If i want to pass this value into session, how can i do?

example_view.php(view)

<html>
<head><title>Test Example View</title></head>

<body>
<h1 align="center">Test Sample CI Framwork</h1>

<?php echo form_open('example/getvalue'); ?>
<input type="text" name="username" value="" size="50" />
<div><input type="submit" value="Submit" name="submit"/></div>
<?php echo form_close(); ?>
</body>
</html>

result.php(view)

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<title>Untitled Document</title>
</head>

<body>
<?php echo 'Your new value is '.$value;?>
</body>
</html>

example.php(controller)

<?php
class Example extends Controller {

 function Example()
 {
  parent::Controller(); 
   $this->load->helper('form');
   $this->load->helper('url');

 }

 function index() {
  $this->load->view('example_view');
  $this->getvalue();
 }

 function getvalue()
{
 if ($this->input->post('submit')==true) {
 $data['value']=$this->input->post('username');
  $this->load->view('result',$data);
 }

}

}
?>

If you are using form_validation too, you can use

set_value('test'); // $_POST['test']

Otherwise use

$this->input->post('test'); // $_POST['test']

In your form, set something like;

$data = array('name' => 'field' => 'value' => $this->input->post('test'));
echo form_input($data);

To get the value in codeigniter from input you can use post

$this->input->post('name');

You can also get the value from a GET method

$this->input->get('name');

I've copied and pasted your code, and everything seems to be working fine for me - I'm a little unclear as to what your problem under "1." is?

As for sessions, the CodeIgniter guide is pretty useful for this: http://codeigniter.com/user_guide/libraries/sessions.html

Essentially, you need to load the session library first with

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

Then you can set session data with

$this->session->set_userdata('some_name','some_value');

So your final function would look something like this

function getvalue()
{
 if ($this->input->post('submit')==true) {
 $data['value']=$this->input->post('username');
 $this->session->('username',$data['value']);
 $this->load->view('result',$data);
 }
}

You can then retrieve the data by calling $this->session->userdata('item'), so for your code

echo $this->session->userdata('username');

should output whatever has been put into the textbox (but don't forget to run some security checks on the input box first!)
