   I'm trying to do the following:

   When the user is browsing a category page, I want to get the current category ID. This is what I'm doing:

   if(is_category() || is_single()){
    foreach(get_the_category() as $category)
    {
     $current =$category->cat_ID;
     $current_name = $category->cat_name;
    }
   }
   
   echo $current_name . " has id ".$current;

   The problem is that when I'm on a category page, get_the_category generates multiple categories, and it's getting the last category output by the function.

   I just want the category ID of the category that is currently displayed in the URL.

   Using the code that you've posted, you'll have the last category on the array (if you use $current_name .= $category->cat_name you'll have a concatenation of these values).

   What about using the function get_category_by_path()?

   Just my two cents…

   FYI:

   if(is_category() || is_single()){
     $cat = get_category_by_path(get_query_var('category_name'),false);
     $current = $cat->cat_ID;
     $current_name = $cat->cat_name;
   
   echo "Current category ID is ".$current." and is called ".$current_name;
   }

   Salaam everybody,
   This code is a bit smarter:
   

   if(is_category() || is_single()){
    $category = end(get_the_category());
    $current =$category->cat_ID;
    $current_name = $category->cat_name;
   }
   echo $current_name . " has id ".$current;

   Cheers,
   Aziz Oraij

   Well I have to say that the code from thepaperdump works correctly but the one from Top7up not. When in parent category it still displays the child.

   Just FYI and thanks to thepaperdump!

   yep, header.php :) or you can put it in a function and call the function in your header, loop, wherever.

    There's a far simpler way.

    if (is_category()) {
    global $wp_query;
    $cat_obj = $wp_query->get_queried_object();
    echo $cat_obj->name . " has id ". $cat_obj->term_id;
    }

    get_queried_object returns the main object that was queried for.

    Great job Otto42 ... I put it in my sidebar ( not widgettized ) and it works very well.

    This is my use of this :

    I added depth=1 in wp_list_categories , so I have a Cat menu without children cat.
    Then I added :

    if(is_category()|| is_single()){global $wp_query;
    $cat_obj = $wp_query->get_queried_object();
    $current_name = $cat_obj->name ;
    $current = $cat_obj->term_id;
    ?><h4><?php echo $current_name . "Has ID =".$current;
    ?></h4><?php echo "and has subcategories as follows :";
    wp_list_categories('orderby=name&show_count=1&title_li=&use_desc_for_title=1&child_of='. $current);}

    That show me the subcategories of current cat ....

    Great !

    Thanks
