Try the beta version of the new SilverStripe documentation

For the next 2 weeks you can use the new documentation website and give us your feedback.


This document contains information for an outdated version (2.3) and may not be maintained any more.

If some of your projects still use this version, consider upgrading as soon as possible.


Base controller class. You will extend this to take granular control over the actions and url handling of aspects of your SilverStripe site.



class FastFood_Controller extends Controller {
    function order($arguments) {


Director::addRules(50, array('fastfood/$Action/$ID/$Name' => 'FastFood_Controller'));

Request for '/fastfood/order/24/cheesefries' would result in the following to the $arguments above. If needed, use "?flush=1" on the end of request after making any code changes to your controller.

    [Action] => order
    [ID] => 24
    [Name] => cheesefries

URL Handling

In the above example the URLs were configured using the Director rules in the _config.php file. Alternatively you can specify these in your Controller class via the $url_handlers static array (which gets processed by the RequestHandler).

This is useful when you want to subvert the fixed action mapping of 'fastfood/order/*' to the function order. In the case below we also want any orders coming through '/fastfood/drivethrough/' to use the same order function.


class FastFood_Controller extends Controller {
    public static $url_handlers = array(
            'drivethrough/$Action/$ID/$Name' => 'order'

URL Patterns

The RequestHandler class will parse all rules you specify against the following patterns.

A rule must always start with alphabetical ([A-Za-z]) characters or a $Variable declaration

Pattern Description
$ Param Variable - Starts the name of a paramater variable, it is optional to match this unless ! is used
! Require Variable - Placing this after a parameter variable requires data to be present for the rule to match
// Shift Point - Declares that only variables denoted with a $ are parsed into the $params AFTER this point in the regex


See maetl's article in the Links below of a detailed explanation.

$Action/$ID/$OtherID - Standard URL handler for a Controller. Take whatever URLSegment it is set to, find the Action to match a function in the controller, and parse two optional $param variables that will be named ID and OtherID.

admin/help//$Action/$ID - Match an url starting with /admin/help/, but don't include /help/ as part of the action (the shift point is set to start parsing variables and the appropriate controller action AFTER the //)

tag/$Tag! - Match an URL starting with /tag/ after the controller's URLSegment and require it to have something after it. If the URLSegment is order then /order/tag/34 and /order/tag/asdf match but /order/tag/ will not

You can use the debug_request=1 switch from the urlvariabletools to see these in action.
