5
|
* CTools' multi-step form wizard tool.
|
|
6
|
*
|
|
7
|
* This tool enables the creation of multi-step forms that go from one
|
|
8
|
* form to another. The forms themselves can allow branching if they
|
|
9
|
* like, and there are a number of configurable options to how
|
|
10
|
* the wizard operates.
|
|
11
|
*
|
|
12
|
* The wizard can also be friendly to ajax forms, such as when used
|
|
13
|
* with the modal tool.
|
|
14
|
*
|
|
15
|
* The wizard provides callbacks throughout the process, allowing the
|
|
16
|
* owner to control the flow. The general flow of what happens is:
|
|
17
|
*
|
|
18
|
* Generate a form
|
|
19
|
* submit a form
|
|
20
|
* based upon button clicked, 'finished', 'next form', 'cancel' or 'return'.
|
|
21
|
*
|
|
22
|
* Each action has its own callback, so cached objects can be modifed and or
|
|
23
|
* turned into real objects. Each callback can make decisions about where to
|
|
24
|
* go next if it wishes to override the default flow.
