Question

我有一个脚本来回复发送邮件的用户，当我使用回复脚本时，它没有在数据库中存储任何名称。

以下是为回复设置会话的查看脚本。

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


  while ($row = mysqli_fetch_array($data)) {
    $_SESSION['reply'] = $row['from'];
        $username2 = $_SESSION['reply'];
  echo '<div class="viewpost">';
  echo '<div class="vpside">';
    if(!empty($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>';
    }

然后回复的脚本：

  if (isset($_POST['submit'])) {
        $username2 = $_SESSION['reply'];
    // Grab the profile data from the POST
     $msg = mysqli_real_escape_string($dbc, strip_tags( trim($_POST['msg'])));
     $title = mysqli_real_escape_string($dbc, trim($_POST['title']));
     $to = $username2;

    // Update the post data in the database
      if (!empty($msg) && !empty($title)) {
        // Only set the picture column if there is a new picture
    $query = "INSERT INTO kaoscraft_pm (`from`, `to`, `rank`, `gender`, `picture`, `msg_date`, `title`, `msg`) VALUES ('$username', '$to', '$rank', '$gender', '$picture', NOW(), '$title', '$msg')";
        mysqli_query($dbc, $query);

Answer 1

您正在定义$username2，但在查询中使用$username。

Answer 2

正如@albxn所说，

由于sqlquery中有'from'

，因此不会填充

$username

但是，您正试图从'to'

填充$_SESSION['reply'];

你没有session_start()

回复脚本不在数据库中存储名称
