WooCommerce：使用自定义电子邮件通知添加自定义订单状态

使用“在WooCommerce 4+应答代码中发送电子邮件通知的添加新订单状态”，我已经能够获得一个自定义状态的电子邮件通知，但是我无法理解如何发送有关以下内容的电子邮件通知：两种自定义状态。

请参阅下面的示例代码和我为多个自定义状态电子邮件通知尝试的代码。我还包含了完整代码，该代码显示了创建多个状态的整个过程。

希望此快速修复有帮助！

另外，对于电子邮件正文-是否有可能通过此代码更改处理订单内容中的内容而无需创建新的电子邮件模板？

工作-单个“自定义状态”电子邮件通知“已发送”

add_filter( 'woocommerce_email_actions', 'filter_woocommerce_email_actions' );
function filter_woocommerce_email_actions( $actions ){
    $actions[] = 'woocommerce_order_status_wc-shipped';
    return $actions;
}
// Send Customer Processing Order email notification when order status get changed from "tree" to "processing"
add_action('woocommerce_order_status_changed', 'shipped_status_custom_notification', 10, 4);
function shipped_status_custom_notification( $order_id, $from_status, $to_status, $order ) {
    if(  'shipped' === $to_status ) {
        // The email notification type
        $email_key   = 'WC_Email_Customer_Processing_Order';
        // Get specific WC_emails object
        $email_obj = WC()->mailer()->get_emails()[$email_key];
        // Sending the customized email
        $email_obj->trigger( $order_id );
    }
}
// Customize email heading for this custom status email notification
add_filter( 'woocommerce_email_heading_customer_processing_order', 'email_heading_customer_shipped_order', 10, 2 );
function email_heading_customer_shipped_order( $heading, $order ){
    if( $order->has_status( 'shipped' ) ) {
        $email_key   = 'WC_Email_Customer_Processing_Order'; // The email notification type
        $email_obj   = WC()->mailer()->get_emails()[$email_key]; // Get specific WC_emails object
        $heading_txt = sprintf( __('Order #%s has been Shipped!', 'woocommerce'), '{order_number}' ); // New subject text
        return $email_obj->format_string( $heading_txt );
    }
    return $heading;
}
// Customize email subject for this custom status email notification
add_filter( 'woocommerce_email_subject_customer_processing_order', 'email_subject_customer_shipped_order', 10, 2 );
function email_subject_customer_shipped_order( $subject, $order ){
    if( $order->has_status( 'shipped' ) ) {
        $email_key   = 'WC_Email_Customer_Processing_Order'; // The email notification type
        $email_obj   = WC()->mailer()->get_emails()[$email_key]; // Get specific WC_emails object
        $subject_txt = sprintf( __('Your %s Order #%s has been Shipped!', 'woocommerce'), '{site_title}', '{order_number}' ); // New subject text
        return $email_obj->format_string( $subject_txt );
    }
    return $subject;
}
