How to Check If a Product Has Variations Programmatically in WordPress

Introduction

When building custom functionality in WooCommerce, you often need to handle products with variations—like different sizes, colors, or styles. As a developer, you may want to programmatically check if a product has variations to customize the way you display or interact with these products.

In this post, we’ll walk through a simple and effective code snippet that checks if a product has variations in WooCommerce. Let’s get started!

Code Snippet: Checking for Product Variations

Here’s the code snippet that does the job:

$product_id = 333; // Replace it with your product ID
$product = wc_get_product( $product_id );

if( $product->is_type( 'variable' ) ) 
{

    if( $product->get_available_variations() ) 
    {
        echo 'This product has variations.';
    } else 
    {
        echo 'This product does not have variations.';
    }
} 
else 
{
    echo 'This product is not a variable product.';
}

Explanation:

• wc_get_product($product_id): This function retrieves the product object based on the product ID.
• is_type('variable'): This checks if the product is a variable product, which means it can have variations.
• get_available_variations(): This method retrieves all available variations for the product. If the method returns a non-empty array, the product has variations.
• Based on the outcome, the code will print whether the product has variations or not, or whether it’s a non-variable product.

Example Use Case:

• Custom Product Display: If a product has variations, you might want to show different content on the product page. For example, you could highlight available variations prominently or display a different layout for variable products.
• Conditional Logic: Use this snippet to apply conditional logic. For instance, you might only display a “Select Options” button for products with variations and a “Buy Now” button for simple products.
