TWiki is good wiki project. I have implemented it and using. Bydefault Twiki stores data in files with extension .txt, is any plugin/method to store post data in mysql database?
How can I store data in mysql database for TWiki?
sadly, no.
I built a MongoDB backend for foswiki (a TWiki fork) http://foswiki.org/Development/MongoDBPlugin with remarkable results, and Crawford and I began work on a Database backend for it, but the work is not complete yet.
I guess the big questions are - do you need it, and do you need it enough to help make it happen :)
