使用php mysql ajax jquery为好友系统创建接受或拒绝操作

我有一个朋友请求系统，允许用户向其他人发送请求，我有一个接受或拒绝按钮。但是问题是代码中有一些东西没有被写入，使得系统没有显示任何内容，我不知道错误在哪里 有人能帮我吗

这是ajax部分 php代码：

我认为您的代码中有错误：

函数{data}{}应该是函数数据{}

您收到了什么样的错误消息？php没有执行吗？您是否收到javascript错误检查您的错误控制台？仅仅发布您的代码并要求人们查找bug似乎不适合此网站。可能所有这些查询都不会返回任何行或一行。。。使用while循环获取这些0/1行是cargo cult编程的一个主要症状。你真的需要学习数据库规范化，这将把你的整个代码堆减少到只有两个查询和5-6行代码…先生，这是我试图建立的第一个网站，在开发周期内，我将从像你这样的人那里获得未来的丰富经验
