Question

Okay, so I have a WordPress template that I created that only displays posts that have the “workout” category associated with it. Within the loop that displays those, I want the categories of the specific post to be listed.

I was thinking something like this would work:

$id = get_the_ID();
$cats = wp_get_post_categories($id);

But then I do not know how to echo this out on to the screen.
Anyone have any idea how I can display the categories of each post within the loop? All of the articles I have looked at have only showed how to display all categories, not display the categories associated with a specific post.

Here is the loop I have:

<div class="query">
<b><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></b>
    <?php 
        $id = get_the_ID();
        $cats = wp_get_post_categories($id);
    ?>
</div>
<?php endwhile; ?>

Answer 1

Get the category objects:

$cats = get_the_category($id);

Just echo the name:

echo $cats[0]->name;

If you want to output a link, use this:

<a href="<?php echo get_category_link($cats[0]->cat_ID); ?>">
    <?php echo $cats[0]->name; ?>
</a>

Note: instead of wp_get_post_categories($id), you could just use get_the_category().

Update: if you want to display all the categories, just loop through them:

<?php foreach ( $cats as $cat ): ?>

    <a href="<?php echo get_category_link($cat->cat_ID); ?>">
        <?php echo $cat->name; ?>
    </a>

<?php endforeach; ?>
