CodeIgniter Routing Folder Error

问题:

I have the CodeIgniter controller file, placed in here

controllers/public/Pubweb.php

and I want to set that file as my default controller, but when I change the default controller route value, it will goes error. My route code :

$route['default_controller'] = 'public/pubweb';

Can someone help me?

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

<?php

class 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...
