   Hi,
   I use this loop to show all the cats under the cat id:2

   <?php query_posts('cat=2&orderby=rand&showposts=8'); ?>
   <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
   ...

   and i'd like to do another loop to show only the childe cats of the parent id:2, how can i do it?

   Thanks in advance

   use the post_parent argument. See the template tag, query_posts(), for other arguments you can use.

   Oops, post_parent is for pages.

   Try:
   

   <?php
   //get all posts for children of category $cata
   $cata = 6;
   $taxonomy = 'category';
   $cata_children = get_term_children( $cata, $taxonomy );
   
   $args=array(
     'category__in' => $cata_children,
     'post_status' => 'publish',
     'posts_per_page' => -1,
     'caller_get_posts'=> 1
   );
   $my_query = null;
   $my_query = new WP_Query($args);
   if( $my_query->have_posts() ) {
     echo 'List of Posts belonging to Category A children';
     while ($my_query->have_posts()) : $my_query->the_post(); ?>
       <p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>
       <?php
     endwhile;
   }
   wp_reset_query();  // Restore global post data stomped by the_post().
   ?>

   It work, thank you.

   i'd like to share my code if any one wanna it,
   

   <ul class="gallery-more">
   	<?php
   	//get all posts for children of category $cata
   	$cata = 3;
   	$taxonomy = 'category';
   	$cata_children = get_term_children( $cata, $taxonomy );
   
   	$args=array(
   	  'category__in' => $cata_children,
   	  'post_status' => 'publish',
   	  'posts_per_page' => -1,
   	  'showposts'=>8,
   	  'orderby'=>rand,
   	  'caller_get_posts'=> 1
   	);
   	$my_query = null;
   	$my_query = new WP_Query($args);
   	if( $my_query->have_posts() ) {
   	  echo 'List of Posts belonging to This Category';
   	  while ($my_query->have_posts()) : $my_query->the_post(); ?>
   
   				<?php // call the custom field key "exemple_image1" //
   				$var_img01 = get_post_meta($post->ID, "exemple_image1", TRUE);?>	  
   
   				<li>
   					<?php // Capture the custom field "image 1" //
   							if ( $var_img01 ) { ?>
   								<a title="Read more about : <?php the_title(); ?>" href="<?php the_permalink() ?>">
   									<img alt="<?php the_title(); ?>" src="<?php echo $var_img01; ?>"/>
   								</a>
   					<?php } else { ?>
   									<img src="<?php bloginfo('stylesheet_directory'); ?>/img/no-img.jpg" title="No image" width="100" height="100"/>
   					<?php } ?>
   						<div class="bg"/>
   
   				</li>
   	<?php endwhile; }
   		wp_reset_query();  // Restore global post data stomped by the_post().
   	?>
   </ul>

   The idea her, is to create a personal gallery of a products.

   Enjoy.

   Probably better to change

   'posts_per_page' => -1,
   'showposts'=>8,

   to
   

   'posts_per_page' => 8,

   How can this be modified to Show posts belonging to children categories of the current category of the single post that is currently showing?

   Thanks
