How to Create Custom Product Type in WooCommerce?

In this dev blog article, we will learn how we can create a custom product type in the WooCommerce online store.

Creating a custom product type in WooCommerce can be a more advanced customization, and it usually requires some coding knowledge.

Custom product types allow you to add products with unique features and functionality beyond the standard simple, variable, or grouped product types.

Here’s a general guide on how to create custom product types in WooCommerce:

First of all, create a directory for your new WooCommerce plugin in the plugins directory path i.e. ‘/wp-content/plugins/’.

In my case, the directory name is ‘wkwc-custom-product-type’ you can change your directory name as you want.

Next, Open this folder in your preferred text editor and create a php file like ‘wkwc-custom-product-type.php’.

Put the following header comments in the PHP file to make this a plugin file.

/**
 * Plugin Name: WooCommerce Custom Product Type
 * Description: Create a custom product type.
 * Version: 1.0.0
 * Author: Webkul
 *
 * @package WooCommerce Custom Product Type
 */

You can change the above information to match your details.

Create a new PHP file ‘class-wc-product-wkwc-custom-product.php’ in the ‘plugins/wkwc-custom-product-type/include/’ folder, and define your custom product type. Here’s a basic example:

<?php
/**
 * Define custom product type.
 *
 * @package WooCommerce Custom Product Type
 */

defined( 'ABSPATH' ) || exit(); // Exit if accessed directly.

if ( ! class_exists( 'WC_Product_Wkwc_Custom_Product' ) ) {

	/**
	 * Custom Product class.
	 */
	class WC_Product_Wkwc_Custom_Product extends WC_Product {

		/**
		 * Constructor of this class.
		 *
		 * @param object $product product.
		 */
		public function __construct( $product ) {
			$this->product_type = 'wkwc_custom_product';
			$this->virtual      = 'yes';
			$this->supports[]   = 'ajax_add_to_cart';

			parent::__construct( $product );
		}

		/**
		 * Return the product type.
		 *
		 * @return string
		 */
		public function get_type() {
			return 'wkwc_custom_product';
		}

	}
}

Now, add the below code to the plugin’s main file i.e. ‘wkwc-custom-product-type.php’ for handling the WooCommerce Custom Product Type.

<?php
/**
 * Plugin Name: WooCommerce Custom Product Type
 * Description: Create a custom product type.
 * Version: 1.0.0
 * Author: Webkul
 * Domain Path: /languages
 * Text Domain: wkcp
 *
 * @package WooCommerce Custom Product Type
 */

defined( 'ABSPATH' ) || exit(); // Exit if accessed directly.

// Define Constants.
defined( 'WCPOSGC_PLUGIN_FILE' ) || define( 'WCPOSGC_PLUGIN_FILE', plugin_dir_path( __FILE__ ) );

if ( ! class_exists( 'Wkwc_Custom_Product_Type' ) ) {

	/**
	 * Custom product type class.
	 */
	class Wkwc_Custom_Product_Type {

		/**
		 * Constructor.
		 */
		public function __construct() {
			add_action( 'woocommerce_loaded', array( $this, 'wkwc_load_include_custom_product' ) );

			add_filter( 'product_type_selector', array( $this, 'wkwc_add_custom_product_type' ) );

			add_action( 'woocommerce_wkwc_custom_product_add_to_cart', array( $this, 'wkwc_display_add_to_cart_button_on_single' ), 30 );

			add_filter( 'woocommerce_product_add_to_cart_text', array( $this, 'wkwc_add_to_cart_text' ), 10, 2 );
		}

Once you have added the code to the main plugin file, save the file and activate the plugin in the WordPress admin panel.

To activate the plugin, go to the “Plugins” menu and find the plugin you just created. Click “Activate” to enable the plugin.

To create a custom product, go to WordPress admin Product > Add New & select your custom product type. See the below image:

In the front end, you can see your custom product. Here is the screenshot of your custom product on the WooCommerce single product page:
