所以，我正在做一个销售会员计划的网站。用户点击计划，系统将显示注册表。在表单中，我需要获取用户的IC编号（这是我正在工作的国家/地区的合法身份证号码）和用户创建的密码。然后，用户单击“订阅”按钮。用户将被引导至paypal处理页面。
form method='post' action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_ext-enter">
<input type="hidden" name="redirect_cmd" value="_xclick-subscriptions">
<input type="hidden" name="item_number" value="<?php echo $plan[0]['id'];?>">
<input type="hidden" name="no_note" value="1">
<input type="hidden" name="item_name" value="<?php echo $plan[0]['plan_name'];?>">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="a3" value="<?php echo $plan[0]['plan_price'];?>">
<input type="hidden" name="p3" value="1">
<input type="hidden" name="t3" value="D">
<input type="hidden" name="src" value="1">
<input type="hidden" name="sra" value="1">
<input type="hidden" name="business" value="seller@test.com">
<input type="hidden" name="return" value="<?php echo base_url(); ?>">
<input type="hidden" name="notify_url" value="<?php echo base_url(); ?>payment/subscribe" />
<input type="hidden" name="rm" value="2">
<label for='icno'>IC No</label><input type='text' name='icno'/>
<label for='password'>Password</label><input type='password' name='password'/>
<input type='image' src="<?php echo base_url(); ?>assets/images/sign_up_btn.png" alt="" border="0" />
</form>
如果重要的话，我正在使用codeigniter框架。在我的主页返回页面上，我编写了这个代码：
<?php
$posted_data = print_r($_POST,true);
file_put_contents('posted_data.txt',$posted_data);
?>
而我的控制器是notify_url（付款/订阅）：
public function subscribe() {
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://sandbox.www.paypal.com', 443, $errno, $errstr, 30);
$payer_email = $_POST['payer_email'];
$icno = mysql_real_escape_string($_POST["custom"]);
$txn_type = $_POST['txn_type'];
if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
$s = "insert into test(name) values('$icno')";
$result = mysql_query($s);
}
}
else if (strcmp ($res, "INVALID") == 0) {
// log for manual investigation
}
}
fclose ($fp);
}
所以，购买过程顺利。问题是，然后用户点击返回我们网站的按钮，它不会更新数据库（插入测试（名称）值（'$ icno'））。我做错了什么？
顺便说一下，在用户返回主站点后，会创建一个.txt文件，但只存储此信息

如果你问我为什么不尝试IPN;我刚开始学习如何进行paypal集成，因此我最好学会如何做到这两点。
我试图改变：
if (strcmp ($res, "VERIFIED") == 0) {
$s = "insert into test(name) values('$icno')";
$result = mysql_query($s);
}
到
if (strcmp ($res, "txn_type") == "subscr_signup") {
$s = "insert into test(name) values('$user_id')";
$result = mysql_query($s);
}
它仍然不会更新数据库
