Route to multiple sub folders in CodeIgniter

This code was already on the internet but i modified it to make it work for codeigniter 2.1

See the old source here: http://glennpratama.wordpress.com/2009/10/20/multi-level-subfolder-for-controller-in-codeigniter/

Make a new file MY_Router.php in the application/core directory, copy the following code in it:

<?php/* * Custom router function v 0.2 * * Add functionality : read into more than one sub-folder * */Class MY_Router extends CI_Router{    Function MY_Router()    {        parent::__construct();    }    function _validate_request($segments)    {        if (file_exists(APPPATH.'controllers/'.$segments[0].EXT))        {            return $segments;        }        if (is_dir(APPPATH.'controllers/'.$segments[0]))        {            $this->set_directory($segments[0]);            $segments = array_slice($segments, 1);            /* ----------- ADDED CODE ------------ */            while(count($segments) > 0 && is_dir(APPPATH.'controllers/'.$this->directory.$segments[0]))            {                // Set the directory and remove it from the segment array            //$this->set_directory($this->directory . $segments[0]);            if (substr($this->directory, -1, 1) == '/')                $this->directory = $this->directory . $segments[0];            else                $this->directory = $this->directory . '/' . $segments[0];            $segments = array_slice($segments, 1);            }            if (substr($this->directory, -1, 1) != '/')                $this->directory = $this->directory . '/';            /* ----------- END ------------ */            if (count($segments) > 0)            {                if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().'/'.$segments[0].EXT))                {                    show_404($this->fetch_directory().$segments[0]);                }            }            else            {                $this->set_class($this->default_controller);                $this->set_method('index');                if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().'/' .$this->default_controller.EXT))                {                    $this->directory = '';                    return array();                }            }            return $segments;        }        show_404($segments[0]);    }}

"Out of the Box" codeigniter does not support multiple subdirectory levels in your controllers directory, just one.

There is a way to extend the routing class to support this, check this blog entry.

For Codeigniter 3.x compatibility: The usage of the EXT constant has been deprecated since dropping support for PHP 4. There’s no longer a need to maintain different filename extensions and in this new CodeIgniter version (3.x), the EXT constant has been removed. Use just ‘.php’ instead.

So the new MY_Router.php:

<?php/* * Custom router function v 0.3 * * Add functionality : read into more than one sub-folder * Compatible with Codeigniter 3.x * */Class MY_Router extends CI_Router{    Function MY_Router()    {        parent::__construct();    }    function _validate_request($segments)    {       if (file_exists(APPPATH.'controllers/'.$segments[0].".php"))        {            return $segments;        }        if (is_dir(APPPATH.'controllers/'.$segments[0]))        {            $this->set_directory($segments[0]);            $segments = array_slice($segments, 1);            /* ----------- ADDED CODE ------------ */            while(count($segments) > 0 && is_dir(APPPATH.'controllers/'.$this->directory.$segments[0]))            {                // Set the directory and remove it from the segment array            //$this->set_directory($this->directory . $segments[0]);            if (substr($this->directory, -1, 1) == '/')                $this->directory = $this->directory . $segments[0];            else                $this->directory = $this->directory . '/' . $segments[0];            $segments = array_slice($segments, 1);            }            if (substr($this->directory, -1, 1) != '/')                $this->directory = $this->directory . '/';            /* ----------- END ------------ */            if (count($segments) > 0)            {                if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().'/'.$segments[0].".php"))                {                    show_404($this->fetch_directory().$segments[0]);                }            }            else            {                $this->set_class($this->default_controller);                $this->set_method('index');                if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().'/' .$this->default_controller.".php"))                {                    $this->directory = '';                    return array();                }            }            return $segments;        }        show_404($segments[0]);    }}
