vB4 Conditional Plugin for additional.css
 

I'm attempting to create a plugin that will check certain conditions before appending css to additional.css. Here is what I have for a plugin at hook: cache_templates.

Code:
if in_array($foruminfo['forumid'] == array(2,7)) {
$sp_css = array
(
".forumbit_post .foruminfo {;",
" width: 57%;",
" min-width: 30%;",
" float: {vb:stylevar left};",
" clear: {vb:stylevar right};",
" min-height: 85px;",
"}"
)

foreach ($sp_css as $value) {
echo $value;
}

vB_Template::preRegister('additional.css',array('s p_css' => $sp_css))
If there is a way that I can have the array in this plugin display each element I think this would work. The goal in this particular experiment would be, if specfic forum ID's are matched, add these lines to additional.css. Obviously what I have here isn't working.

I'm completely new to PHP and vBulletin so be nice. :-)
