从list     传一个id值到edit页面编辑保存。

<body>
<?php
require('../lib/common.php');
error_reporting(0);
$sql = "select * from notebook where id=".$_GET['id'];
$result = mysql_query($sql);
$row = mysql_fetch_array($result);
?>
<form id="form1" name="edit" method="post" action="edit.php?action=save">
<table width="600" border="1">
<tr>
    <td width="192" align="right">标题：</td>
    <td width="392"><input name="title" type="text" size="50" value="<?php echo $row['title'] ?>" /></td>
</tr>
<tr>
    <td align="right">内容：</td>
    <td><textarea name="content" cols="60" rows="10"><?php echo $row['content'] ?></textarea>
    <input type="hidden" name="id" value="<?php echo $row['id'] ?>"
    </td>
</tr>
<tr>
    <td align="right"> </td>
    <td><input type="submit" name="Submit" value="提交" /> <a href="javascript:history.go(-1);">返回</a></td>
</tr>
</table>
</form>
<?php
if($_GET['action']=='save'){
    $title = trim($_POST['title']);
    $content = trim($_POST['content']);
    $content = str_replace("\n","<br>",str_replace(" "," ",$content));
    $date = date('Y-m-d H:i:s');
    $sql = "update notebook set title='$title',content='$content',date='$date' where id=".$_POST['id']; // 这里直接$_GET['id']为什么更新失败？ $_GET['id']的值在此取不到吗？
    mysql_query($sql);
    echo "修改成功! <a href='list.php'>查看列表</a>";}
    ?>
</body>
