在woocommerce主题中，我试图在产品缺货时发出警告。类似这样：

<?php if (\'this_product_is_out_of_stock\'): ?>
    <p>This product is out of stock. It can be purchased by custom made order.</p>
<?php endif; ?>

是否有一个函数来表示“this\\u product\\u Is\\u out\\u of\\u stock”或其他方式来实现它？

我搜索woocommerce api文档失败：https://docs.woocommerce.com/wc-apidocs/

提前谢谢你。

    global $product;
    if ( ! $product->managing_stock() && ! $product->is_in_stock() )
    echo \'<p>This product is out of stock. It can be purchased by custom made order.</p>\';
