Getting users' email - Laravel 5 PHP - php

Question

I'm attempting to store the email address of any user who uploads a file into an "uploader_name" string variable. I've attempted using the following code whichout success - attempting to upload the file will result in a Class 'App\Http\Controllers\Auth' not found error message being thrown back. I know this is a pretty basic question, but I can't seem to find any answers which specifically work with Laravel 5.
This is what I'm trying to use currently without success.
$filelist->uploader_name = Auth::user()->email;
If it helps, here's the full function which saves some of the automatic information of the file.
public function store()
{
$filelist = new Filelist($this->request->all());
//store file details - thanks to Jason Day on the unit forum for helping with some of this
$filelist->name = $this->request->file('asset')->getClientOriginalName();
$filelist->file_type = $this->request->file('asset')->getClientOriginalExtension();
$filelist->file_size = filesize($this->request->file('asset'));
$filelist->uploader_name = Auth::user()->email;
$filelist->save();
// Save uploaded file
if ($this->request->hasFile('asset') && $this->request->file('asset')->isValid()) {
$destinationPath = public_path() . '/assets/';
$fileName = $filelist->id . '.' . $this->request->file('asset')->guessClientExtension();
$this->request->file('asset')->move($destinationPath, $fileName);
}
return redirect('filelists');
}

Answer 1

You get not found error, because you don't use the right namespace.
You can resolve this if you use the use keyword like this:
use Auth;
public uploadController {
...
}
Or you can use the full namespace:
$filelist->uploader_name = \Auth::user()->email;

Answer 2

You are getting Class 'App\Http\Controllers\Auth' not found error because you are not using the correct namespace:
There are two ways to resolve this:
By including use keyword in your controller
Example:
use Auth;
UploadController{
....
}
or by specifying the full namespace directly like so
$filelist->uploader_name = \Auth::user()->email;
