   Hi,

   I am trying to include a custom field value without displaying the key. Previously I would have used a shortcode plugin to do this, but echoing a do_shortcore seems a little hacky to me. Is there a better way?

   I'm not sure I really understand this function.

   Lets say I only have one key called descriptions, I think the php should look like this:
   <?php $key_description_value = get_post_meta($post->ID, 'Description', true); echo $key_description_value;?>
   or
   <?php $key_description_value = get_post_meta($post->ID=$post_id, 'Description', true); echo $key_description_value;?>

   but I get nothing...

   <?php $key_description_value = get_post_meta($post->ID, 'Description', true); echo $key_description_value;?>

   Will work, providing it's in the loop (so it has a post ID) and the custom field exists for that post.

   You could narrow down the problem by IF/ELSE'ing the field value check. You could also check the post ID is valid.
   

   <?php if(!$post->ID) echo 'post ID doesn\'t exist'; ?>
   <?php $key_description_value = get_post_meta($post->ID, 'Description', true); ?>
   <?php if(!$key_description_value) { echo 'nothing found'; } else { echo $key_description_value; }?>
