Woocommerce, get current product id
提问by shparkison
I'm currently working on a WooCommerce theme and attempting to add a sidebar to the product detail page.
我目前正在研究 WooCommerce 主题并尝试向产品详细信息页面添加侧边栏。
I've been able to get the sidebar added (specifically, this one: http://woocommerce.wp-a2z.org/oik_file/templatescontent-widget-product-php/)
我已经能够添加侧边栏（特别是这个：http: //woocommerce.wp-a2z.org/oik_file/templatescontent-widget-product-php/）
Now, I'm trying to figure out how to add a class of "active" to the currently selected product and can't seem to figure it out?
现在，我想弄清楚如何向当前选定的产品添加一类“活动”，但似乎无法弄清楚？
In other words, how do I do something along the lines of if the current product id is equal to the product id in the sidebar add class="active" to the li?
换句话说，如果当前产品 id 等于侧栏中的产品 id 添加 class="active" 到 li，我该如何做？
I've made numerous searches and haven't been able to come up with anything useful, so I'm turning here.
我已经进行了多次搜索，但没有找到任何有用的东西，所以我转向这里。
Any help greatly appreciated!!
非常感谢任何帮助！！

2017 Update:
2017年更新：
global $product;
$id = $product->get_id();
Woocommerce doesn't like you accessing those variables directly. This will get rid of any warnings from woocommerce if your wp_debug is true.
Woocommerce 不喜欢您直接访问这些变量。如果您的 wp_debug 为真，这将消除来自 woocommerce 的任何警告。

If the query hasn't been modified by a plugin for some reason, you should be able to get a single product page's "id" via
如果查询由于某种原因没有被插件修改，您应该能够通过以下方式获取单个产品页面的“id”
global $post;
$id = $post->ID
OR
或者
global $product;
$id = $product->id;
EDIT: As of WooCommerce 3.0 this needs to be
编辑：从 WooCommerce 3.0 开始，这需要是
global $product;
$id = $product->get_id();

Since WooCommerce 2.2you are able to simply use the wc_get_productMethod. As an argument you can pass the IDor simply leave it empty if you're already in the loop.
由于 WooCommerce2.2您可以简单地使用该wc_get_product方法。作为参数ID，如果您已经在循环中，您可以传递或简单地将其留空。
wc_get_product()->get_id();
wc_get_product()->get_id();
OR with 2 lines
或 2 行
$product = wc_get_product();
$id = $product->get_id();

Retrieve the ID of the current item in the WordPress Loop.
检索 WordPress 循环中当前项目的 ID。
echo get_the_ID();
hence works for the product id too. #tested #woo-commerce
因此也适用于产品 ID。#tested #woo-commerce

Save the current product id before entering your loop:
在进入循环之前保存当前产品 ID：
$current_product = $product->id;
Then in your loop for your sidebar, use $product->id again to compare:
然后在侧边栏的循环中，再次使用 $product->id 进行比较：
<li><a <? if ($product->id == $current_product) { echo "class='on'"; }?> href="<?=get_permalink();?>"><?=the_title();?></a></li>
