Question

我在做博客网页。用户可以在博客上发布他们的状态，因此在用户个人资料页面上，用户可以查看他们发布的内容。

我遇到了关于分开的帖子部分和评论部分的问题。我想要的是显示带有帖子部分的评论部分。评论部分根据帖子部分显示。

示例：像facebook一样，我在该帖子上发布状态和其他用户评论。

Img 1如下：

在图1中，您可以看到根据帖子部分不显示评论部分。

Img 2如下：

这就是我想要做的例子。

PHP＆amp; HTML代码如下：

<div class="feed-card">
$postSql = "SELECT user.firstname, user.lastname, user.profile_photo, post.id ,post.post_contain, post.post_image, post.timestamp 
            FROM user

            ON user.id = post.user_id
            WHERE user.id = '".$u_id."' 
            ORDER BY post.timestamp 
            DESC";

if ($postStmt = $conn->prepare($postSql)) {
    /* execute query */
    $postStmt->execute();

    $postStmt->bind_result($user_firstname, $user_lastname, $user_profile_photo, $post_id, $post_content, $post_image, $post_timestamp);

    $postIdArray = array();
    while ($postStmt->fetch()) {

不是收集数组中的所有帖子ID，然后为每个帖子获取评论，而是在显示帖子时获取每个帖子的评论。我无法测试代码，但这应该可行。

        <div class="feed-card">

        <?php 
    $postSql = "SELECT user.firstname, user.lastname, user.profile_photo, post.id ,post.post_contain, post.post_image, post.timestamp 
                FROM user 
                INNER JOIN post 
                ON user.id = post.user_id
                WHERE user.id = '".$u_id."' 
                ORDER BY post.timestamp 
                DESC";

    if ($postStmt = $conn->prepare($postSql)) {
        /* execute query */
        $postStmt->execute();

        $postStmt->bind_result($user_firstname, $user_lastname, $user_profile_photo, $post_id, $post_content, $post_image, $post_timestamp);
