Javascript 更新emp信息mysql查询不起作用

尝试使用员工id（emp_id）更新员工信息

我已经在下面编写了更新查询。我已经检查了表名和 数据库详细信息均正确，但由于某些原因，更新查询不正确 跑步

有没有办法解决这个问题

<?php

session_start();
$id=$_SESSION['SESS_MEMBER_ID'];
//echo $id;
require_once('auth.php');
include('connection.php');
?>

<?php
$query2="SELECT * FROM add_employee where emp_id='$id'";
$result1=mysqli_query($conn, $query2);
while($row=mysqli_fetch_array($result1))
{ 
   fullname=$row['fullname'];
   $email=$row['email'];
   $contact=$row['contact'];
   $address=$row['address'];
   $designation=$row['designation'];
   //$client_name=$row['client_name'];
   $joining_date=$row['joining_date'];
   $password=$row['password'];
   //$aadhartoupload=$row['aadhar'];
   $filetoupload=$row['photo'];
   //$resumetoupload=$row['resume'];
}
//die();
?>

获取员工信息

<?php
if(isset($_POST['submit'])){            
   $fullname=$_POST['fullname'];
   $email=$_POST['email'];
   $contact=$_POST['contact'];
   $address=$_POST['address'];
   $designation=$_POST['designation'];
   //$client_name=$_POST['client_name'];
   $joining_date=$_POST['joining_date'];
   $password=$_POST['password'];

我认为您需要检查
附近的sql语句，其中emp_id=$id
。尝试使用
而不是emp_id='$id'
。这些引号可能会有所不同。
嗨，Rohit。欢迎来到StackOverflow！。您是否可以包含任何错误消息？1）您的代码容易受到sql注入攻击，如果任何输入字段包含一个引号，那么它将关闭您的查询2）我看不到任何可以用来更新数据的表单3）$id来自何方？嗨，Ahmad，感谢您的回复，提交表单后，我没有收到任何错误消息。我只收到警报（“未成功-错误！”）嗨，Shadow，谢谢你的即时回复，我已在问题中添加了表单，请检查。好，在else分支中，您可以打印出实际的错误消息，这样您就知道发生了什么。鼓励使用字符串插值而不试图阻止sql注入是一个非常糟糕的建议@Shadow，我也是新来的，所以我认为应该有人对准备好的语句不感兴趣，而是想知道是什么阻止了他们的代码运行。我想你不感兴趣或者只是不知道？好的，注意到了。在future@Twista谢谢你的帮助这对我很有用：）
