   3  * We're now using the HTMLForm object with some customisation to generate the
   4  * Preferences form. This object handles generic submission, CSRF protection,
   5  * layout and other logic in a reusable manner. We subclass it as a PreferencesForm
   6  * to make some minor customisations.
   7  *
   8  * In order to generate the form, the HTMLForm object needs an array structure
   9  * detailing the form fields available, and that's what this class is for. Each
  10  * element of the array is a basic property-list, including the type of field,
  11  * the label it is to be given in the form, callbacks for validation and
  12  * 'filtering', and other pertinent information. Note that the 'default' field
  13  * is named for generic forms, and does not represent the preference's default
  14  * (which is stored in $wgDefaultUserOptions), but the default for the form
  15  * field, which should be whatever the user has set for that preference. There
  16  * is no need to override it unless you have some special storage logic (for
  17  * instance, those not presently stored as options, but which are best set from
  18  * the user preferences view).
  19  *
  20  * Field types are implemented as subclasses of the generic HTMLFormField
  21  * object, and typically implement at least getInputHTML, which generates the
  22  * HTML for the input field to be placed in the table.
  23  *
  24  * Once fields have been retrieved and validated, submission logic is handed
  25  * over to the tryUISubmit static method of this class.
