Error: Undefined variable: id

Answer 1

Hope this helps or answers your question. Try this;
public function deleteUser($id)
{
User::find($id)->delete();
return redirect('empresa');
}

Answer 2

Just to help you visualize what Nigel and Deepak are saying:
deleteUser() has to be accept an argument called $id
deleteUser($id) { ... }
So when you call deleteUser() make sure to pass in your id (parameter) value:
deleteUser(17);
Hopefully that helps you see what they're talking about.

Answer 3

You will first have to find your user to delete them:
$user = User::find($id);
Then you'll be able to call the delete method:
$user->delete();
You may wish to consider handling the possibility that this user might be null. There are a few ways to accomplish this:
Check if the user is null before calling delete
Using the findOrFail method when finding a user
Option 2 will throw a ModelNotFoundException which you can configure your application to handle this globally and return a 404 page or whatever you might want.
Option 1:
public function deleteUser($id)
{
$user = User::find($id);
if (null !== $user) {
$user->delete();
}
return redirect('empress');
}
Option 2:
public function deleteUser($id)
{
$user = User::findOrFail($id);
$user->delete();
return redirect('empress');
}
Notice that on Option 2 we don't need a null check as an exception is thrown if the user is not found by using findOrFail.
