I am familiar with the repeater function, but have not used the repeater random function and try to get from another page. Here is the code I current have tried but not getting any results:
<?php
$other_page = 24;
$rows = get_field('clapper_images', $other_page); // get all the rows
$rand_row = $rows[ array_rand( $rows ) ]; // get the first row
$rand_row_image = $rand_row['people_clappers_images' ]; // get the sub field value
$image = wp_get_attachment_image_src( $rand_row_image, 'full' );
?>
<img src="<?php echo $image[0]; ?>" />
Any help will be great.
Hi @RE20
Your code looks great. Have you debugged it line by line?
You can debug your code like so:
<?php
echo '<pre>';
print_r( $rand_row );
echo '</pre>';
die; ?>
Do this for each line of code, and obviously change the $variable as you go through each line. This way you can see what data is in your variables.
You may find that there is a field name spelling mistake, or perhaps the return value of the image is an object, not an ID?
Thanks

Ok, thanks. I did some more research and came across this coding:
<?php while(the_repeater_field('clapper_images', '24')): ?>
<?php if($rand == $i): ?>
<?php the_sub_field('people_clappers_images', '24'); ?><?php endif; ?><?php $i++; ?>
<?php endwhile; ?>
It works, but only echos out one image and the same image every time. Any ideas how to get it to echo out a random image each time.
got it figure out
<?php $rand = rand(0,4); $i = 0; ?>
<?php while(the_repeater_field('clapper_images', '24')): ?>
<?php if($rand == $i): ?>
<?php the_sub_field('people_clappers_images', '24'); ?>
<?php endif; ?><?php $i++; ?>
<?php endwhile; ?>
