I am using simple-tags for wordpress and want to show some related posts in my sidebar, when someone is viewing a single page, any ideas?

Fritz?.. you could insert a code like the one below. This one checks first if simpletags is running, if yes it will run on a single page only.
The simple tags function st_related_posts will give you back some posts tagged with one or more tags of the current post.
I set it to show 5 posts, no pages (if tagged) and the link is formatted with 'xformat' to show permalink, title and name of the related post.
Try it!
```
<?php if (class_exists('SimpleTags')) : ?>
<?php if ( is_single() ) { ?>
<h3>Related posts</h3>
<?php st_related_posts('number=5&title=&include_page=false&xformat=<a href="%permalink%" rel="bookmark" title="%title%">%title%</a>'); ?>
<?php } ?>
<?php endif; ?>
```

finally I realized many errors with this code. I put just for debugging this in the header.php of my theme:

<?php error_reporting(E_ALL); ini_set('display_errors', '1'); ?>

beside many other php errors the code with st_related_posts shows errors like:

Notice: Undefined property: stdClass::$terms_id in /wp-content/plugins/simple-tags/inc/client.php on line 715
Notice: Undefined property: stdClass::$post_excerpt in /wp-content/plugins/simple-tags/inc/client.php on line 716
Notice: Undefined property: stdClass::$post_content in /wp-content/plugins/simple-tags/inc/client.php on line 716
Notice: Undefined property: stdClass::$post_password in /wp-content/plugins/simple-tags/inc/client.php on line 716
etc ...

Now I generate related posts with this code, which displays almost the same rsults:

<?php
// list 5 post titles related to first tag on current post in list style as st_related_posts
$tags = wp_get_post_tags($post->ID);
if ($tags) {
  echo '<ul class="st-related-posts">';
  $first_tag = $tags[0]->term_id;
  $args=array(
    'tag__in' => array($first_tag),
    'post__not_in' => array($post->ID),
    'showposts'=>5,
    'caller_get_posts'=>1
   );
  $my_query = new WP_Query($args);
  if( $my_query->have_posts() ) {
    while ($my_query->have_posts()) : $my_query->the_post(); ?>
      <li><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></li>
      <?php
    endwhile;
  }
  echo '</ul>';
  }
?>

code above just replaces the single line

<?php st_related_posts('number=5&title=&include_page=false&xformat=<a href="%permalink%" rel="bookmark" title="%title%">%title%</a>'); ?>
