random custom field wordpress -

-

i have 3 custom fields on page, dailytip_1, dailytip_2 , dailytip_3.

so want show 1 tip of 3 tips randomly on page. can do? 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 following 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 can see, $random_dailytip gets values dailytip_0, dailytip_1 or dailytip_2 randomly.
