As you can see at the demo,

there is a section which shows "other products in the same category" using the "Field product cate" module.

Can I disable it for 0 products using a condition and, if yes, can you show me how?

Hi. I haven't used anything yet.

I was wondering if there could be a {condition} to add to the "Field product cate" module template to check for 0 products.

But any solution you can recommend is welcome.

Thank you for showing me that.

The title "0 other products in the same category" appears because just above the code line that you marked, there is a check -for the title only- like this:

{if $categoryProducts|@count > 1}
{$categoryProducts|@count} {l s='other products in the same category' mod='fieldproductcates'}
{else}
{$categoryProducts|@count} {l s='other product in the same category' mod='fieldproductcates'}
{/if}

So I just need to remove the {else} part.

Problem solved. :)
