Heres my controller:

Code:
&lt;?php
class educ extends CI_Controller
{
public function __construct()
{
  parent::__construct();
  $this->load->helper(array('form', 'url'));
  
  $this->load->model('demo_model');
}
public function display()
{
  session_start();
  $cno = $_SESSION['contractno'];
  /*$_SESSION['sname'] = $_REQUEST['sname'];
  $_SESSION['fname'] = $_REQUEST['fname'];
  $_SESSION['mi'] = $_REQUEST['mi'];
  $_SESSION['dob'] = $_REQUEST['dob'];
  $_SESSION['contractdate'] = $_REQUEST['contractdate'];*/
  $queryr['details'] = $this->demo_model->demodb($cno);
  $this->load->view('demo/display', $queryr);
  
}

public function display2()
{
  session_start();
  $cno = $_SESSION['contractno'];
  $_SESSION['neweadd'] = $_REQUEST['eadd'];
  $_SESSION['newcpnum'] = $_REQUEST['cpnum'];
  $_SESSION['newcpprefix'] = $_REQUEST['cpprefix'];
  
  $queryr['details'] = $this->demo_model->demodb($cno);
  $queryr['demobin'] = $this->demo_model->demobin($cno);
  //print_r($queryr);
  if (count($queryr['details'])<0)
  {
  $this->load->view('demo/display2', $queryr);
  }
  else
  {
   echo "[removed]alert('Email address not valid');[removed]";
   $this->load->view('demo/display');
  }
  
  
}

I guess your problem is that you are not doing any kind of validation buddy. I do not see it anywhere, you are just validating if array has something in the controller
Code:
if (count($queryr['details'])<0)

Read a little of documentation and then come back with your inquiries ;-)

Are you returning an array or object from your demo model?

i change my javascript validation to the CI form validation and i get this error

A PHP Error was encountered

Severity: Notice

Message: Undefined offset: 1

Filename: libraries/Form_validation.php

Line Number: 953


Error Number: 1064

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE ` = 'csampiano@yahoo.com' LIMIT 1' at line 2

SELECT * WHERE ` = 'csampiano@yahoo.com' LIMIT 1

Filename: C:\Program Files\Apache Group\Apache2\htdocs\demonitization\system\database\DB_driver.php

Line Number: 330

i dunno why i have this limit1.. do i ommited something in my model or i need something to change in controller..:-S
