   hi! I'm a dummy user with wordpress.

   In a sidebar, I'm trying to insert a code that shows a list of the posts of a current category (the category of the post where I am).

   Now the code is:

   <?php if(is_category() || is_single()){
    global $post;
    foreach(get_the_category() as $category)
    {
     $current = $category->cat_ID;
     $current_name = $category->cat_name;
    }
   }
   echo $current_name . " has id ".$current;
   $myposts = get_posts('numberposts=50&category='.$current);
   foreach($myposts as $post) : ?>
          <li>
            <a href="<?php the_permalink(); ?>">
            <?php the_title(); ?></a>
          </li>
   <?php endforeach; ?>

   Actually it doeasn't work correctly, because it show me more than the post really in the current category. Why?
   I have to exclude parent and child category?
   How can I do?

   Can You help me please?
   thanks, Marco

   Change:
   

   foreach($myposts as $post) : ?>

   to
   

   foreach($myposts as $post) :
   setup_postdata($post);?>

   MichaelH, thanks a lot for your reply, but it doesn't work correctly yet.
   How can I exclude parent and child categories of every current category?

   What do you think?

   Actually I was ignoring
   

   I have to exclude parent and child category?

   because it didn't make sense to me, so maybe someone else understands and can help you.

   I will add this bit of code and info from notes:

   In a sidebar, if single post, for the first category of that post, display 5 posts in that category, excluding the single post.

   <?php
   if ( is_single() ) {
     $cats = wp_get_post_categories($post->ID);
       if ($cats) {
       $first_cat = $cats[0];
       $args=array(
         'cat' => $first_cat, //cat__not_in wouldn't work
         'post__not_in' => array($post->ID),
         'showposts'=>5,
         'caller_get_posts'=>1
       );
       $my_query = new WP_Query($args);
       if( $my_query->have_posts() ) {
         echo 'Related Posts';
         while ($my_query->have_posts()) : $my_query->the_post(); ?>
           <p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>
          <?php
         endwhile;
       } //if ($my_query)
     } //if ($cats)
     wp_reset_query();  // Restore global post data stomped by the_post().
   } //if (is_single())
   ?>

   dear Michael, sorry for my english.
   Have you got a moment for me, again?

   My first problem, I think, is that the structure of the categories is made of parents and many children.

   Infact the code, in the sidebar, works correctly when the current post is the last children category , but doesn't work when the post is in a parent category with some children.
   And then it shows me the posts of that category and the posts of the category child. Too many posts.

   And then my question is:
   is there a way to exclude the children by the current category?

   thanks in advance, again!
   Marco

   Michael, It's Incredible! it's working correctly now!
   I matched several solutions I found in this forum and now I don't know why it works now!
   I found one of your post in a forum, and... the mistery:

   <?php
   	global $post;
   	if(is_category() || is_single()){
   	foreach(get_the_category() as $category)
   	{
   	$current = $category->cat_ID;
   	$current_name = $category->cat_name;
   
   	//query_posts("cat=". $current);
   
   	$myposts = get_posts(array('category__in' => array($current)));
   
   	//$myposts = get_posts('numberposts=50&category='.$current); 
   
   	//query_posts(array('category__in' => array(11)));
   		}
   	}
   
   	foreach($myposts as $post) :
   	setup_postdata($post); 
   
   	?>
   	<li>
   	<a href="<?php the_permalink(); ?>">
   	<?php the_title(); ?></a>
   	</li>
   
   	<?php endforeach; ?>

   thanks a lot for your care!

    I'm using the code directly above me from ruzzino.

    as seen here http://www.bpdfriends.com/section/blog/

    however for some reason its showing a post there /blog/ is a parent category with no post in it... but its still choosing to display a post from the http://www.bpdfriends.com/section/blog/bipolar-blog/

    both of the following work perfect (they are child categories)
    http://www.bpdfriends.com/section/blog/bipolar-blog/
    http://www.bpdfriends.com/section/blog/bpd-blog/

    any way of altering the code to now show the post

    This code MichaelH posted works great for me;
    

    $cats = wp_get_post_categories($post->ID);
        if ($cats) {
        $first_cat = $cats[0];
        $args=array(
          'cat' => $first_cat, //cat__not_in wouldn't work
          'post__not_in' => array($post->ID),
          'showposts'=>5,
          'caller_get_posts'=>1
        );
        $my_query = new WP_Query($args);
        if( $my_query->have_posts() ) {
          echo 'Related Posts';
          while ($my_query->have_posts()) : $my_query->the_post(); ?>

    but how can you display the 5 previous posts to the current post date within the same category?
