/**
|
|
* Represents a field in a form.
|
|
*
|
|
* A FieldList contains a number of FormField objects which make up the whole of a form.
|
|
*
|
|
* In addition to single fields, FormField objects can be "composite", for example, the
|
|
* {@link TabSet} field. Composite fields let us define complex forms without having to resort to
|
|
* custom HTML.
|
|
*
|
|
* To subclass:
|
|
*
|
|
* Define a {@link dataValue()} method that returns a value suitable for inserting into a single
|
|
* database field.
|
|
*
|
|
* For example, you might tidy up the format of a date or currency field. Define {@link saveInto()}
|
|
* to totally customise saving.
|
|
*
|
|
* For example, data might be saved to the filesystem instead of the data record, or saved to a
|
|
* component of the data record instead of the data record itself.
|
|
*
|
|
* @package forms
|
|
* @subpackage core
