PHP Form and Mini MySQL Tables

[jameseymour]

I am making a PHP form that will store all records into a MySQL database.

However, there are a number of listboxes on the form (Employee, Operating System, and so on) Each one has a list of items in it. These items are records in a few small tables (EmployeeTable, OperatingSystemTable, etc.) If an item is not in the list, there is a textbox that you can type a new item in. Once typed I want the table to have the new item added to it, and then the listbox to update and have the new item located in it aswell for selecting.

If anyone has any idea how I should approach this it would be appritiated.

Also, with PHP would I be able to update the listbox itself with the mysql table? Or would I need some java?

Thanks for any help you can give.
