我有一个关于从数据库中检索数据的问题。我在userrecord中创建了一个数据库,其表名是tbl_user。我试图在他们登录系统时显示用户信息。即查看记录的用户配置文件代码如下:
<?php
include("auth_user.inc.php"); // authrization page
$uname=$_SESSION['user']; // logged user name
$connection=mysql_connect("localhost","root"," ");
mysql_select_db("userrecord",$connection);
$sql=("select * from table_user where uname ='$uname'");
$result=@mysql_query($sql,$connection);
$row=mysql_fetch_array($result);
?>
<html>
<head>
<title>User Account</title>
</head>
<body bgcolor="#33CCFF">
<br>Your Details Information Is Shown Below:<br><br>
First Name:<?php echo $row['fname'];?><br>
Last Name:<?php echo $row['lname'];?><br>
Address:<?php echo $row['address'];?><br>
E-Mail:<?php echo $row['email'];?><br>
Gender:<?php echo $row['fname'];?><br>
User Name:<?php echo $row['uname'];?><br>
</body>
</html>
代码echo $ row ['']不显示数据库中的记录。

,其表名为 tbl_user
你的SQL是table_user
?
无论如何,我没有看到其他人误以为你的代码,就是这样。如果是拼写错误,请尝试调试连接,并向我们提供错误消息...

尝试:
<?php
include("auth_user.inc.php"); // authrization page
$uname = $_SESSION['user']; // logged user name
$connection = mysql_connect("localhost","root"," ") or die('Could not connect to database: '.mysql_error());
mysql_select_db("userrecord",$connection) or die('Could select database: '.mysql_error());
$sql = "select * from table_user where uname ='$uname'";
$result = mysql_query($sql) or die ('Mysql error: '.mysql_error.' - '.mysql_errno());
$row = mysql_fetch_array($result);
?>

不需要这个@符号:
$result=@mysql_query($sql,$connection);
校正:
$result=mysql_query($sql,$connection);
