Control flow tags
Control flow tags create conditions that decide whether blocks of Liquid code get executed.
if
Executes a block of code only if a certain condition is met (that is, if the result is true
).
{% if product.title == 'Awesome Shoes' %}
You are buying some awesome shoes!
{% endif %}
You are buying some awesome shoes!
unless
Like if, but executes a block of code only if a certain condition is not met (that is, if the result is false
).
{% unless product.title == 'Awesome Shoes' %}
You are not buying awesome shoes.
{% endunless %}
You are not buying awesome shoes.
else / elsif
Adds more conditions to an if
or unless
block.
{% if shipping_method.title == 'International Shipping' %}
You're shipping internationally. Your order should arrive in 2–3 weeks.
{% elsif shipping_method.title == 'Domestic Shipping' %}
Your order should arrive in 3–4 days.
{% else %}
Thank you for your order!
{% endif %}
Your order should arrive in 3–4 days.
case / when
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.
You can optionally add an else
statement at the end of the case to provide code to execute if none of the conditions are met.
{% case shipping_method.title %}
{% when 'International Shipping' %}
You're shipping internationally. Your order should arrive in 2–3 weeks.
{% when 'Domestic Shipping' %}
Your order should arrive in 3–4 days.
{% when 'Local Pick-Up' %}
Your order will be ready for pick-up tomorrow.
{% else %}
Thank you for your order!
{% endcase %}
Your order should arrive in 3–4 days.
