WooCommerce, a popular plugin for WordPress, provides a robust framework for managing products and organizing them in various ways. Among these methods, taxonomies play a crucial role in categorizing products beyond the standard categories and tags. Custom taxonomies allow users to define specific classifications to better organize their products according to business needs. This article explores how to add a custom taxonomy term to products in WooCommerce, offering a structured approach to enhancing product categorization.
In WordPress, a taxonomy is a way to group posts and custom post types together. WooCommerce extends this functionality to products, allowing store owners to create and assign terms that can briefly describe varying characteristics, features, or types of products. By default, WooCommerce includes built-in taxonomies such as product categories and product tags. However, sometimes the built-in taxonomies might not meet specific requirements, necessitating the use of custom taxonomies.
For instance, a store selling clothing might want to classify products based on sizes, materials, or styles. Therefore, one could create custom taxonomies like “Size” or “Material” to enhance filtering and searching capabilities on the site. To explore the nuances of product categorization further, you can refer to plant categorization and products.
The first step to adding custom taxonomy terms to WooCommerce products involves creating the custom taxonomy itself. This can be achieved by adding a code snippet to the theme's functions.php file or creating a custom plugin. The following example demonstrates how to register a custom taxonomy called “Material”:
function create_custom_taxonomy() {
register_taxonomy(
'material',
'product',
array(
'label' => __( 'Material' ),
'rewrite' => array( 'slug' => 'material' ),
'hierarchical' => true,
)
);
}
add_action( 'init', 'create_custom_taxonomy' );
In this code, the register_taxonomy function defines the custom taxonomy along with several arguments like label, rewrite, and hierarchical. The argument hierarchical set to true allows it to behave similarly to categories, enabling parent-child relationships.
Once a custom taxonomy is created, the next step is to add terms to that taxonomy. This can be done programmatically or through the WordPress interface. For instance, to add terms such as “Cotton”, “Polyester”, and “Silk” to the “Material” taxonomy, one can use the following code:
function add_material_terms() {
wp_insert_term( 'Cotton', 'material' );
wp_insert_term( 'Polyester', 'material' );
wp_insert_term( 'Silk', 'material' );
}
add_action( 'init', 'add_material_terms' );
This code utilizes the wp_insert_term function, allowing multiple terms to be added programmatically during the init phase of WordPress. For more insights on product classification, take a look at product classification methods.
After creating and populating your custom taxonomy, the next step is to assign these terms to specific WooCommerce products. This can be done either through the admin product edit page or programmatically. To showcase how to programmatically assign a term to a product, consider the following example:
function assign_material_term_to_product( $product_id ) {
wp_set_object_terms( $product_id, 'Cotton', 'material' );
}
add_action( 'save_post_product', 'assign_material_term_to_product' );
This code binds the term “Cotton” to the specific WooCommerce product when it is saved. Adequate management of taxonomy terms can greatly enhance a user’s shopping experience, making it easier to find the desired products. For further reading on organizing products, refer to product categorization benefits.
After successful assignment, the custom taxonomy terms must be displayed on the product page or within product listings. This improves user experience by letting customers filter and understand product descriptions better. You can achieve this by editing your theme files. For instance, adding the following code snippet within the product template:
$product_materials = get_the_terms( get_the_ID(), 'material' );
if ( ! empty( $product_materials ) ) {
foreach ( $product_materials as $material ) {
echo '' . esc_html( $material->name ) . '';
}
}
This loop fetches the terms linked to the custom taxonomy “Material” and displays them accordingly. The end result will allow your customers to see the materials associated with each product clearly.

Adding a custom taxonomy term to products in WooCommerce provides businesses with a dynamic tool to categorize and manage their offerings effectively. Not only does this facilitate a better shopping experience for customers, but it also conveys information that is not included in the standard product attributes. By leveraging the coding features available in WordPress, one can build a flexible and organized product taxonomy structure tailored to specific needs. For those interested in further organization strategies in eCommerce, consider checking classification of products for additional insights.
Custom taxonomies ultimately support an adaptable shopping environment where users can find products that align more closely with their preferences and needs. Embracing this taxonomical approach in your WooCommerce store not only enhances product visibility but may also streamline your overall inventory management and product discovery processes.
