HomeBackend DevelopmentPHP Tutorial写了一个简单留言板发布代码,但总是无法把留言录入MySQL数据库中,求大神指点错误!

    我初学php和mysql,模仿php100视频教程做一个留言板发布网站,但点击“留言“按钮后总是弹出“留言失败!”,同时数据库中也没有导入信息,求大神看一下哪出代码出问题了,谢谢!
     数据库 名称:test_liuyanban
     表 名称:message
     字段:int(主键)、username(用户名)、email(邮箱)、content(留言内容)。
     一共两个文件:conn.php和index.php
     conn.php:
$conn = @mysql_connect('localhost','root','12345')or die('连接失败!');
@mysql_select_db("test_liuyanban")or die('没有该数据库!');
mysql_query("set names 'GBK'");
?>
     
     index.php:
include_once'conn.php';
if($_POST['post']){
    $sql="insert into `message` (id,username,email,content) values ('','$_POST[username]','$_POST[email]','$_POST[content]')";
    $result=mysql_query($sql);
    if($result){
        echo"<script>alert('留言成功!');location.href='index.php'</script>";
    }else{
        echo"<script>alert('留言失败!');location.href='index.php'</script>";
    }
}
?>




    

        
        
            
            
        
        
            
            
        
        
            
            
        
        
        
        
    




回复讨论(解决方案)

$sql="insert into `message` (id,username,email,content) values ('',$_POST['username'],$_POST['email'],$_POST['content'])";

$sql="insert into `message` (id,username,email,content) values ('',$_POST['username'],$_POST['email'],$_POST['content'])";

按照这个方法试了下,网页无法正常显示,没改前浏览器还能看到这个

$result=mysql_query($sql) or die(mysql_error());  这样有报错没

$result=mysql_query($sql) or die(mysql_error());  这样有报错没
加入了你说的代码,点击“回复”后浏览器显示这个




怎么解决?谢谢指导

说错了,是点击“留言”

你的表中没有email 字段,show create table message; 看看

找到答案了,我犯了个低级错误,把数据库里的字段名“email”打成了“emai”,哈哈

What is a session in PHP, and why are they used?What is a session in PHP, and why are they used?May 04, 2025 am 12:12 AM

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

What is the difference between absolute and idle session timeouts?What is the difference between absolute and idle session timeouts?May 03, 2025 am 12:21 AM

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

What steps would you take if sessions aren't working on your server?What steps would you take if sessions aren't working on your server?May 03, 2025 am 12:19 AM

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
