I have a URL like http://example.com/arbitrary/path that I would like to map to a specific template file. At the moment I am achieving this by enabling permalinks and creating the pages "arbitrary" and "path" (page "arbitrary" is set to parent of "path") then choosing a custom template. The downside to this is that the client could delete these pages thus breaking the site.
Anyone know of a better way? Like something I could add to functions.php.
