Custom Fields to Add Links

    Hi, Right now I want to display 3 links on my article using custom fields. Here is what I did:

    <div>
<h3>Related Top Searched</h3>
<ul>
<li><?php
{ $gsubtitle = get_post_meta
($post->ID, 'gsubtitle', $single = true);
if($gsubtitle !== '') echo $gsubtitle;} ?></li>

<li><?php
{ $bsubtitle = get_post_meta
($post->ID, 'bsubtitle', $single = true);
elseif($bsubtitle !== '') echo $bsubtitle;} ?></li>

<li><?php
{ $ysubtitle = get_post_meta
($post->ID, 'ysubtitle', $single = true);
if($ysubtitle !== '') echo $ysubtitle;} ?></li>
</ul>
</div>

    It serves the purpose but the only problem is that it shows even on posts that dont have the value. Like:

    Related Top Searched
> (blank)
> (blank)
> (blank)

    What I want to do?
    I want to show this 3 custom fields only if they have a value. I know contidional tags can do it but I dont know how to apply. Also please help me make the code simple. Thanks a lot.

    try and restructure your code:

    <?php
$gsubtitle = get_post_meta($post->ID, 'gsubtitle', $single = true);
$bsubtitle = get_post_meta($post->ID, 'bsubtitle', $single = true);
$ysubtitle = get_post_meta($post->ID, 'ysubtitle', $single = true);

if( $gsubtitle || $bsubtitle || $ysubtitle ) : ?>

<div>
<h3>Related Top Searched</h3>
<ul>
<?php
if($gsubtitle !== '') echo '<li>' . $gsubtitle .'</li>';
if($bsubtitle !== '') echo '<li>' . $bsubtitle .'</li>';
if($ysubtitle !== '') echo '<li>' . $ysubtitle .'</li>';
?>
</ul>
</div>
<?php endif; ?>

    (this is assuming that you want all filled in custom fields to show)
    if the elseif on the $bsubtitle is important, the re-integrate it into the second line of the ifs.

    alchymyth, one more thing, how do I make the links to open in new window?

    On another website I use it but only one custom field. But this time I want the result link to be like:

    <a target="_blank" href="http://www.website.com/">View Source</a>

    Where “http://www.website.com&#8221; is the value of the custom field.
