the controller code :
public function update(Request $request, $id)
{
$users = User::find($id);
if (!$users) {
return back()->with('Error','user created');
}
$users->update($request->all());
return back()->with('Success','user created');
}

Your button
<button class="btn btn-success btn-block">Modifier</button>,
should be
<button class="btn btn-success btn-block" type="submit">Modifier</button> in order to submit the form to your controller.
