php - Create dynamic HTML ID based off wordpress query -

i wondering how can create dynamic set of ids based off amount of custom posts queried given post.

i'm using advance custom fields plugin , i"m querying custom fields in given post. if take below you'll see have custom fields being queried each 1 wrapped in div id "section-1". need "section-1" update "section-3", "section-4" each time new field name queried. if 5 fields queried each have own id.

<?php  // check if repeater field has rows of data if( have_rows('repeater_field_name') ):  // loop through rows of data while ( have_rows('repeater_field_name') ) : the_row();      // display sub field value     <div id="section-1">     the_sub_field('sub_field_name');     </div>  endwhile;  else :  // no rows found  endif;  ?> 

just set index variable before loop , increment @ each iteration. use inside id.

<?php $index = 1; while ( have_rows('repeater_field_name') ) : the_row(); ?>      <div id="section-<?= $index; ?>">         <?php the_sub_field('sub_field_name'); ?>     </div>  <?php $index++ endwhile; ?>
