如何将评论与postid与该邮件的帖子绑定?
这是一场真正的斗争。我一直试图调试1小时的更好的一部分,但我找不到任何解决方案。我正在制作一个与博客帖子关联的评论系统。当您发表评论时,您将返回到相同的帖子。帖子页面根据postid动态填充。评论是使用相同的postid添加的,所以他们只填写他们的相关帖子。我查询评论是错误的,但我没有得到如何。如何将评论与postid与该邮件的帖子绑定?

代码:
<?php require("connect.php");
$postid = $_GET['id'];
if(isset($_POST['postcomment'])){
$comment = $_POST['comment'];
$author = $_SESSION['username'];
$commentQuery = mysqli_query($conn, "INSERT INTO comments (com_content, com_timestamp, com_author, com_postid) VALUES ('$comment', now(), '$author', '$postid')");
if($commentQuery){
header('Location: postpage.php?id='.$postid);
}
}
?>

<div class="comment-new-wrapper">
<form class="flex-enable flex-column" method="POST">

<input class="comment-button small-white-subtitle" type="submit" name="postcomment" value="Post Comment">
</form>
</div>
</div>
<?php
$summonComm = "SELECT * FROM comments WHERE com_postid='".$postid."' ORDER BY id DESC";
$resultComm = mysqli_query($conn, $summonComm);
while ($row = mysqli_fetch_array($resultComm)){
$comment= $row['com_content'];
$timestamp= $row['timestamp'];
$author= $row['com_author'];
?>
<span class="blog-timestamp"><?php echo $timestamp; ?> • Written by <a href="<?php echo $author; ?>.php"><?php echo $author; ?></a></span>
<span class="blog-entry"><?php echo $comment; ?></span>
</div>
<?php
}
?>
回答:
ORDER BY id DESC
不工作,因为我的数据库字段被称为 “com_postid”。 $timestamp = $row['timestamp']
不起作用,因为我的db字段被称为“com_timestamp”。
