If you want to be able to show/hide things in your templates based on Usergroups, you can either use something like:


<if condition="$bbuserinfo['usergroupid'] == '9' || $bbuserinfo['usergroupid'] == '10' || $bbuserinfo['usergroupid'] == '11'">


or


<if condition="in_array($bbuserinfo[usergroupid], array(9,10,11))">


...but if those usergroup ids ever change, or you want to add more groups to the array, it could get time consuming, especially if you have multiple styles.

Wouldn't it be easier to be able to use:


<if condition="is_paid_member()">

?

Well now you can!

In includes/functions.php, find:

// ###################### Start build datastore #######################
function build_datastore($title = '', $data = '')
{
global $DB_site;

if ($title != '')
{
$DB_site->query("
REPLACE INTO " . TABLE_PREFIX . "datastore
(title, data)
VALUES
('" . addslashes(trim($title)) . "', '" . addslashes(trim($data)) . "')
");
}
}


After, add

function is_paid_member($usergroupid = 0) // replace is_paid_member with your new function/condition
{
global $bbuserinfo;

if ($usergroupid == 0)
{
$usergroupid = $bbuserinfo['usergroupid'];
}
return in_array($usergroupid, array(9, 10, 11)); // replace with the Usergroup ids you want
}


In adminfunctions_template.php find:


// vBulletin-defined functions
'can_moderate', // obvious one
'can_moderate_calendar', // another obvious one
'exec_switch_bg', // harmless function that we use sometimes
'is_browser', // function to detect browser and versions
'is_member_of', // function to check if $user is member of $usergroupid

under, add:


'is_paid_member', // function to check if $user is member of paid member groups


Save and upload includes/functions.php and adminfunctions_template.php and you are done.

You can now wrap
<if condition="is_paid_member()"></if>
around whatever you want to show to people in Usergroups 9, 10 or 11...and if you need to add usergroup 12 to the list, all you need to do is add it in the function.

Hoorah!
