   I have a site that is comprised of categories and sub-categories. I'd like to have only the category's child posts display on the category.php page. I'm using the following to order posts, so I think there's a way to add the category__in parameter, but I haven't been able to figure out how.
   

   <?php
     $cat_title = single_cat_title('', false);
     $cat_id = get_cat_ID($cat_title);
   
       $wp_query->set('orderby', 'category');
       $wp_query->set('order', 'ASC');
       $wp_query->get_posts();  
   
       get_posts('orderby=category&order=ASC'); ?>
   <?php if (have_posts()) : ?>
   etc.

   $cat_id is to obtain the current category's ID to use limiting to that category, but as I said, I can't figure out how to do it. If there's another approach to accomplish this, that would be fine, too.

   Thanks.

   Try this

   <?php
   
   query_posts("order_by=category&category__in=array(1,2,3)")
   
   ?>

   I changed the first bit of code to:
   

   $wp_query->set('orderby', 'menu_order');
       $wp_query->set('order', 'ASC');
       $wp_query->set('category__in', array(4));
       $wp_query->get_posts();
       get_posts("orderby=menu_order&order=ASC&category__in=array(4)"); ?>
   	<?php if (have_posts()) : ?>

   But I get the same results: all posts from all sub-categories of category 4 get displayed.

   <?php
   get_posts("orderby=menu_order&order=ASC&child_of=4");
   ?>

   Try above code.

   I figured out how to accomplish my purpose: listing posts for categories that have them and listing sub-categories for parent categories that have no posts. Here is the whole template for anyone else that might benefit from it.
   

   <?php // Category.php, template for listing sub-categories or category posts ?>
   
   <?php get_header(); ?>
   <?php
     $cat_title = single_cat_title('', false);
     $category_id = get_cat_ID($cat_title);
       $wp_query->set('orderby', 'menu_order');
       $wp_query->set('order', 'ASC');
       $wp_query->get_posts();
       get_posts("orderby=menu_order&order=ASC"); ?>
   <?php if ( in_category($category_id) ) : ?>
   	<?php if (have_posts()) : ?>
   		<?php $post = $posts[0]; // Hack. Set $post so that the_date() works. ?>
   		<h2 class="pagetitle">
   			<?php if (is_category()) { ?>
   				Index for ‘<?php single_cat_title(); ?>’
           <?php } ?>
   		</h2>
   		<div class="list-page">
   			<?php while (have_posts()) : the_post(); ?>
   				<div <?php post_class() ?>>
   					<h3><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h3>
   				</div>
   			<?php endwhile; ?>
   		</div>
   <?php
   endif;
   ?>
   	<?php else :
   		if ( is_category() ) {  // If this is a category archive ?>
   		<h2 class="pagetitle">
   				Index for ‘<?php single_cat_title(); ?>’
           <?php $category_link = get_category_link( $category_id ); ?>
   		</h2>
   		<div class="list-page">
         <ul>
         <?php wp_list_categories('orderby=name&child_of=4&title_li='); ?>
         </ul>
   		</div>
   		<?php }
       endif;
   ?>
   	<?php get_sidebar(); ?>
   <?php get_footer(); ?>

   Hope that helps

   The whole magic is actually here: if ( in_category($category_id) ) :. Thank you man! I lost almost a day in searching for a solution and you saved my day!

   I don't know why but query_posts('category__in=' . $category_id); actually doesn't work. So the workaround is putting the above if statment before the Loop.

   Great for sharing it!
