Woocommerce中通过变体可变属性ID获取属性slug值

    global $product;

    if($product->is_type('variable')){

        $variations = $product->get_available_variations();

        foreach($variations as $variation)

        {

            $variation_obj = wc_get_product($variation['variation_id']);

            // Variation can have many poduct attributes

            $attr_slugs = implode(', ', $variation['attributes']);

            $stock = $variation_obj->get_stock_quantity();

            $COD = $variation_obj->get_sku();

            $regularprice = $variation_obj->get_regular_price();

            $saleprice = $variation_obj->get_sale_price();

            $diff = $regularprice-$saleprice;

            echo "<p>Var Name: " .$attr_slugs."</p>";

            echo "<p>Var Name: " .$COD."</p>";

            echo "<p>regular price: ".$variation['display_regular_price']."</p>";

            echo "<p>sale price: ".$saleprice."</p>";

            echo "<p>risparmi: ". $diff."</p>";

            echo "<p>in stock: ".$stock."</p>";

        }
