Multipage Forms: Design Question

Hi all Mybe I am OT with my question on this list. If so, please point me to the rigth list to ask this question. I am working on a framework for easyly creating multipage forms (wizard-like) using HTML_QuickForm. I got a basic concept for it and I wanted to ask if there are better ideas around to do it. Let me explain my approach: There are 3 basic classes: - FormPageManager - FormPage - Event FormPageManager: This abstract class is intended to handle the paging of the whole wizard. The structure of the wizard should somehow be known by an extended class derived from the FormPageManager-class. It's task are: - has knowledge about first/last/next/previous pages to display, depending on events triggered by a specific FormPage - hadles events triggered by a FormPage - calls current FormPage methods to display, evaluate and process its form input - uses sessions or object-serialization to remember current page FormPage: This abstract class is intended to represent a specific FormPage in an extendend class. Tasks of this class are: - can validate its form input - can process its form input (maybe by using DB_DataObject) - can display itself - trigers events like prev/next button pressed etc. by triggering events using an event object as return value. Event: This class should manage the "transport" of event-messages from a FormPage-subclass to a FormPageManager-subclass. Its task are: - lets trigger an event providing eventname and a possible action to take. These events will be used by the FormPageManager to take appropriated actions (prev/next etc.) As you can see, there are abstract classes (methodes respectively) that will have to be overwritten by the user of the multipage form framework. I am not shure if this is the PEAR-like approach. Mybe there should be some advanced configuration facility for the whole framework in a way that there is no need for subclassing over and over for every wizard and every wizard page. Furthermore I am not sure if using an event-object is a good solution. I would be very glad to hear your comments, suggestion or tips on developing such a framework. And once again, please point me to the rigth list if I am OT on pear-general. Thanks! -- Cheers! Marco
