Include PHP in an advert

[eviljoker7075]

Thanks for the suggestion, I've given it a go but it doesn't seem to work. Would you be able to sanity check what I've done?

1. I setup a new plugin with the following details:
Product: vBulletin
Location: parse_templates
Name: included_html
Code:

ob_start();
include "/path/to/file.php";
$included_file = ob_get_contents();
ob_end_clean();

vB_Template::preRegister('navbar', array('included_file' => $included_file));

2. Created an add
Location: Below Navbar
Ad HTML:

{vb:raw included_html}

What am I missing?

--------------- Added [DATE]1365242536[/DATE] at [TIME]1365242536[/TIME] ---------------

Ok, I can see my ad code should probably be:

{vb:raw included_file}

But even when I make that change nothing is showing up...
