WooCommerce-将多个项目拆分为单独的行项目

时间：2018-05-30 作者：HectorOfTroy407

我希望在收到订单后，将数量大于1的行项目拆分为单独的行项目。我读了很多关于这方面的书，看到了很多在签出过程发生之前做这件事的好脚本，比如https://businessbloomer.com/woocommerce-display-separate-cart-items-product-quantity-1/ 和https://stackoverflow.com/questions/32485152/woocommerce-treat-cart-items-separate-if-quantity-is-more-than-1?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa.

订单完成后，有人有没有想过该怎么做？还是在WooCommerce中创建订单？我想把任何数量大于1的东西分成单独的行项目。

所以我认为我需要访问所有行项目，然后找到数量大于1的行项目，然后添加新的行项目并减少数量，直到所有项目都平衡。我需要一些帮助的地方是如何创建行项目？我知道我可以检查它们，如下所示：

function inspect_line_items() 
{
  $order = wc_get_order( 390 );
    foreach ($order->get_items() as $item_id => $item_data) {

    // Get an instance of corresponding the WC_Product object
    $product = $item_data->get_product();
    $product_name = $product->get_name(); // Get the product name

    $item_quantity = $item_data->get_quantity(); // Get the item quantity

    $item_total = $item_data->get_total(); // Get the item line total

    // Displaying this data (to check)
    if ($item_quantity >1 ){
        echo \'HALP!\';

      }
    }
}

好的，我正在继续尝试，我已经能够添加行项目（这不是prod，只是测试它，显然这有一些差距：））。这就是说，我可以在结帐后添加一个新项目，然后使用另一个挂钩将订单状态更改回处理状态。现在的问题是显示的价格。即使我减少了特定项目的数量，它仍将显示全部/原始成本。我尝试更新sub\\u total和total字段，然后我得到了这个时髦的折扣：行项目。有什么想法吗？我是这里的正确人选吗？

add_action( \'woocommerce_checkout_create_order\', \'change_total_on_checking\', 20, 1 );
function change_total_on_checking( $order ) {
    // Get order total
    $total = $order->get_total();
    $items = $order->get_items();
    foreach ($order->get_items() as $item_id => $item_data) {

    // Get an instance of corresponding the WC_Product object
        $product = $item_data->get_product();
        $product_id = $item_data->get_id();
        $product_name = $product->get_name();
        $price = $product->get_price();


        $item_quantity = $item_data->get_quantity();
        $item_data[\'quantity\'] = $item_data[\'quantity\'] - 1 ; // Get the item quantity
        //$item_data[\'total\'] = $item_data[\'total\'] - $price;
        //$item_data[\'sub_total\'] = $item_data[\'sub_total\'] - $price;

        $item_total = $item_data->get_total(); // Get the item line total


        //do_action(\'woocommerce_add_to_order\', $item_data[\'id\'], $item_data[\'product_id\'], $item_quantity, $item_data[\'variation_id\']);
        WC()->cart->add_to_cart( $product_id, $item_quantity );
        $order->add_product( $product, 1);
        $order->calculate_totals(); // updating totals

        $order->save(); // Save the order data


    }

}

add_action( \'woocommerce_thankyou\', \'woocommerce_thankyou_change_order_status\', 10, 1 );
function woocommerce_thankyou_change_order_status( $order_id ){
    if( ! $order_id ) return;

    $order = wc_get_order( $order_id );

    $order->update_status( \'processing\' );
}

因此，我最终结合了一些答案，并在添加到购物车以及更新购物车时拆分了订单。下面的内容可以工作，尽管它只是一个前端定制。希望这对其他人有帮助！

function bbloomer_split_product_individual_cart_items( $cart_item_data, $product_id ){
  $unique_cart_item_key = uniqid();
  $cart_item_data[\'unique_key\'] = $unique_cart_item_key;
  return $cart_item_data;
}

add_filter( \'woocommerce_add_cart_item_data\', \'bbloomer_split_product_individual_cart_items\', 10, 2 );  

add_action( \'woocommerce_after_cart_item_quantity_update\', \'limit_cart_item_quantity\', 20, 4 );
function limit_cart_item_quantity( $cart_item_key, $quantity, $old_quantity, $cart ){

    // Here the quantity limit
    $limit = 1;
    $orders_added = $quantity - $limit;

    if( $quantity > $limit ){
        //Set existing line item quantity to the limit of 1
        $cart->cart_contents[ $cart_item_key ][\'quantity\'] = $limit;
        //get product id of item that was updated
        $product_id = $cart->cart_contents[ $cart_item_key ][ \'product_id\' ];

        for( $i = 0; $i< $orders_added; $i++ ){
            //iterate over the number of orders you must as with quantity one
            $unique_cart_item_key = uniqid();
            //create unique cart item ID, this is what breaks it out as a separate line item
            $cart_item_data = array();
            //initialize cart_item_data array where the unique_cart_item_key will be stored
            $cart_item_data[\'unique_key\'] = $unique_cart_item_key;
            //set the cart_item_data at unique_key = to the newly created unique_key

            //add that shit! this does not take into account variable products

            $cart->add_to_cart( $product_id, 1, 0, 0, $cart_item_data );

        }

        // Add a custom notice
        wc_add_notice( __(\'We Split out quantities of more than one into invididual line items for tracking purposes, please update quantities as needed\'), \'notice\' );
    }
}

以下是我找到的解决方案-拆分在订单保存时完成，而不是在购物车级别完成：

add_action( \'woocommerce_after_order_object_save\', array( $this, \'split_order_items\' ), 10, 2 );
function split_order_items( $order, $data_store ) {
    $order_items = $order->get_items();

    foreach ( $order_items as $item ) {

        if ( $item instanceof WC_Order_Item_Product ) {
            $quantity = $item->get_quantity( \'edit\' );
            $product  = $item->get_product();

            if ( $product && 1 < $quantity ) {
                $product = $item->get_product();
                $taxes   = $item->get_taxes();

                WP_Weixin::log( $order->get_item( $item->get_id() ) );

                $order->remove_item( $item->get_id() );

                for ( $i = $quantity; $i > 0; $i-- ) {
                    $new_item  = new WC_Order_Item_Product();
                    $new_taxes = array();

                    if ( ! empty( $taxes ) && is_array( $taxes ) ) {
                        foreach ( $taxes as $taxes_key => $tax_values ) {
                            $new_tax_values = array();

                            if ( ! empty( $values ) && is_array( $values ) ) {

                                foreach ( $values as $tax_key => $tax_value ) {
                                    $new_tax_values[ $tax_key ] = $tax_value / $quantity;
                                }
                            }

                            $new_taxes[ $taxes_key ] = $new_tax_values;
                        }
                    }

                    $new_item->set_product( $product );
                    $new_item->set_backorder_meta();
                    $new_item->set_props(
                        array(
                            \'quantity\'     => 1,
                            \'subtotal\'     => $item->get_subtotal( \'edit\' ) / $quantity,
                            \'total\'        => $item->get_total( \'edit\' ) / $quantity,
                            \'subtotal_tax\' => $item->get_subtotal_tax( \'edit\' ) / $quantity,
                            \'total_tax\'    => $item->get_total_tax( \'edit\' ) / $quantity,
                            \'taxes\'        => $new_taxes,
                        )
                    );
                    $order->add_item( $new_item );
                }
            }
        }
    }

    remove_action( \'woocommerce_after_order_object_save\', array( $this, \'split_order_items\' ), 10 );
    $order->save();
    add_action( \'woocommerce_after_order_object_save\', array( $this, \'split_order_items\' ), 10, 2 );
}

次要的缺点是订单保存了两次（订单项受到保护，必须先保存在数据库中才能访问），这是可以接受的，具体取决于具体情况。在花了几个小时查看源代码之后，这是我所知的唯一方法。

我读了很多以前的代码，我修复了这个，完全后端成本化，我需要这样的东西，我们在每个产品上添加序列号，但我们希望客户能按数量购买，希望对一些人有所帮助，
