抓文章ID帖子

Question

出於某種原因，這是行不通的，但不知道爲什麼。我試圖抓住關於數據庫中有多少評論的評論ID，但它顯示「0」。當我清楚地看到評論。

訪問過：http://www.krissales.me/#/media/articles

如果單擊文章鏈接，它會告訴我要多少意見在該網頁上，而不是在頁面上展示上。

我敢肯定，它有什麼做的：

$ amount_get =請求mysql_query（ 「SELECT * FROM評論WHERE ID ='」。 mysql_real_escape_string（$ _ GET [ '身份證']） 。「'」）; $ 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 } ?>

你應該看看這行的WHERE條件：

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

我想這應該id被更改爲類似article_id - 一個foreign_key指向一篇文章。
