query_posts in sidebar for post category

I use the Imbalance WordPress Theme. When viewing single posts you will get a list of post-thumbnails for recent posts in the sidebar. The query that calls them (in sidebar-featured.php) looks like this:

query_posts(“showposts=2&offset=1”);

This displays the two most recent posts, except the very most recent one, in the sidebar list.

Is it possible to display a given number of, or all, posts only from the same category as the post I am viewing? And is it in that list possible to exclude the post I am viewing?

What set of commands do I need to achive this?

try to change your line into:
```
global $post;
$args = array(
  'posts_per_page' => 5, //limit the post numbers,or use -1 for all
  'post__not_in' => array($post->ID), //exclude current post
  'category__in' =>  wp_get_post_categories( $post->ID ) //use categories of current post
);
query_posts( $args );
```

http://codex.wordpress.org/Function_Reference/wp_get_post_categories

and add a wp_reset_query(); after the endif; or endwhile; of this loop.

generally, it would be better if you could use WP_Query() for a secondary loop such as your example.

Wow! Thanks!! That worked great 🙂

Is it possible to display posts from a certain category AND with a certain tag? It doesn’t seem to work expanding your code like this:
```
global $post;
$args = array(
  'posts_per_page' => 5, //limit the post numbers,or use -1 for all
  'post__not_in' => array($post->ID), //exclude current post
  'category__in' =>  wp_get_post_categories( $post->ID ), //use categories of current post
  'tag__in' =>  wp_get_post_tags( $post->ID ) //use tags of current post?
);
query_posts( $args );
```

slight complication:

http://codex.wordpress.org/Function_Reference/wp_get_post_tags

as you can see, the default output of this function is different from the one of ‘wp-get-post-categories()

needs to be corrected by the proper use of the $args array:
http://codex.wordpress.org/Function_Reference/wp_get_object_terms#Argument_Options

i.e.:

'tag__in' => wp_get_post_tags( $post->ID, array( 'fields' => 'ids') ) //use tags of current post

the result is a ‘OR’ -> the related posts will be from any of the categories or any of the tags.
