Liquid Loops
Loop Structures
Liquid loops use for to iterate Shopify collections or arrays.
Introduction to Liquid Loops
Liquid is a template language used in Shopify themes to display dynamic content. One of the fundamental features of Liquid is its ability to loop over collections or arrays, allowing you to display multiple items dynamically. This is particularly useful for displaying lists of products, blog posts, or any other repeated elements on a Shopify store.
Basic Syntax of Liquid Loops
The basic structure of a loop in Liquid involves the {% for %} and {% endfor %} tags. You iterate over a collection or array by specifying the collection and a variable name to represent each item in the collection.
Using Liquid Loops with Arrays
Liquid loops can also iterate over arrays. Arrays can be custom-made or part of Shopify's built-in collections. Here's an example of looping over a custom array:
Looping Through Shopify Collections
Shopify provides several built-in collections such as collections, products, and blogs. You can loop through these collections to display their contents. For example, to list all products in a specific collection:
Controlling Loop Behavior
Liquid provides several filters and control structures to manage loop behavior, such as limit, offset, and reversed:
- Limit: Restricts the number of iterations.
- Offset: Skips a specified number of items.
- Reversed: Iterates over items in reverse order.
Conclusion
Understanding and utilizing Liquid loops is essential for developing dynamic and flexible Shopify themes. By mastering loops, you can efficiently display and manage numerous elements within your store, enhancing both the user interface and user experience.
