在WooCommerce的电子邮件和订单页面中保存并显示产品自定义数据

I'm using some code to add custom fields to enable my customers to customize their products.

Here's my current code:

/* Add meta fields to all products */
/* SRC: https://wisdmlabs.com/blog/add-custom-data-woocommerce-order-2/ */

/* Step 1: Adding Custom Field for Product */
add_action('woocommerce_before_add_to_cart_button','rs_add_custom_fields');
/**
 * Adds custom field for Product
 * @return [type] [description]
 */
function rs_add_custom_fields()
{

    global $product;

    ob_start();

    ?>

        <div class="wdm-custom-fields">
            <input type="text" placeholder="neutral_bag_count" name="neutral_bag_count">
            <input type="text" placeholder="bright_bag_count" name="bright_bag_count">
            <input type="text" placeholder="pastel_bag_count" name="pastel_bag_count">
            <input type="text" placeholder="reg_tendon_count" name="reg_tendon_count">
            <input type="text" placeholder="gid_tendon_count" name="gid_tendon_count">
        </div>
        <div class="clear"></div>

    <?php

    $content = ob_get_contents();
    ob_end_flush();

    return $content;
}

/* Step 2: Add Customer Data to WooCommerce Cart */
add_filter('woocommerce_add_cart_item_data','rs_add_item_data',10,3);

/**

 * @param  [type] $cart_item_data [description]

 * @return [type]                 [description]
 */
function rs_add_item_data($cart_item_data, $product_id, $variation_id)
{
    if(isset($_REQUEST['neutral_bag_count']))
    {
        $cart_item_data['neutral_bag_count'] = sanitize_text_field($_REQUEST['neutral_bag_count']);
    }

        if(isset($_REQUEST['bright_bag_count']))
    {

    }

        if(isset($_REQUEST['reg_tendon_count']))
    {
        $cart_item_data['reg_tendon_count'] = sanitize_text_field($_REQUEST['reg_tendon_count']);
    }

        if(isset($_REQUEST['gid_tendon_count']))
    {
        $cart_item_data['gid_tendon_count'] = sanitize_text_field($_REQUEST['gid_tendon_count']);
    }

    return $cart_item_data;
}

/* Step 3: Display Details as Meta in Cart */
add_filter('woocommerce_get_item_data','rs_add_item_meta',10,2);

/**
 * Display information as Meta on Cart page
 * @param  [type] $item_data [description]

function rs_add_item_meta($item_data, $cart_item)
{

    if(array_key_exists('neutral_bag_count', $cart_item))

        $custom_details = $cart_item['neutral_bag_count'];

    if(array_key_exists('gid_tendon_count', $cart_item))

            'value' => $custom_details
        );
    }

    return $item_data;
}

/* Step 4: Add Custom Details as Order Line Items */
add_action( 'woocommerce_checkout_create_order_line_item', 'rs_add_custom_order_line_item_meta',10,4 );

function rs_add_custom_order_line_item_meta($item, $cart_item_key, $values, $order)
{

    if(array_key_exists('neutral_bag_count', $values))
    {
        $item->add_meta_data('_neutral_bag_count',$values['neutral_bag_count']);
    }

    if(array_key_exists('bright_bag_count', $values))
    {
        $item->add_meta_data('_bright_bag_count',$values['bright_bag_count']);
    }

    if(array_key_exists('pastel_bag_count', $values))
    {
        $item->add_meta_data('_pastel_bag_count',$values['pastel_bag_count']);
    }

    if(array_key_exists('reg_tendon_count', $values))
    {
        $item->add_meta_data('_reg_tendon_count',$values['reg_tendon_count']);
    }

    if(array_key_exists('gid_tendon_count', $values))
    {
        $item->add_meta_data('_gid_tendon_count',$values['gid_tendon_count']);
    }
}

Here's how that shows on the single product page:

Here it is in the cart:

How do I get the same data to render in my email templates and on the orders page? For clarity, i'm talking about these places:

Any tips would be appreciated.
