Control Flow Tags

These tags are used to control the flow of logic in Liquid templates. They allow you to create conditions, loops, and manage how content is rendered based on different scenarios. Use these tags to add logic and branching to your templates.

case

Creates a switch statement to execute a particular block of code when a variable has a specified value. case initializes the switch statement, and when statements define the various conditions.

An optional else statement at the end of the case provides code to execute if none of the conditions are met.

Input

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

Output

This is a cake

if

Executes a block of code only if a certain condition is true.

Input

{% if product.title == "Awesome Shoes" %} These shoes are awesome! {% endif %}

Output

These shoes are awesome!

You can add more conditions within if block with elsif or else

Input

{% if false %} This won't render... {% elsif true %} ...but this will {% endif %}

{% unless product.title == "Awesome Shoes" %} These shoes are not awesome! {% endif %}
