Mediawiki integration into wordpress (common navigation bar)

I want to stick the wordpress navigation bar on top of a wiki I have on the same site.

Everything else is working – I have mediawiki and wordpress using the same db for authentication and a common login/logout works, but I want it all to fit together visually. And having the menu links at the top is useful too. (For those who want the common login, the WPMW extension is still working.)

I found this thread which is pretty much exactly what I want to do, but it’s 4 years old and there are directions that don’t really line up with current version of mediawiki.

My current approach is having mediawiki call the wordpress php header and footer functions during its page build, as described in the link above. But I can’t figure out where to put this call in the mediawiki files.

Anyone have any experience with this?
