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