Applying the code for statues

[Adem GEN?]

Hello,
Apply the code below if it is topic or message , don't apply if it is signature field, don't apply on fag page. How can I make this control for this code?

hook location - bbcode_fetch_tags

if (!($vbulletin->userinfo['userid'] > 0)) {
$tag_list['no_option']['php'] = array(
'html' => 'No viewing allowed'
);
}

Could you help please?

Thanks in advance.
