How to Update Product Price Programmatically in WooCommerce

Do you want to learn how to update the product price programmatically in WooCommerce? In this guide, we’ll show you how to change prices in WooCommerce without using plugins or installing extra tools.

If you use them smartly, discounts can help you improve your conversion rates and increase your sales. There are several ways to implement discounts on your e-commerce store. For example, you can apply WooCommerce coupons programmatically.

However, you can also update the product price without using coupons. For example, you could give an exclusive discount to users who subscribe to your newsletter or who have spent more than $100 in your store.

In this guide, you’ll learn to change the price when customers add a product to the cart without using coupons and by accessing the WooCommerce cart object directly. We’ll look at some examples and apply some logic when updating the price.

The goal is that you understand the logic so you can customize the scripts and apply them to your store.

When Should You Update Product Price Programmatically?

There are several situations where updating product prices manually just isn’t efficient. That’s when you should consider using code to change product pricing. Here are the most common scenarios where it makes sense to update WooCommerce product prices programmatically:

• Bulk Price Updates: Manually changing prices can be time-consuming when managing hundreds or thousands of products. A programmatic approach lets you update prices quickly and accurately in bulk.
• Dynamic Pricing Rules: When your pricing depends on real-time data—like currency rates, competitor prices, or stock levels—you can use custom scripts to change WooCommerce product prices automatically.
• Sales and Promotions: Want to run flash sales or apply discounts automatically on certain days? You can programmatically schedule a WooCommerce product price update using cron jobs or hooks.
• External Data Integration: If your store pulls pricing from an external system or API, you’ll need a reliable way to update product prices automatically in WooCommerce.
• Multi-Store or Multi-Vendor Setup: If prices need to be synced across multiple stores or vendor portals, the code ensures consistency and reduces manual effort.

By automating these processes, you can eliminate repetitive tasks and reduce the risk of human error, making your WooCommerce store more efficient and scalable.

How to Update the Product Price Programmatically in WooCommerce

In this section, you’ll learn how to update the product price programmatically in WooCommerce. We’ll look at different examples to give you some ideas of what you can do in your store.

1. Update product price when a checkbox is selected
   1. Add the checkbox input field to the products page
   2. Update the price when a user adds a product to the cart
   3. Recalculate the total price of the cart
2. Edit the product price based on user roles
3. Update the product price based on the product taxonomy

Remember that we’ll use several WooCommerce hooks, so it’s a good idea to check out this guide if you’re unfamiliar with them.

Before we start…

Before we start, as we’ll modify some core files, we recommend you install a child theme on your site. If you don’t have a child theme and you don’t know how to install it, check out our guide to creating a child theme or our list of the best child theme plugins.

NOTE: To apply these scripts, copy and paste them into the functions.php child theme file. However, remember that they’re intended solely for didactic purposes, so customize them before taking them to production.

1) Update Product Price When a Checkbox is Selected

In the following sample script, we’ll add a checkbox input in the cart form on the product page. This way, we can apply custom logic and dynamically update the price of any product that customers add to the cart only when the checkbox is selected.

1.1 Add the Checkbox Input Field to the Products Page

Before we update the WooCommerce product price programmatically, let’s add the checkbox to the products page. To do that, copy and paste the following script:

add_action('woocommerce_after_add_to_cart_button', 'add_check_box_to_product_page', 30 );
function add_check_box_to_product_page(){ ?>     
       <div style="margin-top:20px">           
<label for="extra_pack"> <?php _e( 'Extra packaging', 'quadlayers' ); ?>
<input type="checkbox" name="extra_pack" value="extra_pack"> 
</label>
                    
</div>
     <?php
}

The woocommerce_after_add_to_cart_button The hook allows us to print the checkbox right after the button, as shown in the image above.

1.2 Update the price when the user adds a product to the cart

Another interesting option is to update prices when customers add products to their carts dynamically. So, in this case, to update the price programmatically in WooCommerce, paste this script right after the previous one.

add_filter( 'woocommerce_add_cart_item_data', 'add_cart_item_data', 10, 3 );
 
function add_cart_item_data( $cart_item_data, $product_id, $variation_id ) {
     // get product id & price
    $product = wc_get_product( $product_id );
    $price = $product->get_price();
    // extra pack checkbox
    if( ! empty( $_POST['extra_pack'] ) ) {
       
        $cart_item_data['new_price'] = $price + 15;
    }
return $cart_item_data;
}

woocommerce_add_cart_item_data is the WooCommerce hook that will allow us to edit the price of the current product. Additionally, the if() conditional checks whether the checkbox is selected, and if it is, updates the price in the following line. Now, let’s break down the code to understand better what each part does.

• extra_pack is the name of the checkbox we’ve created in the previous step
• $price is the current product price. We can modify it as we want, with some conditions
• $cart_item_data['new_price'] = $price + 15; is how we increase the price by $15 is when the if() condition is true, which is when the user selects the extra packaging checkbox. By adjusting the code, you can increase or decrease the price by any amount you want.

1.3 Recalculate the Total Price of the Cart

Since we can call the woocommerce_add_cart_item_data when loading the cart several times, we need to recalculate the totals and subtotals of the cart to avoid undesired results such as prices being updated multiple times or every time a user adds a product. To update the product, paste the following code after the previous two ones:

add_action( 'woocommerce_before_calculate_totals', 'before_calculate_totals', 10, 1 );
 
function before_calculate_totals( $cart_obj ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) ) {
return;
}
// Iterate through each cart item
foreach( $cart_obj->get_cart() as $key=>$value ) {
if( isset( $value['new_price'] ) ) {
$price = $value['new_price'];
$value['data']->set_price( ( $price ) );
}
}
}

This function ensures we update the price only when a product matches our conditional logic (i.e., when the user selects the extra packaging checkbox). This way, we prevent all potential errors when calculating the cart’s total price.

Product price increases by $15

If everything goes well and the cart meets the conditions we set, our function will add an extra $15 charge to the original price when the user selects the checkbox on the product page before clicking the Add to cart button.

To reduce cart abandonment and improve the buying experience, always display the new price before customers add products to their carts. Otherwise, they’ll only see the final price on the checkout page.

2. Edit the Product Price Based on User Roles

Similarly, we can programmatically update the WooCommerce product price based on user roles. For example, you could give subscribed or registered users an exclusive discount. To do that, copy and paste the following script:

function add_cart_item_data( $cart_item_data, $product_id, $variation_id ) {
    // get product id & price
   $product = wc_get_product( $product_id );
   $price = $product->get_price();
   if(// Is logged in && is customer role
       is_user_logged_in()==true&& wc_current_user_has_role( 'customer' )){
       
        $cart_item_data['new_price'] = $price * 0.8;
   }
return $cart_item_data;
}
add_filter( 'woocommerce_add_cart_item_data', 'add_cart_item_data', 10, 3 );

As you can see, the only difference between this script and the previous one in point 1.2 is the if() logic operator. Here, we check whether the user is logged in and has a customer role, which we assign to registered users who have purchased from our store before.

When a shopper meets that condition, we multiply the product price by 0.8, giving them a 20% discount. Of course, you can edit and change other users’ roles, such as Subscriber, Editor, or any other roles you have registered on your website.

Note that to work correctly, you must use the 'before_calculate_totals' function and its hook to recalculate the cart totals. So, recalculate the cart script’s total price from step 1.3.

3. Update Product Price Based on Product Taxonomy

Finally, in WooCommerce, we can also dynamically update the product price programmatically based on product taxonomies. To do that, let’s look at the following script.

add_filter( 'woocommerce_add_cart_item_data', 'add_cart_item_data', 10, 3 );
 
function add_cart_item_data( $cart_item_data, $product_id, $variation_id ) {
     // get product id & price
    $product = wc_get_product( $product_id );
    $price = $product->get_price();
    $terms = get_the_terms( $product_id, 'product_cat' );
    // Category match ! apply discount
    if($terms[0]->name=='Posters'){                    
        $cart_item_data['new_price'] = $price + 20;
     }   
return $cart_item_data;
 
}

In this example, we are getting the category of the product that has been added to the cart using the get_the_terms() WordPress’s built-in function. In the following line, we apply our condition to retrieve the category of the product using $terms[0]->name. This way, if the product belongs to the category Posters, we increase the price by $20.

This is a sample script that you can use as a base and edit to change the taxonomy and the amount you want to add or deduct from the price.

Finally, remember to use the 'before_calculate_totals' function and its corresponding hook as we did in step 1.3.

---

As you can see, the know-how to use conditional statements and WordPress/WooCommerce functions provides a highly flexible way to update product prices programmatically. These are just a few examples to give you ideas of what’s possible.

However, there’s a lot more you can do to unleash your creativity and find new ways to lower your product prices. For example, you can apply discounts based on specific product IDs, the URL users came from, users’ location or ID, and so on. The possibilities are endless —play around with the script and find the best solutions for your store.

FINAL NOTES

• These sample scripts in points 1, 2, and 3 will not work together. You will need to refine your logic into a single one if you want to apply multiple functions at the same time.
• You may need to include additional validation functions for more complex conditional logic.
• Always apply a recalculation function, as seen in point 1.3, when working with the WooCommerce cart object.
• These are sample scripts and are intended for didactic purposes only. Please adjust them before taking them into production.

Pro Tips for Safe Price Updates

Here are some pro tips you should keep in mind:

• Always back up your site before running any code that updates product prices. This ensures you can restore your data if something goes wrong.
• Test your code in a staging environment first. Avoid making changes directly on your live WooCommerce store.
• Use product IDs carefully. Double-check that you update the correct product or variation to prevent accidental price changes.
• Include validation and error handling in your code to catch potential issues before they affect your live site.
• Avoid bulk updates during peak traffic hours to minimize potential disruptions for customers browsing your store.
• Log your changes. Maintain a log file or an admin notification system to track price modifications.
• Keep your WooCommerce version updated. Compatibility with functions like woocommerce_update_product_price_programmatically or woocommerce_change_product_price_programmatically often depends on having the latest version.
• Use WooCommerce hooks and functions properly to ensure updates align with WooCommerce’s best practices.
• Avoid hardcoding values. If you update prices regularly, consider using variables or dynamic inputs based on specific criteria, such as stock levels or seasonal demand.

Common Mistakes to Avoid

• Directly editing core WooCommerce files instead of using hooks or custom functions. This can break your site during updates.
• Failing to sanitize or validate input values can lead to unexpected behavior or vulnerabilities.
• Updating prices without checking product types can cause issues when working with variable or grouped products.
• Running update scripts on every page load can slow down your site and overload your server.
• Ignoring WooCommerce caching mechanisms, which can prevent new prices from showing immediately on the frontend.
• Not using wp_update_post() or wc_delete_product_transients() When necessary, this might result in price changes not reflecting properly.
• Applying the same price to all variations blindly, especially when each variation needs a unique price.
• Forgetting to test edge cases like out-of-stock products, draft products, or those with set sale prices.
