GoFuckYourself.com - Adult Webmaster Forum - How to display wordpress popular posts by views of each category?

Hello guys,

Can someone help me with this code?
I want to display most popular posts by views of each category...
I already have a code working but only shows the popular posts of all, not for each category...

Here is my code in single.php file:

PHP Code:


		
			
<?php

foreach(get_the_category(get_the_ID()) as $keys){

    $cu = $keys->cat_name;

}

?>

<h2 class="single-post-external" style="background: #9F0C67; padding: 8px 0 8px 8px;">Most Viewed Posts in <?php echo $cu; ?> Category<?php //echo  "Like ".get_the_title(); ?></h2>    

    <?php setPostViews(get_the_ID()); ?>

    <?php query_posts('posts_per_page=8&meta_key=post_views_count&orderby=meta_value_num&order=DESC'); ?>

    <div id="main_container" class="mrCatouter container  clearfix">

    <?php while ( have_posts() ) : the_post(); ?>

And in my functions.php file I have this:

PHP Code:


		
			
function setPostViews($postID) {    

    $count_key = 'post_views_count';    

    $count = get_post_meta($postID, $count_key, true);    

    if($count==''){        

        $count = 0;        

        delete_post_meta($postID, $count_key);        

        add_post_meta($postID, $count_key, '0');    

    }else{        

        $count++;        

        update_post_meta($postID, $count_key, $count);    

    }

}

I think that I need to change:

Code:

query_posts('posts_per_page=8&meta_key=post_views_count&orderby=meta_value_num&order=DESC');

but I don't have sure what to do...

Hope to see some help here :)

Thank you guys!

Kind regards,

EDIT

I found out that adding a &cat= after DESC and enter the id number for the category it works :)
But I dont want to show a specific category, I want to show the category where the post is in...
Any ideas?
