Available Liquid filters

Article
08/16/2023

Liquid filters are used to modify the output of strings, numbers, variables, and objects. They're separated from the value to which they're being applied by a |.

{{ 'hal 9000' | upcase }} 

Some filters accept parameters. Filters can also be combined, and are applied in order from left to right.

{{ 2 | times: 2 | minus: 1 }} <!-- Output: 3 -->

{{ "Hello, " | append: user.firstname }} <!-- Output: Hello, Dave -->

The below section describes various filters.

Array filters

Array filters are used to work with arrays.

batch

Divides an array into multiple arrays of a given size.

Code

{% assign batches = entityview.records | batch: 2 %}

{% for batch in batches %}

<ul>

{% for item in batch %}

<li>{{ item.fullname }}</li>

{% endfor %}

</ul>

{% endfor %}

Output

<ul>

<li>John Smith</li>

<li>Dave Thomas</li>

</ul>

<ul>

<li>Jake Johnson</li>

<li>Jack Robinson</li>

</ul>

concat

Concatenates two arrays into a single new array.

Given a single item as a parameter, concat returns a new array that consists of the original array, with the given item as the last element.

Code

Group #1: {{ group1 | join: ', ' }}

Group #2: {{ group2 | join: ', ' }}

Group #1 + Group #2: {{ group1 | concat: group2 | join: ', ' }}

Output

Group #1: John, Pete, Hannah

Group #2: Joan, Bill

Group #1 + Group #2: John, Pete, Hannah, Joan, Bill

except

Code

{% assign redmond = entityview.records | except: 'address1_city', 'Redmond' %}

{% for item in redmond %}

{{ item.fullname }}

{% endfor %}

Output

Jack Robinson

first

Returns the first element of an array.

first can also be used with a special dot notation, in cases where it needs to be used inside a tag.

Code

{% assign words = This is a run of text | split:   %}

{{ words | first }}

{% if words.first == This %}

The first word is This.

{% endif %}

Output

This

The first word is This.

group_by

Group the items in an array by a given attribute.

Code

{% assign groups = entityview.records | group_by: 'address1_city' %}

{% for group in groups %}

{{ group.key }}:

{% for item in group.items %}

{{ item.fullname }}

{% endfor %}

{% endfor %}

Output

John Smith

Dave Thomas

Jake Johnson

New York:

Jack Robinson

join

Code

{% assign words = This is a run of text | split:   %}

{{ words | join: ,  }}

Output

This, is, a, run, of, text

last

Returns the last element of an array.

last can also be used with a special dot notation, in cases where it needs to be used inside a tag.

Code

{% assign words = This is a run of text | split:   -%}

{{ words | last }}

{% if words.last == text -%}

The last word is text.

{% endif -%}

Output

text

The last word is text.

order_by

Returns the elements of an array ordered by a given attribute of the elements of the array.

Optionally, you can provide desc as a second parameter to sort the elements in descending order, rather than ascending.

Code

{{ entityview.records | order_by: 'fullname' | join: ', ' }}

{{ entityview.records | order_by: 'fullname', 'desc' | join: ', ' }}

Output

Dave Thomas, Jack Robinson, Jake Johnson, John Smith

John Smith, Jake Johnson, Jack Robinson, Dave Thomas

random

Returns a single randomly selected item from the array.

Code

{{ group1 | join: ', ' }}

{{ group1 | random }}

Output

John, Pete, Hannah

Pete

select

Selects the value of a given attribute for each item in an array, and returns these values as an array.

Code

{{ entityview.records | select: 'address1_city' | join: ', ' }}

Output

Redmond, New York

shuffle

Applied to an array, returns a new array with the same items, in randomized order.

Code

{{ group1 | join: ', ' }}

{{ group1 | shuffle | join: ', ' }}

Output

John, Pete, Hannah

Hannah, John, Pete

size

Returns the number of items in an array.

size can also be used with a special dot notation, in cases where it needs to be used inside a tag.

Code

{% assign words = This is a run of text | split:   -%}

{{ words | size }}

{% if words.size == 6 -%}

The text contains 6 words.

{% endif -%}

Output

6

The text contains 6 words.

take

Takes a given number of items from the array, returning the taken items.

Code

{% assign words = This is a run of text | split:   %}

{{ words | take: 3 | join: ', ' }}

Output


This, is, a

then_by

Adds extra subsequent ordering to an array already ordered byorder_by.

Optionally, you can provide desc as a second parameter to sort the elements in descending order, rather than ascending.

Code

{{ entityview.records | order_by: 'address1_city' | then_by: 'fullname' | join: ', ' }}

{{ entityview.records | order_by: 'address1_city' | then_by: 'fullname', 'desc' | join: ', ' }}
