非常感谢您的帮助。

我在php 5.4中遇到了与php代码相同的问题，但当我在php 7中测试时，jQuery post方法不起作用。所以我从jQuery文档中发现

jqXHR.success（）、jqXHR.error（）和jqXHR.complete（）回调方法是 从jQuery 3.0开始删除。您可以使用jqXHR.done（）、jqXHR.fail（）和 改为jqXHR.always（）

---

因此，对我有效的方法是更改回调函数并将其包含在

done（）

callback中。

这段代码都是JQuery代码，与php升级到7无关。请出示你的php代码。嗨，阿斯兰，我道歉。我现在已经将我的php代码添加到问题中。

mysql.*

函数已被弃用。使用

mysqli.*

或PDO，谢谢。我发现我不能简单地用mysqli替换mysql。你知道有什么工具可以帮助我正确地转换它吗？

mysql.*

函数实际上从7.*开始就被完全删除了，之前已经有几个版本不推荐使用了。
