Example:

Code:
$data['stud_id'] = $_POST['stud_id'];

 $data['hostel_id'] = $_POST['hostel_id'];

 $this->load->view('hostel/room_allocate', $data);

In view file

Code:
<div class="stud_id">

      &lt;?=$stud_id?&gt;

  </div>

  <div class="hostel_id">

Is "selected" where you expect it to show in the source? If so, then you logic is correct. It's just that you have the syntax wrong.

You set an option as selected by using:

Code:
<option value="foo" selected="selected">bar</option>

Hope this helps.

I can't see where the problem is. I can only assume it has something to do with $this->view->render(). What library are you using to handle your views?

Are you sure it takes an array as the second parameter? What happens when you do this:

Code:
...

$this->view->student_id = $_POST['student_id'];

$this->view->hostel_id = $_POST['hostel_id'];

$this->view->render('hostel/room_allocation');

I don't understand your problem. From the code you've posted, you have a pretty good idea of what to do.
