使用wc_update_order_item_meta更新产品差异价格

Question

我试图更新woocommerce订单商品价格，如果它是一个可变产品。

我遇到的问题是它似乎只是获得了woocommerce产品变体的第一个价格，并且即使它的变化不同，它也会使用顺序中的每个项目变化，它应该从正确的变异ID获得价格但是我不确定我错过了什么？

以下代码：

    function update_variable_product_price( ){

        $query = new WC_Order_Query( array(
            'status' => 'on-hold',
            'orderby' => 'date',
            'order' => 'DESC',
            'return' => 'ids',
        ) );
        $order_ids = $query->get_orders();

        foreach( $order_ids as $order_id ) {


            $order = new WC_Order($order_id);
            $items = $order->get_items();


            echo "Order Number: ". $order_id;
            echo "</br>";
            echo "Product Name: ". $order_id["name"];
            echo "</br>";


            foreach ($items as $item) {

                $product_name = $item->get_name();
                $product_id = $item->get_product_id();
                $product_variation_id = $item->get_variation_id();
                $product_variation_price = $item->get_total();
                $product = new WC_Product_Variable($product_id);#1 Get product variations
                $product_variations = $product->get_available_variations();
                $product_qty = $item['qty'];

                echo "</br>-----------------";
                echo "Product Name: " . $product_name;
                echo "</br>";
                echo  "Qty".$product_qty;
                echo "</br>";
                echo "Product Price: " . $product_variation_price;
                echo "</br>";
                echo "Product ID: " . $product_id;
                echo "</br>";
                echo "Variation ID: " . $product_variation_id;
                echo "</br>";
                var_dump($product_variations)  ;
                echo "</br>";


                foreach ($product_variations as $product_variation) {
                    $variation_product_id = $product_variation ['variation_id'];

                    $variation_product = new WC_Product_Variation($variation_product_id);


                    echo "</br>";
                    echo $variation_product->get_price();
                    echo "</br>";
                    echo $variation_product->get_id();
                    echo "</br>";
                    if (isset($product_variation_id)){

                        if($product_id == $product_variation_id) {
                            return wc_update_order_item_meta($item->$product_id, $product_variation_id, $variation_product->get_price());
                        }


                    }
                }
            }  
}
}
