    	<?php endwhile; // end of the fields loop ?>
    
  </div>
  
  <?php endwhile; // end of the groups loop ?>
  
</div>
<?php else : // content to show if no record is found ?>

  <?php $error_message = Participants_Db::plugin_setting( 'no_record_error_message', '' );
  
  if ( ! empty( $error_message ) ) : ?>

    <p class="alert alert-error"><?php echo $error_message ?></p>
    
  <?php endif ?>
    
<?php endif ?>

This demonstrates the use of a custom template for showing a value from the record data as a public field.

The template should be called with a shortcode like this: [pdb_single template=show-timestamp]
