I have a repeater field inside a flexible content block.
I need to count the number of repeater rows so I can give class to the wrapper, for columns.

Setup like so, you can see the $num_cols variable I am trying to fill in with a count, obviously does not work 🙂

if( have_rows('columns') ) :
	$num_cols = count( get_sub_field('columns') ); ?>

	<div class="grid-col-<?php echo $num_cols; ?>">
		<?php
		while ( have_rows('columns') ) : the_row(); ?>
		<div class="column">
			<p class="column-title"><?php the_sub_field('title'); ?></p>
		</div>
	<?php endwhile; ?>
	</div>

 <?php endif; ?>

I guess this works:

$num_cols = count( get_field('columns') );

if the repeater is a sub field of a flex field then you need to use get_sub_field()

$num_rows = count(get_sub_field('columns'));

Yeah I had tried that as well, that is the second line in my code block above 🙂

Here is how it is setup, the repeater is in a flexible content set,

Do you have a loop for the flex field?

if (have_rows('flex_field_name')) {
  while (have_rows('flex_field_name')) {
    if (get_row_layout() == 'column_blocks') {
      $num_rows = count(get_sub_field('columns'));
      // etc...
    }
  }
}
