random custom field wordpress

Question

I have 3 custom fields on a page, they are dailytip_1, dailytip_2 and dailytip_3.

So I want to show only 1 tip of the 3 tips randomly on the page. What I 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 } ?>

Answer 1

Does the 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 you can see, $random_dailytip gets the values dailytip_0, dailytip_1 or dailytip_2 randomly.
