我正在寻找一些关于如何在WordPress中为sterialized数据添加新值的帮助。我正在尝试为已安装的插件添加一个新选项，以便为客户端添加额外功能，并且我需要将“price\\u higher\\u rates”添加到wp_estate_submission_page_fields 阵列输入wprentals_admin.

由于我是WordPress的新开发人员，我曾尝试将数据直接添加到数据库中，但后来出现了一些错误，这是因为我发现数据被序列化了。我已经看到了功能add_option() 和update_option() 但无法找到如何添加新值。

这是wprentals\\u管理员的一个片段wp_estate_submission_page_fields 大堆
