Invitations and Requests
Problem
I want to give my users the ability to invite their friends to install my app.
Solution
There are a bunch of different ways to handle the actual
invitation controls, but they all stem from the use of the fb:request-form tag. The general principle is that you start with an
fb:request-form tag and include
parameters that define what you want to do, and then you include some
combination of fb:multi-friend-selector, fb:multi-friend-input, fb:friend-selector, and fb:request-form-submit. Let’s start with a
look at the following example:
<?php
$inviteContent = htmlentities('<fb:name uid="' . $user . '" firstnameonly="true"
shownetwork="false"/> says this is the most awesomest Super Disco Napping
application ever made. Come take naps with <fb:pronoun objective="true"
uid=" ' . $user . '"/>!');
$inviteContent .= htmlentities('<fb:req-choice url="new_napper.php"
label="Take Naps with Me!" />');
?>
<fb:request-form
action="index.php"
method="post"
invite="true"
type="Disco Nap"
content="<?php echo $inviteContent?>">
<fb:multi-friend-selector actiontext="Tell all your friends! Tell the
whole bunch!" />
</fb:request-form>It’s a good idea to put the name of the user sending the invites
or requests right into the content so that it has some context for the
recipient. The fb:req-choice
tag creates a button in the actual invitation that gets
sent. You can add more than one button here, with the caveat that they
all have different URLs specified in the url parameter; ...
