        header("location:index.php");
    }

session_start();

if(!isset($_SESSION['user'])){

header("location: index.php");
}
else {

?>


<?php
$username = "root";
    $password = "123";
    $hostname = "localhost";

    $dbhandle = mysql_connect($hostname, $username, $password) or die("Could not connect to database");

    $selected = mysql_select_db("login", $dbhandle);

$query = "select * from users";

$run = (mysql_query($query) or die(mysql_error));

while($row=mysql_fetch_assoc($run)){

    $id = $row['id'];
    $username = $row['username'];
    $password = $row['password'];
    $name = $row['name'];
    $address = $row['address'];

Answer 1

知道了，你还没有连接到我想要的数据库。它应该是

 $run = mysql_query($selected,$query);

试试这个应该可行，因为我今天刚刚制作了一个个人资料页面。

希望有所帮助

Answer 2

首先，这不是它注意到的错误，它是在你使用WAMP软件时产生的。或者只是定义变量

$id = '';
$username ='';
$password = '';
$name = '';
$address=''; 
before while loop

或关闭通知;希望它会对你有所帮助。：）

用户个人资料未显示其数据
