History

  • 2013-02-11 partially-working version, so I have a record of the commented-out code I'm about to hack off

Code

<php> <?php /* 

 PURPOSE: SMW listing management functions for w3tpl
 REQUIRES: filed-links.php
 TODO: w3f_SiteGroupListing() is currently hard-wired for Google+
 HISTORY:
   2011-10-16 w3tpl code started to get too ugly, so pushing out some functionality into callable modules.
   2012-01-24 split off SMW stuff from filed-links.php to smw-links.php
   2013-02-14 w3f_SiteGroupListing() now works for G+
