   Hoping there is a guru who could tweak this code or provide something new.

   I need to break down and list all posts in a category AND it's subcategories. The following code only lists posts in the sub cats, so any post in the main category is skipped. So close though. Help?

   [please mark your code using the 'code' button or backticks;
   next time, please, for any code of more then 10 lines, use the pastebin]

   <?php
       $parentCatName = single_cat_title('',false);
       $parentCatID = get_cat_ID($parentCatName);
       $childCats = get_categories( 'child_of='.$parentCatID );
       if(is_array($childCats)):
       foreach($childCats as $child){ ?>
       <h2><?php echo $child->name; ?></h2>
       <?php query_posts('cat='.$child->term_id);
       while(have_posts()): the_post(); $do_not_duplicate = $post->ID; ?>
       <!-- POST CODE -->
   
       <!-- END POST CODE -->
       <?php
       endwhile;
       wp_reset_query();
       }
       endif;
       ?>

   Any luck on this? I've been trying for a while now to do the same thing, without success.

   unless you need to have the posts ordered by category with the category name on top -
   the 'normal' query should do it:

   <?php
       $parentCatID = get_cat_ID(single_cat_title('',false));
           <?php query_posts('cat='.$parentCatID);
       while(have_posts()): the_post(); $do_not_duplicate = $post->ID; ?>
       <!-- POST CODE -->
   
       <!-- END POST CODE -->
       <?php
       endwhile;
       wp_reset_query();
           ?>

   (untested)

   Hey Alchymyth, thanks but yes that's what I'm after, the sub-categories listed, but including the top level as well :) Trickier than I thought...

   this might work:

   open to dealing with details:
   - the edit simply integrates the parent category into the array;
   - do you need to mark the parent category (not done in the current version)?
   - are you planning to use the '$do_not_duplicate' variable?
   - are you aware that 'cat= ' will also query posts of child categories?

   Hey Alchy,

   Thank you so much for your help. Sorry, I've only just had a chance to look at this.

   Very close! My only problem now is that the child categories are listed under the main section, and then again under their child section - see >

   The 'cat=' query doing that? Sorry I'm no expert :(

   Hola,

   Did you achieve what you wanted to achieve? I'm not sure what you want to list ...

   Bunny hi! Sorry I never got your post. No I am STILL trying to fix.

   If you look at the list -
   http://www.kawikadesign.com/domains/tubularequipment.co.nz/Catalogue/01-walking-frames/

   the first four items are actually subcategories. They display again under their subcategories at the bottom. I really just need these to display only under the subcats. The rest is perfect.

   SO the final version would be:
   List all items in the main category
   Then list all the items in the subcategories under their headings.

   Would LOVE if I could get help here.

   cool... so what you want to do is this?:

   MAIN CAT
   SUB CAT
   SUB CAT

   MAIN CAT
   SUB CAT
   SUB CAT

   etc....

    Hmm, the link example is pretty close, but if you take a look, Rehab forearm 1 is a subcategory item under REHAB FOREARM. So it shouldn't be listing at the top under the main category as well. So I need something like:

    MAIN CATEGORY HEADING
    list main category items only
    SUB CATEGORY HEADING
    list sub category items only
    SUB CATEGORY HEADING
    list sub category items only
    :)

    it looks as if you need to break this into several loops;

    first: top category posts loop only (using 'category__in' parameter in the query; possibly collect the post id for 'do-not-dup' purpose;

    second:
    get all subcategories;
    foreach loop through each of them;
    post loop with the 'category__in' and 'post__not_in' parameters in the query; again, possibly collect the post id for 'do-not-dup' purpose;
    endforeach;

    can you paste the full code of your template as a starting point for any suggestions?

    Sure thing alchymyth, thank you. I used the code you posted earlier, i think you're probably right on the repeating loops. Here's the full template :)

    wp_list_categories will do the trick.

    Dear All,

    I am new to wordpress and I want to add a category and subcategories to my site. I am going to appearance and then to menu, but I don't know what to do after that, any advice?
