Sometimes you would want to output content based on WordPress meta fields – and use conditions (statements) based on whether or not the meta fields have data, etc. In this example, we are using a meta field with the name: “youtube-video-id” and value: “abcd1234”.

Instructions
Add this code to your single.php file (or similar).

<?php
   if (get_post_meta($post->ID, 'youtube-video-id', true)) : ?>
      <p><?php echo get_post_meta($post->ID, 'youtube-video-id', true) ?></p>
   <?php endif;
?>
