Docs for new hooks?
Developer Preview
Maybe I’m not looking in the right place, but I don’t see anything on what has been updated in 3.1 for the hooks. I’m seeing the forwardEventsToHooks() method, which looks like I should be subscribing to events instead of adding rows to the exp_extensions table? Is there some place else I should be looking for direction on the best approach for EE3?
I see this page in the docs, but it looks like all the old hooks. Are these still the preferred approach? /development/extension_hooks/index.html
After some digging around I found some of the old hooks and was able to get one of the new entry save hooks implemented.
The event documentation seems to be lacking as well. E.g. it shows how to create a subscriber and publisher, but it doesn’t really provide a real use case. If I want to subscribe to a native event, where do I register the subscriber? The best I could figure is in the ext constructor. Am I approaching this incorrectly?
public function __construct()
{
$emitter = ee('Event');
$emitter->subscribe(new MySubscriber());
}
The new hooks are documented under the Models section at development/extension_hooks/index, hope that helps. I’ll ask Pascal to see if he can help you with the Event service.
Kevin is correct. The old hook approach is still the preferred one for those times where you want to subscribe to one of the core events (aside from model-to-model interaction, where a relationship is the way to go). We automatically connect the model events to the old hooks using that method you found. The event service could be used to re-implement extensions for roughly the same functionality, but we haven’t done that yet.
So I suppose some of the confusion comes from the fact that there is no global singleton event bus. If you’re trying to create one that is global to your add-on, this should work:
// addon.setup.php
'services.singletons' => array(
'Event' => function($addon) {
return $add->make('ee:Event');
}
)
// usage:
ee('myaddon:Event')Can you elaborate on what you’re trying to do?
