vb3 new php file

[Logikos]

So on my older version board i had a few extra php files added on such as rules.php and inside rules.php i had this:

PHP Code:

<?php
$templatesused.='mytemplate';
require('./global.php');
eval("dooutput(\"".gettemplate("site_rules")."\");");
exit;
?>

But when i try to use that for vb 3.0.0 i get this error

Fatal error: Call to undefined function: gettemplate() in /home/hazelboy/public_html/forums/rules.php on line 4

So how do i get that template to show up?
