If you want to implement this with cookies or sessions you can use the http://www.pmwiki.org/wiki/Cookbook/HttpVariables recipe to implement this. If you look at these examples here: http://www.theficks.name/test/HttpVariables/pmwiki.php?n=Test.Vars you should notice that the footer at the bottom will tell you the previously visited page on that wiki. If you use the http://www.pmwiki.org/wiki/Cookbook/AllGroupHeader recipe you can set {$!PreviousPage} for every visited page like this. (:cookie PreviousPage {$FullName}:) The disadvantage with cookies or sessions is that you will potentially get false results under some circumstances, such as with tabbed browsing potentially. Another more accurate solution also involving the http://www.pmwiki.org/wiki/Cookbook/HttpVariables and a customization (patch to pmwiki) similar to the one done for the http://www.pmwiki.org/wiki/Cookbook/DynamicWikiTrails recipe. You could modify pmwiki to automatically add the current (i.e referring page as a GET value to every single link that pmwiki creates). Toward the end of the LinkPage function, add this line: $qf .= $qf ? "&":"?" . "PreviousPage=$pagename"; right before: $fmt = str_replace(array('$LinkUrl', '$LinkText'), array(PageVar($tgtname, '$PageUrl').PUE($qf), $txt), $fmt); return FmtPageName($fmt,$tgtname); } This is completly untested and is based on an older version of pmwiki, the LinkPage function may have changed slightly since then, but you should be able to get the idea from this. I hope this helps, Good luck, -Martin ____________________________________________________________________________________ Park yourself in front of a world of choices in alternative vehicles.
