While attempting to add another developer to my Facebook Application Settings panel after I tried to save his name, I got the following error:

“Validation failed.

Only verified developers can be added as listed developers of this application.”

A Google search brings this blog post which says here http://developers.facebook.com/blog/post/386 that

“Starting this week, we are requiring every developer to verify his or her Facebook account to create new applications. This is the same quick process that users go through when they want to do things like upload large videos.”

“You can verify your account by either confirming your mobile phone or adding a credit card to your account. Facebook will not charge your credit card if you add it to your account.”

Verifying mobile number did not resolve it and I suggested him to first add the application where I was adding him as developer and that worked for me. After he joined that Facebook app as a user, I could add him in the developers list.

Cheers!

Starting June 30, 2010, your Facebook application will only be able to read the publically available information of a user’s profile by default, the way data read permissions are granted in the platform. While the changes are broad in scope, none of them impact backwards compatibility: all of your existing code will continue to work.

The most important changes are:

• Graph API
• Data Permissions
• OAuth 2.0
• New SDKs
• Facebook Connect Branding

To get access to user’s profile information, your facebook application must explicitly request all of the data it needs to function. For instance, if you want to incorporate a user’s events into your application, you would request the user_events extended permission.During the authentication process, the user is presented with a UI in which the user can authorize your application to access that specific part of her profile.

Following is the complete list of extended permissions for Graph API:

publish_stream, create_event, rsvp_event, sms, offline_access, manage_pages, email, read_insights, read_stream, read_mailbox, ads_management, xmpp_login, user_about_me, user_activities, user_birthday, user_education_history, user_events, user_groups, user_hometown, user_interests, user_likes, user_location, user_notes, user_online_presence, user_photo_video_tags, user_photos, user_relationships, user_religion_politics, user_status, user_videos, user_website, user_work_history, read_friendlists, read_requests.

To upgrade your require_login() authentication to Graph API authorization, please check my earlier post for how to authenticate using Facebook Graph API and simply add any extended permission that you may need in your app. Go the function “RequestforPermission” in that post and add your permissions in the

  'req_perms'=>'email,publish_stream'

Cheers.

Facebook has recently introduced Graph API and simplified many things. The new Graph API attempts to drastically simplify the way developers read and write data to Facebook.The Graph API uses OAuth 2.0 for authorization. OAuth 2.0 is a simpler version of OAuth that developers used earlier for authorization as $facebook->require_login(). (by the way, old token still works)

In the previous version, RequireLogin was a one line simple way of getting authorization for user. When I upgraded to OAuth 2.0, I had a hard time getting my user authenticated which looked like very simple thing in pre Graph API days.

Here is how I finally manage to put together for my latest facebook app.

To authenticate user in Graph API, first of all, download the Facebook PHP SDK facebook.php and put it inside includes folder. After that, get the Application Id, API key, application secret and canvas url of your facebook app and put it inside following $fbconfig array.

$fbconfig['appid']  = "Application id here";
  $fbconfig['api']  = "API Key here";
  $fbconfig['secret']  = "App Secret here";
  $fbconfig['canvas_url']  = "http://apps.facebook.com/your_app_name/";
 
 
  try{
  include_once 'includes/facebook.php';
  }
  catch(Exception $o){
 print_r($o);				
	}
 
// Create our Application instance.
$facebook = new Facebook(array(
 'appId'  => $fbconfig['appid'],
 'secret' => $fbconfig['secret'],
 'cookie' => true,
 'domain' => "Your Canvas Callback URL domain here"
  ));
 $session = $facebook->getSession();
 if (!$session) {
echo RequestforPermission();
	}
else {	//got session
	try {
	$me = $facebook->api('/me');
 
	if(!IsApplicationUser($me['id'])) {
	//InsertApplicationUser($me);
            //create a function and insert the user info
             //into App DB for later use
	}
          }
 catch (FacebookApiException $e) {
RequestforPermission($fbconfig['canvas_url'] );
	}
    }

Please add this function “RequestforPermission” as well in this file.

function RequestforPermission($next_url) { 
	global $facebook;
	$loginUrl=$facebook->getLoginUrl(array(
	'canvas'=>1,
	'fbconnect'=>0,
	'display'=>'page',
	'next'=>$next_url,
	'cancel_url'=>'http://www.facebook.com/',
	'req_perms'=>'email,publish_stream',
	));
	return '<fb:redirect url="'.$loginUrl.'" />';
	  } // end redirect function

Put all this code into a file named “fb-authentication.php” and simply include “fb-authentication.php” in those files in your application where you want Facebook user authentication.

Hope that helps.

Cheers.

In a FBML Facebook App, your quick jump menu will require a little tweak to work in FBJS properly.
Just change your standard js jump menu from:

<select onchange="goto(this.options[this.selectedIndex].value)">
    <option value="page.php?id=1">Page1</option>
    <option value="page.php?id=2">Page2</option>
    <option value="page.php?id=3">Page3</option>
</select>

To this:

<select onchange="document.setLocation(this.getValue());">
   <option value="page.php?id=1">Page1</option>
   <option value="page.php?id=2">Page2</option>
   <option value="page.php?id=3">Page3</option>
</select>

Cheers.
