Php 在WooCommerce存档页面中显示可变产品的库存变化属性

我想在我的store 页面上显示可用的产品变体的属性(有库存的).我的代码完成了这项工作，但我得到的不是属性名称，而是属性的缩写名称，这看起来确实很糟糕.我应该做什么或改变什么？

代码如下所示:

add_action( 'woocommerce_after_shop_loop_item', 'display_loop_item_stock_notice', 90 );
function display_loop_item_stock_notice() {
    global $product, $wpdb;

    $is_in_stock = $product->is_in_stock();
    $backordered = $product->is_on_backorder();
    
    //Dla wariacji:
    if($product->is_type('variable'))
       {
          $stock_qty = $wpdb->get_var("
          SELECT SUM(pm.meta_value) FROM {$wpdb->prefix}posts as p
          JOIN {$wpdb->prefix}postmeta as pm ON p.ID = pm.post_id
          WHERE p.post_type = 'product_variation'
          AND p.post_status = 'publish' AND p.post_parent = '".get_the_id()."'
          AND pm.meta_key = '_stock' AND pm.meta_value IS NOT NULL");
        
        //Dla wariacji w magazynie: 
        if($stock_qty > 0)
        {
            echo '<span style="color:green; font-weight:bold;">  Opcje dostępne z magazynu:</span></br>';
            foreach ( $product->get_available_variations() as $key ) {
            $variation = wc_get_product( $key['variation_id'] );
            $stock = $variation->get_availability();
            $stock_quantity = $variation->get_stock_quantity();
            if($variation->is_in_stock( ) && $stock_quantity > 0)
            {
            $attr_string = array();
                foreach ( $key['attributes'] as $attr_name => $attr_value ) {
                $attr_string[] = $attr_value;
                    echo $variation->attribute_value;
            }
            echo '<span style="color:green;">'. implode( ', ', $attr_string ). ': ' . $stock_quantity. ' sztuk</span> </br>';}
        }
        }
        //Dla braków na magazynie:
        else
        {
            echo $backordered !== 'no' && $stock_qty <= 0 ? '<span style="color:#33b0c7; "> Dostępny na zamówienie </span>' : '<span style="color:red;"> Brak w magazynie</span>';
        }
}       

以下是它在store 页面上的外观:

谢谢你的帮助！
