In the original Kohana wiki application the URLs in the views were hardcoded. If we wanted to change the domain name or restructure a route we would need to go through the application and change every single URL.

Thankfully the Kohana Route class comes with a method url() which allows us to generate URLs to routes we have specified in the application. In the first tutorial we defined the following routes in application/bootstrap.php:

Route::set('wiki-edit', 'wiki/<page>/edit')
	->defaults(array(
		'controller'=> 'wiki',
		'action'	=> 'edit_page',
	));

Route::set('wiki-save', 'wiki/<page>/save')
	->defaults(array(
		'controller'=> 'wiki',
		'action'	=> 'save_page',
	));

Route::set('wiki-page', 'wiki/<page>')
	->defaults(array(
		'controller'=> 'wiki',
		'action'	=> 'view_page',
	));

Route::set('default', 'wiki')
	->defaults(array(
		'controller' => 'wiki',
		'action'     => 'view_page',
		'id'		 => 'index',
	));

Before we can generate routes we need to set some configuration options in application/bootstrap.php (line ~82). We need to specify the base_url and index_file attributes in the array passed to Kohana::init(). The application on my local install is located at 127.0.0.1/query7kwiki/index.php, so my Kohana::init() statement would read:

Kohana::init(array(
	'base_url'   => '/query7kwiki/',
	'index_file' => 'index.php'
));

In application/views/edit.php the form action attribute was hardcoded to the value /query7kwiki/index.php/wiki/. That can be replaced by:

<?php echo Route::url('wiki-save', array('page' => $page)); ?>

In application/views/single.php there is a link to the edit that specific page. We can replace the href of the anchor tag with:

<?php echo Route::url('wiki-edit', array('page' => $page)); ?>

In the view application/views/create.php change the href of the create page link to:

<?php echo Route::url('wiki-edit', array('page' => $page)); ?>

The wiki application is now portable and can safely be moved to a different server without functionality breaking.
