Guide to Create a Facebook App
http://developers.facebook.com/step_by_step.php
1. Add the Developer Application2. Get a web server and/with a database
service (if you will use database) – Thanks Chris!
3. Create a new App in Developer4. Configure your App:
– The form is explained very clearly at: http://developers.facebook.com/step_by_step.php
A very quick start
← define Facebook Class
← given after you create a new App

Extract data with your Apphttp://developers.facebook.com/documentation.php
Facebook APIshttp://wiki.developers.facebook.com/index.php/API#API_Metho
ds
• A lot of handy functions provided with a Facebook Object.
• For example: Users.getInfo– Returns a wide array of user-specific
information for each user identifier passed, limited by the view of the current user.
Examples of using APIs
• Get current user’s first name and last name $user_details=$this->facebook->api_client-
>users_getInfo($uid, array('last_name','first_name')); $data['first_name']=$user_details[0]['first_name']; $data['last_name']=$user_details[0]['last_name'];
Facebook Queryhttp://wiki.developers.facebook.com/index.php/FQL
• Facebook Query Language, or FQL– allows you to use a SQL-style interface to
more easily query the same Facebook social data that you can access through other Facebook API methods (assuming your application has access!).
• It can be very concise and powerful!
Examples of using FQLhttp://wiki.developers.facebook.com/index.php/Sample_FQL_Q
ueries
• Get the names of the groups of which u1 is a member: SELECT name FROM group WHERE gid IN (SELECT gid
FROM group_member WHERE uid = ''u1'')• In PHP, you write:
$query = "YOUR QUERY HERE"; //(see above examples) $array = $facebook->api_client->fql_query($query);
• The returned array is multidimensional, so $attribute = $array[0]['attribute'];
• If there are no rows returned, check to see if there are any results like this: if ($result != NULL)
FBMLhttp://wiki.developers.facebook.com/index.php/
FQBML
• Facebook Markup Language (FBML)– To me it looks like facebook CCS + a lot of
predefined dynamics elements. “You can hook into several Facebook integration points, including the profile, profile actions, Facebook canvas, News Feed and Mini-Feed.“
– Especially handy when you implement some Facebook styled things: wall posts, manipulate profile, invite friends, send out notifications…
Examples of using FBML(from the App I wrote)
• <?php• $invfbml = <<<FBML• You've been invited to take a Friendship Quiz.• <fb:name uid="$user" firstnameonly="true" shownetwork="false"/>
wants you to take the quiz: {$test_name}.• <fb:req-choice url="http://apps.facebook.com/friendshiptest/$sNextUrl"
label="Take a Friendship Quiz!" />• FBML;• ?>
• <fb:request-form type="friendship test" action="post_invitation.php5" content="<?=htmlentities($invfbml)?>" method="POST" invite="true">
• <fb:multi-friend-selector max="20" actiontext="Invite your friends to take a quiz!" showborder="true" rows="5" exclude_ids="<?=$arFriends?>">
• <input type="hidden" name="test_id" value=<?php echo $tid;?>></input>
• </fb:request-form>
