Hi,
I’m trying to get my repeater field (on an options page) to randomly pick a row to display. The code I have shows a row successfully, but it’s the same row every time (row 2)
<?php $rand_max = count(get_field('the_block')); $i = 0; ?>
<?php while(the_repeater_field('the_block', 'option')): ?>
<?php if($rand_max == $i): ?>
<section id="theblock" style="background: url('<?php the_sub_field('block_background'); ?>');">
<div id="theblock-inner" class="container">
<div class="section-title civider">
<h2><?php the_sub_field('block_title'); ?></h2>
<h5 class="subtitle"><?php the_sub_field('block_subtitle'); ?></h5>
</div>
<a href="<?php the_sub_field('block_link_url'); ?>" class="btn"><?php the_sub_field('block_link_text'); ?></a>
</div>
</section>
<?php endif; ?>
<?php $i++; ?>
<?php endwhile; ?>
Hi @tommysvr
Your code does not contains any function to find a random number, only the amount of rows.. that is the issue.
Oh…haha sorry! Bit of a PHP novice. Would you mind pointing me in the right direction for that? Sorry if asking too much.
Appreciate your help!
Hi @tommysvr
Sorry mate, that parts up to you.
Please read to ACF docs. There are some code exmaples on the repeater field that will help you out
Please note: ACF is a developer tool and this support fourm is for providing help on bugs / ACF issues.
Thanks

No worries. Thanks for ACF – unbelievable plugin!
In case anyone stumbles upon this, I managed to get the code example to work with me…it was just adding ‘option’.
<?php $rows = get_field('the_block', 'option'); $row_count = count($rows); $i = rand(0, $row_count - 1); ?>
<section id="theblock" style="background: url('<?php echo $rows[$i]['block_background']; ?>');">
<div id="theblock-inner" class="container">
<div class="section-title civider">
<h2><?php echo $rows[$i]['block_title']; ?></h2>
<h5 class="subtitle"><?php echo $rows[$i]['block_subtitle']; ?></h5>
</div>
<a href="<?php echo $rows[$i]['block_link_url']; ?>" class="btn"><?php echo $rows[$i]['block_link_text']; ?></a>
</div>
</section>
