I have a contact form in html with captcha image.The Captcha image is randomnly created using a php file and stored in a session variable.

But when i check whether the session (captcha variable) and the use entered captcha value i dont get answer.

posting my code below

 

contact.php(html's action page)
if(isset($_POST['csubmit']))
{
$name=$_POST['cname'];
$lname=$_POST['last_name'];
$email=$_POST['cemail'];
$tele=$_POST['telephone'];
$comments=$_POST['comments'];
$date_posted=date('Y:m:d H:i:s');$status='Inactive';
$security_code=$_POST['security_code'];
//echo $security_code;
//echo"<br>". $_SESSION['security_code'];

//$_SESSION['security_code'] = $code;
//echo $_SESSION['security_code'];
//if( $_SESSION['security_code'] == $_POST['security_code'] && !empty($_SESSION['security_code'] ) ) {
//if(!(empty($_SESSION['security_code'] ) ||strcmp($_SESSION['security_code'], $_POST['security_code']) != 0))

//if(empty($_SESSION['security_code'] ) || $_POST['security_code']) != 0)
  

//if( $_SESSION['security_code'] == $_POST['security_code'] && !empty($_SESSION['security_code'] ) ) {
$sql="insert into contact_us(first_name,last_name,email,contact_number,comments,status,date_posted) values('$name','$lname','$email','$tele','$comments','$status','$date_posted')";
$res=mysql_query($sql);

?>
