Question

is there any way to save JavaScript variable into session value?
Here is my code:

function changePage(newLoc)
{
  subid = newLoc.options[newLoc.selectedIndex].value
}

I need to save subid into session value.

Thanks, in advance.

You will need to use AJAX. I would advise you to use jQuery.

function changePage(newLoc)
{
   subid = newLoc.options[newLoc.selectedIndex].value

    $.ajax({
       url: 'ajac.php',
       data: {"subId":subid},
       type: 'post',
       success:function(data){
           //Succes!
       }
    });

}

And in PHP:

$_SESSION['subId'] = $_POST['subId'];
