Hello,

need your help :undecided:  I have repeater with only one image field and I would like it to be fetched randomly. It is used for a background images on a site.

my code:

<?php foreach($pages->get('/settings/')->BackgroundImages->getRandom() as $bck): ?>
	<?php $bckgimage = $bck->bgimage->first(); ?>
		<li><img data-fade='2000' src="<?php echo $bckgimage->url; ?>" alt="" /></li>
<?php endforeach; ?>

But it's not working and couldn't find the right answer on a forum ..

not sure how to do this

Thank you

R

You are only retrieving one BackgroundImages item with getRandom(). To get multiple items for your Wire Array you need to specify how many you want. https://processwire.com/api/ref/wire-array/get-random/

Alternatively to retrieve all BackgroundImages in random order you could try:

<?php foreach($pages->get('/settings/')->BackgroundImages->shuffle() as $bck): ?>
