I want to give my users the ability to invite their friends to install my app.
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
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
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; ...
