【问题描述】：
请帮助找到我的代码问题的根源...当我单击请求时，页面会刷新，所有数据都消失了，但没有任何内容插入到数据库中... 这是数据库的图像和代码！我需要更改什么才能将数据与登录用户的用户名一起插入？ ![数据库]http://imgur.com/t0DrlHH
@user1151316 我进行了更改，这里是删除无意义 cmets 的代码...数据没有被插入，提交后我得到一个空白屏幕...
<?php
//require_once 'includes/dbconnect.php';
session_start();
if (isset($_POST["request"]))
{
//print_r($_POST);die;
//take care of injections
$service = mysqli_real_escape_string($link,$_POST['service']);
$service_details = mysqli_real_escape_string($link,$_POST['service_details']);
$duedate = mysqli_real_escape_string($link,$_POST['duedate']);
$postdate = mysqli_real_escape_string($link,$_POST['postdate']); //READ ONLY DATE POST
// Insert data into mysql + LOGGED IN USERS USERNAME TO BE INSERTED
$sql = "INSERT INTO serviceposts VALUES ('".$_SESSION["username"]."','".$service."', '".$service_details."', '".$duedate."', '".$postdate."')";
$result= $link -> query($sql) or die (mysqli_error($link));
echo "($result)";
// if successfully insert data into database, displays message "Successful".
if($result){
echo "request post success!";
echo'<script>window.location="http://localhost/Project2/User.php#viewrequests";</script>';
}
else {
echo "Possible data input error";
}
$link->close();
}
?>

【问题讨论】：
-
您在浏览器的控制台中查看过请求/响应吗？你检查过错误日志吗？
-
你调用 session_start() 之后你已经在使用会话变量，并且你没有名为
request的表单字段，所以$_POST['request']永远不会被设置，跳过你所有的数据库代码。 -
虽然这似乎与 jQuery 没有任何关系，但你为什么要包含这么多不同版本的它（和 jQuery UI）？
-
嘿 blanchard...我是 php 和 jquery 的初学者，我正在使用 xampp，而且错误日志不是很容易访问，尤其是对于像我这样的人...另外我有一个 migrane，我只想插入数据...我尝试在 echo "($result)" 之前回显错误（如果有）；线，但我什么也没得到......

Marc B...感谢您的指点...“请求”指的是提交按钮...
