DrF Reverse Routing

DrF Reverse Routing is an extension of the URL Helper that overrides the site_url function to provide a reverse lookup. If a custom route can be found that matches the given "standard CodeIgniter URI", a custom route URI will be created and returned. Otherwise, a standard site_url will be returned.

[h2]Overview[/h2]

• Translates a "standard CodeIgniter URI" into a custom route if possible. Standard, in this case, means [em]controller/function/param1/param2/.../paramN[/em]
• Fails gracefully, providing a standard site_url if no route can be found/translated
• Works automatically with all of URL Helper's functions
• Idea inspired by CakePHP's reverse routing

[h2]Usage[/h2]

• place MY_url_helper.php in your system/application/helpers folder
• include the URL helper in your controller [code]$this->load->helper( 'url' );[/code]
• use URL Helper's functions as you normally would

[h2]Example[/h2]

• setup a Test Controller [code] <?php class Test extends MY_Controller{

  function Test() { parent::MY_Controller(); }

  function test( $param1 ){ echo 'You passed in: ' $param1; }

  function redirect() { $this->load->helper( 'url' ); redirect( 'test/test/bar' ); }

} ?> [/code]

• create a route for the test function [code] ... $route['foo/(:any)'] = 'test/test/$1'; ... [/code]
• Go to [b]http://www.example.com/test/redirect[/b]. Replace example.com with your server name
• You should be redirected to [b]http://www.example.com/foo/bar[/b]
