Kohana URLs

URLs in Kohana are composed of segments. A typical segmented URL is http://localhost/control/action/arg1/arg2

The segments correspond (in order ) to a controller, a controller method, and the method arguments.

Example

http://localhost/index.php/articles/edit/1/my-first-article
// or the same URL with url rewriting on
http://localhost/articles/edit/1/my-first-article

When you segmentize this url it becomes

• articles (the controller)
• edit (the action)
• 1 (first argument)
• my-first-article (second argument)

This will correspond to the controller articles found for example in application/controllers/articles.php - see Controllers for more information

The second segment maps to a method edit in the Articles_Controller class in application/controllers/articles.php If no second segment is set it will call the index() method. If a non-existing method is set it will try to call __call() or trigger a 404.

Note: You cannot pass arguments to an index method, unless the URI contains index in the second segment.

The third and fourth segment refer to arguments given to the edit() method. E.g. edit($id,$title)

An example of what a controller could look like when this url is used.

Example

class Articles_Controller extends Controller {
	function __construct(){
		parent::__construct();
	}
 
	function index()
	{
 
	}
 
	function edit($id,$title){
		//get the article from the database and edit it
		echo $id;
		$view = new View('articles/edit');
	}
}

As said, Kohana urls contain segments.

Example

http://localhost/articles/edit/1/my-first-article

Contains the segments

• articles
• edit
• 1
• my-first-article

A URI class and a URL helper provide methods to make working with a url easier. You can retrieve segments, determine the current url segment, and various other operations.

By default, Kohana urls contain index.php. This does not look very nice and also is not optimized for search engines. See the difference between the following urls.

http://localhost/index.php/articles/edit/1/my-first-article
// or the same URL with url rewriting on
http://localhost/articles/edit/1/my-first-article

The latter looks nicer and is SEO proof.

There is an example .htaccess included with Kohana, which should be part of your installation files.

Kohana allows you to set a suffix to your urls.

Example

http://localhost/index.php?/articles/edit/1/my-first-article.php

Setting this can be done in the application/config/config.php file under url_suffix

Query strings and GET support are enabled in Kohana. You can simply append your urls with ?var=value to pass it on. The keys and values are inspected and cleansed by the Input library when global_xss is on.
