Hook for header template parsing?

[sinucello]

Hi,

I`d like to display the tag cloud on every page and so I tried to modify Atakan KOC tag cloud on forum home mod.

I succeeded in displaying the cloud on the home page and the forum display with the hooks:

1. forumdisplay_start
2. forumhome_start

and used the following function:

$vbulletin->templatecache['FORUMDISPLAY'] = str_replace('<!-- ###TAGCLOUD### -->', $vbulletin->templatecache['tag_cloud_forum_home'], $vbulletin->templatecache['FORUMDISPLAY']);

To be more flexible, I would rather like to replace a marker in the header template. But

$vbulletin->templatecache['header'] = str_replace('<!-- ###TAGCLOUD### -->', $vbulletin->templatecache['tag_cloud_forum_home'], $vbulletin->templatecache['header']);

won`t work with the hooks mentioned above. So I guess I have to use another hook to modify the header template.

Can anybody help me?

Thank you - all the best,
Sacha
