I've 3 custom fields on the page, they're dailytip_1, dailytip_2 and dailytip_3.

So I wish to show only one tip from the 3 tips at random around the page. Things I can perform? Thanks!

<?php $dailytip_1 = get_post_meta($post->ID, 'dailytip_1', true); ?>

<?php if ($dailytip_1 !== '') { ?>
    <p><?php echo get_post_meta($post->ID, 'dailytip_1', true); ?></p>
<?php } ?>

Does the next help?

<?php
    $random_dailytip = 'dailytip_' . rand( 0, 2 );
    $dailytip = get_post_meta($post->ID, $random_dailytip, true);

?>

<?php if ($dailytip !== '') { ?>
    <p><?php echo get_post_meta($post->ID, $random_dailytip, true); ?></p>
<?php } ?>

As you can tell, $random_dailytip will get the values dailytip_0, dailytip_1 or dailytip_2 at random.
