Question

I have a codeigniter multistie install where I have such code that I can serve sites with such links

site.com/sites/sitename/controller/function/vars
site.com/controller/function/vars/

subdom.site.com/controller/function/vars

the challange is that , whith the routing

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

I get working the links like

site.com/sites/sitename/controller/function/vars
site.com/controller/function/vars

By idea when I go to

http://www.site.com/sites/sitename/

the default controller is not loading.

I made the config.php so that regarding the link structure, when I visit link

site.com/sites/sitename/controller/function/vars

then

$config['base_url']="http://site.com/sites/sitename";

if I go to

site.com/controller/function/vars

then

$config[‘base_url’]=”http://site.com/”;

for the second case the default controller loads perfectly. For the subsite case not/

I get just 404

What to do?

UPDATE 2:

I have a multifolder setup.

When user goes to http://www.site.com/sites/site_name

then a folder of application

/root_folder/usersites/site_name is loaded.

When user goes just site.com/controller/function/var1/var2

a default application folder which is

/root_folder/application is loaded

when user goes to sub1.site.com application folder

/root_folder/domains/sub1_site_com is loaded

So when I enter in address bar

http://site.com/sites/site_name

it should be like no URI. and should load default controller.

    // Application folder loading code
$myApp = '';


if($_SERVER['SERVER_ADDR']=='127.0.0.1'){
    $main_url='site.com';
}
else{
    $main_url='site1.com';
}

//echo $main_url;

switch($_SERVER['HTTP_HOST'])
{
    case $main_url;




        $uri_string=$_SERVER['REQUEST_URI'];
                    $link_way=explode('/',$uri_string);

        if(strlen($uri_string)>6 and $link_way[1]=='sites' ){



            //print_r($link_way);
            //var_dump($link_way);

            //checking if the link goes to usersites and sitename is bigger and =5
            if($link_way[1]=='sites' and strlen($link_way[2])>=5){


                $myApp='sites/usersites/'.$link_way[2];
                define('SITE_ALIAS','1|'.$link_way[2]);


                }
            elseif($link_way[1]=='sites' and strlen($link_way[2])<5){
                exit('Username should be more than 4 chars');

                }






            }

        else{

                        define('SITE_ALIAS','0|'.str_replace('.','_',$_SERVER['HTTP_HOST']));


        $myApp = 'application';
                }




        break;

     default:
        $myApp = str_replace('.','_',$_SERVER['HTTP_HOST']);
        $myApp=str_replace('www_','',$myApp);
                 define('SITE_ALIAS','2|'.$myApp);
        $myApp='sites/domains/'.$myApp;



    }

$application_folder = $myApp;

Answer 1

$uri_string=$_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
