Examples of snippets using Liquid

The following are some example Liquid snippets supported by Checkout Blocks.

Check if checkout is B2B

You can display content only when the checkout is B2B.

{%- if customer.b2b -%}
B2B
{%- endif -%}

Parse JSON

You can parse JSON values, such as from line item attributes (properties) or metafields.

{%- assign complex_json = checkout.metafields.checkoutblocks.complex | json -%}

Format currency

Checkout Blocks fully supports multi-currency checkout. Simply pass the money filter to parse and format money using the active currency format. This doesn't automatically convert the currency.

{{ checkout.total_price | money }}

Cart note

You can display the value of the cart note, such as what was entered on the cart.

{{ checkout.note }}

Cart attributes

To display the value of a particular cart attribute, such as a delivery date, you can use this snippet. Be sure to change the key Delivery date to match your own.

{% assign delivery_date = '' %}
{% for attribute in checkout.attributes %}
  {% if attribute.key == 'Delivery date' %}
    {% assign delivery_date = attribute.value %}
  {% endif %}
{% endfor %}

Delivery Date: {{ delivery_date }}

Display entire checkout Liquid contents

If you need to review what values exist on the checkout object, then you can using JSON filter to serialize. This should only be used for debugging purposes.

{{ checkout | json }}

Checkout metafields

You can display custom fields saved to checkout on the thank you and order status pages by referencing the checkout metafields. Learn more about accessing metafields.

Replace your-namespace with your namespace and your-custom-field-key with your custom field key as defined on the block:

{{ checkout.metafields.your-namespace.your-custom-field-key.value }}

Format a date

In this example, we create a date 4 days in the future (432000 seconds) and then format it.

You can return the date formatted as "02/24/2025":

{% assign future_date = "now" | date: "%s" | plus: 432000 %}
{{ future_date | date: "%m/%d/%Y" }}

Alternatively, you can format the date as "Feb 24, 2025":

{% assign future_date = "now" | date: "%s" | plus: 432000 %}
{{ future_date | date: "%b %d, %Y" }}

Line item content customizations

Plan requirement

Creating a line item content block is available only to merchants on the Shopify Plus plan.

The following are some example Liquid snippets you can use on Line item content blocks.

Conditionally show the compare at price

You can conditionally show a line item's compare at price using this snippet.

{%- if line_item.variant.compare_at_price.amount -%}
On sale. Originally {{ line_item.variant.compare_at_price.amount | times: line_item.quantity | money }}
{%- endif -%}

Display content based on product tags

You can conditionally display line item content based on the product tags, which are case sensitive.

{%- if line_item.product.tags contains 'final-sale' -%}
Final sale
{%- endif -%}

Line item attributes (properties)

You can iterate over line item attributes, also known as line item properties, and display information such as delivery estimates, pre-orders, and more.

{%- assign first_line_attribute = line_item.attributes | first  -%}
{%- assign first_attribute_value =  first_line_attribute.value | json_parse  -%}
{%- assign message =  first_attribute_value.message -%}
{%- if message -%}
  {{ message }}
{%- endif -%}

Display the "metafield trigger" value

The following code will contain the value of the trigger.

{{ line_item.trigger }}

Show recurring total for a line item

If you need to show the recurring total for a subscription line item before one-time discounts, then you can use the line_level_total_discount value.

{%- if line_item.line_level_total_discount > 0 and line_item.has_selling_plan -%}
Recurring total: {{ line_item.line_price | plus: line_item.line_level_total_discount | money }}
{%- endif -%}
