Fetching sort order from files via files field

The CMS Questions
1

Hi all - I’m am looping files added by the file field type, and hoping to fetch the sort number of the file so I can use it for an animation delay variable as shown in the markup below (data-aos-delay=“<?= $logo->id()?>00”). This helps me create a sequenced fade in effect. When using files added via a structured item I can use the ‘id’ but when they are just files I have tried various options and can’t get anything. Is there a way this can be done or do the files need to be added to as structured items to do this?

Blueprint:

supplierLogos:
        type: files
        layout: cards

Markup:

<?php
$logos = $site->supplierLogos()->toFiles();
foreach($logos as $logo): ?>
<div class="d-flex aos-init aos-animate" data-aos-delay="<?= $logo->id()?>00" data-aos="fade-in">
  <img src="<?= $logo->url() ?>" alt="" class="img-fluid">
</div>
<?php endforeach ?>

Thanks

What do you mean, the way they are sorted inside the field? Then $logo->indexOf($logos) should do the job.

Gah thanks @texnixe that;'s exactly what I meant. I was messing about with index rather than indexOf - thanks so much, added to my fledgling kirby knowledge for next time!
