Get current category ID of the active page

Question

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.

$category = single_term_title("", false);
$catid = get_cat_ID( $category );

$category is displaying "Entertainment" for example. But I also need the ID of "Entertainment". How would I go about this?

Answer 1

You can try using get_the_category():

$categories = get_the_category();
$category_id = $categories[0]->cat_ID;

Answer 2

If it is a category page,you can get id of current category by:

$category = get_category( get_query_var( 'cat' ) );
$cat_id = $category->cat_ID;

If you want to get category id of any particular category on any page, try using :

$category_id = get_cat_ID('Category Name');

Answer 3

The oldest but fastest way you can use is:

$cat_id = get_query_var('cat');

Answer 4

I use the get_queried_object function to get the current category on a category.php template page.

$current_category = get_queried_object();

Jordan Eldredge is right, get_the_category is not suitable here.

Answer 5

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

I think the most direct and simple way to access the cat ID in a category page is:

$wp_query->query_vars['cat']

Answer 6

if you need the category ID, you would get it via get_query_var, that is capable of retrieving all publicly queryble variables.

$category_id = get_query_var('cat');

here is an example to get the category name

$category_name = get_query_var('category_name');

and of course the all mighty get_queried_object

$queried_object = get_queried_object();

that is returning the complete taxonomy term object (when used on a taxonomy-archive page..)

Answer 7

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.

$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.

Answer 8

I used this for breadcrums in the category template page:

$cat_obj = $wp_query->get_queried_object();
$thiscat_id = $cat_obj->term_id;
$thiscat = get_category($thiscat_id);
$parentcat = get_category($thiscat->parent);

Answer 9

Alternative -

 $catID = the_category_ID($echo=false);

EDIT: Above function is deprecated please use get_the_category()

Answer 10

$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;
  }
}

Answer 11

Tried above for solutions to find cat ID of a post, but nothing worked, used the following instead:

$obj = get_queried_object();
$c_id = wp_get_post_categories($obj->ID);
