仅针对挂单状态和特定付款方式发送定制的新订单通知

Question

我正在尝试仅针对“待定”订单状态而非“货到付款”付款方式发送有关新订单的通知。但是当客户选择货到付款付款时，管理员会收到重复的邮件，因为 Woocommerce 将此订单状态从“待定”更新为“已处理”。

// New order notification only for "pending" order status and not "cash on delivery" payment method

add_action( 'woocommerce_checkout_order_processed', 'pending_new_order_notification', 10, 1 );
function pending_new_order_notification( $order_id ) {
    // Get an instance of the WC_Order object
    $order = wc_get_order( $order_id );
    $payment_title = $order->get_payment_method_title();

    // Only for "pending" order status and not Cash on delivery payment method 
    if( ! $order->has_status( 'pending' )  && ( $payment_title != 'cod' ) ) return;

    // Get an instance of the WC_Email_New_Order object
    $wc_email = WC()->mailer()->get_emails()['WC_Email_New_Order'];

    ## -- Customizing Heading, subject (and optionally add recipients)  -- ##
    // Change Subject
    $wc_email->settings['subject'] = __('{site_title} - Новый заказ ({order_number}) - {order_date} ожидает оплату');
    // Change Heading
    $wc_email->settings['heading'] = __('Новый заказ'); 
    $wc_email->settings['recipient'] .= ',name@email.com'; // Add email recipients (coma separated)

    // Send "New Email" notification (to admin)
     $wc_email->trigger( $order_id );
}

您的代码中存在一些错误和遗漏的内容，因此请尝试以下操作：

// Send email
add_action( 'woocommerce_checkout_order_processed', 'pending_custom_new_order_notification', 20, 3 );
function pending_custom_new_order_notification( $order_id, $posted_data, $order ) {
    // Only for "pending" order status and not Cash on delivery payment method 
    if( $order->has_status( 'pending' ) && 'cod' !== $order->get_payment_method() ) {
        // Send "New Order" email
        $wc_email = WC()->mailer()->get_emails()['WC_Email_New_Order']->trigger( $order_id );
    }
}

// Custom email subject
add_filter( 'woocommerce_email_subject_new_order', 'custom_new_order_email_subject', 20, 2 );
function custom_new_order_email_subject( $formated_subject, $order ){
    // Only for "pending" order status and not Cash on delivery payment method 
    if( $order->has_status( 'pending' ) && 'cod' !== $order->get_payment_method() ) {
        $formated_subject = sprintf( __('%s - Новый заказ (%s) - %s ожидает оплату', 'woocommerce'), 
            get_bloginfo( 'name' ),
            $order->get_order_number(), // Order ID (or the order number)
            $order->get_date_modified()->date_i18n('F j, Y') // Formatted date modified
        );
    }
    return $formated_subject;
}

// Custom email heading
add_filter( 'woocommerce_email_heading_new_order', 'custom_new_order_email_heading', 20, 2 );
function custom_new_order_email_heading( $heading_txt, $order ){
    // Only for "pending" order status and not Cash on delivery payment method 
    if( $order->has_status( 'pending' ) && 'cod' !== $order->get_payment_method() ) {
        $heading_txt = __('Новый заказ', 'woocommerce');
    }
    return $heading_txt;
}

// Custom email recipient
add_filter( 'woocommerce_email_recipient_new_order', 'custom_new_order_email_recipient', 20, 2 );
function custom_new_order_email_recipient( $recipient, $order ){
    // Only for "pending" order status and not Cash on delivery payment method 
    if( $order->has_status( 'pending' ) && 'cod' !== $order->get_payment_method() ) {
        $recipient .= ',name@email.com';
    }
    return $recipient;
}

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