I figured it out in the end from a combination of trial and error from a few different sources. Here is what I came up with in the end:
<?php $key_1_value = get_post_meta( get_the_ID(), '_ct_datepicker_58d1755e1a654', true ); if ( ! empty( $key_1_value ) ) { echo '<div class="mtt date-added">' . '<span>' . 'Date Added:' . '</span>' . $key_1_value . '</div>'; } ?>
This is just one custom post ID, I have several each requiring their own div containers and css etc. but the has done the job. I can now output the custom post value into a div container of my creation, and if it is empty it just won’t show at all.
Thank you to everyone who did steer me down the right route.
