Hi I know that there are many questions already in SO related to my problem but I have not got solution from any of them. I have implemented paypal. It is working well. Now I want to implement ipn in my paypal implementation. I have searched through and found some code. I have implemented that but I am getting invalid ipn. I can get all details from paypal transaction but for ipn it is always invalid. I have used following code in DoExpressCheckoutPayment.php file
$req = 'cmd=_notify-validate';
foreach ($_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";
// If testing on Sandbox use:
$header .= "Host: www.sandbox.paypal.com:443\r\n";
//$header .= "Host: www.paypal.com:443\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
// If testing on Sandbox use:
//$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
$fp =fsockopen('ssl://www.sandbox.paypal.com',443,$err_num,$err_str,30);
echo('<br>'.$req);
// assign posted variables to local variables
/*$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];*/
if (!$fp)
{
echo(' HTTP ERROR');
}
else
{
fputs ($fp, $header . $req);
while (!feof($fp))
{
$res = fgets ($fp, 1024);
echo('<br> res is '.$res);
if (strcmp ($res, "VERIFIED") == 0)
{
// check the payment_status is Completed
// check that txn_id has not been previously processed
// check that receiver_email is your Primary PayPal email
// check that payment_amount/payment_currency are correct
// process payment
$mail_From = "From: [email protected]";
$mail_To = "[email protected]";
$mail_Subject = "VERIFIED IPN";
$mail_Body = $req;
foreach ($_SESSION as $key => $value)
{
$emailtext .= $key . " = " .$value ."\n\n";
}
if(mail($mail_To, $mail_Subject, $emailtext . "\n\n" . $mail_Body, $mail_From))
echo('<br>mail 1 sent');
else
echo('<br>mail1 not sent');
}
else if (strcmp ($res, "INVALID") == 0)
{
// log for manual investigation
$mail_From = "From: [email protected]";
$mail_To = "[email protected]";
$mail_Subject = "INVALID IPN";
$mail_Body = $req;
foreach ($_SESSION as $key => $value)
{
$emailtext .= $key . " = " .$value ."\n\n";
}
if(mail($mail_To, $mail_Subject, $emailtext . "\n\n" . $mail_Body, $mail_From))
echo('<br>mail sent');
else
echo('<br>not sent');
}
}
fclose ($fp);
}
我正在其他文件中设置notify_url,而该文件是指向这样的文件
I am setting notify_url in other file which is directing to this file like this
<input type="hidden" name="notify_url" value="http://www.mysite.com/paypal/DoExpressCheckoutPayment.php"/>
我收到以下电子邮件:
**notify_url = http://www.mysite.com/paypal/DoExpressCheckoutPayment.php
cmd=_notify-validate¬ify_url=http%3A%2F%2Fwww.mysite.com%2Fpaypal%2FDoExpressCheckoutPayment.php**
有一件事,我注意到我没有从$ _POST得到任何东西.我的$ _POST为空.请告诉我我错了.谢谢
One thing that I have notice that I am not getting any thing from $_POST. My $_POST is empty.Please tell me where I am wrong.Thanks
推荐答案
在此处尝试此代码.它与您上面使用的略有不同.它对我有用.
Try this code here. It is slightly different to the one you used above. It works for me.
<?php
$req = 'cmd=_notify-validate';
foreach ($_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);
// assign posted variables to local variables
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];
if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
//Process Order
}else if (strcmp ($res, "INVALID") == 0) {
//Send Email To You
}
}
fclose ($fp);
}
?>
