Question

出于某种原因，这不起作用，但不确定原因。我正在尝试获取有关数据库中有多少条评论的评论ID，但它显示为“0”。当我清楚地看到评论时。

直播：http://www.krissales.me/#/media/articles

如果您点击文章链接，它会显示该页面上的评论数量，但不会显示我希望它显示的页面上的评论。

我很确定它与以下内容有关：

$ amount_get = mysql_query（“SELECT * FROM comment WHERE id ='”。 mysql_real_escape_string（$ _ GET ['id']）。 “'”）; $ comments = mysql_num_rows（$ amount_get）;

article.php：

<?php

        $amount_get = mysql_query("SELECT * FROM comment WHERE id='" . mysql_real_escape_string($_GET['id']) . "'"); 
        $comments = mysql_num_rows($amount_get);            

        $grab = mysql_query("SELECT * FROM articles WHERE id='" . mysql_real_escape_string($_GET['id']) . "' LIMIT 1");    
        $grab = mysql_query("SELECT id, news_title, news_content, news_author, news_day, news_month, news_year, news_date FROM articles ORDER BY id DESC limit 3"); 
        $news_day =$row['news_day'];
        $news_month =$row['news_month'];
        $news_year =$row['news_year'];


        if (mysql_num_rows($grab)==0) {
        echo "<div class='alert alert-note-x'>Sorry, it looks like their are no articles posted!</div>";
    }
        while($row = mysql_fetch_array($grab)){

    ?>

    <div class="post-container">
        <div class="post">
        <div class="left">
        <div class="date"><span class="day"><?php echo $row['news_day'] ?></span> <span class="month"><?php echo $row['news_month'] ?></span> <span class="year"><?php echo $row['news_year'] ?></span></div></div>
        <div class="postcontent"><h5 class="posttitle"><a href="#/media/<?php echo $row['id'] ?>.<?php echo stripslashes(str_replace(" ", "-", $row['news_title'])); ?>"><?php echo stripslashes($row['news_title']); ?></a></h5>                       
            <p>The content for this article will be posted here shortly, i need to edit some PHP that limits the chars for this section</p>
            <p>Comments (<?php echo $comments ?>)</p>
            </div>
    </div>
    </div>  

  <?php } ?>

您应该查看此行的WHERE条件：

$amount_get = mysql_query("SELECT * FROM comment WHERE id='" . mysql_real_escape_string($_GET['id']) . "'");

我想id应该更改为article_id - 指向文章的foreign_key。
