How to show comments under a post like facebook does?

本文关键字：评论显示一样何像脸 | 更新日期: 2023-09-27

我正在尝试制作一个类似于facebook墙的php脚本。

它从我的MySQL数据库中加载帖子、照片url和用户信息，比如用户名和用户id。它还检查该帖子是否只是对另一个帖子（parentof）的评论。我可以在使用标签的同时，通过简单的操作将所有原始帖子与图片一起呈现。

但我怎么能在每一篇帖子下面都发表评论呢？我想是用另一个循环，但怎么做呢？

这是我的代码：

<?php
require_once "config.php";
    $result = mysql_query('SET NAMES utf8');
    $result = mysql_query('SET CHARACTER SET utf8');
    $wallhaku = mysql_query("SELECT `wall`.`post_id`, `wall`.`parentof`, `wall`.`sentby`, `wall`.`text`, `wall`.`image_url`, `users`.`username`, `users`.`photopath`, `users`.`name`, `users`.`member_id` FROM `wall` LEFT JOIN `users` ON `wall`.`sentby` = `users`.`member_id` WHERE parentof=0 ORDER BY post_id DESC") or die (mysql_error());
    $row_wallhaku = mysql_fetch_array($wallhaku);

<table width="800" height="120" border="0" cellpadding="10">
<?php $i=0; $numberpage=1;
    do {
    $wallid = $row_wallhaku['post_id'];
    $parenthaku = mysql_query("SELECT post_id, parentof FROM wall WHERE parentof=$wallid") or die (mysql_error());
    $row_parenthaku = mysql_num_rows($parenthaku);
      <td width="120" align="left">
      <img src=<?php echo $row_wallhaku['photopath']; ?> height=    "100" width="100">
      </td>
      <td width="600" align="left">
    <a href="member.php?id=<?php echo $row_wallhaku['member_id']; ?>"><?php echo $row_wallhaku['name']?></a><br /><p><?php echo $row_wallhaku['text'];
    if($row_wallhaku['image_url']=="0") {
    <p align="right"><?php echo $row_parenthaku ?> kommenttia.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<a href="post.php?id=<?php echo $row_wallhaku['post_id']; ?>">Lue, kommentoi</a> <?php } ?></td>
<?php $i++; if($i%$numberpage==0) echo "</tr>";
if($row_wallhaku['image_url']!="0")
    {
    <tr>
    <td width='800' colspan='2' align='center'>
    <a href="post.php?id=<?php echo $row_wallhaku['post_id']; ?>"><img src=<?php echo $row_wallhaku['image_url']; ?> height="180"></a>
    <p align="right"><?php echo $row_parenthaku ?> kommenttia.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<a href="post.php?id=<?php echo $row_wallhaku['post_id']; ?>">Lue, kommentoi</a>
    </td>
    </tr>
    <?php
    }
</table>

如果帖子之间的关系是一对多，则需要使用2个查询。第一个查询将获得主题（帖子）的数据。另一个查询将获得"parentof"等于主题id的所有评论的数据。

$id = $_GET['id'];
$getTopic = mysql_query("SELECT * FROM posts WHERE id='$id'");
$topic = mysql_fetch_array($getTopic);
$getComments = mysql_query("SELECT * FROM posts WHERE parentOf='{$topic['id']}'");
while($comment = mysql_fetch_array($getComments))
{
 echo $comment['title']; //You should use a "view" functin which handles the HTML and staff.
}
