Cart Items Total to include qty of variants

Question

By using line total: {{ cart.lineItems|length }} it returns the number of 'products' in the current sessions cart. However, this doesn't seem to take into account the qty of each variant.

So if I add 3 of variant A and 2 of variant B, the lineItems|length would equal 2. But I want to cart to show there are 5 items added.

How can I get the total of all the items in the cart including qty of each variant?

Answer 1

You can get the total quantity of items with:

cart.totalQty

Answer 2

After working on this for a while and the help of a fellow developer. The following solution seems to work. Unless anyone can improve on it?

{% set cartQty = 0 %}
{% for item in cart.lineItems %}
    {% set cartQty = cartQty + item.qty %}
{% endfor %}
