    Hi

    The following code inserts a <div class=”row thirds”> div every 3 posts. But if there are 3 posts, an empty <div class=”row thirds”> is added. How do I prevent the empty div?

    Thanks

    <div class="row thirds">
<?php
// Find connected pages
$connected = new WP_Query( array(
  'connected_type' => '2-col-module_to_pages',
  'connected_items' => get_queried_object(),
  'nopaging' => true,
) );

// Display connected pages
if ($connected->have_posts() ) : while ($connected->have_posts()) : $connected->the_post(); ?>

                <h2><?php the_title();?></h2>

<?php $counter++;
// add row div every 3 posts
      if ($counter % 3 == 0) {
         echo '</div><div class="row thirds">';
         }
        endwhile;  wp_reset_postdata(); endif; ?>
</div>

    Add another conditional statement to check that counter is not equal to the length of posts.

    Thanks for your reply, Andrew. Could you give an example please?

    Does $counter hold all of the posts? If so:

    if ($counter % 3 == 0 && $counter !== count($connected) ) {

    So now I have this

    But it doesn’t work?

    <?php $counter++;
      if ($counter % 3 == 0) {
         echo '</div><div class="row thirds">';
         }
      if ($counter % 3 == 0 && $counter !== count($counter) ) {
        echo '';
      }
        endwhile;  wp_reset_postdata(); endif; ?>

    Am I doing something wrong?

    Sorry I meant, does $connected hold all of the posts?

    So how does that look?

    If you var_dump $connected what do you get?

    Sorry, I don’t know what you mean. I’m fairly new to php. Can you give a bit more detail please?
