Orphans & Wanted pages

http://www.dokuwiki.org/plugin:orphanswanted

Use this plugin to find orphan pages and wanted pages.

OrphansWanted show which pages are:

  • Orphans (the page exists, but it has no links to it)
  • Wanted (the page does not exist, but there are link(s) to it elsewhere on the site)
  • Valid (the page exists, and it can be reached through a link)

Each table shows the reference count.

Evolution

version 2.5beta

New version proposal : 2010-02-18, version 2.5beta.
Some changes to do it working with the “useslash” configuration option. Changes the function “orph_Check_InternalLinks()” to use more dokuwiki functions to avoid unevolutive code.
