<body>
<?php echo $this->validation->error_string;?>
<?php echo form_open('form/index');?>
<h5>Username</h5>
<input type="text" name="username" value="" size="50" />
<h5>Password</h5>
<input type="text" name="password" value="" size="50" />
<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<?php
class Form extends Controller{
 function index(){
 $this->load->helper(array('form','url'));
 $this->load->library('validation');
   $rules['username'] = "required";
    $rules['password'] = "required";
    $rules['passconf'] = "required";
    $rules['email'] = "required";
    $this->validation->set_rules($rules);
 //    $this->validation->set_error_delimiters('<div class="error">','</div>');
 $fields['username'] = 'Username';
 $fields['password'] = 'Password';
 $fields['passconf'] = 'Password Confirmation';
 $fields['email'] = 'Email Address';
 $this->validation->set_fields($fields);
   if ($this->validation->run()==false) {
   $this->load->view('MyView/myform');
   }else {
   $this->load->view('MyView/formsuccess.php');
   }
 }
}
?>
