Maybe I could use an easier method. Like this (extra while loop with $i++) to get unique classes:

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

    <?php $flexibleSlider = 0 ?>
    <?php while( have_rows('_post_slider') ) : the_row(); ?>
        <?php $flexibleSlider++; ?>
    <?php endwhile; ?>

    <div class="row slider-wrapper">
        <div class="col-md-12">
        <div class="slider_inner slider-<?php echo $flexibleSlider; ?> ">
            <?php 
                $count_dataindex = 0;
                $count_dataid = 0;
            ?>
            <?php while( have_rows('_post_slider') ) : the_row(); ?>
                <?php $count_dataindex++; ?>
                <article class="" data-index="<?php echo $count_dataindex; ?>" data-slidertitle="<?php the_sub_field('_headline'); ?>">
                    <?php $image = get_sub_field('_bild'); ?>
                    <figure style="background-image: url(<?php echo $image['sizes']['img-l']; ?>)"></figure>
                    <?php if ( get_sub_field('_headline') ) : ?>
                        <div class="slider-headline" data-id="<?php echo $count_dataid; ?>">
                            <?php echo get_sub_field('_headline'); ?>
                        </div>
                    <?php endif; ?>
                </article>
            <?php endwhile; ?>
        </div>
        </div>
    </div>

    <script>
        jQuery(document).ready(function($){
            $('.slider-<?php echo $flexibleSlider; ?> ').slick({
                infinite: true,
                slidesToShow: 1,
                slidesToScroll: 1
            });
        });
    </script>
    
<?php endif; ?>

EDIT: Hm no. I get “slider-4”, “slider-3”, “slider-3” … .
