会话不使用正确的变量

我有一个会话应该从一个页面到另一个页面携带一个变量。会话已设置,但它没有正确的值,我需要此会话动态更改。 以下是查看页面的代码:

  // Connect to the database
  $dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);

      $query = "SELECT username FROM kaoscraft_user WHERE user_id = '" . $_SESSION['user_id'] . "'";
        $data = mysqli_query($dbc, $query);
            $row = mysqli_fetch_array($data);
            $username1 = $row['username'];

  // Grab the pm data from the database
  $query = "SELECT `to`, `from`, rank, gender, picture, title, msg FROM kaoscraft_pm WHERE `to` = '$username1' ORDER BY msg_id DESC";
  $data = mysqli_query($dbc, $query);
  $gender = $row['gender'];

  while ($row = mysqli_fetch_array($data)) {
  session_start();
    $reply = $row['from'];
    $_SESSION['reply'] = $row['from'];
  echo '<div class="viewpost">';
  echo '<div class="vpside">';
    if(!empty($row['picture'])) {
    echo '<img class="pictest" src="' . MM_UPLOADPATH . $row['picture'] . '" alt="' . MM_UPLOADPATH . 'nopic.png' . '" />';
    }
  if(!empty($row['from'])) {
      echo '<p>From:<br />' . $row['from'] . '</p>';
      echo '<a href="reply.php">Reply</a>';
    }
  if(!empty($row['rank'])) {
      echo '<p>Rank:<br />' . $row['rank'] . '</p>';
    }
  if(!empty($row['gender'])){
    echo '<p>Gender:<br /> ' . $row['gender'] . '</p>';
  }  
  echo '</div>';

    if(!empty($row['title'])) {
        echo'<h4><u>' .$row['title']. '</u></h4>';
    }
      if(!empty($row['msg'])) {
      echo '<p class="">' . $row['msg'] . '</p>';
    }
        echo '<div class="sig">';
      if(!empty($row['bio'])) {
      echo '<p>' . $row['bio'] . '</p>';
      }
      echo '</div>';
    echo '</div><br />'; 
    }
  mysqli_close($dbc); 
?>

是的,查询已执行,并且设置了row

这是结转脚本:

    if (isset($_SESSION['reply'])) {
    echo 'value=' . $_SESSION['reply'];
    }

请注意,这是一个测试脚本,而不是我将实际使用的脚本,只是在你想知道的情况下。在第二个脚本中,它是一个 SNIPPET 而不是整个代码,这就是为什么你看不到session_start();
