Example

Kirby's objects are immutable. That means, when you modify an object like $page, $file etc. using a method like update(), changeTitle() and so on, a new object is returned. Therefore, you have to store the returned object in a new variable to be able to further work with it.

<?php $page->decrement('likes') ?>
