How to Get Variation Price in WooCommerce: A Beginner’s Guide
WooCommerce is a fantastic platform for selling online, especially when you need to offer product variations like different sizes, colors, or materials. But figuring out how to programmatically access and display the price of a specific variation can be tricky, especially for beginners. Don’t worry, this guide will break it down for you in a simple, easy-to-understand way.
Think of it this way: imagine you’re selling t-shirts. You have a base price, but the price changes based on the size (small, medium, large) or the color (red, blue, green). You need a way to show your customers the *actual* price of the *specific* t-shirt they’re interested in. That’s what we’re going to learn!
Why is Accessing Variation Prices Important?
Knowing how to retrieve variation prices is crucial for several reasons:
- Dynamic Pricing: You can display the correct price based on user selections. Imagine showing “Starting at $10” on the product page, but the price changes to $12 when someone selects a large size.
- Custom Calculations: You might need to perform calculations based on the variation price, such as applying specific discounts or calculating shipping costs.
- Improved User Experience: Showing accurate prices ensures transparency and builds trust with your customers. Nobody likes hidden fees or surprises at checkout!
- Advanced Theme Customization: You can customize your WooCommerce theme to display prices in unique ways, tailored to your brand and design.
- `wc_get_product($product_id)`: This function retrieves a WooCommerce product object. You’ll need the product ID.
- `get_available_variations()`: This method, called on a variable product object, returns an array of all available variations. Each variation is an associative array containing information like the price and attributes.
- `get_price()`: Once you have the variation product object (from looping through `get_available_variations()`), you can use this method to retrieve Learn more about How To Configure Paypal Standard Woocommerce the price.
Methods for Getting Variation Prices
There are a few ways to get the variation price in WooCommerce. We’ll focus on the most common and reliable methods, suitable for beginners.
1. Using WooCommerce Functions (PHP)
This is the most flexible and powerful method, perfect for developers and those comfortable with a little bit of code.
Example:
Let’s say you want to display the lowest variation price on a product page. Here’s how you might do it in PHP (within your theme’s `functions.php` file or a custom plugin):
<?php /**
if ( ! $product || ! $product->is_type( ‘variable’ ) ) {
return ”; // Not a variable product
}
$variations = $product->get_available_variations();
if ( empty( $variations ) ) {
return ”; // No variations available
}
$lowest_price = PHP_INT_MAX; // Initialize with a large value
foreach ( $variations as $variation ) {
$variation_price = floatval( $variation[‘display_price’] ); // Get price as a float
$lowest_price = min( $lowest_price, $variation_price ); // Find the minimum
}
if ( $lowest_price === PHP_INT_MAX ) {
return ”; // No valid price found
}
return wc_price( $lowest_price ); // Format with currency symbol
}
// Example usage (replace 123 with your product ID):
$product_id = 123;
$lowest_price = get_lowest_variation_price( $product_id );
if ( ! empty( $lowest_price ) ) {
echo ‘Starting at: ‘ . $lowest_price;
} else {
echo ‘Price not available’;
}
?>
Reasoning:
- We first check if the product is a variable product using `$product->is_type( ‘variable’ )`.
- We get all available variations using `$product->get_available_variations()`.
- We loop through each variation and extract the price.
- We use `min()` to find the lowest price among all variations.
- Finally, we use `wc_price()` to format the price with the correct currency symbol.
2. Using JavaScript (Frontend)
This method is useful if you need to update the price dynamically on the front end as the user selects different variations. WooCommerce provides JavaScript events that you can listen for.
- `woocommerce_variation_has_changed`: This event is triggered when a variation is selected. You can listen for this event and then use JavaScript to access the variation’s price.
- `woocommerce_variation_select_change`: This event is triggered when the variation select dropdown is changed.
Example:
jQuery( function( $ ) {
$( ‘.variations_form’ ).on( ‘woocommerce_variation_has_changed’, function() {
var variation_id = $( this ).find( ‘input[name=”variation_id”]’ ).val();
if ( variation_id ) {
// Make an AJAX request to get the variation data. This is a simplified example; you might need to adjust it.
$.ajax({
type: ‘POST’,
url: wc_add_to_cart_params.ajax_url, // Get AJAX URL from WooCommerce
data: {
action: ‘get_variation_price’, // Define an action in your PHP code
variation_id: variation_id
},
success: function( response ) {
// Update the price on the page
$( ‘.variation-price’ ).html( response );
}
});
} else {
// No variation selected, clear the price
$( ‘.variation-price’ ).html( ” );
}
});
});
PHP (for the AJAX request
<?php add_action( 'wp_ajax_get_variation_price', 'get_variation_price_callback' ); add_action( 'wp_ajax_nopriv_get_variation_price', 'get_variation_price_callback' ); // For non-logged-in users
function get_variation_price_callback() {
$variation_id = intval( $_POST[‘variation_id’] );
$variation = wc_get_product( $variation_id );
if ( $variation ) {
$price = $variation->get_price_html(); // Get formatted price (with currency)
echo $price;

echo ‘Price not available’;
}
wp_die(); // Required to terminate AJAX request properly
}
?>
HTML (where you want to display the price):
Reasoning:
- The JavaScript listens Read more about How To Access Woocommerce Root for the `woocommerce_variation_has_changed` event.
- When a variation is selected, it retrieves the `variation_id`.
- It makes an AJAX request to a PHP function (`get_variation_price_callback`).
- The PHP function retrieves the variation object using `wc_get_product()` and gets the formatted price using `$variation->get_price_html()`.
- The JavaScript then updates the `variation-price` div with the returned price.
- Important: This example uses AJAX because you can’t directly access the price on the client-side without retrieving it from the server.
Key Considerations
- Error Handling: Always include error handling in your code. Check if the product is a variable product, if variations exist, and if the price is valid. Display appropriate messages to the user if something goes wrong.
- Caching: If you’re retrieving variation prices frequently, consider using caching to improve performance. WooCommerce has built-in caching mechanisms that you can leverage.
- Security: When using AJAX, always sanitize and validate the data you receive from the client-side to prevent security vulnerabilities. Use `intval()` as shown in the PHP example.
- Theme Compatibility: Make sure your code is compatible with your WooCommerce theme. Some themes might override the default WooCommerce templates or have their own JavaScript code that could interfere with your code.
Conclusion
Getting the variation price in WooCommerce is essential for providing a seamless and accurate shopping experience. By understanding the different methods and key considerations outlined in this guide, you’ll be well-equipped to display dynamic prices, perform custom calculations, and enhance your WooCommerce store’s functionality. Remember to choose the method that best suits your needs and skill level. Good luck!
