Sending an e-mail to current user in FeedMe hook

Question

I have made a custom module that allows a user to upload a CSV and import it using a FeedMe feed. This all works fine, however I want to send an e-mail to the user when the import has completed.

I have this so far, but realised it doesn't work because the event doesn't have access to the user session:

Event::on(Process::class, Process::EVENT_AFTER_PROCESS_FEED, function(FeedProcessEvent $event) {                
    $email = Craft::$app->getUser()->getIdentity()->email;
    if ($event->feed->id === getenv('USER_FEED_ID')) {
        $message = new Message();
        $message->setTo($email);
        $message->setSubject("Import complete");
        $message->setHtmlBody('Data has been imported successfully');
        $message->send();
    }         
});

I've been scratching my furry head but can't think of a solution, is there any way to do this?

Answer 1

As long as you have control of the CSV on upload, you could change its name to [email protected] (or some other properly escaped filename with the current user's email address in it). Then get the filename from the feed (must be in there somewhere) and extract the email address.

Bit of a workaround, but if it works, it works.
