The commandpattern module enables SilverStripe to decouple business logic from the MVC structure. Commands can be executed individually and have a reference to a calling controller.

To install this module, please clone this module, copy the commands folder into the root folder of the SilverStripe installation and run a dev/build, i.e.:


The module consists of a Factory-class which will be used to request command actions. The factory class initiates the command and returns the command object to the calling method, i.e.:

$command = CommandFactory::get_command('Test');

This call will return initiate a TestCommand object and returns the instance. get_command also accepts two optional parameters:

  • first parameter is a reference to the calling controller instance (@link Controller).
  • second parameter is a associated array for parameters.


We want to create a command with takes two integer ('x' and 'y') values and when executing the command, it will return the result of x * y.

First create the command class in your project folder:

class TestCommand extends ControllerCommand {

	public function execute() {
		$data = $this->getParameters();
		$x = $data['x'];
		$y = $data['y'];
		return (int)$x * (int) $y;

Installation Instructions

Add this module into your project folder (name mapping) and run a dev/build to generate the required database schema.

Usage Overview

Implements the command pattern for SilverStripe controllers. This enables the developers to move core business logic into a dedicated command class.

Ideal for de-coupling MVC from core business domain related logic.
