This is my way of remap in this scenario
In remap I check for existence of title - no spaces or dissallowed chars, use url_title(), and if error show 404.

Code:

function __construct()
   {
      parent::__construct();
      $this->load->model('page_model');
   }

   public function _remap($method, $params = array())
   {
      switch ($method)
      {  //I disallow ie do_ in the start of the title, to have other routes to controller
         case 'do_stuff':
         case 'do_other':
            if (method_exists($this, $method))
            {
               return call_user_func_array(array($this, $method), $params);
            }
            break;
         case 'index':
            return $this->index('home'); //my default page slug
         default:
            $query = $this->page_model->get_content($method)->row();
            if ($query)
            {
               return $this->index($method);
            }
            break;
      }
      show_404();
   }

   function index($slug)
   {
      $query = $this->page_model->get_content($slug)->row();
      if (!$query) {show_404();}
      // rest of code here
   }

thanks!
Please explain how did you do it?
I do not know how much, what we have in the model? (page_model)
Why are not variable cases?
Etc ...

[eluser]osci[/eluser]
I thought if you looked at the code as a workflow you would get the idea.

Code:

page_model->get_content($method)->row()

$method is the title request as it is returned by blog/title-request

get_content is your query for grabbing your content data and slug, like where tbl.title = 'slug'

Your index does the db stuff while they should be put in your model for MVC.

You should read a little about models and MVC in userguide

what do i do?

[eluser]osci[/eluser]
Your model is wrong.
You load view in model to display?
What is ->subject() ???
You don't pass the slug (title) in the function, in your model you ask for input->get(id)

I think you should read as I stated above about MVC.

[eluser]SaSa[/eluser]

The _remap function seems some functionality of CI to forward requests from one controller/action to another, and has nothing to do with URLs.
If you want to rewrite URLs you need mod_rewrite. This is not something that CI can do on it's own.

Did is this speech true?
Which is best(_remap or .htaccess) for rewrite URLs?

[eluser]danmontgomery[/eluser]
remap and htaccess are complicated (and not ideal) solutions for a simple problem. Use the routing functionality built into codeigniter.

http://ellislab.com/codeigniter/user-gui...uting.html

Code:

$route['blog/(:any)'] = 'blog_controller/some_method/$1';

Then just check for the slug which you store in the database along with the post

Code:

public function some_method($slug)
{
    $query = $this->db->where('slug', $slug)->get('blog_table');
    // etc
}
