I have this PHP code that shows a related posts element created using advanced custom fields plugin. I want to create a shortcode inside functions.php with the code and then use the shortcode in a text element of a page builder. Would someone kindly assist me with the modified code to put inside functions.php? Thanks

<?php
$posts = get_field('related_posts', false, false);
$loop = new WP_Query(array('post_type' => 'post', 'posts_per_page' => 3, 'post__in' => $posts, 'post_status' => 'publish', 'orderby' => 'post__in', 'order' => 'ASC' ));

if($loop->have_posts()) { ?>
    <div class="rel-posts">

    <?php while ($loop->have_posts()) : $loop->the_post(); ?>

        <div class="related-post">
            <a href="<?php the_permalink(); ?>"><?php the_post_thumbnail('td_218x150'); ?></a>
            <h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
        </div>

    <?php endwhile; ?>

</div>
<?php } wp_reset_query(); ?>

If your code works fine then do this in function.php

    <?php
    add_shortcode( 'custom_name', 'footag_func' );
    function footag_func( $atts ) {
    $html= '';
    $posts = get_field('related_posts', false, false);
    $loop = new WP_Query(array('post_type' => 'post', 'posts_per_page' => 3, 'post__in' => $posts, 'post_status' => 'publish', 'orderby' => 'post__in', 'order' => 'ASC' ));

    if($loop->have_posts()) { 
       $html .= '<div class="rel-posts">';

        while ($loop->have_posts()) : $loop->the_post(); 

           $html .= '<div class="related-post">';
            $html .='<a href="'.the_permalink().'">'.the_post_thumbnail('td_218x150').'</a>';
              $html .=  '<h3><a href="'.the_permalink().'">'.the_title().'</a></h3>';
           $html .=  '</div>';

        endwhile; 

   $html .= '</div>';
   } wp_reset_query(); 
    }
    return $html;
    ?> 

your shortcode [custom_name]

  • Thank you for this. I have seen that the related posts appear at the top of the page created with page builder rather than at the location where I placed the shortcode (at the bottom). Is that a normal behaviour? – Mato Dec 29 '18 at 15:49
  • Shortcodes must return their contents, not directly print or echo. – Milo Dec 29 '18 at 16:27
  • @Milo I am a php newbie. How do I make the code above as you specified? Or could you kindly provide the edited code as per your suggestion? – Mato Dec 30 '18 at 8:12
  • @Mato edited the code – Techno Deviser Dec 31 '18 at 6:49
