我正在構建一個非常基礎的論壇,可以對帖子發表評論。正如您所看到的,此代碼顯示了評論以及評論作者何時與登錄用戶相同時,它應該顯示刪除按鈕以刪除評論。現在的問題是,當我點擊刪除按鈕時,它會刪除帖子上的所有評論,而不僅僅是評論旁邊的刪除按鈕。MYSQL刪除特定行按鈕PHP
我的「意見」表有列ID,盤標識符,comment_username,評論和COMMENT_TIME,其中從「意見」盤標識符列指的是ID列在表「dicussions」
<?php
$id = mysql_real_escape_string($_GET['id']);
$query = 'SELECT * FROM discussions WHERE `id` = '.$id.' LIMIT 1';
$result = mysql_query($query);
$row = mysql_fetch_array($result);
?>
<h2><? echo $row['category'] . $row['topic']; ?></h2>
<div>Posted on <? echo $row['date_time']; ?> by <? echo $row['username'] ?></div>
<div><? echo $row['discussion']; ?></div>
<?
$result_comments = mysql_query("SELECT * FROM comments WHERE discid = $id ORDER BY comment_time ASC");
while ($record = mysql_fetch_array($result_comments))
{
?>
<form action="" method="POST" >
<? echo $record['comment_username']. $record['comment_time'] ?>
<!-- if comment from logged in user, show delete option -->
<?
if ($record['comment_username'] == $log_username)
{
echo '<span><button title="Delete comment" value="' . $record['id'] .'" name="deletecommentbutton" type="submit">X</button></span>';
}
if(isset($_POST['deletecommentbutton']))
{
$commentid = $record['id'];
$result_delete = mysql_query("DELETE from comments WHERE id='$commentid'");
header("Location: url/discussion_view.php?id=".$_GET['id']."");
}
?>
<div><? echo $record['comment'] ?></div></form>
<?php } ?>
如何僅爲選定的ID執行? –
只需使用'$ _POST ['deletecommentbutton']'這是所選評論的ID。但不要忘記消毒! –
你可以給我一個例子或一種方式來開始?我無法工作:( –
