如何從woocommerce中的變體ID中檢索變體名稱？

Question

我用下面的函數調用來獲取產品的變化，

$available_variations = $product->get_available_variations(); 

而在返回$ available_variations我所有的變化。

我得到了variation_id，而且我不知道該屬性的名稱，在本例中屬於原產國，那麼如何檢索屬性值，即香港和新加坡在這種情況下？

下面是高於$ available_variations的轉儲，

(
[variation_id] => 2968 
[attributes] => Array 
    (
     [attribute_pa_country-of-origin] => hong-kong 
    ) 

[image_src] => 
[image_link] => 
[image_title] => 
[image_alt] =>

Answer 1

您可以通過使用循環或僅僅作爲

echo $available_variations[0]['variation_id']; 
echo $available_variations[1]['variation_id']; 
echo $available_variations[2]['variation_id']; 
echo $available_variations[3]['variation_id']; 

Answer 2

我知道這是舊的，但只是櫃面有人需要這樣的獲得ID未來，並遇到這個帖子，正確的方法是。

echo $available_variations[0][attributes][attribute_pa_country-of-origin]; 
echo $available_variations[1][attributes][attribute_pa_country-of-origin];
