在结帐页面上，我有一个自定义字段，该字段保存到订单元数据中。我需要获取订单元数据，创建自定义帖子类型，并用订单元数据填充自定义字段。

add_action( \'woocommerce_admin_order_data_after_billing_address\', \'my_custom_checkout_field_display_admin_order_meta\', 10, 1 );

function my_custom_checkout_field_display_admin_order_meta($order){
       global $mypass;
 echo \'<p><strong>\'.__(\'My Field\').\':</strong> \' . get_post_meta( $order->id, \'My Field\', true ) . \'</p>\';
   $mypass = get_post_meta( $order->id, \'My Field\', true );
}

以下函数在签出时创建post，但不拉入上面函数中设置的元字段

add_action( \'woocommerce_checkout_update_order_meta\', \'create_custom_post\' );
function create_custom_post($order, $order_id, $posts) {
  global $posts;
$my_post = array(
  \'post_title\'    => \'Page Title\',
  \'post_content\'  => \'This is my post.\',
  \'post_status\'   => \'publish\',
  \'post_type\' => \'sale\',
);
$website_url =  get_post_meta($order_id->id, \'My Field\', true);
$new_post_id = wp_insert_post( $my_post );
update_post_meta($new_post_id, \'My Field\', $website_url );
}

我还尝试在保存元顺序数据的函数上设置一个全局变量

function recent_post_page($order_status, $order_id, $post, $checkout ) {
global $mypass;
  $order = new WC_Order( $order_id );

$my_post = array(
  \'post_title\'    => \'Page title\',
  \'post_content\'  => \'This is my post.\',
  \'post_status\'   => \'publish\',
  \'post_type\' => \'sale\',
);

$new_post_id = wp_insert_post( $my_post );
update_post_meta($new_post_id, \'My Field\', $mypass );

}
add_action( \'woocommerce_payment_complete_order_status\', \'recent_post_page\', 10, 2 );

感谢您的反馈。

get_post_meta($order_id, \'My Field\', true);

get_post_meta($order->ID, \'My Field\', true);
