How to rename uplaoded file ?

[vitalijalbu]

Hi guys, anyone can help me with a simple task? I'd like to rename every file to random md5 after uploading, upload works but doesn't rename...
My code:

<?php

namespace modules\media;

use Craft;
use craft\elements\Asset;
use craft\events\ModelEvent;
use yii\base\Event;
use yii\base\Module as BaseModule;

/**
 * media module
 *
 * @method static Module getInstance()
 */
class Module extends BaseModule
{
    public function init()
{
    // Find the "media" volume once during module initialization
    $volume = Craft::$app->getVolumes()->getVolumeByHandle('media');

    if ($volume === null) {
        Craft::error('Unable to retrieve volume with handle: media', METHOD);
        return;
    }

    // Register the event listener
    Event::on(
        Asset::class,
        Asset::EVENT_BEFORE_HANDLE_FILE,
        function(AssetEvent $event) use ($volume) {
            // Get the root path of the volume
            $rootPath = $volume->settings['rootPath'];

            // Generate a new filename
            $extension = pathinfo($event->asset->filename, PATHINFO_EXTENSION);
            $newFilename = md5(time()) . '.' . $extension;

            // Set the new filename on the asset
            $event->asset->setFilename($newFilename);

            // Set the new path on the event parameter to ensure that the uploaded file is saved with the new filename
            $event->params['path'] = $rootPath . DIRECTORY_SEPARATOR . $newFilename;
        }
    );
}

}

Used this piece of code, when we had to obfuscate filenames, maybe it helps:

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

        if (! ... skip if this file should not be renamed... .) {
            return;
        }

        $newFilename = "$asset->uid.$asset->extension";

        // This filename exists already
        if (Asset::find()
            ->folderId($asset->folderId)
            ->filename($newFilename)
            ->exists()) {
            return;
        }

        Craft::$app->assets->moveAsset($asset, $asset->folder, $newFilename);
    }
);

Ok looks good, but what if I'd want to rename the resource also just like the filename?

[wsydney76]

to rename the resource also just like the filename?

That means setting the title to the new filename?

$asset->title = $newFilename;
Craft::$app->assets->moveAsset($asset, $asset->folder, $newFilename);

That should do the trick as the moveAsset method saves the asset element behind the scenes.
