How to get count of rows in repeater, in flexible content

  • 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; ?>">
    		while ( have_rows('columns') ) : the_row(); ?>
    		<div class="column">
    			<p class="column-title"><?php the_sub_field('title'); ?></p>
    	<?php endwhile; ?>
     <?php endif; ?>
  • I guess this works:

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

  • That does not work no… Had tried that before as well

  • 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...
