Get current category ID of the active page
提问by RonnieT
Looking to pull the category ID of a specific page in WordPress that is listing all posts using that specific category. Tried the below but not working. I am able to get the category name using single_term_title.
希望在 WordPress 中提取特定页面的类别 ID，该页面列出了使用该特定类别的所有帖子。尝试了以下但不起作用。我可以使用single_term_title.
$category = single_term_title("", false);
$catid = get_cat_ID( $category );
$categoryis displaying "Entertainment" for example. But I also need the ID of "Entertainment". How would I go about this?
$category例如显示“娱乐”。但我也需要“娱乐”的ID。我该怎么办？

I use the get_queried_object function to get the current category on a category.php template page.
我使用 get_queried_object 函数在 category.php 模板页面上获取当前类别。
$current_category = get_queried_object();
Jordan Eldredge is right, get_the_category is not suitable here.
Jordan Eldredge 是对的，get_the_category 不适合这里。

I think some of the above may work but using the get_the_category function seems tricky and may give unexpected results.

I used this for breadcrums in the category template page:
我在类别模板页面中将其用于面包屑：
$cat_obj = $wp_query->get_queried_object();
$thiscat_id = $cat_obj->term_id;
$thiscat = get_category($thiscat_id);
$parentcat = get_category($thiscat->parent);

I found this question whilst looking for exactly what you asked. Unfortunately you have accepted an incorrect answer. For the sake of other people who are trying to achieve what we were trying to achieve, I thought I'd post the correct answer.
我在寻找您所问的内容时发现了这个问题。不幸的是，您接受了一个不正确的答案。为了其他试图实现我们想要实现的目标的人，我想我会发布正确的答案。
$cur_cat = get_cat_ID( single_cat_title("",false) );
As you said single_term_title("", false);was correctly returning the category title, I'm not sure why you would have had troubles with your code; but the above code works flawlessly for me.
正如您所说的single_term_title("", false);正确返回类别标题，我不确定为什么您的代码会遇到问题；但上面的代码对我来说完美无缺。

$cats = wp_get_post_terms( $post->ID, 'product_cat' );
foreach($cats as $cat){
/*check for category having parent or not except category id=1 which is wordpress default category (Uncategorized)*/
if($cat->parent != '0' && $cat->term_id != 1){
echo '<h2 class="link"><a href="'.get_category_link($cat->term_id ).'">'.$cat->name.'</a></h2>';
break;
}

Tried above for solutions to find cat ID of a post, but nothing worked, used the following instead:
在上面尝试了查找帖子的 cat ID 的解决方案，但没有任何效果，而是使用以下内容：
$obj = get_queried_object();
$c_id = wp_get_post_categories($obj->ID);
