WooCommerce 订单操作 Metabox 下拉列表中缺少自定义操作

Question

在 this page 的帮助下，我在 WooCommerce 电子邮件中添加了一封额外的电子邮件。我希望它是我可以发送给客户的手动电子邮件，但它没有显示在要发送的电子邮件下拉列表中的顺序中。我猜我错过了什么，但我不知道是什么。这是我使用的插件的代码：

                    'multipart' => __( 'Multipart', 'woocommerce' ),
                )
            )
        );
    }


} // end \WC_Expedited_Order_Email class

我已经注释掉触发器并添加代码使其成为手动客户邮件。

    function is_customer_email() {
        return true;
    }

    function is_manual() {
        return true;
    }

在 WooCommerce 设置中，我看到了邮件，它看起来像是可以发送给客户的手动邮件。邮件模板看起来不错，但我没有在真正发送邮件的顺序中看到下拉列表中的邮件名称。我在这里错过了什么？

Answer 1

您错过了向 "ORDER actions" Metabox 下拉列表添加 "Send Expedited email" 操作，如下所示：

// Adding 'Send Expedited email' to action Metabox dropdown in admin order pages
add_filter( 'woocommerce_order_actions', 'filter_wc_add_send_expedited_email_action', 20, 1 );
function filter_wc_add_send_expedited_email_action( $actions ) {
    $actions['send_expedited_email'] = __( 'Send Expedited email', 'woocommerce' );

    return $actions;
}

// Trigger the email notification on 'Send Expedited email' action (composite hook)
add_action( 'woocommerce_order_action_send_expedited_email', 'trigger_action_send_expedited_email', 20, 1 );
function trigger_action_send_expedited_email( $order ) {
    // Get all WC_emails objects instances
    $wc_emails = WC()->mailer()->get_emails();

    // HERE We define our custom email class name
    $class_name = 'WC_Expedited_Order_Email';

    // Send custom email
    if( class_exists($class_name) ) {
        $wc_emails[$class_name]->trigger( $order->get_id() );
    }
}

代码进入您的活动子主题（或活动主题）的 functions.php 文件。已测试并有效。

I didn't really tried with your custom email code, as the custom related templates are missing from your answer code… You should add your complete code to a public Gist on Github and then add the link to your answer (useful for the community).

Answer 2

我补充了：

function sv_wc_process_order_meta_box_action( $order ) {

    // add the order note
    $message = sprintf( __( 'Herinnering verstuurd door: %s.', 'label20-textdomain' ), wp_get_current_user()->display_name );
    $order->add_order_note( $message );

}
add_action( 'woocommerce_order_action_send_expedited_email', 'sv_wc_process_order_meta_box_action' );

记下执行该操作的用户的用户名。
