Extension: get activities of all users in a category — get the experts

15. Oktober 2008 – 12:21

Who is the expert of a category? Maybe who is writing at most there?! Anyhow, he knows a lot about the topic, if he is the most frequent editor. To find the most frequent editors, i have written a little extension, that uses Googles Chart API to show user edits within all articles in the category (recursive from current category to all leafs).

get it

getExperts.php
(the code is ugly at the moment! — many sql queries)

install it

put the php file in the extensions folder
add to the LocalSettings.php this:
require_once( “$IP/extensions/getExperts.php” );

how to use

place a new tag <allpages/> on any categories page

alternatives

SWFcharts PHP/SWF Charts offers a simple and dynamic solution for interactive Flash-based charts. Columns, circles, bars and pies can be displayed in 3D. You create an XML source to describe a chart, then pass it to this tool’s flash file to generate the chart.
