   Hello everyone.

   Before I start, I'm still learning WordPress and PHP so please be gentle :)

   I thought I'd try to get my head around custom taxonomies. I'm using the plugin Custom Post Types UI to create a post type of 'Directory Listing', a custom taxonomy of Directory Category, some terms inside this category, therefore looking like this:

   Directory Listing (custom post type)
   > Directory Category (custom taxonomy)
   > Children and Family (term)
   > Entertainment (term)
   > Motoring (term)
   > Pets (term)

   I have the following page template:
   loop-page-directory.php (also with a page-directory.php) the former containing only the following code:

   <?php wp_tag_cloud( array( 'taxonomy' => 'directory-category', 'format'=>'list', 'smallest' => 16, 'largest' => 16, 'unit' => 'px' ) ); ?>

   This lists all the terms above Children, Entertainment, Motoring, Pets; I can click each item and it takes me to the business listings I've added with that term. This is housed on a page template called:
   loop-taxonomy-directory-category.php (I've created a corresponding taxonomy-directory-category.php). The former contains the following code:

   <!-- Business and Organisation Listings Page -->
   
   <?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>
   
   <div class="entry-content">
   <!-- Custom Fields -->
   	<div id="wrapper-dirlist">
   	<div class="dirlist-brand"><?php echo get_post_meta($post->ID, 'bizbrand', true); ?></div>
       <div class="dirlist-content">
               <div class="dirlist-title"><?php the_title(); ?></div>
               <div class="dirlist-address"><?php echo get_post_meta($post->ID, 'dirlist-address', true); ?></div>
               <div class="dirlist-description"><?php the_content(); ?></div>
               <div class="dirlist-contactinfo">
               <li><?php echo get_post_meta($post->ID, 'dirlist-phone', true); ?></li>
               <li><?php echo get_post_meta($post->ID, 'dirlist-email', true); ?></li>
               <li><?php echo get_post_meta($post->ID, 'dirlist-website', true); ?></li>
               <li><?php echo get_post_meta($post->ID, 'dirlist-document', true); ?></li>
               <li><?php echo get_post_meta($post->ID, 'dirlist-voucher', true); ?></li>
               </div>
   	</div>
       </div><!-- .entry-content -->
   </div>
   <?php endwhile; // end of the loop. ?>

   This lists the items perfectly fine and they are styled okay with CSS.

   My problem and difficulty arises when I try to order the listed items randomly, so that my most recently added listing is not on top, but that all listings have a chance, through random ordering, to be on top.

   I've tried loads of things yesterday (this was my brick wall) including various pieces of code with 'orderby' => 'rand' in them, but I'm clearly not understanding this.

   Any help and advice is welcome.

   Thank you.

   Gavin.

   try:

   <?php global $query_string;
   query_posts( $query_string . "&orderby=rand" );
   
   <?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>

   Hi alchymyth

   Thank you very much, these appears to have worked. I should have got in touch sooner (and maybe got to bed earlier :))

   As a matter of interest, is the way I'm approaching this okay? It works, but if there is a better way to do it, what suggestions do you have?

   Thank you again.

   I had both the codex references you posted in my bookmarks and had read through them several times. I think the issue for me was fully understanding what had been written, and where to put the final piece of code.

   the codex is like an encyclopedia - all the words are there - but not the poem.

   'code is poetry'
