我有一個動態頁面（holidays.php），在URL holidays.php使用get方法是這樣的ID來的數據？ID = 1如何與形式發送ID在PHP
代碼
include('header.php');
include('db.php');
$id = $_GET['id'];
$sql_hp = "select * from `holiday_package` where `id` ='$id'";
$res_hp = mysql_query($sql_hp);
$rec_hp = mysql_fetch_array($res_hp);
和我有一個聯繫表格在同一頁面，客戶端填寫併發送電子郵件給管理員。
<form action="holidays-form.php" method="post">
<!--<span class="success"><?php echo $smsg; ?></span>
<span class="fail"><?php echo $emsg; ?></span>-->

我經過假期-form.php的頁面發送郵件，請參閱下面
<?php
$name = $_POST['name'];
$email = $_POST['email'];
$mobile = $_POST['mobile'];
$date = $_POST['date'];
$pkg_title = $_POST['pkg_title'];
$pkg_price = $_POST['pkg_price'];
$adult = $_POST['adult'];
$from = 'Company Name';
$to = "[email protected]";
$subject = "New Holiday Package Submission";
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers = 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$message = '<html><body>
<table width="500" border="0" cellspacing="0" cellpadding="0" style="border:#ccc solid 1px;">
<tr>
<td width="151" height="30" style="background:#f3f3f3; padding-left:5px;">Name</td>
<td width="149" style="background:#f3f3f3; padding- right:5px;">'.$name.'</td>
</tr>
<tr>
<td height="30" style="padding-left:5px;">Email</td>
<td style="padding-right:5px;">'.$email.'</td>
</tr>
<tr>
<td height="30" style="background:#f3f3f3; padding-left:5px;">Mobile</td>
<td style="background:#f3f3f3; padding-right:5px;">'.$mobile.'</td>
</tr>
<tr>
<td height="30" style="padding-left:5px;">Date</td>
<td style="padding-right:5px;">'.$date.'</td>
</tr>
<tr>
<td height="30" style="background:#f3f3f3; padding-left:5px;">Package Name</td>
<td style="background:#f3f3f3; padding-right:5px;">'.$pkg_title.'</td>
</tr>
<tr>
<td height="30" style="padding-left:5px;">Package Price (adult) </td>
<td style="padding-right:5px;">'.$pkg_price.'</td>
</tr>
<tr>
<td height="30" style="background:#f3f3f3; padding-left:5px;">Package Price (child)</td>
<td style="background:#f3f3f3; padding-right:5px;">'.$adult.'</td>
</tr>
</table>
</body></html>';
$success = mail($to,$subject,$message,$headers);
if ($success == true) {
header("Location:holidays.php?s=mail sent");
}
else {
header("Location:holidays.php?s=error");
}
?>
我想表明在holidays.php成功消息的代碼，我已經寫了像表單標籤代碼此
<?php
$s = $_GET['s'];
if ($s=="mail sent") {
echo ('<span class="success">Thankyou! Your Package Has been Successfully Submitted!. We will Feedback you asap.</span>');
}
else if ($s=="error") {
echo ('<span class="fail">Sorry! Please ensure you have filled all fields Correctly.</span>');
}
但是提交示出這樣的錯誤形式holidays.php頁後（注：未定義指數：ID在C：\ XAMPP \ htdocs中\棘手-旅行者\第4行holidays.php）成功messag即所以我如何存儲或發送我在頁面頂部使用的$ id值。
