WooCommerce 有新订单时给客户发送订单邮件

WordPress商城默认woocommerce 在有新订单时只会给管理员邮箱发送邮件，如果我们要实现 有新订单时给客户也发送订单邮件，就需要在functions.php添加代码来实现

解决方案：

WordPress后台–>外观–>主题编辑器–>functions.php 最下方添加上以下代码

add_action('woocommerce_payment_complete', 'my_custom_checkout_field_looking');
function my_custom_checkout_field_looking( $order_id ) {
    $order = new WC_Order( $order_id );

    // first type of Code. Send Email but did not send complete order object.

    $mailer = WC()->mailer();
    $subject = 'New Order Email # ' . $order_id;
    $mailer->send( 'example@gmail.com', $subject, $mailer->wrap_message( $subject, $order ), '', '' );

    // Second type of Code. Do not send email and doing nothing

    global $woocommerce;
    $mailer2 = $woocommerce->mailer();
    // Email customer with order-processing receipt
    $email = $mailer2->emails['WC_Email_Customer_Invoice'];
    $email->trigger( $order );
    // Email admin with new order email
    $email = $mailer2->emails['WC_Email_New_Order'];
    $email->trigger( $order );  
}
