更新1：真搞不清楚PayPal付款
寫$res到文本文件只是返回字VERIFIED：
<?php
/*
mysql_connect("localhost", "user", "password") or die(mysql_error());
mysql_select_db("PayPal") or die(mysql_error());
*/
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_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://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
$ourFileName = "payment_successful.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fwrite($ourFileHandle, $res);
fclose($ourFileHandle);
}
else if (strcmp ($res, "INVALID") == 0) {
$ourFileName = "payment_failed.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fwrite($ourFileHandle, $res);
fclose($ourFileHandle);
}
}
fclose ($fp);
}
?>
原題：
我有以下的IPN（即時付款通知）腳本，它可以工作，即如果成功則創建成功的文件，如果失敗則創建失敗的文件。
PayPal是否會向IPN文件返回寄存值，以便我能夠確定哪些付款已成功或付款失敗？
如果是，我該如何訪問這些值？
如果不是，我該如何確定哪些付款已被接受或拒絕？
這是IPN文件我目前擁有的腳本：
<?php
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_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://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
$ourFileName = "payment_successful.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);
}
else if (strcmp ($res, "INVALID") == 0) {
$ourFileName = "payment_failed.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);
}
}
fclose ($fp);
}
?>
沒關係，我想通了，什麼是貝寶返回。 – oshirowanen 2011-04-08 08:30:18
