How to enable price and inventory for custom product type in WooCommerce

Question

I created a custom product type in my WooCommerce application

function register_variable_bulk_product_type() {

    class WC_Product_Variable_bulk extends WC_Product_Simple {

        public function __construct($product) {

            $this->product_type = 'variable_bulk';
            parent::__construct($product);
        }

    }

}

add_action('init', 'register_variable_bulk_product_type');

function add_variable_bulk_product($types) {

    $types['variable_bulk'] = __('Variable Bulk');

    return $types;
}

add_filter('product_type_selector', 'add_variable_bulk_product');

This shows product type in product data dropdown like as follows,

My problem is

The new product don't have an option for adding inventory and prices, How can I enable these options?

You need a small JS trick to show Price and Inventory tab, i.e. you need to add class show_if_{your_custom_product_type} in your case it will be show_if_variable_bulk.

Here is the working code:

function wh_variable_bulk_admin_custom_js() {

    if ('product' != get_post_type()) :
        return;
    endif;
    ?>
    <script type='text/javascript'>
        jQuery(document).ready(function () {
            //for Price tab
            jQuery('.product_data_tabs .general_tab').addClass('show_if_variable_bulk').show();
            jQuery('#general_product_data .pricing').addClass('show_if_variable_bulk').show();
            //for Inventory tab
            jQuery('.inventory_options').addClass('show_if_variable_bulk').show();
            jQuery('#inventory_product_data ._manage_stock_field').addClass('show_if_variable_bulk').show();
            jQuery('#inventory_product_data ._sold_individually_field').parent().addClass('show_if_variable_bulk').show();
            jQuery('#inventory_product_data ._sold_individually_field').addClass('show_if_variable_bulk').show();
        });
    </script>
    <?php

}

add_action('admin_footer', 'wh_variable_bulk_admin_custom_js');

Code goes in functions.php file of your active child theme (or theme). Or also in any plugin PHP files.
Code is tested and works.

This is how your general tab will look:

and this is how inventory tab will look

Hope this helps!
