如何向php网站添加评论部分

嘿，伙计们，我有一个网站的url看起来有点像这样： www.domain.com/photos.php？id=（图像id）；

---

现在，我的问题是，如何使用mysql和php向每张图片添加注释

您可能需要一个新表来链接用户和带有图片的注释：

表：评论

id (comment id), user (user id), picture (pic id), comment (text), date(timestamp w/default current time)

然后在显示图像后，对任何注释执行另一个查询：

$comments_query = mysql_query("SELECT comment FROM comments WHERE picture = $id");
while($comments_result = mysql_fetch_array($comments_query)){
   echo($comments_result['comment']);
}

---

您可能还希望将每个用户的用户名链接到注释：

$comments_query = mysql_query("SELECT comments.comment, users.username, comments.date FROM comments INNER JOIN users ON comments.user = users.id WHERE comments.picture = $id");
while($comments_result = mysql_fetch_array($comments_query)){
    echo($comments_result['date']);
    echo($comments_result['username']);       
    echo($comments_result['comment']);
}

评论是来自用户还是每张图片一条评论？评论是来自用户还是每张图片一条评论？
