Does paypal send IPN data to localhost when accessing via internet using ngrok? I tested it with Payza and it successfully sent the IPN data and I could insert the data into the database. But when tried with paypal, I am not receiving any data. Does paypal not send to localhost's accessed via internet using ngrok? Or, is there another problem in my code?
I am successfully getting redirected to success page after payment but the data is not inserted in my database.

Please help me guys. I am stuck on this since a few days. I really need to implement it and get through. Please help!!

I am unable to get variables in my return address while paying with Paypal.
My form is like below:
<form action="<?php echo $ps_paypal_url; ?>" method="post">
<input type="hidden" name="business" value="<?php echo $ps_paypal_merchant; ?>">
<input type="hidden" name="notify_url" value="<?php echo 'http://'.$_SERVER['SERVER_NAME'].CONF_WEBROOT_URL. 'paypal-ipn.php'; ?>">
<input type="hidden" name="item_name" value="<?php echo 'For Order ' . $_POST['ORDER']; ?>">
<input type="hidden" name="user_name" value="<?php echo $_SESSION['logged_user']['user_id']; ?>">
<input type="hidden" name="quantity" value="1">
<input type="hidden" name="item_number" value="<?php echo $_POST['ORDER']; ?>">
<input TYPE="hidden" name="cmd" value="_xclick">
<input type="hidden" name="amount" value="<?php echo round($total_payable, 2); ?>">
<?php if($_POST['wallet'] > 0){ ?>
<input type="hidden" name="discount_amount" value="<?php echo round($_POST['wallet'],2); ?>" />
<?php } ?>
<input type="hidden" name="no_shipping" value="1">
<input type="hidden" name="custom" value="<?php echo $_SESSION['logged_user']['user_id']; ?>">
<?php
$success = 'http://' . $_SERVER['SERVER_NAME'] . CONF_WEBROOT_URL .'success/;
?>
<input type='hidden' name='rm' value='2'>
<input type="hidden" name="return" value="<?php echo $success ; ?>">
<input type="hidden" name="currency_code" value="<?php echo CONF_CURRENCY_CODE; ?>">
</form>
In my return address I am trying to read for example item_name or amount. But no success so far. I beleive paypal is disabled this function and variables are not allowed to be posted to return address. In my return file I am trying to read the variables like below:
<?php
$amount = $_GET['amount'];
$amountpost = $_POST['amount'];
echo $amount;
echo $amountpost ;
?>
The result is empty. There is not any problem with ipn file once it is verified I am able to get the result with ipn file but why it is needed for me is because I need to add pending orderd in users purchase history. So when user will be redirected to success.php I will add pending order to account and once it is completed I will check via ipn and will change the status to "paid".
Any help would be highly appreciated.
PS: I don't want to send parameters in URL as $_GET parameters. I just want to get parameters of form.
First, please enable IPN explicitly after logging in your Paypal account and set the IPN url (e.g. set as http://www.yoursite.com/payment1234A.php)
Second, please remove notify_url from your form (to avoid hacking)
Thirdly, please add return and cancel_return url as hidden fields. For example:
<input type="hidden" name="return" value="http://www.yoursite.com/success.php">
<input type="hidden" name="cancel_return" value="http://www.yoursite.com/cancelled.php">
So, if you want to collect USD1000 , then the form to be sent to paypal should be like the following form:
Note:
I have added a javascript autosubmit so that the user does not need to click a submit button);
I have used the "custom" field to send a unique data, it can be something like [customerserial-transactionserial] so that your IPN script can use it to do your db update.
The minimum requested fields to be submitted in the form are:
business, item_name, amount, currency_code. For further details please refer to Paypal's official documentation.
<form id=form1 action="https://www.paypal.com/cgi-bin/webscr" method="post">
<!-- Identify your business so that you can collect the payments. -->
<input type="hidden" name="business" value="yourpaypalemail#yoursite.com">
<!-- Specify a Buy Now button. -->
<input type="hidden" name="cmd" value="_xclick">
<!-- Specify details about the item that buyers will purchase. -->
<input type="hidden" name="item_name" value="Purchase">
<input type="hidden" name="amount" value="1000">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="custom" value="<?php echo $_SESSION["checkcode"]; ?>">
<input type="hidden" name="return" value="http://www.yoursite.com/success.php">
<input type="hidden" name="cancel_return" value="http://www.yoursite.com/cancelled.php">
</form>
<script>
document.getElementById('form1').submit();
</script>
Finally, use (and customize if necessary) the following standard paypal IPN php script in your IPN link (e.g.payment1234A.php). Please note that the amount you submitted will be returned as $_POST['mc_gross'] (not $_GET['amount'] nor $_POST['amount']) . But the custom field will be returned as $_POST['custom'].
The file below : payment1234A.php

Here, I'm want to using auto recurring payment in paypal for my subscription plan. I have found some solutions but not working in IPN recurring payment.
First time payment is working but not getting recurring payment auto deduction.
i'm using html code for payment in paypal gateway.
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<!-- Identify your business so that you can collect the payments. -->
<input type="hidden" name="business" value="alice#mystore.com">

<!-- Identify the subscription. -->
<input type="hidden" name="item_name" value="Alice's Weekly Digest">
<input type="hidden" name="item_number" value="DIG Weekly">
<!-- Set the terms of the regular subscription. -->
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="a3" value="5.00">
<input type="hidden" name="p3" value="1">
<input type="hidden" name="t3" value="M">

</form>
For auto recurring payment you have to use ipn also. Add below code in your HTML form before submit button.
<input type="hidden" name="custom" value="User_id">
<!-- specify urls -->
<!-- paypal_cancel_url -->
<input type="hidden" name="cancel_return" value="http://localhost/xxxxx/paypal/cancel">
<!-- paypal success return url -->
<input type="hidden" name="return" value="http://localhost/xxxxx/paypal/success">
<!-- paypal ipn return url for auto recurring payment -->
<input type="hidden" name="notify_url" value="http://localhost/xxxxx/paypal/ipn">
I'm only showing recurring payment guide as you said first time payment is working. Add below code in PayPal controller.
function ipn(){
if ($_SERVER['REQUEST_METHOD'] != "POST") die ("No Post Variables");
$req = 'cmd=_notify-validate';
// Read the post from PayPal
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}

$paypalURL = 'https://www.sandbox.paypal.com/cgi-bin/webscr';

$req = str_replace("&", "\n", $req); // Make it a nice list in case we want to email it to ourselves for reporting

My question is, how can I get the two inputs (id: afield) so that I can save them for when the user returns to my website after paying, I can use them. I am using PHP.
Thanks
Here is how I have dealt with this in the past.
First step is to fix the input field:
<input id="afield" type="text" placeholder="Name" name="afield">
I have corrected your HTML syntax and called the field afield
You then need to set another hidden field called notify_url - this is the URL that PayPal will POST the transaction details back to after a payment has been made.
e.g.
<input type="hidden" name="notify_url" value="https://www.yourdomain.com/paypal.php">
Inside paypal.php you can then access $_POST['afield']
In case it helps, here is the sort of thing you need inside paypal.php - this verifies that the transaction details POSTed back from PayPal are genuine and that the payment was successful:
$raw_post_data = file_get_contents('php://input');
$raw_post_array = explode('&', $raw_post_data);
$myPost = array();
foreach ($raw_post_array as $keyval) {
$keyval = explode ('=', $keyval);
if (count($keyval) == 2)
$myPost[$keyval[0]] = urldecode($keyval[1]);
}
// read the IPN message sent from PayPal and prepend 'cmd=_notify-validate'
$req = 'cmd=_notify-validate';
if (function_exists('get_magic_quotes_gpc')) {
$get_magic_quotes_exists = true;
}
foreach ($myPost as $key => $value) {
if ($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) {
$value = urlencode(stripslashes($value));
} else {
$value = urlencode($value);
}
$req .= "&$key=$value";
}
// Step 2: POST IPN data back to PayPal to validate
$ch = curl_init('https://ipnpb.paypal.com/cgi-bin/webscr');
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_FORBID_REUSE, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close'));
if ( !($res = curl_exec($ch)) ) {
curl_close($ch);
exit;
}
curl_close($ch);
if (strcmp ($res, "VERIFIED") == 0 and $_POST['payment_status'] == 'Completed') {
// payment has been verified
}
You can add a field with the name custom
The only issue is this field can't be returned by Paypal in the answer, even in the PDT
Only can see this field in the IPN text

I am trying to make a donation in my website with paypal. As the result, I want the donators to be displayed. For that I use ipn. I figured and made it working, but it seems to be working fine only with paypal sandbox only.

I have followed the pay pal IPN documentation on this. Created a file called payment_notify.php its identical to whats found here : https://developer.paypal.com/docs/classic/ipn/ht_ipn/
My pay pal form is set to POST data to : https://www.sandbox.paypal.com/cgi-bin/webscr
I have my pay pal sandbox business account notify url set to my website url / payment_notify.php.
My code allows users to click the buy now button, it brings them to the paypal login screen, allows them to 'pay' for the product, displays a paypal screen saying the transaction was successful then finally when it returns to my site it gives me back nothing. I have tried inserting the POST variables from paypal into my database but nothing happens.
Im a total beginner at paypal API but heres my attempt :
<form action="<?php echo $paypal_url; ?>" method="post">
<!-- Identify your business so that you can collect the payments. -->
<input type="hidden" name="business" value="<?php echo $paypal_id; ?>">
<!-- Specify details about the item that buyers will purchase. -->
<input type="hidden" name="item_number" value="<?php echo $row['id'];?>">
<input type="hidden" name="item_name" value="<?php echo $row['credit_price'].": credits"; ?>">
<input type="hidden" name="amount" value="<?php echo $row['credit_price']; ?>">
<input type="hidden" name="currency_code" value="<?echo $row['currency'];?>">
<!-- Specify URLs -->
<input type='hidden' name='cancel_return' value="<? echo 'http://www.$_SERVER[HTTP_HOST]/cancel.php';?>">
<input type='hidden' name='return' value="<? echo 'http://www.$_SERVER[HTTP_HOST]/success.php';?>">
<input type='hidden' name='notify_url' value="<? echo 'http://www.$_SERVER[HTTP_HOST]/payment_notify.php';?>">
<!-- Specify a Buy Now button. -->
<input type="hidden" name="cmd" value="_xclick">
<input type="image" name="submit" border="0"
src="https://www.paypalobjects.com/en_US/i/btn/btn_buynowCC_LG.gif" alt="PayPal - The safer, easier way to pay online">
<img alt="" border="0" width="1" height="1" src="https://www.paypalobjects.com/en_US/i/scr/pixel.gif" >
</form>
Then for my payment_notify file :
<?php
session_start();
require("db_connection.php");
// STEP 1: read POST data
// Reading POSTed data directly from $_POST causes serialization issues with array data in the POST.
// Instead, read raw POST data from the input stream.
$raw_post_data = file_get_contents('php://input');
$raw_post_array = explode('&', $raw_post_data);
$myPost = array();
foreach ($raw_post_array as $keyval) {
$keyval = explode ('=', $keyval);
if (count($keyval) == 2)
$myPost[$keyval[0]] = urldecode($keyval[1]);
}
// read the IPN message sent from PayPal and prepend 'cmd=_notify-validate'
$req = 'cmd=_notify-validate';
if (function_exists('get_magic_quotes_gpc')) {
$get_magic_quotes_exists = true;
}
foreach ($myPost as $key => $value) {
if ($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) {
$value = urlencode(stripslashes($value));
} else {
$value = urlencode($value);
}
$req .= "&$key=$value";
}
// Step 2: POST IPN data back to PayPal to validate
$ch = curl_init('https://www.paypal.com/cgi-bin/webscr');
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_FORBID_REUSE, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close'));
if ( !($res = curl_exec($ch)) ) {
// error_log("Got " . curl_error($ch) . " when processing IPN data");
curl_close($ch);
exit;
}
curl_close($ch);
// inspect IPN validation result and act accordingly
if (strcmp ($res, "VERIFIED") == 0) {
// The IPN is verified, process it:
$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 = $_POST['payer_email'];
foreach($_POST as $key => $value) {
echo $key . " = " . $value . "<br>";
}
// insert the valid transaction into the database :
$insert = "INSERT INTO tableNAME (item,txn_id,payment_gross,currency_code,paid_by,payment_status)VALUES('$item_number',$txn_id,'$payment_amount','$payment_currency','$payer_email','$payment_status')";
$result=mysqli_query($con,$insert);
} else if (strcmp ($res, "INVALID") == 0) {
// IPN invalid, log for manual investigation
echo "The response from IPN was: <b>" .$res ."</b>";
}
?>
You have to check two things here:
Change $ch = curl_init('https://www.paypal.com/cgi-bin/webscr'); to
$ch = curl_init('https://www.sandbox.paypal.com/cgi-bin/webscr');
Try to get the result of response in log file to see what is the actual result you are getting.
