在 WooCommerce 中显示基于自定义 table 的自定义字段值

Question

我有一段代码可以在感谢页面上显示自定义字段值，但它不显示该值。但是我能够在后端管理页面上显示该值。下面是我的代码：

add_action( 'woocommerce_thankyou_order_received_text', 'additionalnote_order_data_in_admin', 10, 1    );
function additionalnote_order_data_in_admin( $order ){
    global $wpdb;
    global $post_id;
    
    $order = new WC_Order( $post_id );

    $table_name = $wpdb->prefix . 'woocommerce_custom_fields';

    $result = $wpdb->get_results("SELECT * FROM $table_name ");

    if(!empty($result)){

        foreach($result as $query){
            $name = $query->name;
            $label = $query->label;
            $get_order = $order->get_meta('_'.$name);

            echo '<p><strong>'.__('Delivery Date').':</strong> ' . $get_order . '</p>';
        }
    }
}

您的代码中存在一些错误……请改用以下代码：

add_action( 'woocommerce_thankyou_order_received_text', 'additional_note_order_data_in_admin', 10, 1    );
function additional_note_order_data_in_admin( $order_received_text, $order ){
    global $wpdb;

    $order_id = $order->get_id(); // Get order Id (For info, If needed)

    $results = $wpdb->get_results("SELECT * FROM {$wpdb->prefix}woocommerce_custom_fields");

    if ( ! empty($results) ) {
        foreach ( $results as $result ) {
            if ( $meta_value = $order->get_meta( '_'.$result->name ) ) {
                $order_received_text .= '</p><p><strong>' . __('Delivery Date') . ':</strong> ' . $meta_value;
            }
        }
    }
    return $order_received_text;
}

代码进入活动子主题（或活动主题）的 functions.php 文件。它应该更好用。
