In the code you just posted, you're never initializing $templater. So you either want to go back to the code you had (using a 'threads' template), or else use preRegister like:

PHP Code:

vB_Template::preRegister('header',array('zlink' => $zlink,
                                        'zthreadid' => $zthreadid, 
                                        'zdateline' => $zdateline)); 


then use {vb:raw zlink} etc in the header template.
