Use get_option() to retrieve existing * values to show. * * @since 2.7.0 * @since 4.2.0 The `$class` argument was added. * * @global $wp_settings_fields Storage array of settings fields and info about their pages/sections * * @param string $id Slug-name to identify the field. Used in the 'id' attribute of tags. * @param string $title Formatted title of the field. Shown as the label for the field * during output. * @param string $callback Function that fills the field with the desired form inputs. The * function should echo its output. * @param string $page The slug-name of the settings page on which to show the section * (general, reading, writing, ...). * @param string $section Optional. The slug-name of the section of the settings page * in which to show the box. Default 'default'. * @param array $args { * Optional.

笔记(Notes)
带标签
我怀疑在标签的“id”属性中使用的可能被重写为在标签的“name”属性中使用的。
$id参数的描述是“在标记的’id’属性中使用”,但是这意味着您必须确保这个$id被用作与字段相关的输入元素的HTML id标记。WP仅使用此$id在其内部设置字段列表($WP_settings_field s)中为字段设置唯一的键。
