User Administration Tool


I've started writing some code for a user administration tool. I think this might be interesting for wikka-based projects with a large number of registered users.
This action enables Wikka administrators (or, in the future, users belonging to an Admin group) to have access to several user management functions from a single page:


The code below (to be saved as actions/useradmin.php and used as {{useradmin}} ) is just a very first draft. Contributions and improvements are welcome (especially to make the code lighter).

Current features (2004-09-15):
  • users can be sorted by different fields (click on table header to reverse sort order), searched and paged;
  • if the current user is not an administrator, then the lastuser action is displayed
 




<?php

// USER ADMINISTRATION TOOL
// Displays to the Wikka admins a list of registered users

$page = $PHP_SELF.$this->GetPageTag();

// admin only code
