You can get the file in the post variable from the form and here is the code to upload file and saving it into the storage/uploads folder 

$info = pathinfo($_FILES['your_file_name']['name']);
$ext = $info['extension']; // get the extension of the file
$newname = "newname.".$ext; 

$target = 'avatar/'.$newname;
move_uploaded_file( $_FILES['your_file_name']['tmp_name'], $target);

Here is the post which will helps you create random string for the filename (you can save this filename into the database) https://stackoverflow.com/a/13212994/5928015
