELECT uid2 FROM friend WHERE uid1 =
me())'
},
function(response) {
console.log(response);
});


Wallpost (JS Style)

var pageId = 12345678;
var post = {
message: '',
name: 'Der Name des Links',
caption: 'Die Beschreibung',
link: 'http://www.facebook.com/'+pageId,
attribution: 'Meine App'
};

FB.api('/'+pageId+'/feed', 'post', post);


Wallpost (PHP Style)
<?php

$pageId = 12345678;
$post = array(
'message' => '',
'name' => 'Der Name des Links',
'caption' => 'Die Beschreibung',
'link' => 'http://www.facebook.com/'.$pageId,
'attribution' => 'Meine App'
);

$facebook->api('/'.$pageId.'/feed', 'post', $post);
