Hi, I use repeater field to show (with the js backstretch) different background in every page.

How can hide navigation button if I have only one background image?
Here’s my code. Thank you!

<?php
$post_id = false;
if( is_home() )
{
	$post_id = 17; //  ID of home blog
}

if( get_field('background', $post_id) ):?>

<!-- Nav Buttons --> 
 <div id="next"><img src="<?php bloginfo('template_url'); ?>/img/icon-next.png" /></div>
 <div id="prev"><img src="<?php bloginfo('template_url'); ?>/img/icon-prev.png" /></div>

<script language="javascript">

	 jQuery(document).ready(function($) {
	 
		 	jQuery("body").backstretch([
		 	
		 	<?php while(the_repeater_field('background', $post_id)): ?>
		 		"<?php the_sub_field('image', $post_id); ?>",
		 		
			<?php endwhile; ?>
		 	
		 	], {duration:5000, fade: 800});
		 	
		 	
		}); 

</script>

<?php
endif
?>

Hi @anto.c
You can check the amount of rows like so:

$images = get_field('background', $post_id);

if( count($images) > 1 )
{

}

Hope that helps.

Thanks
