I'd like to hide prices on product pages, cart and checkout as well as automatic e-mail only for certain product categories.
ChatGpt generated a code snippet (I used long thinking to make the code more effective) which works fine and does exactly what I want.
Are there any safety concerns?

So users are presented with multiple products on a single page, they can enter the quantity (also zero if they wish), then all of the products will be added to the cart.

Is this possible without a plugin?
