Understanding and Using Shopify Liquid Filters

Shopify Liquid filters are essential tools in the Shopify templating language, allowing developers and store owners to modify default objects, variables, and strings directly in their store’s theme. This guide will explore the functionality of various Shopify Liquid filters, demonstrating how they can be used to improve data presentation and manipulate content dynamically.

What Are Liquid Filters? Liquid filters are simple methods that modify the output of numbers, strings, objects, and variables in Liquid, the templating language used by Shopify. They are used within an output tag and are denoted by a pipe character (|).

Using Shopify Liquid Filters Here are some commonly used Liquid filters and how to implement them in your Shopify store.

1. date: Formatting Date and Time The date filter is used to format dates in a readable format.

Code Example: Formatting the Current Date

<!-- Display the current date in "Month day, year" format -->
{{ 'now' | date: "%B %d, %Y" }}

2. capitalize: Capitalizing Strings This filter capitalizes the first word of a string, useful for titles and names.

Code Example: Capitalizing a Product Title

<!-- Capitalize the first word of the product title -->
{{ product.title | capitalize }}

3. money: Formatting Prices The money filter formats numbers into a currency format, based on the shop currency.

Code Example: Displaying Price in Money Format

<!-- Display the price of a product in money format -->
{{ product.price | money }}

4. default: Setting Default Values Use the default filter to specify a fallback in case a variable is null or empty.

Code Example: Setting Default Text

<!-- Output the product description or a default message if none exists -->
{{ product.description | default: "No description available." }}

5. url_for_type: Generating URLs for Object Types This filter generates a URL for a given object type within Shopify.

Code Example: Link to All Products of a Certain Type

<!-- Create a URL for products of a specific type -->
<a href="{{ 'leather' | url_for_type: 'product_type' }}">Shop All Leather Goods</a>
