   Hello,
   I hope this is a simple question, is it possible to have a loop that displays the parent category, and all posts in it, but organized by sub-categories?

   This page is supposed to work as a catalog, so, it will have several Main Categories that hold many products in sub-categories. The idea is to display each Main Category and show all posts, something like:

   Main category
          Sub-Cat 1
                 Post 1
                 Post 2
                 Post 3
          Sub-Cat 2
                 Post 1
                 Post 2
   etc...

   Should that loop be in the category.php template? I thought about it, and all I can think of is a separate category-slug.php file for each main category, but there has to be a better way.

   Thank you very much for your help!

   Or put it in category.php and use a conditional tag such as is_category(array(5,7,2,12))) to 'wrap around' your code that display the category/sub-cat/post logic.

   I found this post: http://wordpress.org/support/topic/388420?replies=5#post-1529178

   which features this code for category.php, actualy, it's code you wrote about a month ago and Calicosun edited:
   

   <?php
   //get terms (e.g. categories or post tags), then display all posts in each retrieved term
   $taxonomy = 'category';//  e.g. post_tag, category
   $param_type = 'category__in'; //  e.g. tag__in, category__in
   $term_args=array(
     'orderby' => 'name',
     'order' => 'ASC',
     'child_of' => 16
   );
   $terms = get_terms($taxonomy,$term_args);
   if ($terms) {
     foreach( $terms as $term ) {
       $args=array(
         "$param_type" => array($term->term_id),
         'post_type' => 'post',
         'post_status' => 'publish',
         'showposts' => -1,
         'caller_get_posts'=> 1
         );
       $my_query = null;
       $my_query = new WP_Query($args);
       if( $my_query->have_posts() ) {
   
         echo '<li><a href="' . get_category_link( $term->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $term->name ) . '" ' . '>' . $term->name. '</a> ';
   
         while ($my_query->have_posts()) : $my_query->the_post(); ?>
           <ul><li><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></li></ul>
          <?php
                endwhile;
       }
     }
   }
   wp_reset_query();  // Restore global post data stomped by the_post().
   ?>

   This almost works, now the issue is how to have it recognize the category it's in instead of specifying it on the top as 'child_of' => 16

   Thanks for your help!

   You mean like this:

   <?php
   if (is_category( )) {
     $current_cat = get_query_var('cat');
   }
   ?>

   I guess, I'm not good with php, how could I implement that into the code above?

   Edit: I figured it out, thank you very much man!
   Here is the final code that worked

   <?php
   //get terms (e.g. categories or post tags), then display all posts in each retrieved term
   $taxonomy = 'category';//  e.g. post_tag, category
   $current_cat = get_query_var('cat');
   $param_type = 'category__in'; //  e.g. tag__in, category__in
   $term_args=array(
     'orderby' => 'name',
     'order' => 'ASC',
     'child_of' => get_query_var('cat')
   );
   $terms = get_terms($taxonomy,$term_args);
   if ($terms) {
     foreach( $terms as $term ) {
       $args=array(
         "$param_type" => array($term->term_id),
         'post_type' => 'post',
         'post_status' => 'publish',
         'showposts' => -1,
         'caller_get_posts'=> 1
         );
       $my_query = null;
       $my_query = new WP_Query($args);
       if( $my_query->have_posts() ) {
   
         echo '<h4>' . $term->name. '</h4> '; // Sub-Category Title
   
         while ($my_query->have_posts()) : $my_query->the_post(); ?>// Post Contents
   
   Post content here
   	<?php the_title(); ?>
   	<?php the_excerpt(); ?>
   
          <?php
                endwhile;
       }
     }
   }
   wp_reset_query();  // Restore global post data stomped by the_post().
   ?>

   If I understand what you want:
   

   'child_of' => get_query_var('cat')

   Ok, I'm back, I realized that this code only shows categories that have sub-categories, if I try to open a sub-category and display all posts on that sub-category, the page loads blank.

   What can I do about that?

   I don't know much php, so I would think something like:
   

   if (has_children()) {
   		load the code above
   	}
   else {
   		load the regular category.php code
   }

   (I know, I am not a coder so please don't laugh too hard)

   Thanks in advance!
