Question

在我说什么之前我会发布我的index.php，让大家先了解一下它的样子：

<script>
function submitLikeForm()  {
var form = jQuery("#like_form");
    $.ajax({ type: "GET", url: form.attr("action"), data: form.serialize(), success:    function() });
}
</script>

<script>
function leaveYourComment()  {
var form = jQuery("#comment_form");
    $.ajax({ type: "GET", url: form.attr("action"), data: form.serialize(), success: function() });
}
</script>

<link type="text/css" rel="stylesheet" href="index.css">

</head>

<body>

好的，所以基本上，所以这个index.php页面是用户上传后的图片。用户可以评论并喜欢帖子/图片。

我遇到的问题是我的评论系统。评论上传到mysqli很好，但是，我很难回应每个评论。我的表格中显示了多条评论，但是当我发布新评论时，新评论只会替换之前发布的评论。我不想要这个，我希望每个评论都显示在id DESC。

我已经为评论尝试了一个循环（正如您在上面的代码中看到的那样），但就像我说的那样，它只会使最新的评论取代旧的评论。

那么我该如何更正我的代码，以便所有评论都显示在comment_box中的comment_box_wrapper内，以及发布评论的用户的相应信息。

我整天都在挣扎，所以任何帮助都会受到赞赏。

如果您需要我发布任何其他内容，请告诉我。我只发布了index.php，因为其他一切正常，问题只出现在这个页面上。

您在循环中分配$ comment和$ commented_by变量，有效地覆盖它们，而不使用它们。

您需要将一个大echo拆分，并将comment_box部分替换为以下内容：

while($comment_result = mysqli_fetch_assoc($comment_query)) {
  echo "<div class='comment_box'>";
    echo "<div class='commenter'>".$comment_result['commenting_user']."</div>";
    echo "<div class='profile_pic'><img src='https://i.imgur.com/1MkFvhU.png'></div>";
    echo "<div class='actual_comment custom_scrollbar'>".$comment_result['comment']."</div>";
  echo "</div>";
}

如上所述，我们在循环的每次迭代中打印每个评论数据。

回应表中的所有评论
