Displaying random values in options + repeater

Hi

First of all, I love the ACF plugins 🙂

I’ve created an options page in order to administer a custom banner I’ve created (title, image, link).

Now, I would like to have several banners rotating (randomly) instead of one. I’ve converted this field to a repeater field and I’ve added the other banners and it works as expected.

However, all banners are being displayed and I would only like to display one banner only (and show another random banner if the page is refreshed).

Is there a way to do this inside and options page + repeater field?

Thanks!

Hi @johanngonzalez

Please see this doc for random row example:

I’ve created an example Field Group with the same field names and the example won’t work. In my case, its a field group that’s a repeater and is being showed in the “options” page.

<?php

$rows = get_field(‘repeater_field_name’, ‘option’ ); // get all the rows
$rand_row = $rows[ array_rand( $rows ) ]; // get the first row
$rand_row_image = $rand_row[‘sub_field_name’ ]; // get the sub field value

$image = wp_get_attachment_image_src( $rand_row_image, ‘full’ );

?>
” />

Tried this, no luck.

Hi @johanngonzalez

The above code does not ouput anything to HTML.
Please echo any PHP value to HTML.
<img src="<?php echo $image; ?>" />

Thanks

I know this is 4-5yrs old …
I’m having similar issues. I have the typical repeater (title, image, link) that I would like to randomize. All of my images are showing up all at once. Could someone please help me roll this row randomization into my existing code below?

<?php if( have_rows('billboard') ): ?>

	<?php while( have_rows('billboard') ): the_row(); 

		// vars
		$image = get_sub_field('image');
		$link = get_sub_field('link');

		?>

			<?php if( $link ): ?>
				<a href="<?php echo $link; ?>">
			<?php endif; ?>

				<img class="billboard" src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt'] ?>" />

			<?php if( $link ): ?>
				</a>
			<?php endif; ?>

	<?php endwhile; ?>

<?php endif; ?>
