title: Form Actions in Codeigniter gets added to the existing URL
body: <p>I am new to codeigniter and i am facing a small issue. I have a controller named "test" and would like to call the "edit_details" action within that controller. This is a test application i am developing. I would like to update a user's information and i am sending the user id via(URL segments) the URL: "http://localhost/codeigniter/index.php/test/edit/12" as an example. The edit action loads the view with a form where the user's details could be entered. This is done using an anchor from the view(an edit link next to each record). Anchor: "test/edit/$row->id". Everything so far works great.</p>
  
  <p>The problem is when i submit the form with the action 'test/update_details', the url then becomes "http://localhost/codeigniter/index.php/test/edit/test/update_details'". The edit_details action loads a model which then does the database stuff. The id is sent using a hidden field in the view.</p>
  
  <p>I am not sure what is going wrong here. The URL doesnt seem to change when i make calls to a controller. It either stays the same or gets appended to the existing URL. I have tried google to search for a solution but couldnt find any. </p>
  
  <p>I still havent removed my index.php as this is a test application.
  My base url in the config file is : "http://localhost/codeigniter/"
  Autoloaded helpers are: form and url
  Autoloaded libraries are: database</p>
  
  <p>Thanks in advance.</p>
