     */
    public function index()
    {
        return View::make('blog.index');
    }
    /**
     * Show the form for creating a new resource.
     *
     * @return Response
     */
    public function create()
    {
        //
        return View::make('blog.create');
    }
    /**
     * Store a newly created resource in storage.
     *
     * @return Response
     */
    public function store()
    {
        $Input = Input::all();
        $rules = array(
            'username'  => 'required',
            'password'  => 'required',
            'rpassword' => 'required|same:password',
            'email'     => 'required|email',
            'sex'       => 'required|boolean'
        );
        $validator = Validator::make($Input, $rules);
        if ($validator->fails())
        {
          //dd('123');
          return Redirect::to('/create')->withErrors($validator, 'login');
        }
          //  dd('456');
        return Redirect::to('/');
    }
.form 表单验证

</div>
<script type="text/javascript">
