  27  * We're now using the HTMLForm object with some customisation to generate the
  28  * Preferences form. This object handles generic submission, CSRF protection,
  29  * layout and other logic in a reusable manner. We subclass it as a PreferencesForm
  30  * to make some minor customisations.
  31  *
  32  * In order to generate the form, the HTMLForm object needs an array structure
  33  * detailing the form fields available, and that's what this class is for. Each
  34  * element of the array is a basic property-list, including the type of field,
  35  * the label it is to be given in the form, callbacks for validation and
  36  * 'filtering', and other pertinent information. Note that the 'default' field
  37  * is named for generic forms, and does not represent the preference's default
  38  * (which is stored in $wgDefaultUserOptions), but the default for the form
  39  * field, which should be whatever the user has set for that preference. There
  40  * is no need to override it unless you have some special storage logic (for
  41  * instance, those not presently stored as options, but which are best set from
  42  * the user preferences view).
  43  *
  44  * Field types are implemented as subclasses of the generic HTMLFormField
  45  * object, and typically implement at least getInputHTML, which generates the
  46  * HTML for the input field to be placed in the table.
  47  *
  48  * Once fields have been retrieved and validated, submission logic is handed
  49  * over to the tryUISubmit static method of this class.
