FudLogin Mod


This is a try for an advanced "Single Login System" for Wikka Wiki in combination with an FUDForum based forum installation. It will allow anyone to log in with his forum login and password. On the first login, a user has to choose his WikiName, he likes to use.

I had the following goals in mind, when developing this mod:

To install this mod, you at first have to specify the path to your forum in your wikka.config.php in the following way:
  1. "fudlogin_forumpath" => "../FUDForum"  // Replace with relative path to your "non HTTP reachable" forum files (backend).


Then replace the file actions/usersettings.php with the version at the end of this page.

After doing so, any user is immediately able to login with his forum login data. Users, which already had a WikiName, will be able to enter the old WikiName on the first login. This will migrate the old WikiName to the new login system.
Users, which didn't already have a WikiName, will just choose a new one, which hasn't been already taken by someone else and isn't already in use as name for a page on your wiki.



This is the replacement for actions/usersettings.php:
