Custom fields in WooCommerce allow you to add extra information to your products, giving your customers more detailed information and enhancing the shopping experience. Whether you need to include extra details like color options, product specifications, or custom notes, custom fields can make your products more dynamic and informative.

In this article, we’ll guide you through the process of adding custom fields to WooCommerce products and show you how to display them on the product page.

What Are Custom Fields in WooCommerce?

Custom fields are additional data fields that you can associate with WooCommerce products. They allow you to add specific information that is not included in the default product fields (such as title, description, price, and SKU). This could include anything from additional product attributes, like “Custom Engraving Text,” to specific delivery instructions or additional product options that might not fall under the regular product attributes.

These fields are extremely helpful for businesses that sell highly customizable products or have specific requirements for certain products that aren’t covered by the default WooCommerce fields.

Why Add Custom Fields to WooCommerce Products?

There are several reasons to add custom fields to your WooCommerce products, including:

• Customizing Product Details: Add unique product specifications like size, weight, materials, or personalized options.
• Enhancing User Experience: Provide customers with more detailed and relevant information to improve the shopping experience.
• Better Control Over Product Variations: Customize your product pages to display variations or additional options that are tailored to your store’s needs.
• Data Collection: Capture additional information that may be useful for order processing or customer communication.

How to Add Custom Fields to WooCommerce Products

There are two primary ways to add custom fields to WooCommerce products: using the built-in WooCommerce options and utilizing plugins. Below, we’ll show you both methods.

Method 1: Using the Built-in WooCommerce Product Data

WooCommerce provides a built-in way to add custom fields through the Product Data section of each product. Here’s how you can do it:

1. Log in to Your WordPress Dashboard
   • Navigate to your WooCommerce product editor.
2. Edit a Product
   • Go to Products → All Products and select the product you want to edit, or create a new product by clicking Add New.
3. Access the Product Data Section
   • In the Product Data section, scroll down to the Custom Fields section.
4. Add a Custom Field
   • In the Custom Fields box, click Add Custom Field. You will be prompted to provide a name for the custom field and a value. For example:
     • Name: “Material”
     • Value: “Wood”
5. Save the Product
   • Once you’ve added the custom field, make sure to save your changes by clicking the Update button.
6. Display the Custom Field
   • Now, the custom field is added to your product, but you may need to modify your theme’s template files to display the custom field on the front end.

Method 2: Using a Plugin (Recommended)

For more advanced functionality and easier management, using a plugin to add custom fields is often the best option. Below are some popular plugins you can use:

1. Advanced Custom Fields (ACF)

Advanced Custom Fields (ACF) is one of the most popular and powerful plugins for adding custom fields to WooCommerce products. It gives you complete control over the type and location of the custom fields.

Steps to Add Custom Fields Using ACF:

1. Install and Activate ACF Plugin:
   • Go to Plugins → Add New, search for Advanced Custom Fields, and click Install Now, followed by Activate.
2. Create a Custom Field Group:
   • Go to Custom Fields → Add New to create a new field group.
   • In the field group, click Add Field and choose the type of field (e.g., text, select, image, etc.).
   • Under Location, choose to display the custom fields on Product.
3. Publish the Field Group:
   • After configuring the custom fields, click Publish.
4. Add Custom Field Data to Your Product:
   • Now, go to the Product editing screen in WooCommerce.
   • You’ll see the new custom fields you created under the product editor.
   • Fill in the values for each custom field and save the product.
5. Display the Custom Fields on the Product Page:
   • To display custom fields on the product page, you’ll need to modify the template files (usually single-product.php or content-single-product.php) in your theme.
   • Use the following code to display the custom field:phpCopyEdit<?php the_field('your_custom_field_name'); ?>
   • If you are not comfortable with code, you can use plugins like WooCommerce Customizer or hire a developer to help.

2. WooCommerce Custom Fields Plugin

This plugin provides a straightforward way to add custom fields to your WooCommerce product pages without touching any code.

Steps to Add Custom Fields Using WooCommerce Custom Fields Plugin:

1. Install and Activate the Plugin:
   • Go to Plugins → Add New, search for WooCommerce Custom Fields and install the plugin.
2. Create Custom Fields:
   • After activation, go to Products → Custom Fields.
   • Click Add New to create a custom field and select the type of field you need (e.g., text, select, checkbox, etc.).
   • Choose the location where you want the custom fields to appear (e.g., product pages, cart, checkout).
3. Add Custom Field to Product:
   • After creating the field, you can add the custom field value while editing the product.
4. Display the Custom Field on the Frontend:
   • This plugin handles frontend display automatically, so the custom fields will appear on the product pages once they are added.

How to Display Custom Fields on the Product Page

Once you’ve added custom fields to your WooCommerce products, you’ll likely want them to appear on the product page. There are different ways to display them depending on the method you used to add them.

Method 1: Display Custom Fields Using ACF

If you used Advanced Custom Fields (ACF), you can display your custom fields by editing your theme’s product page template:

1. Locate the Template File:
   • Find the single-product.php or content-single-product.php file in your theme folder.
2. Insert the Custom Field Code:
   • In the appropriate place within the file (usually in the product description section), insert the following code to display the custom field:phpCopyEdit<?php the_field('your_custom_field_name'); ?>
   • Replace 'your_custom_field_name' with the name of the custom field you created.

Method 2: Display Custom Fields Using WooCommerce Custom Fields Plugin

If you are using the WooCommerce Custom Fields plugin, the custom fields are typically displayed automatically once they are added to a product.

However, if you want to customize the display further, you can always edit the template files and add custom HTML or CSS to style the fields to your liking.

Conclusion

Adding custom fields to WooCommerce products can greatly enhance the user experience by providing more detailed information about your products. Whether you choose to use WooCommerce’s built-in custom fields or a plugin like Advanced Custom Fields or WooCommerce Custom Fields, you’ll have the flexibility to tailor your product pages to your exact needs.

If you’re comfortable with coding, you can easily display the custom fields on the product pages. Otherwise, using plugins is a great option for those who want to add custom fields without touching any code.

With custom fields in place, you can offer a more personalized shopping experience, making it easier for customers to find the product information they need to make informed purchasing decisions.

Happy customizing!
