php - Find position in while loop -

i have created while loop in wordpress outputs custom field , post data. want inside loop , check find if field matches highlight field , output position iteration.

my users have field in profile called 'schoolname' wan reference against.

$user_info = get_userdata(1);  echo $user_info->schoolname;   $i= 1;  $loop = new wp_query(  array( 'post_type' => 'schools',         'posts_per_page' => -1,         'orderby' => 'signups',        'order'   => 'asc', )  );   while ( $loop->have_posts() ) : $loop->the_post();   echo '<tr>       <td>' . $i++ . '</td>       <td>' . get_the_title() . '</td>       <td>' . $signups = get_field( "signups") . ' signups</td>       </tr>';   endwhile; wp_reset_query(); 

to state of loop use foreach

<?php global $post; // required  $posts = get_posts(); foreach($posts $state => $post) : setup_postdata($post); ... endforeach; ?> 

you can replace while part with foreach part. know iteration number use$state`.

update

<?php $posts = get_posts(array( 'post_type' => 'schools',         'posts_per_page' => -1,        'orderby' => 'signups',        'order'   => 'asc', )); ?>  <?php if ($posts): ?>     <?php foreach ($posts $key => $post): ?>         <?php setup_postdata($post); ?>         <tr>             <td><?= $key; ?></td>             <td><?= get_the_title(); ?></td>             <td><?= get_field( "signups"); ?> signups</td>         </tr>     <?php endforeach; ?>     <?php wp_reset_postdata(); ?> <?php endif; ?>
