Great Ideas!
My technicians will load up a ticket, and then manipulate it such as:
showTicket.php
$myTicket = new Ticket();
$myTicket -> setID($id); // sets the ID of the current ticket
$myTicket -> display(); //displays the current ticket
Now, what if they want to add a note to that current ticket:
addTicketNote.php
$myTicket = new Ticket();
$myTicket -> setID($id);
$myTicket -> addNote($username,$note);
What you are saying, is at the end of my Ticket class, insert:
$myTicket = new Ticket();
And then just keep passing the $ID around as session variables?
I hope I understood you right. Makes sense.
