php没有传递$id来查询
我正在尝试使用从mysqli查询中提取的数据执行内联编辑脚本，该查询使用if isset ?id= $_GET基于url $id提取特定数据，页面正在获取并正确回显id，但是，查询未获取$id变量。
我已经通过将$id var替换为相对于数据的数字来测试查询，并且它可以正常工作。
我尝试将$id添加到$_SESSION并从那里取回它但仍然没有运气。
主页是index.php（其中包含index.php?id=2019018的url），它通过js（fetch_data.php）获取数据并将其显示为具有内联编辑功能的数据网格。
您可能会注意到已经注释掉的测试等
两个脚本都在下面，任何帮助赞赏

您需要将id传递给您的AJAX请求，因为它被视为完全独立的请求。
EG
insertItem: function (item) {
return $.ajax({
type: "POST",
url: "fetch_data.php?id="<?php echo $id; ?>,
data: item
});
},
