How to get the number of products inside cart in shopify?

To get the number of products inside the cart in Shopify, you can use the Shopify Liquid template language.

1. Open your Shopify Theme Editor.
2. Locate the file where you want to display the number of products in the cart (common places include header or cart page).
3. Check if there is an existing cart object available. You can usually find it by searching for the {% cart %} tag.
4. If the cart object is available, you can use the item_count attribute to get the number of products in the cart.

Here is an example code snippet to display the number of products in the cart:

1
2
3
4
5

{% if cart.item_count > 0 %}
   <p>{{ cart.item_count }} items in your cart</p>
{% else %}
   <p>Your cart is empty</p>
{% endif %}

This code will display the number of items in the cart if it is greater than 0. Otherwise, it will display a message indicating an empty cart.
