Ready to start displaying products with custom fields & taxonomies? But before we dive in, let's quickly examine how to create and display a WooCommerce custom product taxonomy.

What is product taxonomy?

A product taxonomy is a means of structuring products into different groups and subgroups based on their features, attributes, and characteristics. It enables customers to find the products they want without wasting time. It also helps you as a seller organise your products, which makes it easier to manage your inventory, sales and marketing effort.

The categorization can be based on size, colour, style, materials, target market, price range, or anything else.

What is a WooCommerce custom taxonomy?

In WooCommerce, a custom taxonomy organizes and classifies products to show advanced custom fields beyond the standard product categories and tags. It allows you to group products based on specific product attributes using hierarchical or non-hierarchical groupings.

To create a custom taxonomy in WooCommerce programmatically, you might have to use a new set of labels. Besides, you'll have to register the taxonomy with the WordPress core and associate the taxonomy you wish to classify.

An easier option is to create a WooCommerce taxonomy using a WordPress plugin. You can use a plugin to create custom taxonomies such as brands, sizes, seasons, materials, and other relevant product data.

What are the benefits of using WooCommerce custom taxonomies?

Using WooCommerce custom taxonomies provides many benefits. These include better product organization, enhanced filtering, improved navigation, flexibility, and higher visibility. Integrating relevant keywords in your custom taxonomy terms enables more laser-focused product pages for better SEO.

What's the difference between WooCommerce custom fields and taxonomies?

We usually use the phrases 'custom fields' and 'custom taxonomies' in relation to WooCommerce product data. However, many people don't know exactly what they are and their differences. WooCommerce custom fields are used to store arbitrary, one-off information about a product. On the other hand, custom taxonomy is used for grouping things together. This reflects in the way you add custom fields and custom taxonomies for products in the WordPress admin:

Custom fields appear in the main column of the Add/Edit Product screen. This is where you add other unique product data such as title, description, price, etc.

In contrast, custom taxonomies appear in the right-hand column under the product categories and tags. Each WooCommerce taxonomy term should be selected for multiple products like categories and tags.

When should I use custom fields & when should I use a WooCommerce taxonomy?

Once you understand the difference between a WooCommerce custom field and taxonomy, it becomes more obvious when to use each one.

As a rule of thumb, you can decide between custom fields and taxonomies by asking: "Is the data I am adding unique to each product, or does it apply to multiple products?" If the data is unique for each WooCommerce product, you need a custom field. However, if you want to select the same value for several products and use it to group them together (e.g., via a product filter), then you need a WooCommerce taxonomy.

Here are some examples to help you choose:

• WooCommerce clothes store displaying the color of each product. If you're selling clothes in WooCommerce, you'll probably want customers to be able to find products by color. You'll have multiple products of each color. By creating a WooCommerce custom taxonomy called 'Colour', customers can filter the list of products to find the color they like. This wouldn't be possible with a custom field.
• WooCommerce second-hand site storing 'condition' information about their used products. If you're selling used goods like eBay, you'll need a field to store details of any damage, etc. The description of each item's condition will be unique to that product, so you should create a WooCommerce custom field.
• WooCommerce product directory with a large product database. WooCommerce directory-style websites with large numbers of products often list extra product data within the directory listings view. For example, a book directory might include data for author, publisher, and year.

Use custom fields and taxonomies together

To use the 2nd example above, a store selling used goods might want a WooCommerce taxonomy called 'Condition' AND a custom field called 'Condition Description'. The 'Condition' taxonomy would include the terms "New," "As New," and "Used," which apply to multiple products.

You could create product filters so customers can narrow their search based on the overall condition. The 'Condition Description' custom field would provide unique information about the exact condition of the product and any damage.

Video tutorial - WooCommerce custom fields & taxonomies

In this video tutorial, you can watch us create WooCommerce taxonomies and custom fields and display them on a WordPress website. There are also full written instructions below:

How to create a WooCommerce custom taxonomy

Easy Post Types and Fields is the best plugin for creating a custom taxonomy for WooCommerce products. It's 100% free and has everything you need to add extra taxonomies to your store.

WooCommerce products are custom post types in WordPress. That's why you need a plugin which lets you add taxonomies to a WordPress post type.

Other plugins like Advanced Custom Fields (ACF) let you create custom fields but not taxonomies. Easy Post Types and Fields lets you do both.

Next, I'll show you how to create WooCommerce custom taxonomies with the free Easy Post Types plugin. After that, you'll learn how to display them on the front end, and how to let customers filter by taxonomy.

Setup instructions

Here's how to use Easy Post Types as a WooCommerce custom taxonomy plugin:

1. 1. Go to Plugins → Add New in the WordPress admin and search for 'Easy Post Types and Fields'.
   2. Install and activate the plugin by Barn2. Skip through the setup wizard because you don't need to create a new post type.
   3. Go to the 'Post Types' section on the left of the WordPress admin and click on the 'Existing Post Types' tab.
   4. Find the 'Products' post type and click on the Taxonomies button for it.
   5. Now set up your WooCommerce custom taxonomy:
      1. Add the Taxonomy Slug (ideally 1 word, lowercase).
      2. Add a plural and singular name (label). This will only appear in the WordPress admin.
      3. Choose whether or not you want the custom taxonomy to be hierarchical. Hierarchical taxonomies are like product categories, where you can create multi-level nested structures with parent and child categories. Non-hierarchical taxonomies are like tags, which are flat and can't be structured.
      4. Click to add the taxonomy to WooCommerce.

Now go to the Edit Product page, and you'll see the custom taxonomy on the right-hand side, under the categories and tags. Add one or more taxonomy terms for each product, just like standard product tags.

You'll also see a section for managing your new WooCommerce taxonomy under the 'Products' section of the WordPress admin. For example, if you created a taxonomy called 'Brand' then a 'Brands' link will appear there.

Displaying WooCommerce custom taxonomies on the front end

Editing the template files for your products' taxonomy archive pages is ideally the only way to display custom taxonomies for WooCommerce products. However, this involves a bit of coding knowledge.

But the good news is that there's a handy WordPress plugin to list products in a table and extra data, such as WooCommerce custom taxonomies. It's an ideal way to display products with extra information, as everything is presented in a structured tabular format. You can add product tables to any WordPress page, your main WooCommerce shop or product category pages, or even a single product page.

The WooCommerce Product Table WordPress plugin is one of the best for displaying custom taxonomies. This is because it supports all the usual WooCommerce product data, plus custom fields and custom taxonomies. Each item of product data is listed as a separate column in the table.

Customers can search or sort the table by any product custom taxonomy term. They can also filter by taxonomy via handy dropdown lists above the table. The WordPress plugin allows you to create WooCommerce tables with only products as a specific taxonomy term.

Comparatively, this is much easier than modifying your WooCommerce template files. Moreover, you get all the other benefits from product table layouts, such as improved conversion rates.

How to create product tables with WooCommerce custom taxonomies

Setting up a WooCommerce Product Table with all the extra product data is easy:

1. Get WooCommerce Product Table. Download the WordPress plugin using the link on the order confirmation page and email.
2. In the WordPress admin, go to Plugins → Add New. Upload the plugin files, and install and activate the plugin.
3. Navigate to Products → Product Tables and set up your first table.

Below, I'll tell you which settings to choose to display WooCommerce custom taxonomies in different ways.

Display custom taxonomies on the WooCommerce shop page or product category archive

The first page of the product table builder lets you choose which method you'll use to add the table. Select the "Display on a shop page (e.g. main storefront, category page, etc.)" option.

On the following page, choose which templates to display the custom taxonomies table on.

Use the 'Columns' page of the table builder to choose what product data to display. All the custom taxonomies for the 'Products' post type in your store will appear in the list of columns. Select as many as you need, and use the pencil icon to rename the column heading.

This will add the product table to your main shop page and whichever other template pages you selected. The list of products will include the WooCommerce custom taxonomies.

How to list products with WooCommerce taxonomies on a standard page

Alternatively, you can add product tables to normal WordPress pages with custom taxonomy columns. This will look similar to the screenshot above, but won't affect your main shop pages.

The instructions for this are mostly the same as above. However, you should select "Add to a page using a block or shortcode" at the start of the table builder.

On the following page, either leave it set to "All products" or select which products you wish to list in the table.

The final page of the table builder will provide a shortcode for adding the table to a page. Either insert this onto the page, or add a 'Product Table' Gutenberg block and select the table you just created.

The page will then display a product table complete with columns for the WooCommerce custom taxonomies.

How to show WooCommerce custom taxonomies on the single product page

You can also use the shortcode method described above to show custom taxonomies on the single product page. However, you need to do it a bit differently because we only want to show one product in each table.

This time, use the 'Select products' page of the table builder to select which individual product you'll be displaying the WooCommerce custom taxonomies on.

On the 'Columns' page of the table builder, add custom taxonomy columns and don't bother with other columns like 'Name'. That's because this information is already present on the single product page.

You can then paste the table's shortcode onto the single product page, for example in the short description field. This will display the WooCommerce custom taxonomies for the selected product. In this screenshot, there are columns for a custom field called 'size', a custom taxonomy called 'fabric', and a stock column. I have hidden elements such as the search box which aren't needed on the single product page (you can do this at Products → Product Tables → Settings).

List WooCommerce products with a specific custom taxonomy term

By default, your WooCommerce product tables will list all the products in a table. This is perfect if you plan to have a single table listing your entire WooCommerce inventory.

However, you can also create product tables listing products from a specific category, tag, custom field, or WooCommerce custom taxonomy term.

To do this, use the 'Select products' page of the table builder to select which taxonomy terms you want to display the products for. When you enable the 'Select specific products' option, the list will automatically include all the custom taxonomies for the 'Products' post type on your store. Select a taxonomy (e.g. Brand in the screenshot below) and then which term(s) you wish to display the products for ('Woo' or 'Ninja' in my example).

Let customers filter by WooCommerce taxonomy

So far, we've talked about how to display WooCommerce custom taxonomies on your website. In addition to this, your customers can benefit from being able to filter the list of products by taxonomy. Product filter by custom taxonomy allows customers to easily find whatever product they're looking for.

There are two ways to add taxonomy filters, depending on whether or not you're already using WooCommerce Product Table to display your taxonomies.

Use WooCommerce Product Table to add taxonomy filter dropdowns

WooCommerce Product Table comes with taxonomy filters which you can display as dropdown lists above the list of products. You can add a separate filter for each custom taxonomy (plus other data such as attributes, variations, categories and tags - instructions here). Customers choose a taxonomy term from the dropdown and use it to filter the list of products.

You can create WooCommerce product filter by custom taxonomy in the table builder. Your WooCommerce custom taxonomies will appear in the list of available filters. Add as many as you like. 

Add advanced WooCommerce taxonomy filters with the Product Filter plugin

For more advanced and flexible custom taxonomy filters, you can use the WooCommerce Product Filters plugin. This comes with many taxonomy filters, including checkboxes, radio buttons, clickable images, range sliders, and much more.

The WooCommerce Product Filters plugin offers a wide range of customization options for displaying taxonomy filters. You can choose from different styles such as checkboxes, dropdowns, images, image labels, or even color swatches. This means that you can create a taxonomy filter that matches your store's design and makes it easy for customers to find the products they are looking for.

For example, if you have a clothing store and want to allow customers to filter products by color, you could use color swatches as the taxonomy filter. This way, customers can easily click on the color swatch they want and see all the products available in that color.

Alternatively, if you have a store that sells products of different sizes, you could use a dropdown menu as the taxonomy filter. This would allow customers to select their preferred size and see all the products available in that size.
