   I am having a small problem but was hoping maybe someone can help me with it. I am displaying the number of posts in a certain category within the header of my site. IE: Category Name (12).

   On the main index page and the search results page and the posts page its working PERFECTLY, but if I go into a category page for some reason the number blanks out. IE: Category Name ()

   This is the code I am using to display the number, maybe someone can point out why it wouldn't show the number on category pages as well?

   Thank you in advance,
   LawMaker

   <?php
   $cat = get_query_var('cat');
   $categories=get_categories('include=5'.$cat);
   if ($categories) {
     foreach($categories as $category) {
       echo '' . $category->count;
     }
   }
   ?>

   Note: include=5 is the category ID.

   outside the category archive, this line does not return anything:
   $cat = get_query_var('cat');
   and therefore does not disturb this
   get_categories('include=5'.$cat);
   what this 'include=5'.$cat does is to concatenate 'include=5' and the result from the first line, which is the category id of your category archive; for instance 17 - so you get:
   get_categories('include=517');
   which mostly would not exist, and therefore will not return a count.

   where is this get_categories('include=5'.$cat); coming from?
   what is this line supposed to do?
   how is the variable $cat to interact with the number 5?
   is $cat needed at all?

   Well to be perfectly honest. I found the code through google a while ago. Im not very good with PHP and I am learning as I go along so I am not really 100% sure what those lines do. All I know was I needed to change the #5 to be the ID of the category in which I want to show the number of posts inside that cateogory.

   That is really all I am attemping to do. If a certain category ID has 37 posts that I want the number 37 to be displayed.

   Please let me know if I can give you any more info, if I did not anwser your question here.

   Thank you in advance

   from your description, it is not really clear to me, where you want to display what category;

   if you want to use the code in the loop for posts on the front page (index.php) or archive pages (archive.php) then you could for instance use:

   get_the_category()
   http://codex.wordpress.org/Function_Reference/get_the_category
   

   <?php
   $cats = get_the_category();
   
   foreach( $cats as $cat ) {
       echo '' . $cat->count;
   break; //limit output to one category
   
   }
   ?>

   if you want to display it at the top of a category archive, your code could stay as it is - just delete the number 5.

   I know im doing a very poor job describing what im trying to do. Here is more of a visual:

   Category Name One (12 Posts)
   Category Name Two (4 Posts)
   Category Name Three (6 Posts)

   Where 12/4/ and 6 is above, I need to dynamically update when a new post is added to that category.

   Note: Category Name One, Category Name Two, and Category Three are hard coded text, I just need the number to be displayed dynamically. I got it working on all pages with my code except the specific category pages where IE: If we are on the category name two page it would show "Category Name Two ( Posts)"

   Thanks again for the help,
   LawMaker

   step 1:
   get the category id from the category name:
   $cat = get_cat_ID('Category Name');
   http://codex.wordpress.org/Function_Reference/get_cat_ID

   step 2:
   get category info from the categeory id:
   $category = get_category( $cat );
   http://codex.wordpress.org/Function_Reference/get_category

   step 3:
   output the category count:
   echo $category->count;

   in total:
   for each line of hardcoded text, add following code once (with the category name replaced with your own);

   <?php
   $cat = get_cat_ID('Category Name');
   $category = get_category( $cat );
   echo ' ' . $category->count;
   ?>
