Some one help fix??

[browie]

Can some one fix this for vBulletin please. It seems to work on a normal website, but not in vBulletin Style Manager.... It's a code that shows adsense only to people that come to my site through search engines.


<?
if (preg_match('/^http:\/\/(\w+\.)?(google|msn|yahoo|aol)\./',$_SERVER['HTTP_REFERER']) == 1)
{
?>
<!-- Google AdSense HTML -->
<?
}
?>

Templates cannot contain raw PHP code, use this instead:
<if condition="preg_match('/^http:\/\/(\w+\.)?(google|msn|yahoo|aol)\./',$_SERVER['HTTP_REFERER']) == 1"><!-- Google AdSense HTML --></if>

I figured "regular" php was not allowed. But there is one problem....

preg_match is not allowed.....

The following functions are allowed in template conditional expressions:
in_array() is_array() is_numeric() isset() empty() defined() array() can_moderate() can_moderate_calendar() exec_switch_bg() is_browser() is_member_of()
