我正在嘗試創建一個將從我的數據庫表中編輯行的窗體。 (基於我從一個StackOverflow頁面獲得的一些代碼。)無法使用表格編輯mysql行
我能夠使用相關數據填充表單,但是當我提交表單時,行未更新。實際上,我的一些列已被刪除。
我做錯了什麼?
edit.php
<?php
$UID = (int)$_GET['f'];
$query = mysql_query("SELECT * FROM user_feeds WHERE feed_id = '$UID'") or die(mysql_error());
if(mysql_num_rows($query)>=1){
while($row = mysql_fetch_array($query)) {
$feedtitle = $row['feed_title'];
$feedurl = $row['feed_url'];
$feedorder = $row['feed_order'];
$feedowner = $row['feed_owner'];
}
?>
<form action="update.php" method="post">
<input type="hidden" name="ID" value="<?=$UID;?>">
Title:<br /> <input type="text" name="ud_feedtitle" value="<?=$feedtitle?>"><br>
URL: <br /> <input type="text" name="ud_feedurl" value="<?=$feedurl?>"><br>

}else{
echo 'No entry found. <a href="javascript:history.back()">Go back</a>';
}
?>
</div>
</body>
</html>
update.php
<?php
$ud_ID = $_REQUEST["ID"];
$ud_feedtitle = $_POST["feed_title"];
$ud_feedurl = $_POST["feed_url"];
$ud_feedorder = $_POST["feed_order"];
$ud_feedowner = $_POST["feed_owner"];
$query = "UPDATE user_feeds SET feed_title = '$ud_feedtitle', feed_url = '$ud_feedurl', feed_order = '$ud_feedorder', feed_owner = '$ud_feedowner', WHERE feed_id = '$ud_ID'";
$res = mysql_query($query);
if ($res)
echo "<p>Record Updated<p>";
else
echo "Problem updating record. MySQL Error: " . mysql_error();
?>
我不明白你爲什麼用'while'語句來覆蓋'$ feed ...'變量。 – 2012-07-29 14:56:41
