    Hello all.

    I am working on a project for my company building a word press template. On the single.php page, they would like at the end of the post a section that would basically display the next post in line, so a link that says “Read what’s next” followed by the posts categories, the title and the excerpt. I have every working, but the categories, I have tried and searched for hours to find out how to do this, is it possible? my code below:

    <div class="entrynext">
      <div class="whats-next">
        <?php next_post_link( '%link', "Read What's Next »"); ?>
        </a></div>

        <?php
$next_post = get_next_post();
if (!empty( $next_post )): ?>

      <div class="categoryHeader">

	Categories should display here

      </div>
      <h3> <a href="<?php echo get_permalink( $next_post->ID ); ?>"><?php echo $next_post->post_title; ?></a>
      </h3>
      <div class="entry-content">
        <div class="entry-excerpt">
          <h4>
           <?php echo $next_post->post_excerpt; ?>
          </h4>
        </div>

        <!-- .entry-excerpt --> 

      </div>
      <?php endif; ?>
      <!-- .entry-content -->

    Thanks 🙂

    use below code

    <div class="categoryHeader">
    <?php
        $nextpostid = $next_post->ID;
        echo get_the_category_list(', ','',$nextpostid);
    ?>
</div>

    THANK YOU SO MUCH SWAYAM! This worked perfectly, another thing I just realized is that I need to exclude 3 categories, any hints on how to do that with this loop?

    Thanks again.

    so, you need to change the code, as now you need to exclude some categories, use code below

    <div class="categoryHeader">

<?php
$next_post = get_next_post();
$nextpostid = $next_post->ID;

$exclude_cats = array(6,7,8);

$allcats = get_the_category($nextpostid);

$numItems = count($allcats);
$i = 0;
$catstr = '';
foreach($allcats as $allcat){

	if(!in_array($allcat->term_id,$exclude_cats)){

		$catlink = get_category_link( $allcat->term_id );

		$catstr .= '<a href="'.$catlink.'">'.$allcat->name.'</a>, ';

	}

}

echo rtrim($catstr,', ');

?>
</div>

    the line where it says “$exclude_cats = array(6,7,8);”
    you need to pass id of categories you want to exlude from the list, let me know if it works.
