Explicitly set image sort order

[Mackski]

I'm uploading multiple images via the API.

Is there a way to explicitly set the sort order once uploaded?

eg: something like this would be handy:

foreach($files as $order => $f) {
  $p->images->add($f)->sort($order);
}

Short answer, no.

But there are alphanumeric sort possibilities on run time. As $images is a Wirearray you could do:

$images = $page->images->sort('name');
foreach ($images as $key => $image) {
    echo "$key => " . $image->url . '<br>'; // hyatt2.jpg => /site/assets/files/1/hyatt2.jpg
}

This will, sort the images on filename.

And you can re-save the page with the new sort order.

// Page is previously saved, but now we reset the order
$page->images->sort('name');
$page->of(false);
$page->save();

Does it not make sense to expose the sort field via the API?

Front end example would be drag and drop sorting of user uploaded images.
Having this order saved and mirrored in PW Admin would be ideal.

Not an ideal solution, I ended up renaming the files on upload and append my sorting order on each file name before saving.

ie: {sort_order}_{page->id}.{extension}

Based on this post:

Good solution, you can use the ->setName() when using the example of ryan to rename it ( remove the  {sort_order} )

Thanks Martijn, I did not know that method exists, happy now I can clean up my code...

I also did not know that Source code of ProcessWire is Joyful to read.
