如果订单中有产品处于延期交货状态 - 将订单拆分，并从原来的订单中创建新的延期交货状态。

Question

我有自定义的订单状态，它的工作。

我在这里需要帮助的是循环检查订单项目，检查是否有任何项目处于延期交货状态，如果有，则将延期交货的项目从原始订单中取出，然后创建一个新的订单，并给新订单以 Backorder 状态。

我们的想法是，如果且仅当原始订单中有物品处于延期交货状态时，才创建延期交货状态。

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' );
}

下面的代码只创建一个新的订单，其中的产品是延期交货，如果原来的订单包含产品的延期交货状态。

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();

    // check whether order contains back orders
    $check_for_back_orders = false;

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

        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 = wc_create_order();
            }

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

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

    $order->calculate_totals();
    $order->save();

    // If order contains backorders (true)
    if ( $check_for_back_orders ) {
        $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' );
    }
}
