添加自定义电子邮件Woocommerce

Question

我有一个插件管理我的货件与两个自定义状态：等待-装运和装运。

我尝试添加一个电子邮件发送时，订单传递到发货。

我在Stack Overflow：Woocommerce退款电子邮件中发现了这一点，但我可以知道它是如何工作的

下面是我的插件文件代码:
我用下面的helgatheviking和Adrien Leber的建议更新了我的代码

function shippement_tracking_filter_actions( $actions ){
    $actions[] = "woocommerce_order_status_shipped";
    return $actions;
}
add_filter( 'woocommerce_email_actions', 'shippement_tracking_filter_actions' );

function add_expedited_order_woocommerce_email( $email_classes ) {
    require( 'includes/class-wc-expedited-order-email.php' );
    $email_classes['WC_Expedited_Order_Email'] = new WC_Expedited_Order_Email();
    return $email_classes;
}
add_filter( 'woocommerce_email_classes', 'add_expedited_order_woocommerce_email' );`

和我的班级：

class WC_Expedited_Order_Email extends WC_Email {
    public function __construct() {

        $this->id               = 'expedited_order_tracking';
        $this->customer_email   = true;
        $this->title            = __( 'Shippement Traking', 'customEmail' );
        $this->description      = __( 'Sent tracking email to customer', 'customEmail' );
        $this->heading          = __( 'Your {site_title} order is shipped', 'customEmail' );
        $this->subject          = __( 'Your {site_title} order from {order_date} is shipped', 'customEmail' );

        $this->template_html    = 'emails/customer-order_tracking.php';
        $this->template_plain   = 'emails/plain/customer-order_tracking.php';

        add_action( 'woocommerce_order_status_shipped', array( $this, 'trigger' ) );

        parent::__construct();
    }

    public function trigger( $order_id )
    {
        var_dump($order_id);die();
    }

当我改变我的订单状态时，什么也没有发生！我的触发函数从不调用。

有人能帮我吗？

我想你误解了这一部分：

function add_expedited_order_woocommerce_email( $email_classes ) {
   $email_classes['WC_Expedited_Order_Email'] = include( plugin_dir_path( __FILE__ ) . '/class-wc-expedited-order-email.php' );
   return $email_classes;
}

您必须首先包含类文件,然后创建该类的新实例：

function add_expedited_order_woocommerce_email( $email_classes ) {

    // include our custom email class
    require( 'includes/class-wc-expedited-order-email.php' );

    // add the email class to the list of email classes that WooCommerce loads
    $email_classes['WC_Expedited_Order_Email'] = new WC_Expedited_Order_Email();

    return $email_classes;

}

希望有帮助。
