I’ve decided to do something like this using a repeater field… not the prettiest thing but it will probably work the way I need it too.
<?php if ( have_rows('apartamento_1_alcoba') ): ?>
<div id="img-module-slider-1" class="vivienda-slider">
<?php while( have_rows('apartamento_1_alcoba') ) : the_row();
$icono_1_alcoba = get_sub_field('icono');
$gallery = get_sub_field('lightbox');
$id_1_alcoba = get_sub_field('plano_id');
?>
<section data-featherlight-gallery data-feather-filter="a">
<?php if ( $gallery ): ?>
<?php foreach ( $gallery as $image ): ?>
<a class="apt-gallery-<?php echo $id_1_alcoba ?>" href="#" data-featherlight="image">
<img class="module-img-size" src="<?php echo $icono_1_alcoba['url'] ?>" alt="<?php echo $icono_1_alcoba['alt'] ?>">
</a>
<a class="apt-gallery-<?php echo $id_1_alcoba ?>" href="<?php echo $image['url'] ?>" alt="<?php echo $image['alt']?>"></a>
<?php endforeach; ?>
<?php endif; ?>
</section>
<?php endwhile; ?>
</div>
<?php endif; ?>
However, I’d like to be able to get just the first image of the gallery in the for each, how can I do that?
