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