Default Controller not loading after rerouting

What you appear to be doing is looking for a controller with the 'sitename' you are passing through. So if you navigate to site.com/sites/my-site/ you route tells it to look for a controller called my-site and run the index method.

The value of the route should be a path to an actual controller / method pair.

$route['sites/([^/]+)/(.*)'] = '$2';

should be

$route['sites/([^/]+)/(.*)'] = 'sites/index/$1/$2';

This is assuming it's the index method that accepts the sitename as it's first parameter in your sites controller.

It's not totally clear what you're asking, but heres a shot:

You need to create an .htaccess file in the root of your site (i.e. in the same folder that your system folder is in). In that file:

<IfModule mod_rewrite.c>RewriteEngine onRewriteCond $1 !^(index\.php)RewriteRule ^(.*)$ index.php/$1 [L]</IfModule>

See the "Remove the index.php file" section of this page: http://codeigniter.com/user_guide/general/urls.html for more info.

Also, the route that you're using would make it so that when you go to www.site.com, you will see www.site.com/sites/content.

With the url www.site.com/sites/sitename/content/, sites is your controller, sitename the method or function, and content would be considered a parameter to the sitename function -- this won't work like it seems like you want, but I can't be sure without seeing your controller.

Maybe edit your question and add your controller(s), and we can be of more assistance.

UPDATE:

1: $config['base_url'] has nothing to do with routing or which controller is being used, so this is making your question harder to understand.

2: It isn't clear what you are trying to accomplish (sorry).

By idea when I go to

www.site.com/sites/sitename/

the default controller is not loading.

According to the CI user guide:

CodeIgniter can be told to load a default controller when a URI is not present, as will be the case when only your site root URL is requested. To specify a default controller, open your application/config/routes.php file and set this variable:

So, what this means is that the default_controller is used only when there is no URI present. In other words: the default controller only applies when the URL is www.site.com, and in no other case will it be used (unless you are using sub-folders in the controllers folder -- see below).

If you trying to make it so that each of your sites has its' own controller, you could use subfolders in your controller folder.

In routes.php:

$route['sites/(:any)'] = "$1";$route['default_controller'] = "content";

Then your folder structure:

So you have your controller folder. In it, create a folder for each site. In each of those controllers create your default controller (named content.php in the above image).

With this setup, www.site.com/sites/site1 will call the default controller (content) from application/controllers/site1/content.php and show the index function of that controller.

If you then want to call other functions of the site1 controller, the URL would look like:www.site.com/sites/site1/content/otherFunction.

Hope this helps.

$uri_string=$_SERVER['REQUEST_URI'];                    $way=explode('/',$uri_string);                       /// print_r($way);//echo $way[3];                        if($way[1]=="sites" and strlen($way[2])>2 and strlen($way[3])<1){                            echo "JAJA ";$route['sites/:any'] = "content/show_page/home";                        }                        else{                           $route['sites/([^/]+)/(.*)'] = '$2';                        }

this was solution. thanks all who answered. thanks stormdrain. you pointed me to a write direction in your routing example. Thanks
