Show or hide WooCommerce admin product custom field depending on the product type

Question

I added an custom field to the products

add_action( 'woocommerce_product_options_sku', 'prodcode_fields');

function prodcode_fields() {
    global $post, $thepostid, $product_object;

    echo '<div class="options_prodcode_fields">';
   
    woocommerce_wp_text_input(
        array(
            'id' => '_prodcode_good_number',
            'value' => $product_object->get_meta('_prodcode_number', true),
        'type' => 'number',
            'label' => 'Product Code',
            'desc_tip' => true,
        'description' => __('Product Code', 'sv-prodcode'),
        )  );

echo '</div>';
}

All is well, but it is necessary not to display it in variable goods. Can you tell me how to do it using woocommerce tools?

I tried to add 'class' => 'show_if_simple', but I get nonsense - only input is hidden, but labels and so on remain.

To hide an additional product custom field, you can use 2 approaches:

Using the wrapper_class attribute with "show_if_simple" or "hide_if_variable" like:

• 'wrapper_class' => 'show_if_simple',
• 'wrapper_class' => 'hide_if_variable',

Or you can directly use "show_if_simple" or "hide_if_variable" in the starting <div> like:

echo '<div class="options_prodcode_fields show_if_simple">';

or

echo '<div class="options_prodcode_fields hide_if_variable">';

So in for your code:

add_action( 'woocommerce_product_options_sku', 'display_admin_product_custom_setting_fields');
function display_admin_product_custom_setting_fields() {
    global $product_object;

    // Only for simple product type
    echo '<div class="options_prodcode_fields show_if_simple">';
   
    woocommerce_wp_text_input(
        array(
            'id'            => '_prodcode_good_number',
            'type'          => 'number',
            'label'         => __('Product Code', 'sv-prodcode'),
            'description'   => __('Product code description', 'sv-prodcode'),
            'desc_tip'      => true,
            'value'         => $product_object->get_meta('_prodcode_number'),
        )  );

    echo '</div>';
}
