wordpress - woocommerce_checkout_update_order_meta 操作不起作用

Question

嗨，今天我正在与 woo-commerce 合作，我已经根据用户要求成功创建了一些自定义结帐字段，但我无法将它们保存在数据库中。

在这里我如何创建自定义结帐字段...它在子主题中 functions.php

add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
// Over Ridding, Removing, Creating New Fields.
function custom_override_checkout_fields( $fields ) {
     unset($fields['billing']['billing_company']);
     unset($fields['billing']['billing_address_2']);    
     unset($fields['order']['order_comments']);
     unset($fields['billing']['billing_address_1']);
     unset($fields['billing']['billing_city']);
     unset($fields['billing']['billing_postcode']);
     unset($fields['billing']['billing_email']);


     $fields['billing']['your_name'] = array(
    'type'      => 'text',
    'label'     => __('Full Name', 'woocommerce'),
    'placeholder'   => _x('Full Name', 'placeholder', 'woocommerce'),
    'required'  => false,
    'class'     => array('form-row-wide'),
    'clear'     => true
     );

     $fields['billing']['your_phone_number'] = array(
    'type'      => 'text',
    'label'     => __('Your Phone Number', 'woocommerce'),
    'placeholder'   => _x('Your Phone Number', 'placeholder', 'woocommerce'),
    'required'  => false,
    'class'     => array('form-row-wide'),
    'clear'     => true
     );

     $fields['billing']['recipient_name'] = array(
    'type'      => 'text',
    'label'     => __("Recipient's Name", 'woocommerce'),
    'placeholder'   => _x("Recipient's Name", 'placeholder', 'woocommerce'),
    'required'  => false,
    'class'     => array('form-row-wide'),
    'clear'     => true
     );

     $fields['billing']['recipient_company_name'] = array(
    'type'      => 'text',
    'label'     => __("Recipient's Company (if any)", 'woocommerce'),
    'placeholder'   => _x("Recipient's Company (if any)", 'placeholder', 'woocommerce'),
    'required'  => false,
    'class'     => array('form-row-wide'),
    'clear'     => true
     );

     $fields['billing']['recipient_phone_number'] = array(
    'type'      => 'text',
    'label'     => __("Recipient's Phone Number", 'woocommerce'),
    'placeholder'   => _x("Recipient's Phone Number", 'placeholder', 'woocommerce'),
    'required'  => false,
    'class'     => array('form-row-wide'),
    'clear'     => true
     );

     $fields['billing']['recipient_address'] = array(
    'type'      => 'text',
    'label'     => __("Recipient's Address", 'woocommerce'),
    'placeholder'   => _x("Recipient's Address", 'placeholder', 'woocommerce'),
    'required'  => false,
    'class'     => array('form-row-wide'),
    'clear'     => true
     );

     return $fields;
}

在我正在寻找字段的数据库中。它的 wp_postmeta table 。附件是我正在使用订单 ID 搜索的屏幕截图。


现在我添加了 checkout_update_order_meta更新订单元数据并存储我自定义创建的字段的操作。但它似乎不起作用，因为当我登记时 wp_postmeta带有最新创建的订单 ID 的表 我在那里找不到我的自定义字段。

add_action( 'woocommerce_checkout_update_order_meta', 'some_custom_checkout_field_update_order_meta' );

function some_custom_checkout_field_update_order_meta( $order_id ) {


if ( ! empty( $_POST['recipient_address'] ) ) {
add_post_meta( $order_id, 'recipient_address', sanitize_text_field( $_POST['recipient_address'] ) );
}
if (!empty($_POST['recipient_phone_number'])) {
        update_post_meta($order_id, 'recipient phone number', sanitize_text_field($_POST['recipient_phone_number']));
    }

}

这是我第一次处理 woocommerce 代码，我搜索了很多，然后在我放弃它时来到这里。请帮我解开这个谜。

请纠正我我做错了什么。同样在这一步之后，我将不得不在 woocommerce > 订单 > 订单详细信息下的 wordpress 仪表板中显示这些自定义字段，所以如果有任何有用的链接，请提供。

提前致谢。

我只是稍微改变了你最后一个 Hook 的函数，它可以工作(在 WC 版本 2.6.x 和 3.0+ 上)。最好用 empty() php 函数来使用变量(与复古兼容)。
也最好使用 update_post_meta() 而不是 add_post_meta() 因为此功能将确保 meta_key 已经存在，如果不存在， add_post_meta() 将被称为...

Here a screenshot of the wp_postmeta table related to the order meta data:

如果 meta_key 不要像这里这样以下划线开头，它出现在自定义字段元框的后端订单编辑页面中:

这是这段代码:

add_action( 'woocommerce_checkout_update_order_meta', 'saving_checkout_cf_data');
function saving_checkout_cf_data( $order_id ) {

    $recipient_address = $_POST['recipient_address'];
    if ( ! empty( $recipient_address ) )
        update_post_meta( $order_id, 'recipient_address', sanitize_text_field( $recipient_address ) );

    $recipient_phone_number = $_POST['recipient_phone_number'];
    if ( ! empty( $recipient_phone_number ) )
        update_post_meta($order_id, 'recipient_phone_number', sanitize_text_field( $recipient_phone_number ) );

}

代码位于事件子主题(或主题)的 function.php 文件或任何插件文件中。

If you want to have a meta_key starting by _billing… like classic billing checkout fields, you just need to change that in update_post_meta() function. For example:

update_post_meta( $order_id, '_billing_recipient_address', sanitize_text_field( $recipient_address ) );

But in this case, this will not appear in the custom Fields metabox in the order edit page.
