Question

On my index page, I have a drop down list that, when clicked, sends the result via POST to the next page. The next page converts one of the POST variables to a SESSION variable. This is the code:

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

From this page though, I send a POST request to a cart page, which then does the job and goes automatically back to the previous page. The code for this is

      header('Location: '.$page);

The problem is that when this page goes back to the previous one, the SESSION variable cannot be loaded because there is no POST request. How can I go about making sure no error that comes up?

Any tips and code would be great
Thanks

Answer 1

Assuming they click a link that takes them back to this page:

 if(isset($_POST['land']) && !empty($_POST['land'])){ $_SESSION['land']=$_POST['land']; }
