Hello,
Sorry for reopening such an old topic, but I stumbled upon this post when searching Google for the same result and thought I would post my complete solution that was never fully resolved in this post. So just in case anyone may search for it in the future, I will post the solution.
To add the subdomain segment to the beginning of the segments array, simply use "array_shift" and "array_unshift" before returning the segments.
Array_shift is used to remove the default controller from the beginning of the segments array if you are accessing the root of the subdomain (e.g. user.example.com).
Array_unshift is used to add the subdomain onto the beginning of the segments array.
Like this:
Code:
{
if (file_exists(APPPATH.'controllers/'.$http[0].EXT))
{
if($segments[0] == $this->default_controller) // Check if default controller and remove
{
array_shift($segments);
}
array_unshift($segments, $http[0]);
return $segments;
}
}
So the full MY_Router subclass will now be:
Code:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
/**
* Router Class
*
* Extends CI Router
*
* @author Original by EllisLab - extension by CleverIgniters
* @see http://codeigniter.com
*/
class MY_Router extends CI_Router {
/**
* Constructor
*
* @access public
*/
function MY_Router()
{
parent::CI_Router();
}
// --------------------------------------------------------------------
/**
* Validate Routing Request
*
* @access public
*/
function _validate_request($segments)
{
// CHECK TO SEE IF SUBDOMAIN AND GO ON FROM THERE
$http = explode('.', $_SERVER['HTTP_HOST']);
if(count($http) > 2)
{
if($http[0] != 'www')
{
if(is_dir(APPPATH.'controllers/'.$http[0]))
{
// Set the directory and remove it from the segment array
$this->set_directory($http[0]);
//$segments = array_slice($segments, 1);
if (count($segments) > 0)
{
// Does the requested controller exist in the sub-folder?
if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().$segments[0].EXT))
{
show_404($this->fetch_directory().$segments[0]);
}
}
else
{
$this->set_class($this->default_controller);
$this->set_method('index');
// Does the default controller exist in the sub-folder?
if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().$this->default_controller.EXT))
{
$this->directory = '';
return array();
}
}
return $segments;
}
else
{
if (file_exists(APPPATH.'controllers/'.$http[0].EXT))
{
if($segments[0] == $this->default_controller)
{
array_shift($segments);
}
array_unshift($segments, $http[0]);
return $segments;
}
}
}
}
//END SUBDOMAIN LOGIC HERE
// Does the requested controller exist in the root folder?
if (file_exists(APPPATH.'controllers/'.$segments[0].EXT))
{
return $segments;
}
// Is the controller in a sub-folder?
if (is_dir(APPPATH.'controllers/'.$segments[0]))
{
// Set the directory and remove it from the segment array
$this->set_directory($segments[0]);
$segments = array_slice($segments, 1);
if (count($segments) > 0)
{
// Does the requested controller exist in the sub-folder?
if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().$segments[0].EXT))
{
show_404($this->fetch_directory().$segments[0]);
}
}
else
{
$this->set_class($this->default_controller);
$this->set_method('index');
// Does the default controller exist in the sub-folder?
if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().$this->default_controller.EXT))
{
$this->directory = '';
return array();
}
}
return $segments;
}
// Can't find the requested controller...
show_404($segments[0]);
}
}
?>
Hope this helps
