rewrite rule for codeigniter - apache

Question

this is my controller in CI
class Welcome extends Controller {
function Welcome()
{
parent::Controller();
}
function index()
{
}
function bil($model='')
{ }
I want to do a rewrite so that
http://example.com/index.php/welcome/bil/model
becomes
http://example.com/model
in my htaccess I have
RewriteBase /
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/welcome/$1 [L]
#RewriteRule ^(.*)$ /index.php/welcome/bil/$1 [L]
I thought it should be as easy as removing the /index.php/welcome/ part
but when I uncomment the last line it get 500 internal server error

You'll want to use mod_rewrite to remove your index.php file like you have above, but use CodeIgniter's routing features to reroute example.com/model to example.com/welcome/bil/model.
In your routes.php configuration file, you can then define a new route like this:
// a URL with anything after example.com
// will get remapped to the "welcome" class and the "bil" function,
// passing the match as a variable
$route['(:any)'] = "welcome/bil/$1";
So then, typing example.com/abc123 would be equivalent to example.com/welcome/bil/abc123.
Note that only characters permitted by $config['permitted_uri_chars'] (which is located in your config.php file) are allowed in a URL.
Hope that helps!
