  23 /**
  24  * We're now using the HTMLForm object with some customisation to generate the
  25  * Preferences form. This object handles generic submission, CSRF protection,
  26  * layout and other logic in a reusable manner. We subclass it as a PreferencesForm
  27  * to make some minor customisations.
  28  *
  29  * In order to generate the form, the HTMLForm object needs an array structure
  30  * detailing the form fields available, and that's what this class is for. Each
  31  * element of the array is a basic property-list, including the type of field,
  32  * the label it is to be given in the form, callbacks for validation and
  33  * 'filtering', and other pertinent information. Note that the 'default' field
  34  * is named for generic forms, and does not represent the preference's default
  35  * (which is stored in $wgDefaultUserOptions), but the default for the form
  36  * field, which should be whatever the user has set for that preference. There
  37  * is no need to override it unless you have some special storage logic (for
  38  * instance, those not presently stored as options, but which are best set from
  39  * the user preferences view).
  40  *
  41  * Field types are implemented as subclasses of the generic HTMLFormField
  42  * object, and typically implement at least getInputHTML, which generates the
  43  * HTML for the input field to be placed in the table.
  44  *
  45  * Once fields have been retrieved and validated, submission logic is handed
  46  * over to the tryUISubmit static method of this class.
