Question

I have a question regarding a session variable.

I have session variable which needs to start at a default variable. Then I need to be able to pass a new one through $_GET and keep that updated. So that even if the user reloads the page, it does not go back to the default value. How might I go about doing this? Thanks!

Seems like something along these lines might work:

if(!isset($_SESSION['my_parm']))
{
  $_SESSION['my_parm'] = 'DEFAULT';
}

if(isset($_GET['my_parm']))
{
  $_SESSION['my_parm']=$my_parm;
}
