Hi, I’m trying to create a random repeater using this method, but the output is blank. Can anyone spot where I’m going wrong?

<?php 

	$rows = get_field('homepage_images' ); // get all the rows
	$rand_row = $rows[ array_rand( $rows ) ]; // get a random row
	$rand_row_image = $rand_row['image_set']; // get the sub field value 

	$image = wp_get_attachment_image_src( $rand_row_image, 'full' );
	// url = $image[0];
	// width = $image[1];
	// height = $image[2];
?>

   <header class="hero" style="background-image: url(<?php echo $image[0]; ?>)">

   </header>

you’re using array_rand() wrong

$rand_row = array_rand($rows, 1); // get a random row

Thanks I got it sorted – I was using URL as the image type. Changed it to ID and it worked.
