I use aside posts on my site http://inpursuitofhappiness.net to create the category "weekly challenge." I did some hacking to allow aside posts to have an excerpt, and display that excerpt on the home page.
This is the code I use to display the excerpt on the home page:
<?php $myposts = get_posts(array('numberposts' => 1, 'post_type' => 'weekly_challenge')); ?> <?php foreach( $myposts as $post ) : setup_postdata($post); ?> <div style="padding: 10px; font-family: Arial, Helvetica, Geneva, sans-serif;"> <?php the_excerpt(); ?> <div><a href="<?php echo get_home_url( 1, '/weekly-challenge/'); ?>" style="font-size: 10px;">More Weekly Challenges →</a></div> </div> <?php endforeach; ?>
I am using the PHP Code Widget plugin to paste that same code (minus the padding) into a sidebar widget to show up at http://inpursutifohappiness.net/blog, but it doesn't seem to be working.
On the blog homepage it displays the first 55 characters excerpt instead of the one I created. On individual blog posts, it pulls the excerpt for the most recent post.
