由于使用了 Active Record 类，一般数据库操作只有两层，即是C和V

controllers/login.php文件：

<?php

class Login extends CI_Controller {

private $pass = '';

public function __construct() {

  parent::__construct ();

  $this->load->helper ( array (

    'form',

    'url'

  ) );

  $this->load->library('session');

}

public function index() {

  $this->load->view ( 'login' );

}

public function formsubmit() {

  $this->load->library ( 'form_validation' );

  $this->form_validation->set_rules ( 'username', 'Username', 'required' );

  $this->form_validation->set_rules ( 'password', 'Password', 'required' );

  if ($this->form_validation->run () == FALSE) {

   $this->load->view ( 'login' );

  } else {

   if (isset ( $_POST ['submit'] ) && ! emptyempty ( $_POST ['submit'] )) {

    $data = array (

      'user' => $_POST ['username'],

      'pass' => md5($_POST ['password'])

    );

    $newdata = array(

      'username'  =>  $data ['user'] ,

      'userip'     => $_SERVER['REMOTE_ADDR'],

      'luptime'   =>time()

    );

    if ($_POST ['submit'] == 'login') {

     $query = $this->db->get_where ( 'uc_user', array (

       'user' => $data ['user']

     ), 1, 0 );

     foreach ( $query->result () as $row ) {

      $pass = $row->pass;

     }

     if ($pass == $data ['pass']) {

      $this->session->set_userdata($newdata);

      $this->load->view ( 'usercenter', $data );

     }

    } else if ($_POST ['submit'] == 'register') {

     $this->session->set_userdata($newdata);

     $this->db->insert ( 'uc_user', $data );

     $this->load->view ( 'usercenter', $data );

    } else {

     $this->session->sess_destroy();

     $this->load->view ( 'login' );

    }

   }

  }

}

}

views/login.php文件：

<html>

<?php echo validation_errors(); ?>

<?php echo form_open('login/formsubmit'); ?>

<table>

<tr>

<td>用户名</td>

<td><input type="text" name="username"></td>

</tr>

<tr>

<td>密码</td>

<td><input type="password" name="password"></td>

</tr>

<tr>

<td>

<input type="submit" name="submit" value="login">

</td>

<td>

<input type="submit" name="submit" value="register">

</td>

</tr>

</table>

</form>

</html>

sql语句：

uc_user：

CREATE TABLE `uc_user` (

           `id` int(11) unsigned zerofill NOT NULL AUTO_INCREMENT,

           `user` varchar(20) NOT NULL,

           `pass` char(32) NOT NULL,

           `role` enum('root','normal') NOT NULL DEFAULT 'root',

           `del` decimal(1,0) NOT NULL DEFAULT '0',

           PRIMARY KEY (`id`)

         ) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=latin1
