How to count the number of repeater fields within a flexible layout?

I’m trying to get a count for the number of columns in my multi-column_row so I can use the number of columns when building my layout. I feel like i’ve tried every example I could find but I still can’t seem to get the number of rows BEFORE doing my while loop.

Here’s my ACF Loop:

<?php if ( have_rows( 'content' ) ): ?>
<?php while ( have_rows( 'content' ) ) : the_row(); ?>
<?php if ( get_row_layout() == 'text_on_white' ) : ?>
<?php the_sub_field( 'anchor_link' ); ?>
<?php the_sub_field( 'text' ); ?>
<?php elseif ( get_row_layout() == 'centered_video' ) : ?>
<?php the_sub_field( 'anchor_link' ); ?>
<?php $thumbnail_image = get_sub_field( 'thumbnail_image' ); ?>
<?php if ( $thumbnail_image ) : ?>
" alt="<?php echo esc_attr( $thumbnail_image['alt'] ); ?>" />
<?php endif; ?>
<?php the_sub_field( 'video_url' ); ?>
<?php elseif ( get_row_layout() == 'multi-column_row' ) : ?>
<?php the_sub_field( 'anchor_link' ); ?>
<?php if ( have_rows( 'columns' ) ) : ?>
<?php while ( have_rows( 'columns' ) ) : the_row(); ?>
<?php $image = get_sub_field( 'image' ); ?>
<?php if ( $image ) : ?>
" alt="<?php echo esc_attr( $image['alt'] ); ?>" />
<?php endif; ?>
<?php the_sub_field( 'wysiwyg' ); ?>
<?php endwhile; ?>
<?php else : ?>
<?php // No rows found ?>
<?php endif; ?>
<?php elseif ( get_row_layout() == 'divider_line' ) : ?>
<?php // Warning: Layout 'divider_line' has no sub fields ?>
<?php endif; ?>
<?php endwhile; ?>
<?php else: ?>
<?php // No layouts found ?>
<?php endif; ?>

I’ve tried
$count = count(get_field('grid_block'));
<?php
$cards = get_sub_field('card');
if(have_rows('card')):
$number_of_cards = count($cards);
endif; ?>

and neither are working. Any tips?

I don’t see how the second parts of your code fit into the first.

To get the count of rows it is either

$count = count(get_field('repeater_field_name'));

OR

$count = count(get_field('repeater_field_name'));

depending, of course if it is a sub field.

In any case you must get the count of rows before calling have_rows() for the repeater you want the count of.
