在php中将用户重定向到同一页面问题

我正在用php创建一个博客，mysql（PDO）。在博客中，我创建了这样一种逻辑，当新用户出现时，它将首先登录，然后他/她将能够看到帖子和评论。现在我在评论部分遇到了一个问题。。。 我创建了一个评论表，每个用户的评论都将保存在该表中，当管理员批准该评论时，该评论将显示在Concernd页面上

主要问题：

当用户评论页面重新加载时，我收到一些通知，我知道通知的原因，原因是当用户单击帖子查看其详细内容时，帖子将代表Id打开，但当用户评论帖子并重新加载页面时，页面无法找到相关的帖子Id，它会显示通知

这是我的评论表图片

这是我的贴页代码……

首先尝试此注释部分获取图像id

 <form action="comment.php" method="post" class="col-md-12" id="commentForm">
                <textarea name="comment" id="" cols="100" rows="5" placeholder="Your comment"></textarea>

                <input type="hidden" name="image-id" value="<?php echo '?id='.$pic_id;?>"/>
                <br/>
                <input type="submit" value="Post" name="cmsg" id="" class="btn btn-info"/>
                <br/>
            </form>

注意根据需要管理您的代码，我只为您提供重定向解决方案。上面的代码对我来说很好…
请注意您的代码容易受到SQL注入的攻击。另外，请注意不要受到XSS的攻击。ad 2您需要添加where Status=“accepted“要查询ad 3，请尝试打印变量$rows，检查执行函数的状态。”
