Liquid filters
Filters are simple methods that modify the output of numbers, strings, variables and objects. They are placed within an output tag
{{ }} and are denoted by a pipe character |.Input
<!-- item.title = "Invisible Watch" -->
{{ item.title | upcase }}
Output
INVISIBLE WATCH
In the example above,
item is the object, title is its attribute, and upcase is the filter being applied.Some filters require a parameter to be passed.
Input
{{ item.title | remove: "Invisible" }}
Output
Watch
Multiple filters can be used on one output. They are applied from left to right.
Input
<!-- item.title = "Invisible Watch" -->
{{ item.title | upcase | remove: "INVISIBLE" }}
Output
WATCH
Array filters change the output of arrays. Array is a synonym to list. For example,
order.line_items is an array of line items or order.transactions is an array of transactions.Joins the elements of an array with the character passed as the parameter. The result is a single string.
Input
{{ product.tags | join: ', ' }}
Output
tag1, tag2, tag3
Returns the first element of an array.
Input
<!-- product.tags = "sale", "mens", "womens", "awesome" -->
{{ product.tags | first }}
Output
sale
You can use
first with dot notation when you need to use the filter inside a tag.{% if product.tags.first == "sale" %}
This product is on sale!
{% endif %}
Returns the last element of an array.
Input
<!-- product.tags = "sale", "mens", "womens", "awesome" -->
{{ product.tags | last }}
Output
awesome
You can use
last with dot notation when you need to use the filter inside a tag.{% if product.tags.last == "sale"%}
This product is on sale!
{% endif %}
Using
last on a string returns the last character in the string.Input
<!-- product.title = "Awesome Shoes" -->
{{ product.title | last }}
Output
s
Concatenates (combines) an array with another array. The resulting array contains all the elements of the original arrays.
concat will not remove duplicate entries from the concatenated array unless you also use the uniq filter.Input
{% assign fruits = "apples, oranges, peaches, tomatoes" | split: ", " %}
{% assign vegetables = "broccoli, carrots, lettuce, tomatoes" | split: ", " %}
{% assign plants = fruits | concat: vegetables %}
{{ plants | join: ", " }}
Output
apples, oranges, peaches, tomatoes, broccoli, carrots, lettuce, tomatoes
You can string together multiple
concat filters to combine more than two arrays:Input
{% assign fruits = "apples, oranges, peaches" | split: ", " %}
{% assign vegetables = "broccoli, carrots, lettuce" | split: ", " %}
{% assign animals = "dogs, cats, birds" | split: ", " %}
{% assign things = fruits | concat: vegetables | concat: animals %}
{{ things | join: ", " }}
Output
apples, oranges, peaches, broccoli, carrots, lettuce, dogs, cats, birds
Returns the item at the specified index location in an array. Note that array numbering starts from zero, so the first item in an array is referenced with
[0].Input
<!-- product.tags = "sale", "mens", "womens", "awesome" -->
{{ product.tags[2] }}
Output
womens
Accepts an array element's attribute as a parameter and creates an array out of each array element's value.
Input
<!-- collection.title = "Spring", "Summer", "Fall", "Winter" -->
{% assign collection_titles = collections | map: 'title' %}
{{ collection_titles }}
Output
SpringSummerFallWinter

Transforms an object by running each of the object's property value by a given filter. First parameter of
map_values is the filter name. The filter receives the object values one by one as its first parameter. All remaining parameters provided to map_values are passed down to the given filter. Input
<!--
dimensions = { depth: 3, height: 5, width: 7 }
-->
{% assign doubled = dimensions | map_values: "times", 2 %}
{{ doubled.depth }}
{{ doubled.height }}

You can use
size with dot notation when you need to use the filter inside a tag.{% if collections.frontpage.products.size > 10 %}
There are more than 10 products in this collection!
{% endif %}
Sorts the elements of an array by a given attribute of an element in the array.
{% assign products = collection.products | sort: 'price' %}
{% for product in products %}
<h4>{{ product.title }}</h4>

The order of the sorted array is case-sensitive.
Input
<!-- products = "a", "b", "A", "B" -->
{% assign products = collection.products | sort: 'title' %}
{% for product in products %}
{{ product.title }}
{% endfor %}
Output
A B a b
Creates an array including only the objects with a given property value, or any truthy value by default.

{% for product in kitchen_products %}
- {{ product.title }}
{% endfor %}
Output
All products:
- Vacuum
- Spatula
- Television
- Garlic press
Kitchen products:

You can use a property name with
where that has no target value when that property is a boolean or truthy. For example, the available property of products.Example
{% assign available_products = collection.products | where: "available" %}
Available products:
{% for product in available_products %}
- {{ product.title }}
{% endfor %}

Math filters allow you to apply mathematical tasks.
Math filters can be linked and, as with any other filters, are applied in order of left to right. In the example below,
minus is applied first, then times, and finally divided_by.CopyYou save {{ product.compare_at_price | minus: product.price | times: 100.0 | divided_by: product.compare_at_price }}%

Input
{{ "<p>test</p>" | escape }}
Output
<p>test</p>
Extracts a first number from a string. It works for integers (123), decimal numbers (123.45), and negative numbers (-123). The extracted number is still a text so it doesn't strip leading zeros (0123).
Input
{%- capture note -%}
Foo 123 Bar 456
{%- endcapture -%}
{{ note | extract_number }}
Output
123
Extracts all numbers from a string. It works for integers (123), decimal numbers (123.45), and negative numbers (-123). The extracted numbers are still a text to preserve leading zeros (0123).
The result is an array.
Input
{%- capture note -%}
Foo 012
Bar 3.4
Baz -56
{%- endcapture -%}
{{ note | extract_numbers | join: " " }}
Output
012 3.4 -56
Calculates an MD5 hash from a string.
An example use case for this filter is to calculate a checksum of a request payload, and include it in a request header. Such a checksum is required by some APIs, for example, the Richard Photo Lab API.

The
slice filter returns a substring, starting at the specified index. An optional second parameter can be passed to specify the length of the substring. If no second parameter is given, a substring of one character will be returned.Input

Truncates a string down to the number of characters passed as the first parameter. An ellipsis (...) is appended to the truncated string and is included in the character count.
Input
{{ "The cat came back the very next day" | truncate: 13 }}
Output
The cat ca...
truncate takes an optional second parameter that specifies the sequence of characters to be appended to the truncated string. By default this is an ellipsis (...), but you can specify a different sequence.The length of the second parameter counts against the number of characters specified by the first parameter. For example, if you want to truncate a string to exactly 10 characters, and use a 3-character ellipsis, use 13 for the first parameter of
truncate, since the ellipsis counts as 3 characters.Input
{{ "ABCDEFGHIJKLMNOPQRSTUVWXYZ" | truncate: 18, ", and so on" }}
Output
ABCDEFG, and so on
You can truncate to the exact number of characters specified by the first parameter and show no trailing characters by passing a blank string as the second parameter:
Input
{{ "I'm a little teapot, short and stout." | truncate: 15, "" }}
Output
I'm a little te
Truncates a string down to the number of words passed as the first parameter. An ellipsis (...) is appended to the truncated string.
Input
{{ "The cat came back the very next day" | truncatewords: 4 }}
Output
The cat came back...
truncatewords takes an optional second parameter that specifies the sequence of characters to be appended to the truncated string. By default this is an ellipsis (...), but you can specify a different sequence.Input
{{ "The cat came back the very next day" | truncatewords: 4, "--" }}
Output
The cat came back--
You can avoid showing trailing characters by passing a blank string as the second parameter:
Input
{{ "The cat came back the very next day" | truncatewords: 4, "" }}
Output
The cat came back
