我得到未定義的錯誤，我不明白爲什麼的價值...傳遞現場未定義的錯誤
「注意：未定義指數：測試中...」
這裏是pageA的完整的源代碼：
<?php
if(isset($_POST['save'])) {
print "<pre>";
print_r($_POST);
print "</pre>";
}

THIS IS網頁B的全碼
<?php

if (!$con)

}
mysql_select_db("myDB");
$id = (int)$_GET['id']; //ERROR POINTS TO HERE
$sql="UPDATE pages SET content=('$_POST[elm1]') WHERE id='.$id.'";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
echo "1 record added";
$query = "SELECT * FROM pages where id=1";
$result = mysql_query($query);
$row = mysql_fetch_assoc($result);
$contents = $row['content'];
echo $contents;
mysql_close($con)

錯誤是：
通知：未定義指數：ID在C：\瓦帕\ WWW \ pageB.php上線

試過並添加了：$ id = $ _GET ['id'];到pageB，但得到undefined :( – Satch3000 2012-03-16 11:55:50
什麼是完整的錯誤信息，它是與'test'或'id'有關嗎？ – MrCode 2012-03-16 12:03:31
