If WordPress Repeater has 1 field, 2 fields etc else

I have a repeater that I would like to alter based on how many fields it out puts

the code I have for the basic repater:

<?php // REAPEATER FIELD
if(get_field('whatever')): ?>
  <?php while(has_sub_field('whatever')): ?>

    <div class="whatever_block">
      <?php the_sub_field('anything'); ?>
    </div>

  <?php endwhile; ?>
<?php endif; ?>

How I want it to look:

<?php // REAPEATER FIELD
if(get_field('whatever')): ?>
  <?php while(has_sub_field('whatever')): ?>

    //if only one
    <div class="col-sm-12">
      <?php the_sub_field('anything'); ?>
    </div>

    //if only two
    <div class="col-sm-6">
      <?php the_sub_field('anything'); ?>
    </div>

    //if etc

    //else
    <div class="whatever_block">
      <?php the_sub_field('anything'); ?>
    </div>

  <?php endwhile; ?>
<?php endif; ?>

How I can achieve the above above output with if statements? are if statements even the correct way to go?

You can do a count on the repeater to check how many sub fields it has. Here is a solution using the ACF v4.xx have_rows syntax (should nevertheless work with get_field as well):

if( have_rows( 'parent_whatever' ) ) {
    $posts_no = get_field( 'parent_whatever' );
    while( have_rows( 'parent_whatever' ) {
        the_row();
        $class = "col-sm-" . 12/$posts_no;

        echo '<div class="' . $class . '">';
        the_sub_field( 'whatever' );
        echo '</div>';
    endwhile;
endif;

Ok, this uses the count() function to count the fields, then use a switch case to set a class for your div, like this:

<?php // REAPEATER FIELD
if(get_field('whatever')): ?>
    <?php switch(count(get_field('whatever'))) :    //checks total fields set
        case '1':
            $divClass = 'oneField';
            break;
        case '2':
            $divClass = 'twoField';
            break;
        case '3':
            $divClass = 'threeField';
            break;
        case '4':
            $divClass = 'fourField';
            break;
    endswitch; ?>
    <?php while(has_sub_field('whatever')): ?>

        <div class="<?php echo $divClass; ?>">
          <?php the_sub_field('anything'); ?>
        </div>

    <?php endwhile; ?>
<?php endif; ?>

Just replace 'oneField', 'twoField', ect with your desired class names, and you should be set.
