Sortby date created image

1

I’m trying to sort by dateCreated of the image. There is though not explicit field that would store this information, rather it’s in the binary field it-self:

<?php foreach ($site->find('projekte')->children()->images()->filterBy('category', $page->uri(), ',')->sortBy('dateCreated', 'desc') as $img): ?>

      <div class="col-lg-6 p-3 p-xl-5">
       <div class="portfolio-image">
            <img class="img-fluid w-100 " src="<?= $img->resize(600)->url() ?>" alt="<?= $img->alt() ?>">
       </div>
      </div>

    <?php endforeach ?>

Unfortunately this doesn’t have any effect. Do I have to explicitely store that information in a field?

dateCreated doesn’t seem to be a default file method, there is modified, but that does something slightly different.

So yes, you’d have to create a field for that, or you could create a fileMethod plugin that retrieves that information from somewhere (like the exif data).

Something like:

/site/plugins/file-methods/index.php

<?php 

use Kirby\Cms\App as Kirby;

Kirby::plugin('my/plugin', [
    'fileMethods' => [
        'dateCreated' => function () {
           $root = $this->root();

           // search exif data
           $ifd0 = @exif_read_data($root, 'IFD0');
           if($date = $ifd0['DateTime'] ?? false) return strtotime($date);

           // try ctime (might work on windows)
           if($date = filectime($root)) return $date;

           // fallback to mtime
           return $this->modified();
        }
    ]
]);

thanks. I went with modified. That’s good enough.
