Is it possible for the_category to display a post count within a post.

Looks like Posted In: Category Name (3),Category Name (2) etc etc

Possible or not?

I would just use wp_list_categories but it needs to appear on a post by post basis like this post is posted in category x and y not just all of them...

How about this...

add_filter('get_the_categories', 'wpse50876_the_counter');

function wpse50876_the_counter($cats){
foreach($cats as $cat){
    $cat->cat_name = $cat->cat_name.'('.$cat->count.')';
}
return $cats;
}

Try it...

Good implementation of my solution +1 :D You should probably prefix your function names though, the_counter() is so generic it's likely to get redefined, something like wpse50876_the_counter() has a MUCH smaller chance of that happening. – m0r7if3r May 2 '12 at 13:24
Hehe yeah! Changed the function name! – Rutwick Gangurde May 2 '12 at 13:34

You should be able to hook get_the_categories to modify the name property of each category with a count of the number of objects with that count, which should be available in the category_count property (all of this assuming that I followed the code right).

Make sure that when you hook, you add the filter, do your call to the_category() then remove it immediately, as there may be other functions that you're using which depend on get_the_category().

+1. I was going to suggest this - however, the filter would apply to all instances of get_the_category. This may not be an issue. Otherwise, you'll have to create your own function... – Stephen Harris May 2 '12 at 13:03

If you do something like add_filter(); the_category(); remove_filter(); it doesn't apply it to all instances, just the one you want. – m0r7if3r May 2 '12 at 13:07
that's a good call :) – Stephen Harris May 2 '12 at 13:14
I've found myself using that method more and more recently...it really amplifies just how powerful wordpress hooks are. – m0r7if3r May 2 '12 at 13:22
