If a WordPress page post content is empty, you might want to dynamically show or hide some other divs or design aspects of your website. Here is how you do it.
<?php $content = get_post()->post_content; if(empty($content)):?> POST CONTENT IS EMPTY <?php else:?> <?php if (have_posts()) : while (have_posts()) : the_post(); ?> <?php the_content(); ?> <?php endwhile; else: endif; ?> <?php endif;?>
