IsFriend Conditional

[GameWizard]

With the friends feature now becoming part of 3.7, I have tried to integrate some new features into my board. One of these is showing content in the postbit only to friends.

In my postbit_legacy template, i have the following code:

<if condition="$prepared['isfriend'] OR $post['userid'] == $bbuserinfo['userid']">
content
</if>

Now mind you, the $prepared['isfriend'] is the only conditional I'm aware of, and it seems to only function on the Memberinfo templates. I have also tried $prepared[isfriend] and $post['isfriend'] and a few other random ones. I am certain that this is either a VB limitation or something that I'm doing wrong.

In case anyone is wondering, i added $post['userid'] == $bbuserinfo['userid'] which shows the content the original user aswell, rather than just to his/her friends.

EDIT: After doing some digging, I found this in the includes/class_userprofile.php file. Line 84

    /**
    * Array of variables to 'automatically' prepare for each profile view
    *
    * @var array
    */
    var $auto_prepare = array(
        'userid',
        'username',
        'musername',
        'myprofile',
        'usertitle',
        'userperms',
        'imicons',
        'profilepic',
        'rank',
        'reputation',
        'onlinestatus',
        'lastactivity',
        'wolocation',
        'usernoteinfo',
        'isfriend',
        'canbefriend',
        'show',
    );

Clearly this is the code in question I need to use, but where would I need to move it? Or how would I need to adapt it? I tried copying it into the includes/class_postbit.php file, but no luck in showing anything.

Any help on the matter would be appreciated, as I know a few others have requested a similar feature before.
