CSF::createSection( $prefix, array(
            'title'  => '功能增强',
            'icon'   => 'fas fa-rocket',

                    array(
                        'id'      => 'is_register_gift',
                        'type'    => 'switcher',

                    ),
                ),
            ),
            )
        )
    );

随后把这行代码放在主题的functions.php文件最底部即可

/**

if (_cao('register_gift')['is_register_gift']) {
    add_action('user_register', function ($user_id) {
        update_user_meta($user_id, 'vip_type', _cao('register_gift')['_level']);
        $time = time() + _cao('register_gift')['_day'] * 86400;
        update_user_meta($user_id, 'vip_time', $time);
    });
}
