   Hi,

   I've been looking round the codex and Google, trying to find clues about how to achieve this, but I fear my PHP knowledge leaves a little to be desired.

   Basically my blog uses custom meta fields to display additional information on posts, however if these fields are left empty I want to hide the empty div that would otherwise contain the meta content and replace this with alternative content.

   I know this is probably grass roots 'if, else' stuff but I'm not so hot on the exact syntax, any help would be greatly appreciated.

   I currently call meta info using <?php echo get('analystnotes')?>

   Thanks, Rob

   If you are using Custom Fields and we are talking about displaying posts in a Loop this will try to find a custom field and then do something if the custom field exists or doesn't exist
   

   <?php
   $cf = get_post_meta($post->ID, 'analystnotes', true);
   if ($cf){
     //do your div thing here
   } else {
     //do nothing or whatever you need when no custom field was found
   }
   ?>

   Thanks Michael I really appreciate this, I now have the following code

   <?php
    $analystnotes = get_post_meta($post->ID, 'analystnotes', true);
    if ($analystnotes){ echo get ('analystnotes');
    } else {
    echo '<div class="analysisnone">BLANK</div>';
    }
    ?>

   This is largely working as I would like, but is there a way to wrap the get ('analystnotes')statement in a div, I know this is more a general PHP thing but haven't managed to figure it out.

   Thanks again

   Guessing your are asking something like what is used in the WordPress Default theme's wp-content/themes/default/index.php

   <div <?php post_class() ?> id="post-<?php the_ID(); ?>">

   Not sure that's quite what I'm after, I would just like to be able to apply a div class to the if statement

   All sorted, thanks, added an additional instance of the code to handle div classes.

   Really appreciated, thanks.
