CodeIgniter Routing Folder Error

On CodeIgniter 3 It does not allow you to have a sub folder on $route['default_controller'] you will instead need to create a MY_Router.php file like below.

You will need to create a MY_Router.php in

application > core > MY_Router.php

Here is a MY_Router.php file that should allow you to use $route['default_controller'] = 'public/pubweb'; in Codeigniter 3

<?phpclass MY_Router extends CI_Router {    protected function _set_default_controller() {        if (empty($this->default_controller)) {            show_error('Unable to determine what should be displayed. A default route has not been specified in the routing file.');        }        // Is the method being specified?        if (sscanf($this->default_controller, '%[^/]/%s', $class, $method) !== 2) {            $method = 'index';        }        // This is what I added, checks if the class is a directory        if( is_dir(APPPATH.'controllers/'.$class) ) {            // Set the class as the directory            $this->set_directory($class);            // $method is the class            $class = $method;            // Re check for slash if method has been set            if (sscanf($method, '%[^/]/%s', $class, $method) !== 2) {                $method = 'index';            }        }        if ( ! file_exists(APPPATH.'controllers/'.$this->directory.ucfirst($class).'.php')) {            // This will trigger 404 later            return;        }        $this->set_class($class);        $this->set_method($method);        // Assign routed segments, index starting from 1        $this->uri->rsegments = array(            1 => $class,            2 => $method        );        log_message('debug', 'No URI present. Default controller set.');    }}

Make sure your files have first letter upper case on file name and class name. Pubweb.php and class Pubweb extends CI_Controller {}

Hope this helps!

You can create a new file in the main controllers folder for routing purpose. for example, I have a directory structure like 'controllers/coming/Commingsoon.php'.if I want to run Commingsoon as my default controller so i will do this:

create new file in controllers folder: Main_controller.php:

class Main_controller extends CI_Controller{    public function __construct(){        parent:: __construct();    }    public function index(){            redirect('comming');     }} 

and in routes.php file:

$route['default_controller'] = 'main_controller';$route['comming'] = 'comming/commingsoon/index';

hope this will help...
