Event for detecting Asset File Change

[lukasIO]

Hi,

is there a way to detect when the file of an asset has been changed?
Which means, I would like to ignore when other fields (title etc.) have been changed and only react to either: Upload, editImage, replace

I was looking at Asset::EVENT_AFTER_SAVE but unfortunately that event is (understandably) being triggered each time the asset's field value changes/save button is pressed and on top of that it is triggered once for each site.

I also found Assets::EVENT_AFTER_REPLACE_ASSET which gets me half-way there, but I couldn't figure out how to listen to the initial upload/and or image edits.

Thanks!

You can check the asset’s scenario from EVENT_AFTER_SAVE to get an idea of what’s happening with the file.

use craft\elements\Asset;
use craft\events\ModelEvent;
use yii\base\Event;

Event::on(Asset::class, Asset::EVENT_AFTER_SAVE, function(ModelEvent $event) {
    /** @var Asset $asset */
    $asset = $event->sender;
    $scenario = $asset->getScenario();

    if (in_array($asset->getScenario(), [
        Asset::SCENARIO_CREATE,
        Asset::SCENARIO_MOVE,
        Asset::SCENARIO_REPLACE,
        Asset::SCENARIO_FILEOPS,
    ])) {
        // something is happening with the actual file
    }
});
