Checking if the product (also variants in color and size) is in cart?

[bloggus]

With the code below it is possible to check in tpl-file, if the products is already in cart, BUT this code do not take into the account variants of the products, like size or color.

        {if $product.quantity <= 0}
            {$in_cart = 0}
            {foreach from=$cart['products'] item='cart_product' }
            {if $cart_product['id_product'] == $product.id}
                {$in_cart = 1}
                {break}    
            {/if}
            {/foreach}
        {/if} 

 

Is is possible to alter the code so it also check if the size and color is in the cart? Not only check the product id?
