The goal is to split large business logic into smaller actions/task which are loosely decoupled, more readable, easy to maintain and quick to replace. ### Compatibility [](#compatibility) - PHP5.5+ Installation ------------ [](#installation) install the latest version via composer ``` composer require naucon/command ``` Usage ----- [](#usage) create CommandManager instance ``` $manager = new CommandManager(); ``` register commands to the manager instance ``` $manager->register('foo', new FooAction()); $manager->register('bar', new BarAction()); ``` execute command ``` $request = new FooRequest(); $response = $manager->execute($request) ``` create a request ``` class MyRequest { } ``` create a action (command) ``` use Naucon\Command\CommandInterface; class MyAction implements CommandInterface { /** * @param mixed $request * @return mixed response */ public function execute($request) { // do something .... return true; } /** * * @param mixed $request * @return bool returns true if request is support, else false */ public function support($request) { return $model instanceof MyRequest; } } ``` Data should be generally passed through the `Request` to the `Action`. ``` class PowerOnRequest { /** * @var Light */ protected $light; /** * Constructor * * @param Light $light */ public function __construct(Light $light) { $this->light = $light; } /** * @return Light */ public function getLight() { return $this->light; } } ``` To execute an `Action` within a `Action` the class requires an instance of the `CommandManager`. To inject the `CommandManager` implement the `CommandManagerAwareInterface` to the `Action`. The interface triggers the `CommandHydrator` to inject the `CommandManager` into the `Action` by calling `setCommandManager()`. The `CommandManagerAwareTrait` can be used to add property and setter. ``` class MyAction implements CommandInterface, CommandManagerAwareInterface { use CommandManagerAwareTrait; ... public function execute($request) { $request = new MySubRequest(); $response = $this->commandManager->execute($request); return $response; } ``` To inject other types of data into actions you can add custom processors to the `CommandHydrator`. Processor must implement the `ProcessorInterface`. Add a custom processor by calling `CustomerManager::addProcessor()`. Second argument is an optional `$priority` (`default = 0`). ``` $manager = new CommandManager(); $manager->addProcessor(new MyProcessor()); ``` In some rare cases with nested sub requests it can be necessary to break the workflow and immediately send a http response or redirect (generally not recommended). Therefore a `LogicException` that implements `ResponseInterface` can be thrown within the action (command). ``` use Naucon\Command\CommandInterface; use Naucon\Command\Response\HttpRedirect; class MyAction implements CommandInterface { /** * @param mixed $request * @return mixed response */ public function execute($request) { // do something .... throw new HttpRedirect($url, $statusCode, $headers); // or throw new HttpResponse($content, $statusCode, $headers); } ... ``` Example ------- [](#example) Start the build-in webserver to see the examples in action: ``` cd examples php -S 127.0.0.1:3000 ``` open url in browser ``` http://127.0.0.1:3000/index.html ``` Credits ------- [](#credits) This implementation was heavily inspired by the payum payment processing library. The modular and decoupled architecture can not only be used for processing payment it is also useful in many other use cases.
