Php 向Woocommerce中处于搁置状态的COD订单发送电子邮件通知

我正在使用wordpress 4.9.5和woocommerce 3.3.5，我希望触发以下付款方式、订单状态和客户邮件

• 贝宝=完成+付款确认电子邮件
• BACS=暂停+订单暂停电子邮件
• COD=暂停+订单暂停电子邮件

在这一点上，除了在使用COD时没有收到“订单保留电子邮件”之外，一切都正常。 订单状态已设置为“暂停”，但暂停电子邮件未发送

这是我正在使用的代码：

add_action( 'woocommerce_thankyou', 'wc_auto_complete_paid_order', 20, 1 );
function wc_auto_complete_paid_order( $order_id ) {
    if ( ! $order_id )
        return;

    // Get an instance of the WC_Product object
    $order = wc_get_order( $order_id );

    // On hold status for orders delivered with Bank wire, Cash on delivery and Cheque payment methods.
    if ( in_array( $order->get_payment_method(), array( 'bacs', 'cod', 'cheque', '' ) ) ) {
        $order->update_status( 'on-hold' );
    // Updated status to "completed" for paid Orders with all others payment methods
    } else {
        $order->update_status( 'completed' );
    }
}

function unhook_new_order_processing_emails( $email_class ) {
        // Turn off pending to processing for now
        remove_action( 'woocommerce_order_status_pending_to_processing_notification', array( $email_class->emails['WC_Email_Customer_Processing_Order'], 'trigger' ) );
        // Turn it back on but send the on-hold email
        add_action( 'woocommerce_order_status_pending_to_processing_notification', array( $email_class->emails['WC_Email_Customer_On_Hold_Order'], 'trigger' ) );
}

首先，您的第二个函数中缺少钩子…它应该是：

add_action( 'woocommerce_email', 'unhook_new_order_processing_emails' );
function unhook_new_order_processing_emails( $email_class ) {
    // Turn off pending to processing for now
    remove_action( 'woocommerce_order_status_pending_to_processing_notification', array( $email_class->emails['WC_Email_Customer_Processing_Order'], 'trigger' ) );
    // Turn it back on but send the on-hold email
    add_action( 'woocommerce_order_status_pending_to_processing_notification', array( $email_class->emails['WC_Email_Customer_On_Hold_Order'], 'trigger' ) );
}

正式文件：

然后，要触发“货到付款”订单的“保留”通知，您可以尝试以下操作：

// Trigger "On hold" notification for COD orders
add_action('woocommerce_order_status_on-hold', 'email_on_hold_notification_for_cod', 2, 20 );
function email_on_hold_notification_for_cod( $order_id, $order ) {
    if( $order->get_payment_method() == 'cod' )
        WC()->mailer()->get_emails()['WC_Email_Customer_On_Hold_Order']->trigger( $order_id );
}

代码放在活动子主题（或活动主题）的function.php文件中）

这太完美了！
