这是我的代码：

 <?php
    if(!isset($_COOKIE['loggedin'])){
        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']; 
?>
<html>
    <head>
        <title>Details</title>
    </head>

<body>
<table width="1000" border="2" align="center" bgcolor="pink"> 
    <tr>
        <td colspan="10" align="center" bgcolor="yellow"><h1>View All Details</h1></td>
    </tr>

    <tr bgcolor="orange">
        <th>ID</th>
        <th>Username</th>
        <th>Password</th>
        <th>Name</th>
        <th>Address</th>
    </tr>
<tr align="center">
        <td><?php echo $id; ?></td>
        <td><?php echo $username; ?></td>
        <td><?php echo $password; ?></td>
        <td><?php echo $name; ?></td>
        <td><?php echo $address; ?></td>


    </tr>
<?php } ?>


</table>


</body>
</html>

<?php } ?>

【问题讨论】：

将 $run = mysql_query($query); 更改为 $run = mysql_query($query) or die(mysql_error); 以便它可以为您提供错误的输出并发布它。请使用mysql_fetch_assoc 而不是mysql_fetch_array。
执行此操作后出现同样的错误@OrelEraki
你的 $password 和 $username 在连接到 db 后会被覆盖，我不知道t think thats 的问题，但你应该选择其他名称。
@user3023297, 你能在每个 mysql..() 命令之后加上or die(mysql_error())。并请分享输出。（我忘记在第一条评论中使用括号）。
我已经放了$run = (mysql_query($query) or die(mysql_error));，但现在它给了我这个错误Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\mysql_login\user_details.php on line 30@OrelEraki

标签： mysql profile

【解决方案1】：

知道了，你还没有连接到我认为的数据库。应该是

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

试试这个应该可以，因为我今天刚做了个人资料页面。

希望对你有帮助

呸

【讨论】：

在这样做之后，它给了我这些错误Warning: mysql_query() expects parameter 2 to be resource, string given in C:\xampp\htdocs\mysql_login\user_details.php on line 28Warning: mysql_fetch_assoc() expects parameter 1 to be resource, null given in C:\xampp\htdocs\mysql_login\user_details.php on line 30
你的mysql数据库里有数据吗？
是的，我的数据库中有数据数据库：登录表：用户，它有 id、用户名、密码、名称、地址

【解决方案2】：

首先这不是通知错误，它是在您使用 WAMP 软件时产生的。要么只定义变量

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

或关闭通知；希望它会帮助你。 :)

【讨论】：

你有没有在循环之前添加这些变量；
