Shopify liquid conditional tag cheatsheet

Here’s a Shopify Liquid Conditional Tag Cheatsheet with examples ranging from simple to more complex. It will help you understand how to use conditional logic in your Shopify theme templates: Basic Conditional Tags

1. Simple if Condition

{% if condition %}
  <!-- Code to execute if the condition is true -->
{% endif %}

Example:

{% if product.available %}
  <p>This product is available!</p>
{% endif %}

2. If-Else Condition

{% if condition %}
  <!-- Code if condition is true -->
{% else %}
  <!-- Code if condition is false -->
{% endif %}

Example:

{% if product.compare_at_price > product.price %}
  <p>On Sale!</p>
{% else %}
  <p>Regular Price</p>
{% endif %}

3. If-Elsif-Else Condition

{% if condition1 %}
  <!-- Code if condition1 is true -->
{% elsif condition2 %}
  <!-- Code if condition2 is true -->
{% else %}
  <!-- Code if neither condition is true -->
{% endif %}

Example:

{% if product.available %}
  <p>In Stock</p>
{% elsif product.incoming %}
  <p>Pre-order</p>
{% else %}
  <p>Out of Stock</p>
{% endif %}

Conditional with Operators

4. Equality

{% if product.type == "Shirt" %}
  <p>This is a shirt</p>
{% endif %}

5. Comparison Operators

Greater than: > Less than: < Greater than or equal to: >= Less than or equal to: <= Not equal to: !=

Example:

{% if product.price < 100 %}
  <p>This item is under $100</p>
{% endif %}

6. Logical Operators

And: and Or: or

Example:

{% if product.available and product.price < 50 %}
  <p>Special offer on this available item under $50!</p>
{% endif %}

Complex Conditional Logic

7. Combining Multiple Conditions

{% if product.available and product.tags contains "featured" %}
  <p>This product is available and featured!</p>
{% elsif product.tags contains "new-arrival" %}
  <p>This is a new arrival!</p>
{% else %}
  <p>Check other products</p>
{% endif %}

8. Using Unless (Inverse of If)

{% unless product.available %}
  <p>This product is sold out.</p>
{% endunless %}

Explanation:

unless is the opposite of if. It will execute the code block only if the condition is false.

9. Checking Arrays or Strings

String contains: contains

Example:

{% if customer.email contains "gmail.com" %}
  <p>Looks like you're using a Gmail account!</p>
{% endif %}

Array contains:

{% if collection.tags contains "summer" %}
  <p>This is a summer collection</p>
{% endif %}

Advanced Conditional Logic

10. For Loop with Conditionals

{% for product in collections.all.products %}
{% if product.available %}
<p>{{ product.title }} is available</p>
{% endif %}
{% endfor %}

11. Checking the Length of Arrays

{% if collections.frontpage.products.size > 0 %}
  <p>We have {{ collections.frontpage.products.size }} products available.</p>
{% else %}
  <p>No products available.</p>
{% endif %}

12. Check for Nil or Empty Values

{% if product.description != blank %}
  <p>{{ product.description }}</p>
{% else %}
  <p>No description available</p>
{% endif %}

13. Combining Multiple Conditions with Nested Conditionals

{% if product.available %}
  <p>{{ product.title }} is in stock!</p>
  {% if product.price < 20 %}
    <p>This item is less than $20, great deal!</p>
  {% else %}
    <p>It’s over $20, but still worth it!</p>
  {% endif %}
{% else %}
  <p>Sorry, {{ product.title }} is out of stock.</p>
{% endif %}

14. Using Case-When (Switch Statement)

{% case product.type %}
{% when "Shirt" %}
<p>This is a shirt.</p>
{% when "Pants" %}
<p>These are pants.</p>
{% else %}
<p>This is another type of product.</p>
{% endcase %}

Liquid Filters in Conditionals

15. Using Filters within Conditionals

{% if product.title | downcase == "special product" %}
  <p>This is the special product!</p>
{% endif %}

16. Using Contains with Strings or Arrays

{% if product.tags contains "summer" %}
  <p>This product is part of the summer collection!</p>
{% endif %}
