因为我是ajax的新手并且对此不太了解...我创建了2个php文件，其中一个是 six.php ，另一个是 six-cuf.php ... 根据six.php中的用户输入和点击提交，这将调用六个cuf。 php使用ajax并进行计算。
但是，当我通过chrome中的网络选项卡执行并监视代码时，我知道这些值被传递给了6-cuf.php，但是它没有进入页面内部的if条件它没有得到任何回应。
它没有进入if（）在上面的代码中开始的六个cuf.php是什么错误
当我使用json_decode时它返回null所以使用json_last_erro并返回以下错误消息....语法错误，格式错误的JSON
Six.php

由于您使用过json，因此需要使用 six-cuf.php 上的json_decode解码参数。这里看一下php's tutorial for json_decode

你说你的第一个陈述有问题 - 你是对的。
if(isset($_POST["dateipone"],$_POST["dateiptwo"],$_POST["ino"], $_POST["options"],$_POST["dateone"],$_POST["datetwo"],$_POST["submit"]))
您需要检查是否为每个变量设置了变量。
将其更改为：
if(isset($_POST["dateipone"]) && isset($_POST["dateiptwo"]) && isset($_POST["ino"]) && isset($_POST["options"]) && isset($_POST["dateone"]) && isset($_POST["datetwo"]) && isset($_POST["submit"]))
