在 WooCommerce 的电子邮件和订单页面中保存和显示产品自定义数据

Question

我正在使用一些代码来添加自定义字段，以使我的客户能够自定义他们的产品。

这是我当前的代码：

/* 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);

/**
 * Add custom data to Cart
 * @param  [type] $cart_item_data [description]
 * @param  [type] $product_id     [description]
 * @param  [type] $variation_id   [description]
 * @return [type]                 [description]
 */
function rs_add_item_data($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']))
    {
        $cart_item_data['bright_bag_count'] = sanitize_text_field($_REQUEST['bright_bag_count']);
    }

        if(isset($_REQUEST['pastel_bag_count']))
    {
        $cart_item_data['pastel_bag_count'] = sanitize_text_field($_REQUEST['pastel_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]
 * @param  [type] $cart_item [description]
 * @return [type]            [description]
 */
function rs_add_item_meta($item_data, $cart_item)
{

    if(array_key_exists('neutral_bag_count', $cart_item))
    {
        $custom_details = $cart_item['neutral_bag_count'];

        $item_data[] = array(
            'key'   => 'Neutral Bags',
            'value' => $custom_details
        );
    }

    if(array_key_exists('bright_bag_count', $cart_item))
    {
        $custom_details = $cart_item['bright_bag_count'];

        $item_data[] = array(
            'key'   => 'Bright Bags',
            'value' => $custom_details
        );
    }

    if(array_key_exists('pastel_bag_count', $cart_item))
    {
        $custom_details = $cart_item['pastel_bag_count'];

        $item_data[] = array(
            'key'   => 'Pastel Bags',
            'value' => $custom_details
        );
    }

    if(array_key_exists('reg_tendon_count', $cart_item))
    {
        $custom_details = $cart_item['reg_tendon_count'];

        $item_data[] = array(
            'key'   => 'Regular Tendon Sheets',
            'value' => $custom_details
        );
    }

    if(array_key_exists('gid_tendon_count', $cart_item))
    {
        $custom_details = $cart_item['gid_tendon_count'];

        $item_data[] = array(
            'key'   => 'GID Tendon Sheets',
            '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']);
    }
}

单个产品页面上的显示方式如下：

在购物车中：

如何在我的电子邮件模板和订单页面上呈现相同的数据？为了清楚起见，我说的是这些地方：

如有任何提示，我们将不胜感激。

Answer 1

您是否尝试过将数据添加到电子邮件的操作挂钩中？

如果您想在电子邮件中放置代码，我不是 100% 确定，但也许可以尝试这样的操作：

function action_woocommerce_order_item_meta_start( $item_id, $item, $order) { 
   //add your meta values and html here, for example
   $html = 'Pastel Bag Count: '.get_post_meta($order->ID,'_pastel_bag_count',true).'<br />';
}; 

add_action( 'woocommerce_order_item_meta_start', 'action_woocommerce_order_item_meta_start', 10, 3 );

更多钩子请看这里： https://businessbloomer.com/woocommerce-visual-hook-guide-emails/ 现在还有一些（这是 2016 年写的），但是 Woo 的文档可能很难读。

Answer 2

我已经重新访问了您的所有代码并将最后一个函数替换为一个新函数。现在，您将在订单接收页面、我的帐户 > 订单查看页面、订单编辑页面和电子邮件通知中为订单项目显示此自定义字段...

add_action( 'woocommerce_before_add_to_cart_button', 'add_custom_fields_single_product', 20 );

代码进入活动子主题（或活动主题）的 function.php 文件。

已测试并有效。

以下已收到订单，其中填充了 4 个自定义字段 （所以一个为空）：
