We used the tag plugin for dokuwiki. Installing this (and its pre-requisite plugins, feed and pagelist) was easy.
Initially I couldn't get the topic feature (that shows pages with a tag) to work - it resulted in a blank page. This was traced to curl not being installed. Doh!
The easy fix was (detailed at the curl site):
- Get the required binaries (php_curl.dll, libeay32.dll and ssleay32.dll).
- Ensure the latter two binaries are in the PATH.
- Uncomment the curl extension in php.ini.
