<p>What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a
type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and
more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>

因为你发送了一个“发布”请求，所以永远不会处理你必须用“GET”方法发送它看到这可能有帮助
('#add').click(function(){
var u = `"<?php echo $u->id?>"` <--- this is friend id
var id = "<?php echo $_SESSION['user']";?> <---- this is my id
$.ajax({
type: "GET",
url : "?u="+u+"&add="+id,
success: function(data){//here the function should have a parameter which is the response of your request
alert(data);//try to debug it and see what is the response or alert("success")
}
在你的php文件中，你只需使用即可获得这些参数
$_GET["u"]和$_GET["add"]在您的插入请求中使用它们

使用引号arround php tag
var u = "<?php echo $u->id;?>";
var id = "<?php echo $_SESSION['user'];?>";
此处也更改删除额外的单引号。
url: "?u="+u+"&add="+id,
