Category-specific sidebar

    This will hopefully be simple — in the sidebar of each single-post page, I want a box which says, “More from this category” and lists the last 5 relevant headlines from whatever category you’re in. I realize I can specify an ID and do it like this:

    <?php if ( is_single() || in_category('3') ) : ?>
<li>
<h2>More in this Section</h2>
<ul class="bullets">
<?php
$posts = get_posts('numberposts=10&category=3');
foreach($posts as $post) :
?>
<li>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
</li>
<?php endforeach; ?>
</ul>
</li>
<?php endif ; ?>

    But, I don’t want to manually type in the ID# for each. How can I use the code above and make it more dynamic?

  • <?php
if ( is_single() ) :
global $post;
$category = get_the_category();
?>
<li><h2>More in this Section</h2>
<ul class="bullets">
<?php
$posts = get_posts('numberposts=10&category='. $category[0]->term_id);
foreach($posts as $post) :
?>
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endforeach; ?>
</ul>
</li>
<?php endif ; ?>

    This collects all categories a post is assigned to and passes the category ID# of the first category ($category[0]->term_id) as the value for the get_posts() ‘category’ parameter.

    (Using WordPress <= 2.2.x, change $category[0]->term_id
    to $category[0]->cat_ID)

    Also, for multiple categories (because someone *will* ask):

    <?php
if ( is_single() ) :
global $post;
$categories = get_the_category();
foreach ($categories as $category) :
?>
<li><h2>More in <?php echo $category->name; ?></h2>
<ul class="bullets">
<?php
$posts = get_posts('numberposts=5&category='. $category->term_id);
foreach($posts as $post) :
?>
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endforeach; ?>
</ul>
</li>
<?php endforeach; endif ; ?>

    Brilliant, Kafkaesqui, thank you! I will test that code tonight.
