Question

Hi i wont to make something like that.

http:// example.com/ - Main Controller

http:// example.com/rules/ - Main Controller where content get from database, but if not exist return 404 page. (It's ok, isn't problem.)

But if i have subfolder in application/controlles/rules/ I want to redirect it to Main Contorller at Rules folder.

This follow code can solve problem, but i don't know how it right realise. At routes.php:

$route['default_controller'] = "main";
$route['404_override'] = '';

$dirtest = $route['(:any)'];

if (is_dir(APPPATH.'controllers/'.$dirtest)) {
$route['(:any)'] = $dirtest.'/$1';
} else {
$route['(:any)'] = 'main/index/$1';
}

---

Ok, what I have:

controllers/main.php

class Main extends CI_Controller {

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

    public function index($method = null)
    {
        if (is_dir(APPPATH.'controllers/'.$method)) {
            // Need re-rout to the application/controllers/$method/
        } else {
            if ($query = $this->main_model->get_content($method)) {
                $data['content'] = $query[0]->text;
                // it shows at views/main.php
            } else {
                show_404($method);
            }
        }
        $data['main_content'] = 'main';
        $this->load->view('includes/template', $data);
    }

}

Updated Again (routes.php): So, seem's like what i search (work example):

$route['default_controller'] = "main";
$route['404_override'] = '';


$subfolders = glob(APPPATH.'controllers/*', GLOB_ONLYDIR);

foreach ($subfolders as $folder) {
    $folder = preg_replace('/application\/controllers\//', '', $folder);
    $route[$folder] = $folder.'/main/index/';
    $route[$folder.'/(:any)'] = $folder.'/main/$1';
}

$route['(:any)'] = 'main/index/$1';

But, in perfectly need some like this:

http:// example.com/1/2/3/4/5/6/...

1. Folder "controllers" has subfolder "1"?
2. YES: Folder "1" has subfolder "2"?
3. NO: Folder "1" has controller "2.php"?
4. NO: Controller "controllers/1/main.php" has function "2"?
5. YES: redirect to http:// example.com/1/2/ - where 3,4,5 - parameters..

It is realy nice, when you have structure like:

http://example.com/blog/ - recent blog's posts
http://example.com/blog/2007/ - recent from 2007 year blog's posts
http://example.com/blog/2007/06/ - same with month number
http://example.com/blog/2007/06/29/ - same with day number
http://example.com/blog/web-design/ - recent blog's post's about web design
http://example.com/blog/web-design/2007/ - blog' posts about web design from 2007 years.
http://example.com/blog/current-post-title/ - current post

I didn't thoroughly read your question, but this immediately caught my attention:

if (is_dir($path . '/' . $folder)) {
    echo "$route['$folder/(:any)'] = '$folder/index/$1';"; //<---- why echo ???
}

Honestly I'm not sure why this didn't cause serious issues for you in addition to not working.

You don't want to echo the route here, that will just try to print the string to screen, it's not even interpreted as PHP this way. There are also some issues with quotes that need to be remedied so the variables can be read as variables, not strings. Try this instead:

if (is_dir($path . '/' . $folder)) {
    $route[$folder.'/(:any)'] = $folder.'/index/$1';
}

Aside: I'd like to offer some additional resources that are not directly related to your problem, but should help you nonetheless with a solution:

• Preferred way to remap calls to controllers: http://codeigniter.com/user_guide/general/controllers.html#remapping
• Easier way to scan directories: http://php.net/manual/en/function.glob.php
