{if} ($product in $category) disable 'add to cart' {/if}

[MichaelMcG]

Hi there,

 

I'd like to be able to disable the 'Add to Cart' function on certain Categories.

 

How do I do this?

 

Is it something like this in my product.tpl:

{if} ($product in $category) // disable 'add to cart' {/if}

 

 

Many thanks for any pointers.
