Usage examples of the features is here:
Classic event handling requires one class with a bunch of methods named equal to event name.
And multiple $eventsManager->attach() calls if you use more than one handler for single event:
class DispatchEventsHandler { public function beforeCallActionMethod( Phalcon\Events\EventInterface $event, Phalcon\Dispatcher\DispatcherInterface $dispatcher ): void { //do some stuff } public function beforeDoSomeMistakes( Phalcon\Events\EventInterface $event, Phalcon\Dispatcher\DispatcherInterface $dispatcher ): void { //do some right stuff } } class DispatchEventsHandlerTwo { public function beforeCallActionMethod( Phalcon\Events\EventInterface $event, Phalcon\Dispatcher\DispatcherInterface $dispatcher ): void { //do another stuff in same event } } $eventsManager = new Phalcon\Events\Manager(); $eventsManager->attach('dispatch:beforeCallActionMethod',new DispatchEventsHandler(), 100); $eventsManager->attach('dispatch:beforeCallActionMethod',new DispatchEventsHandlerTwo(), 101); $eventsManager->attach('dispatch:beforeDoSomeMistakes',new DispatchEventsHandler()); //or global way $eventsManager->attach('dispatch',new DispatchEventsHandler(), 100); $eventsManager->attach('dispatch',new DispatchEventsHandlerTwo(), 101);This manager version provides a feature of single responsible event handlers via configs, using __invoke.
Create your handler class:
class BeforeCallActionMethod { public function __invoke( Phalcon\Events\EventInterface $event, Phalcon\Dispatcher\DispatcherInterface $dispatcher ): void { //do some stuff } }Define configuration in config file:
$config = new Phalcon\Config([ 'handlers' => [ 'dispatch:beforeCallActionMethod' => BeforeCallActionMethod::class, ], ]);Define Phalcon\Incubator\Events\Manager in container as eventsManager service using config of handlers:
$handlers = $config->get('handlers')->toArray(); $eventsManager = new Phalcon\Incubator\Events\Manager(); $eventsManager->loadHandlers($handlers);There are multiple ways to define configs of handlers:
Flat classname usage, if your handler is invokable:
$flat = new Phalcon\Config([ 'handlers' => [ 'dispatch:beforeCallActionMethod' => BeforeCallActionMethod::class, ], ]);Same, but more informative and with optional priority:
$verbose = new Phalcon\Config([ 'handlers' => [ 'dispatch:beforeCallActionMethod' => [ 'class' => BeforeCallActionMethod::class, 'priority' => 100, //optional ], ], ]);Using callable constructions:
$callable = new Phalcon\Config([ 'handlers' => [ //you can use any other public method name instead of method, for example run() 'dispatch:beforeCallActionMethod' => [new BeforeCallActionMethod(), 'run'], //or 'dispatch:beforeCallActionMethod' => [BeforeCallActionMethod::class, 'staticRun'], ], ]);Grouping more than one handler for one event:
$grouped = new Phalcon\Config([ 'handlers' => [ 'dispatch:beforeCallActionMethod' => [ BeforeCallActionMethod::class, BeforeCallActionMethodAnother::class, BeforeCallActionMethodThird::class, ], ], ]); $groupedVerbose = new Phalcon\Config([ 'handlers' => [ 'dispatch:beforeCallActionMethod' => [ [ 'class' => BeforeCallActionMethod::class, 'priority' => 100, //optional ], [ 'class' => BeforeCallActionMethodAnother::class, 'priority' => 101, //optional ], [ 'class' => BeforeCallActionMethodThird::class, 'priority' => 101, //optional ], ], ], ]);
