I’ve managed to get @hube2 solution to work, but with help from (for me) a bit clearer code:
You’ll need to start a counter just above your while loop: $counter = 0; Then just before your closing endwhile; you’ll need to advance the counter: $counter ++;
Then simply print the number of that loop like this:
<?php print "$counter"; ?> or <div class="name-<?php print "$counter"; ?>"
