hook location not in plugin manager

[ageurtse]

i have found a hook location which works but now i have a new problem.

this is what i do but the template variables don't work when they called from within a plugin.
is there a way to inject these variables into the template.

the tekst "show attachments" is displayed at the left side in the members drop down menu

hook location is forumhome_start

this is my code

PHP Code:

$template_hook['memberaction_dropdown_items'] .= '
<li class="left">
<a href="{vb:link member, {vb:raw memberinfo}}&tab=AJGattach">
<img src="{vb:stylevar imgdir_siteicons}/profile.png" alt="" />
show attachments
</a>
</li>
';
