Special Fields Turned on or off with Conditional StatementsHelpful Member!

I've used some special fields which I would like to call up only if they have a record against them. At the moment all I have is the echo for them - I'm unsure how to wrap them in a conditional statement i.e. if the record exists then echo it, if not then don't show anything. Here is the code currently:

CODE

    

<div class="logbookpositionl">
      <?php the_time('d F, Y') ?><br><br>
      <?php $key="leg"; $value =get_post_meta($post->ID, $key, true); echo "".$value;?><br><br>      
      <?php $key="lat"; $value =get_post_meta($post->ID, $key, true); echo "".$value;?><br>
      <?php $key="lon"; $value =get_post_meta($post->ID, $key, true); echo "".$value;?>
    </div>
<div class="logbookpositionr">
     <?php $key="vessel"; $value =get_post_meta($post->ID, $key, true); echo "Vessel: ".$value;?><br><br>
      <?php $key="distance"; $value =get_post_meta($post->ID, $key, true); echo $value." nautical miles";?> <br><br>
      <?php $key="weather"; $value =get_post_meta($post->ID, $key, true); echo "Weather: ".$value;?>       
    </div>

You can see in the second section I have included some descriptive text. At the moment this is being echoed irrespective of the fact there isn't a record in there.

I'm pretty new to PHP so any help would be gratefully received.

Thanks in advance.

You should be able to prefix your echo statements with an if statement, something like this:

CODE

<?php
    $key = "distance";
    $value = get_post_meta($post->ID, $key, true);
    if ($value != "") echo $value . " nautical miles";
?>

Hope this helps,
Dan
