Laravel:POST函数中未定义的变量

>我正在尝试发送一个包含变量的post请求，但它说变量未定义，这是我的代码..第一个函数是包含窗体的视图。第二个函数是表单的 post 请求的回调。我在视图中回显了变量，它成功了，但错误出现在第二个函数中......

public function reset($code)
{
    return View::make('recover', array('code' => $code, 'passwordReset' => 1,'noLoginForm' => 1));
}
public function postResetPassword()
{
    $validator = Validator::make(Input::all(), array('temppassword' => 'required','newpassword' => 'required|min:6','cnewpassword' =>'required|same:newpassword'));
    if($validator->fails())
        return View::make('recover', array('passwordReset' => 1,'noLoginForm' => 1))->withErrors($validator);
    else {
// The error shows up in the following line in the code variable comparison
        $user = User::where('temp_password','!=','')->where('code','=',$code)->first();
        if($user) {
            $user->password = Hash::make(Input::get('newpassword'));
            $user->temp_password = '';
            if($user->save())
                return Redirect::route('login')->with('msg','Password changed correctly, use your new password to login.');
        } else {
            return View::make('recover', array('passwordReset' => 1,'noLoginForm' => 1,'error' =>'Invalid temporary password, please make sure you typed the password sent to you correctly.'));
        }
    }
}

这是错误日志
