Question

当我点击帖子按钮时，评论会在页面上发布。如果我再次点击它，它会覆盖之前的评论。有人可以澄清一下吗？我正在运行java脚本来显示日期。它一直显示没有任何评论。我怎么能修改它呢？提前谢谢！

Answer 1

你真的是这个意思吗？ '您的电子邮件地址不会被公开。'您将所有“邮件地址”写入明文文件以便大声喊叫。不要把它放在网上。

Answer 2

您没有回读文件来绘制评论，您只是使用了来自的POST数据：

<div>
    <strong><?php 
     $name = $_POST['author'];
     echo $name; ?> </strong> <small><script type="text/javascript">
     var d = new Date()
     document.write(d.getDate())
     document.write("/")
     document.write(d.getMonth() + 1)
     document.write("/")
     document.write(d.getFullYear())
 </script>
 </small>
</div>
<div>
 <p><?php
 $comment = $_POST['comment'];
 echo "\n".$comment."\n"."<hr>";
 ?></p></div>
 </div></div>
</div>

PHP中的

$_POST指的是脚本响应的POST请求的主体。

您需要将其替换为执行以下三项操作的功能：

从文件中读取。
使用author和comment
迭代这些条目并为每条记录绘制一个单独的div。

另一个问题：您的代码正在将当前日期打印为评论的日期。如果您没有存储评论的日期，则可能不应显示日期。

$comment = $_POST['comment'];

$data_post->name = $name;
$data_post->comment = $comment;

if(isset($name, $comment)){
    header('Content-type: application/json');
    echo(json_encode($data_post));
    return;

不要忘记使用php文件名更改ajax帖子中的网址（第26行）

评论框中的评论是重写，而不是发布
