我只需要为没有库存的“标签”产品添加一个css样式类。
原始代码示例：
<label class="radio-label sw-radio-variation sw-radio-variation-2" title="l" for="l_2">
我想要的代码：
<label class="out-stock radio-label sw-radio-variation sw-radio-variation-2" title="l" for="l_2">
如您所见，添加到缺货的CSS代码中
我的product-variation.php（我建立这个产品是为了获取库存，但通常只获取库存，而不是从每个姊妹版本中获取）

问题在于，它通常不会获得姐妹变量的库存/数量，而只会获得产品的库存。 我该如何获得所有变化的价值？
谢谢。
