Product Add-Ons

Product Add-Ons allows you to add paid or free options to your products using several field types including radio buttons, checkboxes, drop-down fields, custom text inputs and more.

This extension also works with WooCommerce Subscriptions (separate purchase) to add additional pricing to the recurring subscription.

1. Download the extension from your WooCommerce dashboard.
2. Go to Plugins > Add New > Upload and select the ZIP file you just downloaded.
3. Click Install Now, and then Activate.

Product Add-Ons allows you to add options to multiple products in bulk, or to individual products in your catalog:

1. To add options to your products in bulk, you can create global add-ons. You may optionally limit these add-ons to specific product categories.
2. To add options to individual products, you can create per-product add-ons. Optionally, you can also prevent global add-ons from being applied to any individual product.

To create Global add-ons, go to Products > Add-Ons and click Create your first add-on.

Global add-ons are organized in groups. Each group has the following options:

• Name: This is a unique name to identify each global add-ons group and will not be visible to customers.
• Product Categories: By default, Global add-ons are inherited by every product in your store. However, you can use this option to limit individual add-on groups to specific product categories.
• Display Order: This number determines the position of the add-ons group relative to other groups in product pages. Groups with a lower Display Order are displayed higher in the product page. Add-ons created for individual products are displayed at order 10.

To add a new add-on field in a group, pick an add-on type from the Add field dropdown.

To create add-ons for individual products:

• Find and edit a product in your store.
• Go to the Product data > Add-ons tab.
• Select an add-on type from the Add field dropdown.

Alternatively, you can import some add-ons from another product.

To prevent any individual product from inheriting global add-ons, you may uncheck the Use Global Add-Ons? option.

This can be due to the length of the field name. Try to reduce the field name length or contact your hosting company to increase the value of post.max_name_length.

No, Product Add-Ons are made up of complex serialized meta data that would be difficult to do in a product CSV row as plain text. CSV Import can only import meta that is unserialized unless otherwise stated. However Product Add-Ons itself allows you to import and export settings.

No. An add-on is treated as an option, not a separate product.

No. Add-ons that are added to Variable Products are inherited by all variations. It is not possible to define different add-ons per variation.

No, there isn’t currently a datepicker add-on type.

Yes, uploads are stored in randomized folders under wp-content/uploads/ to make them hard to find. However, some hosts enable directory listing, which allows people to browse your file/folder structure. To disable this, add the following to your main .htaccess file:

Options -Indexes

Once the order has been placed, add-on data will be shown as meta. There isn’t a separate line-item for the add-on itself.

By default, a “Sold Individually” product can be added multiple times to the cart, if a different set of add-ons is selected. To ensure that “Sold Individually” products can be added only a single time to the cart, regardless of the selected add-ons, use the following snippet:

Both “Grand total” and “Options total” can be targeted via CSS, granted it is a bit tricky. Here is how using the nth-child selector:

How can I set default input values?

You can use a custom script to set default values, by inserting this code into a JavaScript file. Alternatively, you can use the free Custom CSS JS to add the code snippet.

Note that this code example only sets the value for the Custom price input field to 0 , so make sure to personalize it to your needs.

Both .mo and .po language files for Product Add-Ons should be placed in this path: /wp-content/languages/plugins/. Learn more on translating extensions here.

If you are using our Storefront theme, the add-ons will appear between the short description and the Add to Cart button.

However, on many other themes, the Add Ons are displayed beneath the Add to Cart button, which can be confusing for the customer.

To change the position, you can overwrite the template structure via a theme. Note that in the case of Product Add-Ons you need to place those template override files into a folder named addons within woocommerce-product-addons in your WordPress theme (instead of placing them directly into the WooCommerce folder in that theme). That would be: Theme-Folder/woocommerce-product-addons/addons/template-file.php

Yes! Product Add-Ons can be configured to reduce the price of a product by adding a negative value to the Price field.

Yes, as of version 2.9.0, Product Add-Ons works with Smart Coupons, including the gift card feature.

Yes! Learn more on how the extensions work together here.

Yes, since version 3.4.0.

Product Add-Ons does not have support for conditional logic. If you want to show customers different fields based on information they fill out, we recommend that you use Gravity Forms along with the Gravity Forms Product Add-Ons extension.

No, currently it is not possible to select add-ons for products in manually created orders. You can submit a feature request for this via our Feature Request.

At the moment, quantities can only be set for add-ons created with Quantity field type.

Yes! Documentation for how to work with Product Add-ons via the WC REST API is included within the plugin files.

You can find the documentation by:

• Downloading a .zip of the latest version of Product Add-Ons from your account’s Downloads Page
• Unzipping the folder, then looking in the woocommerce-product-addons/docs/api folder.

More documentation on the WooCommerce REST API can be found here

Note: We are unable to provide support for customizations under our Support Policy. If you need to further customize a snippet, or extend its functionality, we highly recommend Codeable, or a Certified WooExpert.

By default, Product Add-Ons only displays flat fee rates next to the Add-on name on the cart/checkout page. Should you wish to display prices for all price types on the cart/checkout as well as in order/order emails, you can use the following PHP snippets:

For Cart:

add_filter( 'woocommerce_addons_add_cart_price_to_value', '__return_true' );

For Order:

add_filter( 'woocommerce_addons_add_order_price_to_value', '__return_true' );
