Everyone's been either copying and pasting or writing from scratch some code to add "Invite friends" to their Facebook apps, but now there's a simple tag that they've provided. It's currently in beta and, knowing Facebook, is bound to change and break everything a few times, but it's very easy to use:

<fb:request-form action="invite.php"
method="post" type="trust" content="Invite
friends to trust you<fb:req-choice
url='http://apps.facebook.com/i_trust'
label='Add iTrust' />"
image="http://apps.exponetic.com/itrust/
_img/iTrust-logo-magenta-small.gif">
  <fb:multi-friend-selector
actiontext="Select friends" />
 </fb:request-form>

(Note the slightly dodgy <fb:req-choice> tag inside the content attribute.)

We're now using it at Exponetic on our second Facebook application, called iTrust.

Hello



Just to tell you that this is the first Facebook Invite code I've seen that's actually working!



Thank you

It's not working for me. Do you need some other code to process the form? This is supposed to be able to invite friends to you app, right?
