未定义的属性:stdClass :: $ 1试图检索POST

I am trying to access a post input value in my controller. Any help finding out what I am doing wrong here ?

Here is my Controller

class Login extends MY_Controller {


public function __construct() {
    parent::__construct();
    $this->load->model('Users_model');
    $this->load->helper('form_helper');
}


public function index()
{

    $this->load->view('templates/header');
    $this->load->view('login');
    $this->load->view('templates/footer');
}

public function authenticate(){
    if($this->input->post('submit')){
        $id  = $this->input->post('id');

    $query = $this->db->get_where('users', array('id' => $id));

    foreach ($query->result() as $row)
    {
       echo $row->$id;
       echo $row->email;
       echo $row->password;
    }

    }


}

}

The Login Form

<?php echo form_open('login/authenticate') ?>

<label for="title">Title</label>
<input type="input" name="id"/><br/>



<input type="submit" name="submit"  />

The above code gives an error as

A PHP Error was encountered

Severity: Notice

Message: Undefined property: stdClass::$1

Filename: controllers/login.php

Thanks, any help much appreciated. :)
