php - 如何给php网站添加评论区

Question

嘿伙计们，我有一个网站，其网址如下所示: www.domain.com/photos.php?id=(图片ID); 现在，我的问题是，如何使用 mysql 和 php 为每张图片添加注释。

Answer 1

您可能需要一个新表来将用户与评论与图片链接起来:

表格: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，再次查询任何评论:

$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评论:

$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']);
}
