Question

出于某种原因，我正在尝试创建的表格未显示在我的页面上。页面使用完美，我无法弄清楚为什么它现在不起作用。

我的程序仅在我设置

时有效

$_SESSION['loginname']="jordan@yahoo.com"; 
or $_SESSION['loginname']="mary666@yahoo.com";

等等。

我已经在我的上一页上创建了一个名为$_SESSION['loginname'];的“$ _Session”我一遍又一遍地回应会话，看看它是否正在从一个页面传递到另一个页面当前页面确实如此。

为什么我的$ _SESSION不允许我的MYSQL代码运行循环来显示我的数据库中的数据？代码如下：

<?php
session_start();
?>
<!DOCTYPE html> 
<html>

<head>
  <title>User Account</title>

  <link rel="stylesheet" type="text/css" href="css/style.css" /> 
</head>

<body>
  <div id="main">

    <header>
      <div id="welcome">
        <h2>Prairie View A&amp;M University</h2>
      </div><!--close welcome-->                
    </header>   

    <nav>
      <div id="menubar">
        <ul id="nav">
          <li><a href="index.php">Home</a></li>
          <li class="current"><a href="user-account.php">Account Info</a></li>
          <li><a href="quiz_main.php">Quiz</a></li>
          &nbsp &nbsp &nbsp &nbsp &nbsp
<?php
if($_SESSION['loginname'])
echo $_SESSION['loginname'].", "."<a href='user-account.php'>Account</a>"."     "."<a href='logout.php'>Logout</a>";

else
    die("You must login");
?>
        </ul>
      </div><!--close menubar-->    
    </nav>      

    <div id="site_content">

   <?php
$username = "root";
$password = "";
$hostname = "localhost";
$database = "basketball_database";
$table = "users";

$session_login = $_SESSION['loginname'];

$con = mysql_connect($hostname, $username, $password)
 or die("Unable to connect to MYsql");
// echo "Connected to mysql<br>";

 mysql_select_db("$database")
 or die("Could not select Basketball_database");
 //echo "Connected to database";

 $mysql = "SELECT * FROM $table WHERE login_name='$_SESSION[loginname]'";


 $mydata = mysql_query($mysql,$con);

 while($records = mysql_fetch_array($mydata)){
 //create table
 echo "<table border=1
 <tr>
 <th>User ID</th></tr>
 <tr>
 <th>Login Name</th></tr>
 <tr>
 <th>Password</th></tr>
 <tr>
 <th>Last Name</th></tr>
 <tr>
 <th>First Name</th></tr>
 <tr>
 <th>Account Type</th>
 </tr>";



     echo "<tr>";
     echo "<td>".$records['user_ID']."</td>";
     echo "<td>".$records['login_name']."</td>";
     echo "<td>".$records['password']."</td>";
     echo "<td>".$records['last_name']."</td>";
     echo "<td>".$records['first_name']."</td>";
     echo "<td>".$records['type']."</td>";
     echo "</tr>";       
 } echo "</table>";

 mysql_close();
?>

      <div id="content">
        <div class="content_item">


      </div><!--close content_container-->          
    </div><!--close content_item-->
</div><!--close content-->   
    </div><!--close site_content-->     

    <footer>
     <a href="index.php">Home</a> | <a href="photos.php">Photos</a> | <a href="videos.php">Videos</a> | <a href="schedule.php">Schedule</a> | <a href="contact.php">Contact</a><br/><br/>

    </footer>   

  </div><!--close main-->

  <!-- javascript at the bottom for fast page loading -->
  <script type="text/javascript" src="js/jquery.min.js"></script>
  <script type="text/javascript" src="js/image_slide.js"></script>  

</body>
</html>

我意识到我的桌子看起来像这样

User ID
Login Name
Password
Last Name
First Name
Account Type
1321  jordan@yahoo.com  21duncan   oneal  jordan   athlete

表格不会显示，Sql也不会运行
