如何禁用Woocommerce待处理(on-hold)订单邮件并发送处理中订单邮件

Got it, let's fix this email flow for your BACS orders. Here's exactly how to disable the default on-hold email and send the processing order email instead when the order is marked as on-hold:

1. Confirm/Disable the Default On-Hold Email #

First, make sure you've turned off the default on-hold email via the WooCommerce admin (you mentioned this is already done, but just to recap):

• Head to WooCommerce > Settings > Emails
• Find the "On Hold Order" email entry
• Uncheck the "Enable this email notification" box and hit save

If you need to restrict this disablement only for BACS orders (in case other gateways still need the on-hold email), use this code snippet instead:

add_filter( 'woocommerce_email_enabled_customer_on_hold_order', 'disable_bacs_on_hold_email', 10, 2 );
function disable_bacs_on_hold_email( $enabled, $order ) {
    // Check if the order uses BACS gateway
    if ( $order->get_payment_method() === 'bacs' ) {
        $enabled = false;
    }
    return $enabled;
}

2. Send Processing Order Email for BACS On-Hold Orders #

Next, we'll hook into the order status change to trigger the processing email when a BACS order goes to on-hold status. Add this code to your child theme's functions.php file or a custom plugin:

add_action( 'woocommerce_order_status_on-hold', 'send_bacs_processing_email', 10, 2 );
function send_bacs_processing_email( $order_id, $order ) {
    // Only target BACS orders
    if ( $order->get_payment_method() !== 'bacs' ) {
        return;
    }

    // Get the processing order email instance
    $processing_email = WC()->mailer()->get_emails()['WC_Email_Customer_Processing_Order'];
    
    // Trigger the email
    if ( isset( $processing_email ) ) {
        $processing_email->trigger( $order_id );
    }
}

How This Works: #

• The first snippet either globally disables the on-hold email (via admin) or specifically turns it off for BACS orders (via code).
• The second snippet listens for when an order is set to on-hold, checks if it's a BACS order, then triggers the processing order email that's normally sent when orders are marked as paid.

Make sure to test this flow with a test BACS order to confirm everything works as expected!
