我重新审视了你的代码，例如最后 4 个函数可以合并为一个，还有其他的事情......
数据更新与同步
现在，当客户在我的帐户页面上更新他的数据时，所有数据都会由 woocommerce 同步到各地，除了他现有的过去的命令…
如果客户更改结账字段并处理结账，数据也会随处更新......
So 您无需担心客户同步数据。
Note:该函数挂接在woocommerce_billing_fields将在您的附加注册字段和结帐字段中启用，因为您正在使用结帐对象生成附加注册字段...您可以使用条件! is_checkout()仅针对我的帐户注册字段。
这是您重新访问的代码：
// Custom function to display the Billing Address form to registration page
add_action('woocommerce_register_form_start','zk_add_billing_form_to_registration');
function zk_add_billing_form_to_registration(){
$checkout = WC()->checkout;
foreach ( $checkout->get_checkout_fields( 'billing' ) as $key => $field ) :
if($key!='billing_email')
woocommerce_form_field( $key, $field, $checkout->get_value( $key ) );
endforeach;
}
// Custom function to save Usermeta or Billing Address of registered user
add_action('woocommerce_created_customer','zk_save_billing_address');
function zk_save_billing_address($user_id){
$address = $_POST;
foreach ($address as $key => $field){
// Only billing fields values
if( strpos( $key, 'billing_' ) !== false ){
// Condition to add firstname and last name to user meta table
if($key == 'billing_first_name' || $key == 'billing_last_name'){
$new_key = str_replace( 'billing_', '', $key );
update_user_meta( $user_id, $new_key, $_POST[$key] );
}
update_user_meta( $user_id, $key, $_POST[$key] );
}
}
}
// Checking & validation of the additional fields in registration form.
add_action('woocommerce_register_post','zk_validation_billing_address', 10, 3 );
function zk_validation_billing_address( $username, $email, $validation_errors ){
foreach ($_POST as $key => $field) :
// Validation: Required fields
if( strpos( $key, 'billing_' ) !== false ){
if($key == 'billing_country' && empty($field) ){
$validation_errors->add( $key.'_error', __( 'Please select a country.', 'woocommerce' ));
}
if($key == 'billing_first_name' && empty($field) ){
$validation_errors->add( $key.'_error', __( 'Please enter first name.', 'woocommerce' ) );
}
if($key == 'billing_last_name' && empty($field) ){
$validation_errors->add( $key.'_error', __( 'Please enter last name.', 'woocommerce' ) );
}
if($key == 'billing_address_1' && empty($field) ){
$validation_errors->add( $key.'_error', __( 'Please enter address.', 'woocommerce' ) );
}
if($key == 'billing_city' && empty($field) ){
$validation_errors->add( $key.'_error', __( 'Please enter city.', 'woocommerce' ) );
}
if($key == 'billing_state' && empty($field) ){
if(count( WC()->countries->get_states($_POST['billing_country']) ) > 0)
$validation_errors->add( $key.'_error', __( 'Please enter state.', 'woocommerce' ) );
}
if($key == 'billing_postcode' && empty($field) ){
$validation_errors->add( $key.'_error', __( 'Please enter a postcode.', 'woocommerce' ) );
}
/*
if($key == 'billing_email' && empty($field) ){
$validation_errors->add( $key.'_error', __( 'Please enter billing email address.', 'woocommerce' ) );
}
*/
if($key == 'billing_phone' && empty($field) ){
$validation_errors->add( $key.'_error', __( 'Please enter phone number.', 'woocommerce' ) );
}
}
endforeach;
}
add_filter( 'woocommerce_billing_fields', 'sv_required_billing_fields' );
function sv_required_billing_fields( $fields ) {
$fields['billing_phone']['required'] = true;
$fields['billing_city']['required'] = true;
$fields['billing_country']['required'] = true;
$fields['billing_address_1']['required'] = true;
return $fields;
}
客户无法（永远）访问 WordPress 后端用户编辑页面。只有店长和管理员才能做到...
要在后端同步 WordPress 用户数据，您需要选择哪些字段具有优先级：
- WordPress 默认字段（或）
- 账单字段（来自 WooCommerce）。
最好优先考虑 WordPress 默认字段并隐藏必要的计费字段......
此代码将隐藏 3 个账单字段（名字、姓氏和电子邮件），并将它们与默认字段更新值同步：
// Hidding some billing fields (Wordpress edit user pages)
add_action( 'edit_user_profile', 'user_profile_hide_some_fields_css', 1, 1 );
function user_profile_hide_some_fields_css( $user ){
?>
<style>
.user-edit-php table#fieldset-billing tr:first-child,
.user-edit-php table#fieldset-billing tr:nth-child(2),
.user-edit-php table#fieldset-billing tr:last-child {
display:none;
}
</style>
<?php
}
// Sync hidden billing fields (Wordpress edit user pages)
add_action( 'personal_options_update', 'sync_user_data_wp_and_billing_wc', 100, 1 );
add_action( 'edit_user_profile_update', 'sync_user_data_wp_and_billing_wc', 100, 1 );
function sync_user_data_wp_and_billing_wc( $user_id )
{
if( ! empty($_POST['first_name']) ) {
update_user_meta( $user_id, 'billing_first_name', sanitize_text_field( $_POST['first_name'] ) );
}
if( ! empty($_POST['last_name']) ) {
update_user_meta( $user_id, 'billing_last_name', sanitize_text_field( $_POST['last_name'] ) );
}
if( ! empty($_POST['email']) ) {
update_user_meta( $user_id, 'billing_email', sanitize_text_field( $_POST['email'] ), sanitize_text_field( $_POST['billing_email'] ) );
}
}
代码位于活动子主题（或主题）的 function.php 文件中或任何插件文件中。
经过测试并有效...
