检查产品是否在购物车中-Prestashop 1.7.4.2

Question

I'm facing a problem with prestashop 1.7.4.2 . I want to check if certain product ID is in cart before to allow customer proceeds checkout. If not, I want to display an alert.

In 1.6 , I could achieve this with :

{if !Context::getContext()->cart->containsProduct(784)}
message
{/if}

It doesn't work in 1.7.4.2 ...

Any help will be greatly appreciated ! Thanks a lot & cheers !

You can loop all products in $cart var :

{assign var="inCart" value=false}
{assign var="idProduct" value=YOUR_PRODUCT_ID}
{foreach from=$cart.products item=product}
    {if $product.id_product == $idProduct}
        {assign var="inCart" value=true}
    {/if}
{/foreach}

{if $inCart == true}
    idProduct is cart !
{/if}
