count repeater fields, create columns

I want to display a different amount of columns depending on the amount of sub fields in a repeater field. for example
if there are 2 fields, class d-1of2
if there are 3 fields, class d-1of3
if there are 4 fields, class d-1of4
and so on.

here’s my example for 2 fields:

<?php if( have_rows('spalten') ): ?>
    <?php while( have_rows('spalten') ): the_row(); 
        // vars
        $title = get_sub_field('spaltentitel');
        $content = get_sub_field('spalteninhalt');
        ?>
        <div class="d-1of2">
            <h2><?php echo $title; ?></h2>
            <?php echo $content; ?>
        </div>
    <?php endwhile; ?>
<?php endif; ?>

is this possible?

Hi @irenehofer,

Yup, it’s possible; there’s a few different strategies.
One you could use something alone the lines of:

$count = count( get_field( 'spalten' ) );
echo $count;

To then concatenate + create the class name you’d like and then echo it where desired.

A more elaborate way is detailed in this thread, if you want to check that out as well. Let me know if there’s anything I can clarify!
