Which is the best entrance for a prizing discourse? When reply to a topic, will win a prize by chance, to attract more people to take part in

[jobsfan]

I am using laminas to build a project: a discourse kind system.

Our PM propose a function that publish a kind of topic(not all topic, just some choosen ones), when users reply to these topics, they may win a prize (a game activation code, etc) by chance.

To me, I want it to be decoupled to the main disourse logic. It should be a plugin-kind function.
It not break into the existing logic. And can be extented more such kind functions, and can be removed easily.

When a reply won the prize, this layer I mean this reply will have a special mark. Others will see the mark and take part in this topic.

I am considering where is the best entrance to place such extral function logic. registering some customed events like after_replied, or do these at the end of each controller action.

Any advises will be very much appreciated. Thank you!

You should use events here. See also this recent topic: Passing config into model

thank you!
I am trying to learn from your link.

Hi, long time no see!

I learned the link you pasted above. And learned that event may be the best way to approach the goal.

And also I have read Using the EventManager - tutorials - Laminas Docs several times.

Still I have problems to practise in my project.

1. I don’t know where to place the following code, in the Module.php?(I only found attach method in the onBootstrap() of Module.php file)

$events->attach('do', function ($e) {});

2. the PM said that, we may hold different activities(promotions) onside a topic. I am planning to write different classes for different promotion logics. each class encapsulate a concrete promotion logic. this way will provide flexibility to me. I can write anything inside the class.
   My question is that how to involve the promotion class(as well as promotion class instance) in/with the event stuff?

3. how to trigger the event after comment done. in another saying, where to place the trigger related code

$events->trigger('do', null, $params);

should I put it inside the CommentTable’s save() method?

Passing config into model

The whole system is a bit like a cross between a discussion forum and a mailing list. The Email\Model\EmailModel is a big long object that handles all email interactions. For example, when a new comment is made using CommentController it uses EmailModel to send the administrator a notification email. EmailModel is used from quite a few different Controllers to also handle sending out a bulk daily update email to subscribers. There isn’t much of an EmailController used. the Email module stores a…

You said it should decoupled with controller and action. inside the comment model you suggested. But I don’t know how. I am still looking forward to your example.

By the way, I got error when I followed the tutorial Using the EventManager - tutorials - Laminas Docs
My test code:

The error I got

Besides, when I wanna to typping the code by myself, I found in this page Quick Start - laminas-eventmanager - Laminas Docs

use Laminas\Log\Factory as LogFactory;

There is no Factory here, right after *Laminas\Log*
The phpstorm raise autocomplete Laminas\Log\Writer\Factory
