Invite friends to an application - Facebook

Question

Previously my this code worked well but now it do nothing
I want to show an dialog then the user will be able to select some friends and invite them to use this application.
Now this code shows blank page.

<?php
include_once "fbmain.php";
if (isset($_REQUEST['ids'])){
echo "Invitation Sent";
    $string = "<script type='text/javascript'>top.location.href='{$fbconfig['appBaseUrl']}';</script>";
    echo $string;
}
else {
?>
 <fb:serverFbml style="width: 500px;">
 <script type="text/fbml">
  <fb:fbml>
      <fb:request-form
                action="<?=$fbconfig['baseUrl']?>/invite.php"
                target="_top"
                method="POST"
                invite="true"
                type= <?php echo $fbconfig['appname']; ?>
                content="I tried this and love this, what about you ? <fb:req-choice url='<?php echo $fbconfig['appBaseUrl']; ?>' label='Accept' />"
                >

                <fb:multi-friend-selector
                showborder="false"
                actiontext=<?php echo $fbconfig['appname' ]; ?>>
    </fb:request-form>
  </fb:fbml>
</script>

Now to invite friends the only way is to use FB JS the code

function showInvite()
{
<?php
if (strlen($fbconfig['appname' ])>50)
{
 $title = substr($fbconfig['appname' ],0,45);
 $title = $title . ' ...';
}
else
 $title = $fbconfig['appname' ];

if (strlen($fbconfig['appBaseUrl'])>200)
{
 $message = substr($fbconfig['appBaseUrl'],0,200);
 $message = 'I just love this App, now it\'s your turn to try it @ '.$message;
}
else
 $message ='I just love this App, now it"s your turn to try it @ '.$fbconfig['appBaseUrl'];
?>
 var r = FB.ui({ 
            method : 'apprequests',
            message: '<?php echo $message; ?>',
            title: '<?php echo $title; ?>',
           });
}

Solution 2

Facebook has deprecated this legacy FBML plugin. While it may still work for a while, you will want to upgrade to their new Requests Dialog, which will be easier to get support for. Also, I've noticed some other deprecated features stop working lately (yet they haven't officially been killed), so this may be the case. But check the javascript console for any errors and post them.

Try out code on this page, it would certainly help https://developers.facebook.com/docs/reference/dialogs/requests/

Seems like this is what you are looking for

<script>
   FB.init({
    appId  : 'APPID',
    });

   FB.ui({method: 'apprequests', message: 'My Great Request'});                       
</script>
