我已經成功地設置了一個表單，它接受用戶的詳細信息，然後在提交之後，在將細節添加到mySQL數據庫之前進行PayPal付款。Paypal與MySQL的IPN集成
這裏是我的html：
<form id="paypal_form" class="paypal" action="payments.php" method="post" target="_blank">
Membership:
<input type="hidden" name="on0" value="Membership">
<select name="os0">
<option value="Level 1">Level 1 - £21.00 GBP</option>
<option value="Level 2">Level 2 - £25.00 GBP</option>
<option value="Level 3">Level 3 - £65.00 GBP</option>
</select>
<input type="text" name="title" value="" />
<input type="text" name="name" value="" />
<input type="text" name="surname" value="" />
<input type="text" name="address_1" value="" />
<input type="text" name="address_2" value="" />
<input type="text" name="address_3" value="" />
<input type="text" name="county" value="" />

<input name="currency_code" type="hidden" value="GBP" />
<input name="bn" type="hidden" value="PP-BuyNowBF:btn_buynow_LG.gif:NonHostedGuest" />
<input name="payer_email" type="hidden" value="[email protected]" />
<input name="item_number" type="hidden" value="123456" />
<input type="submit" value="Submit Payment" class="button large orange" />
</form>
這裏是我的payments.php文件：

這裏是我的functions.php文件：
<?php

if ($row = mysql_fetch_array($sql)) {

}
return $valid_txnid;
}
function check_price($price, $id)
{
$valid_price = false;
/*
you could use the below to check whether the correct price has been paid for the product

$sql = mysql_query("SELECT amount FROM `products` WHERE id = '$id'");
if (mysql_numrows($sql) != 0) {
while ($row = mysql_fetch_array($sql)) {
$num = (float)$row['amount'];
if($num == $price){
$valid_price = true;
}
}
}
return $valid_price;
*/
return true;
}
function updatePayments($data)
{
global $link;
if (is_array($data)) {
$sql = mysql_query("INSERT INTO `payments` (txnid, payment_amount, payment_status, itemid, createdtime) VALUES (
'" . $data['txn_id'] . "' ,
'" . $data['payment_amount'] . "' ,
'" . $data['payment_status'] . "' ,
'" . $data['item_number'] . "' ,
'" . date("Y-m-d H:i:s") . "'
)", $link);
return mysql_insert_id($link);
}
}
?>
這裏是我的MySQL查詢哪個設置我的數據庫表是正確的：
CREATE TABLE IF NOT EXISTS `payments` (
`id` int(6) NOT NULL AUTO_INCREMENT,
`txnid` varchar(20) NOT NULL,
`payment_amount` decimal(7,2) NOT NULL,
`payment_status` varchar(25) NOT NULL,
`itemid` varchar(25) NOT NULL,
`createdtime` datetime NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
我很高興它的所有工作方式和信息通過成功付款後傳入我的數據庫。然而，我的問題是，我如何將附加的html表單域（例如名稱，姓氏，地址_1）發送到mySQL數據庫？
非常感謝您的幫助。
我認爲我需要編輯functions.php和payments.php文件，但我沒有經驗的MySQL，不知道如何去做，而不會破壞似乎迄今爲止工作的過程。
再次感謝！
