Hi, I am new to session of php. I need pass the form content from the the first page all the way down to the last page to process it. I used to use $_POST['sth'] to pass the data, but it is very painful since there are several pages between the first and last page. I am using $_SESSION['sth'] now. It saves a lot of time, but when I clicked the 'Back' button on the tool bar, I always got the message "The page cannot be displayed". Can you help me?
