Random repeater with image first()

[Roych]

Hello,

need your help   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

Any reason for using a repeater? (Image fields can hold multiple images anyway, and much easier to manipulate.) See

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): ?>
