Question

i know that everything is going through the controller.

but i often read articles that says something like this:

1. user interacts with the view
2. controller asks the model to change its state
3. model notifies the view when its sate has changed

i dont get the 3rd one. why saying that the model notifies the view, when it actually is notifying the controller and the controller is notifying the view?

Answer 1

That seems more like a desktop system and not a stateless system like a website.

But maybe it’s talking about how some people like to query the models from the view e.g.

<?php foreach( $usersTableGateway->getUsers() as $user ): ?>
<?php echo $user ?><br>
<?php endforeach; ?>

I’m more of a fan of getting all the info in the controller (preparing the users array in the controller) and passing it to the view from the controller.
