In Shopify themes, Liquid is the templating language used to create dynamic content on the store’s pages. It allows you to render content dynamically, loop through data, display variables, and implement logic based on the store’s settings or user interactions. Liquid objects are the most common way to access and display data in Shopify themes. Here’s a breakdown of the main types of Liquid objects you’ll encounter in Shopify themes:

1. Global Objects

These are objects that provide general information about the store, page, and session. They are globally accessible in any template or section.

• shop: Contains information about the store itself, such as its name, domain, currency, and more.

  • Example: {{ shop.name }}

• cart: Provides access to the current shopping cart’s details.

  • Example: {{ cart.item_count }} items in your cart

• customer: Contains information about the logged-in customer, such as their name, email, and addresses.

  • Example: {{ customer.first_name }}

• current_page: The current page being viewed.

  • Example: {{ current_page }}

• content_for_header: Includes all dynamic content for the header (scripts, meta tags, etc.).

  • Example: {{ content_for_header }}

• checkout: Available on checkout-related templates and gives access to checkout-specific data.

  • Example: {{ checkout.total_price }}

2. Collection Objects

These objects represent Shopify collections (groups of products).

• collection: Represents the current collection being viewed.

  • Example: {{ collection.title }}

• collections: A global object that holds all collections of the store.

  • Example: {{ collections.all.products | size }} products in total

3. Product Objects

These objects deal with products in the store.

• product: Represents a single product.

  • Example: {{ product.title }}

• products: A global object containing all products in the store (useful for searching or listing products).

  • Example: {{ products.size }}

4. Page Objects

Pages are static content like “About Us” or “Contact Us.”

• page: Represents a single page.

  • Example: {{ page.title }}

• pages: Contains all pages in the store.

  • Example: {{ pages.contact_us.body }}

5. Blog and Article Objects

Shopify allows you to add a blog to your store.

• blog: Represents a blog on the site.

  • Example: {{ blog.title }}

• article: Represents a single article from a blog.

  • Example: {{ article.title }}

6. Order Objects

Order objects are used when displaying order confirmation or account history pages.

• order: Represents a customer’s order.

  • Example: {{ order.total_price }}

• orders: A list of orders made by the current customer.

  • Example: {{ orders.size }}

7. Image and Media Objects

These objects are used to work with images and media files in Shopify.

• image: Represents an image in Shopify. You can access its various properties like URL, dimensions, and alt text.

  • Example: {{ image.src }}

• media: Represents any media, including images and videos.

  • Example: {{ media.preview_image | img_url: 'large' }}

8. Storefront and User Session Objects

These objects are used to capture session data or other temporary info.

• locale: The current locale or language of the store.

  • Example: {{ locale }}

• country: The current country of the store.

  • Example: {{ country.name }}

9. Custom Objects

Shopify allows you to define custom objects in themes for flexibility. For example, you might define custom data through Metafields or custom sections in a theme.

• Metafields: Used to store custom data for products, customers, or orders.

  • Example: {{ product.metafields.custom_field }}

10. Special Objects for Themes

• theme: Contains information about the current theme.

  • Example: {{ theme.name }}

• settings: Contains the settings and configurations defined in the theme editor.

  • Example: {{ settings.logo | img_url: 'medium' }}

Example Usage in a Theme Template

If you’re customizing a Shopify theme and want to display product information in a loop, you might use Liquid objects like this:

In this example:

• collections.frontpage.products accesses the products in the “frontpage” collection.

• {{ product.title }} outputs the product title.

• {{ product.price | money }} formats the product price using the store’s currency.

Conclusion

Liquid objects in Shopify themes provide the necessary tools to display and manipulate store data, create dynamic content, and customize the storefront. They’re essential for building a fully functional and personalized e-commerce experience.

Sure! In Shopify, metafields are custom fields that allow you to store additional information about various resources (such as products, collections, customers, orders, etc.) that isn’t included in Shopify’s standard data fields. This means you can add extra data tailored to your business needs.

Here’s how they work and what you can do with them:

Key Features of Shopify Metafields:

1. Custom Data: Metafields can store extra details like dimensions, colors, ingredients, custom descriptions, or anything else that’s specific to your products, collections, or other Shopify resources.

2. Flexible Data Types: You can store a variety of data types in metafields, such as text, numbers, dates, URLs, files (like images or documents), references to other resources, etc.

3. Accessibility: Once set up, metafields can be accessed and displayed on the storefront, in the Shopify admin, or even used in automated workflows (like through Shopify Flow).

4. Custom Use Cases:

   • Products: Add extra product information that isn’t covered by Shopify’s default fields, like product features, materials, or size guides.

   • Orders: Store special instructions or order-related data, like gift messages or custom requests.

   • Customers: You could add data about customer preferences, loyalty points, or account numbers.

   • Collections: You could store additional metadata about a collection, such as a promotion code or theme-specific data.

Structure of a Metafield:

A metafield typically has three key parts:

• Namespace: A way to group related metafields. It helps you organize and identify them. For example, you might have a product namespace for product-specific data.

• Key: A unique identifier within the namespace. For example, weight_kg could be a key for storing product weight.

• Value: The actual data or content you’re storing. This could be a number, a string of text, a file URL, or any other type of value.

Example Use Cases:

• Product Page: Let’s say you want to add a custom “Care Instructions” section to a product. You could create a metafield with the key care_instructions and store the instructions as a text value.

• Customer Loyalty Program: You could add a metafield for each customer to store their loyalty points balance, allowing you to display a customer-specific offer.

• Special Offers: A metafield on a collection could store a special promotion code or a discount percentage that applies only to that collection.

Managing Metafields:

You can create, edit, and view metafields through:

• Shopify Admin: Under specific resource pages like products or orders.

• Shopify API: Developers can use the API to programmatically manage metafields.

• Apps: There are apps available in the Shopify App Store that provide an easier interface for managing metafields.

How to Display Metafields:

To display metafields on the storefront, you’ll need to update your theme’s code (Liquid templates). You can use the metafields object in Liquid to access and show the stored metafields on the appropriate page.

For example, to display a metafield in a product’s description:

This is useful when you want to add extra, personalized content to a product page without cluttering Shopify’s core fields.

In Summary:

Metafields offer powerful customization options in Shopify, allowing merchants to store and display tailored information beyond Shopify’s default structure. Whether for products, collections, customers, or orders, metafields enhance how data is stored and presented, improving the customer experience and streamlining internal processes.

The Liquid filter is a key feature of the Liquid templating language, used for transforming output and modifying variables in a flexible way. Filters are applied to variables in templates to change or format the output. They can be used to manipulate strings, numbers, arrays, and even control structures. Filters are typically written with a pipe (|) symbol between the variable and the filter.

How it Works:

• The basic syntax for using a filter is:

  liquid

  {{ variable | filter_name }}

• Filters can also be chained together to apply multiple transformations:

  liquid

  {{ variable | filter_name | another_filter }}

Common Types of Filters:

• String filters: For manipulating text.

  • upcase: Converts a string to uppercase.

  • downcase: Converts a string to lowercase.

  • capitalize: Capitalizes the first letter of the string.

  • truncate: Truncates a string to a specified length.

• Date filters: For formatting dates.

  • date: Formats a date according to a given format.

  • time: Outputs the time part of a date.

• Number filters: For formatting numbers.

  • plus: Adds a value to the number.

  • minus: Subtracts a value from the number.

  • round: Rounds the number to the nearest integer.

• Array filters: For manipulating arrays.

  • size: Returns the number of items in an array.

  • first: Returns the first element of the array.

  • last: Returns the last element of the array.

Example Usage:

1. String Manipulation:

Output: HELLO WORLD

2. Date Formatting:

Output: April 18, 2025

3. Number Arithmetic:

Output: 15

4. Array Handling:

Output: apple

This shows how you can modify data in a Liquid template to fit the needs of your output, whether for simple formatting, arithmetic, or complex string and array manipulation.
