Liquid String Filters

Introduction to Liquid String Filters

Liquid string filters are powerful tools in Shopify that allow developers to manipulate and format text content dynamically. These filters can be used to append text, split strings, capitalize words, and much more. In this guide, we'll explore some of the most commonly used string filters to help you make the most of your Shopify templates.

Using the Append Filter

The append filter is used to add additional text to a string. This is particularly useful when you want to concatenate strings in your Shopify templates.

Syntax: {{ input | append: 'string_to_append' }}

Let's see an example of how this works in practice:

The above code will output: Shopify Store. As you can see, the text ' Store' is added to the original string 'Shopify'.

Splitting Strings with the Split Filter

The split filter is used to divide a string into an array based on a specified delimiter. This can be very useful when you need to process or manipulate segments of a string individually.

Syntax: {{ input | split: 'delimiter' }}

Here's an example:

This example will output:

• apple
• orange
• banana

The string is split into an array using ', ' as the delimiter, and each fruit is then output individually in a loop.

Additional String Filters

Besides append and split, Liquid offers several other string filters to enrich text manipulation:

• upcase: Converts all characters in a string to uppercase. {{ 'shopify' | upcase }} will output SHOPIFY.
• downcase: Converts all characters in a string to lowercase. {{ 'SHOPIFY' | downcase }} will output shopify.
• capitalize: Capitalizes the first letter of a string. {{ 'shopify' | capitalize }} will output Shopify.
• replace: Replaces every occurrence of a substring with another string. {{ 'apples and oranges' | replace: 'apples', 'bananas' }} will output bananas and oranges.

These filters provide you with robust options to format and manipulate text in Shopify's Liquid templates.

Practical Uses of String Filters

String filters can be incredibly useful in Shopify themes for customizing the display of product titles, descriptions, and more. By leveraging these filters, you can create dynamic and responsive templates that enhance the user experience.

For example, you might use the append filter to add a trademark symbol to product names or the capitalize filter to ensure consistent title formatting across your store.

Conclusion

Liquid string filters are essential tools for any Shopify developer looking to manipulate and format text effectively. By understanding and using filters like append and split, you can enhance the functionality and presentation of your Shopify store.
