   I've been trying to make a sidebar nav that would only display post titles from the current category you are viewing and highlight the current active post (using CSS).

   I have two code snippets and would need to merge them somehow. I don't know PHP well enough to do this myself.

   Show Posts (all categories), and highlight current one using CSS:
   

   <ul class="sidebar-ul">
   <?php
   $IDOutsideLoop = $post->ID;
   global $post;
   
   $myposts = get_posts('showposts=5');
   foreach($myposts as $post) :
   ?>
   
   <li <?php if(is_single() && $IDOutsideLoop == $post->ID) {echo " class=\"test\"";}?>><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
   
   <?php endforeach; ?>
   
   </ul>

   Show Posts By Current Category only:
   

   <ul>
   
   <?php while(have_posts()) : the_post(); ?>
   
   <?php foreach((get_the_category()) as $category)
   { $my_query = new WP_Query('category_name=' . $category->category_nicename . '&orderby=title&order=asc&showposts=100');} ?> 
   
   <?php while ($my_query->have_posts()) : $my_query->the_post(); ?>
   
   <li><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></li>
   
   <?php endwhile; ?>
   
   <?php break; endwhile; ?>
   </ul>

   This worked for me:

   <ul>
   <?php
   $IDOutsideLoop = $post->ID;
   while( have_posts() ) {
   	the_post();
   	foreach( ( get_the_category() ) as $category )
   		$my_query = new WP_Query('category_name=' . $category->category_nicename . '&orderby=title&order=asc&showposts=100');
   	if( $my_query ) {
   		while ( $my_query->have_posts() ) {
   			$my_query->the_post(); ?>
   			<li<?php print ( is_single() && $IDOutsideLoop == $post->ID ) ? ' class="test"' : ''; ?>>
   				<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a>
   			</li>
   <?php
   		}
   	}
   }
   ?>
   </ul>

   Not sure what it would do if there were more than one category though?

   Thanks, but I'm getting an error, my code viewer is saying it's something to do with this line:

   <?php print ( is_single() && $IDOutsideLoop == $post->ID ) ? ' class="test"' : ''; ?>

   thanks!

   Hi
   I have tried using your code on my website and I have a problem ...
   I am using this code in my sidebar to list all the categories as a menu
   <ul id="leftnav">
   <?php wp_list_categories('orderby=name&title_li=&exclude=1,25'); ?>

   which works great ... I put your code into another sidebar so when I click on a link on the menu on the front page it displays the posts and the sidebar menu changes to show the post titles for the current category (using your code)
   The problem I am having is when I first click on the menu bar it is displaying all the posts and the left menu bar shows duplicate post titles ... if I then click on 1 of the links in the sidebar the duplicated post titles disappear and it works as it should ...

   How can I stop the duplicating of the post titles please?

   Thanks for your help
   PS hope you can understand the problem ...

   I used this code to do show all the posts in a category in the sidebar, and ran into the same problem that sirhank did: it repeated the names of posts over and over.

   Can I please get the fix that allows it to show each post in that category only once? Also, if there's a hack that both 1) shows each post name only once and 2) excludes the current post form the list, I'd love to know that one.

   I ain't no PHP wiz, but I got something to work that won't duplicate the titles:

   <?php
   foreach( ( get_the_category() ) as $category ) {
   $the_query = new WP_Query('category_name=' . $category->category_nicename . '&showposts=5');
   while ($the_query->have_posts()) : $the_query->the_post();
   ?>
   			<li>
   				<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a>
   			</li>
   <?php endwhile; ?>
   <?php
   }
   ?>
