What is the best way to handle the +count button?

Question

Laravel

I have posts that by default cost 1 + 3 and, accordingly, when clicked, I would like to add +3 values ​​each.
It turns out that I just need to add values ​​to limit() through a button? I work simply through ORM and I don’t understand a little whether it’s advisable to do this at all or not.
