[resolved] Show a post list of current category (11 posts)

    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?
