I'd like to add an extra 'non-functional' url segment in front of the next url segments
e.g. I now have a url http://www.domain.com/news/newspost1/ but I'd like to add a cityname in front of the url so like this: http://www.domain.com/cityname/news/newspost1/
That way I can request which cityname it is on the page.
I've been fiddling with add_rewrite_rule() in wordpress but I can't seem to get it to work.
Any ideas?
