如何从woocommerce中的变体ID中检索变体名称？

Question

我用下面的函数调用来获取产品的变化，

$available_variations = $product->get_available_variations(); 

而在返回$ available_variations我所有的变化。

我得到了variation_id，而且我不知道该属性的名称，在本例中属于原产国，那么如何检索属性值，即香港和新加坡在这种情况下？

下面是高于$ available_variations的转储，

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

[image_src] => 
[image_link] => 
[image_title] => 
[image_alt] => 
[price_html] => <span class="price"><span class="amount">SGD$15</span></span>

[is_downloadable] => 
[is_virtual] =>

)

Answer 1

您可以通过使用循环或仅仅作为

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

我知道这是旧的，但只是柜面有人需要这样的获得ID未来，并遇到这个帖子，正确的方法是。

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