Show product flag "Product is already in cart" in product-list

[dianacd]

Hello there, 

I am new developer in Prestashop, I use Prestashop 1.7

 

I added a sold out flag when product quantity is 0 with the following code:

 

    {if $product.quantity==0}
        <li>
            <img src="soldout.png" style="position:absolute;max-width:65px" />
        </li>
    {/if}

But when the customer adds the product to the cart (if the only quantity available is 1) the sold out label will be shown in the product list.

I would like to instead, show a flag that says "Already in cart" in this case but I am not sure how to verify if the current product is on cart.

 

Someone has any idea in how to do the condition to verify current product is in cart?

 

Thanks!
