拆分 WooCommerce 订单并创建新订单（如果原始订单有延期交货的产品）

Question

我有自定义订单状态并且有效。

我在这里需要帮助的是遍历订单项并检查是否有延期交货，如果是，从原始订单中取出延期交货项并创建一个新订单并为新订单提供Backorder状态。

我们的想法是当且仅当原始订单中有延期交货商品时才创建延期交货。

add_action( 'woocommerce_checkout_order_processed', 'split_order_if_order_has_backorder_products', 10, 1 );
function split_order_if_order_has_backorder_products( $order_id ) {
    if( ! $order_id ) return;

    // get order object
    $order = new WC_Order( $order_id );

    // get order currency
    $currency = $order->get_currency();

    // get order payment method
    $payment_gateway = $order->get_payment_method();

    // get order items = each product in the order
    $items = $order->get_items();

    foreach ( $items as $item ) {       
        $product = wc_get_product( $item['product_id'] );

        if ( $product->is_on_backorder() ) {

        // THIS IS NOT WORKING FOR SOME REASON?
        $backorder = wc_create_order();         
        $backorder->add_product( $product, $item['quantity'] );
        }
    }

    // THIS IS NOT WORKING EITHER = I NEED TO REMOVE THE BACKORDER ITEMS FROM THE ORIGINAL ORDER, RECALCULATE AND SAVE THE NEW TOTAL
    foreach($items as $backorder_product => $item){
        $order->remove_item($backorder_product);
        $order->calculate_totals();
        $order->save();
    }

    $address = array(
        'first_name' => $order->get_billing_first_name(),
        'last_name'  => $order->get_billing_last_name(),
        'email'      => $order->get_billing_email(),
        'phone'      => $order->get_billing_phone(),
        'address_1'  => $order->get_billing_address_1(),
        'address_2'  => $order->get_billing_address_2(),
        'city'       => $order->get_billing_city(),
        'state'      => $order->get_billing_state(),
        'postcode'   => $order->get_billing_postcode(),
        'country'    => $order->get_billing_country()
    );

    $shipping = array(
        'first_name' => $order->get_shipping_first_name(),
        'last_name'  => $order->get_shipping_last_name(),
        'address_1'  => $order->get_shipping_address_1(),
        'address_2'  => $order->get_shipping_address_2(),
        'city'       => $order->get_shipping_city(),
        'state'      => $order->get_shipping_state(),
        'postcode'   => $order->get_shipping_postcode(),
        'country'    => $order->get_shipping_country()
    );

    // Set addresses
    $backorder->set_address( $address, 'billing' );
    $backorder->set_address( $shipping, 'shipping' );

    // set the correct currency and payment gateway
    $backorder->set_currency($currency);
    $backorder->set_payment_method($payment_gateway);

    // calculate totals
    $backorder->calculate_totals();

    // set order note with original ID
    $backorder->add_order_note('Automated Backorder. Created from the original order ID: '.$order->get_id());

    // give the new backorder the correct status
    $backorder->update_status( 'backorder' );
}

如果原始订单包含有延期交货状态的产品，下面的代码只会创建一个包含延期交货产品的新订单。

最后更新：02/22 - 在 WordPress 5.9 和 WooCommerce 6.2.0 中测试

function action_woocommerce_checkout_order_processed( $order_id, $posted_data, $order ) {
    // Initialize
    $check_for_back_orders = false;

    // Loop through order items
    foreach ( $order->get_items() as $item_key => $item ) {
        // Get product
        $product = $item->get_product();

        // Product is on backorder
        if ( $product->is_on_backorder() ) {
            // Will only be executed once if the order contains back orders
            if ( $check_for_back_orders == false ) {
                $check_for_back_orders = true;

                // Create new order with backorders
                $backorder_order = wc_create_order();
            }

            // Add product to 'backorder' order
            $backorder_order->add_product( $product, $item['quantity'] );

            // Delete item from original order
            $order->remove_item( $item->get_id() );
        }
    }

    // If current order contains backorders, retrieve the necessary data from the existing order and apply it in the new order
    if ( $check_for_back_orders ) {
        // Recalculate and save original order
        $order->calculate_totals();
        $order->save();
        
        // Obtain necessary information
        // Get address
        $address = array(
            'first_name' => $order->get_billing_first_name(),
            'last_name'  => $order->get_billing_last_name(),
            'email'      => $order->get_billing_email(),
            'phone'      => $order->get_billing_phone(),
            'address_1'  => $order->get_billing_address_1(),
            'address_2'  => $order->get_billing_address_2(),
            'city'       => $order->get_billing_city(),
            'state'      => $order->get_billing_state(),
            'postcode'   => $order->get_billing_postcode(),
            'country'    => $order->get_billing_country()
        );

        // Get shipping
        $shipping = array(
            'first_name' => $order->get_shipping_first_name(),
            'last_name'  => $order->get_shipping_last_name(),
            'address_1'  => $order->get_shipping_address_1(),
            'address_2'  => $order->get_shipping_address_2(),
            'city'       => $order->get_shipping_city(),
            'state'      => $order->get_shipping_state(),
            'postcode'   => $order->get_shipping_postcode(),
            'country'    => $order->get_shipping_country()
        );
        
        // Get order currency
        $currency = $order->get_currency();

        // Get order payment method
        $payment_gateway = $order->get_payment_method();
        
        // Required information has been obtained, assign it to the 'backorder' order
        // Set address
        $backorder_order->set_address( $address, 'billing' );
        $backorder_order->set_address( $shipping, 'shipping' );

        // Set the correct currency and payment gateway
        $backorder_order->set_currency( $currency );
        $backorder_order->set_payment_method( $payment_gateway );

        // Calculate totals
        $backorder_order->calculate_totals();

        // Set order note with original ID
        $backorder_order->add_order_note( 'Automated backorder. Created from the original order ID: ' . $order_id );

        // Optional: give the new 'backorder' order the correct status
        //$backorder_order->update_status( 'backorder' );
    }
}
add_action( 'woocommerce_checkout_order_processed', 'action_woocommerce_checkout_order_processed', 10, 3 );
