Control Flow

Liquid provides multiple control flow statements.

if


{% if customer.name == 'kevin' %}
  Hey Kevin!
{% elsif customer.name == 'anonymous' %}
  Hey Anonymous!
{% else %}
  Hi Stranger!
{% endif %}

unless

The opposite of if – executes a block of code only if a certain condition is not met.


{% unless product.title == 'Awesome Shoes' %}
These shoes are not awesome.
{% endunless %}

case

Creates a switch statement to compare a variable with different values. case initializes the switch statement, and when compares its values.


{% assign handle = 'cake' %}
{% case handle %}
  {% when 'cake' %}
    This is a cake
  {% when 'cookie' %}
    This is a cookie
  {% else %}
    This is not a cake nor a cookie
{% endcase %}

for

Repeatedly executes a block of code. break = Causes the loop to stop iterating when it encounters the break tag. continue = Causes the loop to skip the current iteration when it encounters the continue tag.


{% for i in (1..10) %}
  {% if i == 4 %}
    {% break %}
  {% elsif i == 6 %}
    {% continue %}
  {% else %}
    {{ i }}
  {% endif %}
{% endfor %}

range


{% for i in (3..5) %}
  {{ i }}
{% endfor %}

{% assign num = 4 %}
{% for i in (1..num) %}
  {{ i }}
{% endfor %}
