How to hide blocks in certain opencart blog categories?

Question

PHP

Hello!
Friends, help with advice on how to do it right. There is an opencart website. The idea is to show a brief description of the article in some categories of the blog (news) and not in others. I understand that I need to make an output condition by category id, but I can’t figure out how to do it =((One kind person suggested that you need to check the id in the controller and create a variable for the necessary one, thanks to which the necessary sections should be displayed in the template file. I got completely confused

Answer 1

Decided so, again, a kind person suggested how:
In the controller
In the template file we wrap

<?php if (!$ne_pokazivat) { ?>нужный участок кода<?php } ?>
