Hi

Im trying to get a field for the previous and next row of a repeater using the foreach method. Can anyone please advise me on the best way to do this or point me in the right direction.

Appreciate any help, thanks.

Hi

You can try something like this with the index when you are doing the foreach loop:

<?php

$repeater = get_field('repeater_name');
$repeaterCount = count($repeater);

foreach ($repeater as $index => $row) {
    // if it's not the first row, that means we have a previous row
    $previousRow = $index == 0? null : $repeater[$index - 1];

    // if it's not the last row, that means we have a next row
    $nextRow     = $index == ($repeaterCount - 1)? null : $repeater[$index + 1];

    ... code
}

Cheers

Hi @gummi thanks for taking the time to help. I still don’t quite understand 100%. My code so far is below.

Ideally, Im looking to pull in the previous and next title field in my loop, a long with the current loop title.

<?php

$blocks = get_field('fbs');

if( $blocks ) :

$count = 1;

?>

<div id="fullpage">

	<?php foreach( $blocks as $block ) :

	// ACF Vars

	$image	= $block['fb_main_image'];
	$imagePos = $block['fb_main_image_fp'];

	$title 		= $block['fb_title'];
	$text		= $block['fb_text'];

	$link 		= $block['fb_link'];
	$linkText   = $block['fb_link_text'];

	?>

	<div class="section" data-anchor="section-<?php echo $count; ?>" style="background-image: url(<?php echo $image['url']; ?>);">

		<section class="o-block">

			<div class="o-container o-container--top">
				<h2 class="o-type-60 u-mb-x4 u-colour-white">GET PREVIOUS TITLE HERE</h2>
			</div>

			<div class="o-container">

			<h2 class="o-type-100 u-mb-x4 u-colour-white"><?php echo $title; // Current Title?></h2>

			</div>

<div class="o-container">

			<h2 class="o-type-100 u-mb-x4 u-colour-white">GET NEXT TITLE</h2>

			</div>
</section>
						<!-- .o-block -->

					</div>
					<!-- .section -->

					<?php $count++; endforeach; ?>

				</div>
				<!-- #fullpage -->

				<?php endif; ?>

Hi,

if you look at the code i posted, you’d need to change your code as following:

1. store the total repeater count before you run the foreach loop:
$blocksCount = count($blocks);

2. add the index when you are doing the foreach:
<?php foreach( $blocks as $index => $block ) :

3. your next and previous row will be the following:
$previousRow = $index == 0? null : $blocks[$index - 1];
$nextRow = $index == ($blocksCount - 1)? null : $blocks[$index + 1];

4. now you can get the title of the previous and next like so:
$previousTitle = $previousRow['fb_title'];
$nextTitle = $nextRow['fb_title'];

Cheers.
