我在OpenCart的管理部分创建了一个注册页面，我们在其中询问详细信息，例如姓名、电子邮件、电话、国家/地区、州/地区、密码和许多其他信息。除国家和地区表单字段外，一切正常。每当我打开表格时，我发现总是选择一个国家，并且区域字段中没有显示任何内容。这是第一个问题。当我选择另一个国家时，它会加载state/zone，如果一切顺利，那么用户就会注册。但是如果表单有任何错误，那么当它在页面上显示错误时，状态/区域值会再次丢失。我必须重新选择国家，然后显示区域。我已经通过“回声”检查该区域的值已转移到此页面，但未显示在下拉列表中。这是我的主要问题。
这是第一张图片的链接——
现在这是显示错误消息的第二张图片——
现在有人请告诉我我该怎么办？我不是opencart的专家。我刚刚第一次创建了这个。我也没有 jquery 或 javascript 的知识。请告诉我应该将哪一部分代码放在这里以获得解决方案。
谢谢 ！！
