Thread: How do you display a specific custom field?

How do you display a specific custom field?

I know in single-listing this gets all the custom fields:

<div class="listing-fields">
<?php the_listing_fields(); ?>
</div>

How can we just get the contents of one field?

I have tried this but it did not work:
<?php get_post_meta( $post->ID, 'listing-custom-field-youtube', true ) ?>

Figuring out how to get an individual custom field is the first thing I need to know how to do.

The next I need to figure out how to turn it into a clickable link, or even better, be able to have it be a clickable image like the facebook icon.

I already have custom fields containing the URLs for; youtube, linkedin, google+, etc. Just need to figure out how to make them function like the facebook image link.

Thanks in advance.
