Emulate natsort

[adrian]

Hey guys,

Is there any way to emulate PHP's natsort using PW's sort functionality?

I have image filenames with numbered suffixes and of course they aren't ordering correctly with a standard sort.

Thanks

Without emulating

$imgArray = $images->getArray();
natsort($imgArray);
// continue with $imgArray or...
$images = new WireArray();
$images->import($imgArray);

Not tested

Thanks Wanze,

Was hoping there was a PW way. I ended up using the following:

$images = $page->$image_field->getArray();
natsort($images);

$reversed_images = array_reverse($images);

$sortedImages = new WireArray();
$sortedImages->import($reversed_images);

$page->$image_field = $sortedImages;

I had to reverse the array, I am guessing because of the way import brings them in, so that they are in the correct ascending order. After the final line I make a few more changes to the $page and then save it.

Anyway, this seems to work fine.
