如何在頁面頂部/首頁顯示新評論

我之前使用過一段代碼，但在我的評論框中添加回復系統時，s不起作用。

我使用的代碼是：

$count = mysql_numrows($results); 
$i = 0; 
while ($i < $count){ 

    $qazi_id = mysql_result($results,$i,"qazi_id"); 
    $username = mysql_result($results,$i,"username"); 
    $email = mysql_result($results,$i,"email"); 
    $description = mysql_result($results,$i,"description");  
    $url = mysql_result($results,$i,"url"); 
    $date = mysql_result($results,$i,"date"); 

other code 

$i++;}

這是我與上面的代碼當前註釋結構，無法正常工作，最後的評論首先也是上面的代碼再次連續顯示總評論系統後再次：

$results = mysql_query("SELECT * FROM comments WHERE qazi_id='$tutid' ORDER BY id DESC") or die(mysql_error()); 

$commentNum = mysql_num_rows($results); 

echo' <div class="post-bottom-section"> 
<h2> '.$commentNum.' comments so far (<a href="#post" title="post your own">post your own</a>)</h2> 
<div class="primary"> 
<ol class="commentlist">'; 

$count = mysql_numrows($results); 
$i = 0; 
while ($i < $count){ 

    $qazi_id = mysql_result($results,$i,"qazi_id"); 
    $username = mysql_result($results,$i,"username"); 
    $email = mysql_result($results,$i,"email"); 
    $description = mysql_result($results,$i,"description");  
    $url = mysql_result($results,$i,"url"); 
    $date = mysql_result($results,$i,"date"); 

    //heres our alternating hack 
    if($css != "depth-1"){ $css = "depth-1"; }else{ $css = "thread-alt depth-1"; } 

$q = "SELECT * FROM comments WHERE parent_id = 0"; 
$r = mysql_query($q); 
while($row = mysql_fetch_assoc($r)) // Only main comment 
    { $id = $row['id']; 
    $qazi_id = $row['qazi_id']; 
    $username = $row['username']; 
    $email = $row['email']; 
    $description = $row['description'];  
    $url = $row['url']; 
    $parent_id = $row['parent_id']; 
    $date = $row['date']; 
      echo' 
<div class="comment-info"> 
<img alt="" class="avatar" height="42" width="42" src="'.$grav_url.'"/> 
<cite> 
<a href="'.$url.'" title="'.$username.'">'.$username.'</a> Says: <br /> 
<span class="comment-data"><a href="'.$url.'" title="'.$date.'">'.$date.'</a></span> 
</cite> 
</div> 
<div class="comment-text"> 
<p>'.BBCode($description).'</p>       
</div> 
     <a href="#post" class="reply" id="'.$id.'">Reply</a> 
        '; 
$query = "SELECT * FROM comments WHERE parent_id ='$id'"; 
$res = mysql_query($query); 
while($row = mysql_fetch_assoc($res)) // Only main comment 
{ $id = $row['id']; 
    $qazi_id = $row['qazi_id']; 
    $username = $row['username']; 
    $email = $row['email']; 
    $description = $row['description'];  
    $url = $row['url']; 
    $parent_id = $row['parent_id']; 
    $date = $row['date']; 
echo' <ul><li> 
<div class="comment-info"> 
<img alt="" class="avatar" height="42" width="42" src="'.$grav_url.'"/> 
<cite> 
<a href="'.$url.'" title="'.$username.'">'.$username.'</a> Says: <br /> 
<span class="comment-data"><a href="'.$url.'" title="'.$date.'">'.$date.'</a></span> 
</cite></div> 
<div class="comment-text"> 
<p>'.BBCode($description).'</p>       
</div> 
</li></ul>'; 
}} 
$i++; 
}echo'</ol></div></div>'; } 
?>

請[不要在新代碼中使用'mysql_ *'函數]（http://stackoverflow.com/questions/12859942/why-shouldnt-i-use-mysql-functions-in-php）。 *他們不再維護，並[已正式棄用]（https://wiki.php.net/rfc/mysql_deprecation）*。看到[紅色框]（http://uk.php.net/manual/en/function.mysql-connect.php）？學習[準備的語句]（http://en.wikipedia.org/wiki/Prepared_statement），並使用[PDO]（http://us1.php.net/pdo）或[MySQLi]（http：// us1.php.net/mysqli）。 [這篇文章]（http://php.net/manual/en/mysqlinfo.api.choosing.php）將幫助你決定哪些。 – 2014-09-23 17:29:17

謝謝，我現在看到了。 – jainul 2014-09-24 00:38:46

PDO在我的服務器中禁用。我之前嘗試啓用它，但失敗了。所以我很快就會在MySQLi上傳輸。謝謝你傑伊布蘭查德。 – jainul 2014-09-24 01:41:05

將您的查詢改爲SELECT * FROM comments WHERE parent_id = 0 ORDER BY id DESC。

謝謝，我會盡快嘗試。 – jainul 2014-09-24 00:36:50

Jason Swett，謝謝你，現在正在工作。但是，如果我有6條評論總共倒過來6次也。這意味着全部通過總評論數反轉。如何解決它？ – jainul 2014-09-24 01:30:35

我明白了，反過來就是停止。使用休息; $ i ++之前;謝謝大家。 – jainul 2014-09-24 02:05:05
