I'll take a shot at posing this question where you all can understand what it is I am trying to do.
I have a file called customers.php which gets a customer list from a MySQL table. It also has a menu with items like 'add customer', 'edit customer', delete customer'. So far, so good. I am wandering if there is a way to have php display a different area of the customer.php page based on the link they click. For example, the page would default to a customer list. If the user selects 'add customer', the page would 'jump' to the section of the page where the 'add' form resides and display the form, etc, etc.
I can get this to work using multiple pages (ie; customers.php, add_customer.php, etc). It would be nice though if I could have all the code pertaining to customer management in one page.
