从WooCommerce中的订单项获取变异属性

Question

我试图获得变量product属性的名称，在购物车中，但有些东西不对。我不明白当一个对象被保护时，我怎么能得到变异值

foreach ( $order->get_items() as $item_id => $item ) {
 
     $product_id = $item->get_product_id();
      $product = $item->get_product();
      
$accomodation = $product['variation']['attribute_pa_hebergement']; // does not work

}

这是$product中对象reurns的一部分

WC_Product_Variation Object
(
   [post_type:protected] => product_variation
   [parent_data:protected] => Array
       (
           [title] => test
           [status] => publish
           [sku] => 
      
           [tax_class] => 
           [shipping_class_id] => 0
           
       )

   [object_type:protected] => product
   [cache_group:protected] => products
   [data:protected] => Array
       (
           [name] => test
           [slug] => test-14
         
          ...
           [attributes] => Array
               (
                   [pa_hebergement] => chambre-double-140e
                   [pa_parking] => 1-place-35e
                   [pa_tarifs] => tarif-jeune
               )

           [default_attributes] => Array
               (
               )

相反，请尝试使用wc_product方法get_attributes()如下所示：

// Loop through order items
foreach ( $order->get_items() as $item_id => $item ) {
    // Target product variations
    if ( $item->get_variation_id() ) {
        $product = $item->get_product(); // Get the product Object
        
        // Loop through product attributes
        foreach ( $product->get_attributes() as $attribute => $value ) {
            // Get attribute label name
            $label = wc_attribute_label($attribute);
            
            // Get attribute name value
            $name = term_exists( $value, $attribute ) ? get_term_by( 'slug', $value, $attribute )->name : $value;
            
            // Display
            echo '<p><strong>' . $label . '</strong>: ' . $name . '</p>';
        }
    }
}

应该管用。
