For example, we want to know whether the cart contains a specific product.

First, get a product Array by split in Cart.liquid

Iterate the cart items, get variant ID in each loop. Check if the variant is the one we want.

{% assign gotIt = false %}
{% assign variantIds = "111, 222, 333" | split:", " %}

{% for item in cart.items %}
  {% assign itemVariantId = item.variant.id | downcase  %}
  {% for id in variantIds %}
    {% if id == itemVariantId  %}
      {% assign gotIt = true %}
    {% endif %}
  {% endfor %}
{% endfor %}

Or, you want to know if there’s a specific item in Checkout page.

The process is same with above codes.

Notice that you can get the variant_id from Checkout API, it’s in line_item.variant_id

{% assign gotIt = false %}

{% assign variantIds = "111, 222, 333" | split:", " %}

{% for line_item in checkout.line_items %}
  {% assign itemVariantId = line_item.variant_id | downcase  %}
  {% for id in variantIds %}
    {% if id == itemVariantId  %}
      {% assign gotIt = true %}
    {% endif %}
  {% endfor %}
{% endfor %}

And, you may also do the check by arr contains str grammer.
