Plugin hook: postbit_display_start

Code:

ob_start();
	$usergroupid = $post['usergroupid'];
	$has_bg	= array(6);
	if (in_array($usergroupid, $has_bg)) {
		echo '<div class="userinfo" style="background:url(images/ranks/postbit/'.$usergroupid.'.png);min-height: 350px;">';
	} else {
		echo '<div class="userinfo">';
	}
$php_include = ob_get_contents();
ob_end_clean();
vB_Template::preRegister('postbit_legacy',array('postbit_background' => $php_include));

Then in postbit_legacy template, I replace the

<div class="userinfo">

with

{vb:raw postbit_background}
