title: CodeIgniter: adding parameters to URL
body: <p>Started my first CI project and am just wondering how I handle URL parameters? I have a controller named 'city', and I've modified my mod_rewrite so localhost/codeigniter uses rewrite to localhost/codeigniter/city. What I want to do is add a city name onto the end of the URL and use get segment to query a table. </p>
  
  <p>So my example would be localhost/codeigniter/edinburgh. I would grab the last segment and then create the sql query. However I think when I put edinburgh into the URL CI thinks I'm looking for a controller called 'edinburgh'. </p>
  
  <p>Do I have to add routing in or something similar?</p>
