I often need to create a multi-page form or load a form with old data. FormSaver helps with both by providing a generic way to save form data.

FormSaver is built to save the data for a form, not the data that a form might represent (which will hopefully make sense shortly).

FormSaver can save the data using either DataMgr or SessionMgr (which is basically a SessionFacade). Just pass in the one you want to use to the init() method of FormSaver (with an argument name of "DataMgr" or "SessionMgr" respectively).

In order to save a form's data, use the store() method with the following arguments:

• formdata: The Form structure itself (so, theoretically, FormSaver could save any simple structure)
• formname: A name by which to reference this form (used for retrieving the value later)
• usertoken: Any string to identify the user (required only if using DataMgr)

 In order to get back the saved structure, use the retrieve() method with the following arguments:

• formname: The name to reference the form you want to retrieve (from the argument of the same name above)
• usertoken: A string to identify the user (again, required only if using DataMgr)

You can also delete a stored form using the delete method with the following arguments: 

• formname: The name to reference the form you want to retrieve (from the argument of the same name above)
• usertoken: A string to identify the user (again, required only if using DataMgr)

When using DataMgr, FormSaver saves data to a table that it creates (via DataMgr). The name of this table is set via the "tablename" argument of the init() method (it defaults to "frmSaveds").

FormSaver is a very simple component that can help you temporarily store form values. This can be helpful for multi-page forms, especially if you want a user to be able to return to a form where they left off in a previous visit.

FormSaver is open source and free for any use.
