Currently I just have some old hacks I made for older versions of DokuWiki. Most have been depreciated by now. Here are links to new ones.
Hiding PHP Code
I had created a way to hide imbedded PHP code in your wiki pages from users that were not allowed to edit said page. This code was rather buggy, did not work when a page’s diff was checked and when an older version was viewed.
Fortunately someone has taken my code and revised it to work much better. Please view the article on safely including php code on your pages. Thanks to Martin Brook for the update.
PrettyRecents
This was very popular and added date headers to the “Recent Changes” page on DokuWiki. Again I made this for an older version of DokuWiki, however the generous DokuWiki community helped make it better. Check out the new new PrettyRecent fix by Christopher Arndt.
