Hide Quantity field for certain product ID?

[darren]

I need the help of someone with a superior brain to mine please.. In prestashop 1.7.6 I need to hide the quantity field for certain products (some have quantity as a combination) - I hoped i could add to the product.tpl something like..

{if $product_id=34}
<script type="text/javascript">
$(".bootstrap-touchspin").css( "display: none" );
</script>
{/if}

But this doesn't work - something similar DID work in PS 1.6, s I must be messing up somewhere. Any advise GREATLY appreciated!

did you find the div with class "qty" in product-add-to-cart.tpl? You should be able to use a similar syntax with $product

I'll have a look! Thank you so much for your help NemoPS.
