How to confirm payment in paypal using IPN

[vjayis]

Hi

i m a working with paypal to integrate it with my website.,

users can book the hall regarding time basis.

so i m sending the amount to paypal by paynow button created through my paypal test account.

and i inserted the ipn coding in the notify_url specified.

here is the code

<?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 ('www.sandbox.paypal.com', 80, $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'];
$payment_date = $_POST['payment_date'];
$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];
$payment_type = $_POST['payment_type'];
$payment_status = $_POST['payment_status'];
$payment_gross = $_POST['payment_gross'];
$payment_fee = $_POST['payment_fee'];
$settle_amount = $_POST['settle_amount'];
$memo = $_POST['memo'];
$payer_email = $_POST['payer_email'];
$receiver_email = $_POST['receiver_email'];
$txn_id = $_POST['txn_id'];
$txn_type = $_POST['txn_type'];
$payer_status = $_POST['payer_status'];
$address_street = $_POST['address_street'];
$address_city = $_POST['address_city'];
$address_state = $_POST['address_state'];
$address_zip = $_POST['address_zip'];
$address_country = $_POST['address_country'];
$address_status = $_POST['address_status'];
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$tax = $_POST['tax'];
$option_name1 = $_POST['option_name1'];
$option_selection1 = $_POST['option_selection1'];
$option_name2 = $_POST['option_name2'];
$option_selection2 = $_POST['option_selection2'];
$for_auction = $_POST['for_auction'];
$invoice = $_POST['invoice'];
$subscr_id = $_POST['subscr_id'];
if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);

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 and payment_currency are correct
// process payment
// Send a custom email to the value of payer_email
// Set variables needed for email.

//manually checked by writing the output into a text file
$fp1 = fopen('data1.txt', 'w');
fwrite($fp1, $payment_status.$receiver_email);
fwrite($fp1, $req);
fclose($fp1);

$from = "Example name";
$subject = "Thanks for your purchase";
$msg = "Thank you for your purchase. You have successfully finished your payment. ...";
mail($payer_email, $subject, $msg, "From: $from");
}
else if (strcmp ($res, "INVALID") == 0) {
// log for manual investigation
}
}
fclose ($fp);
}
?>

all works fine.

payment gets paid and data's are transferred to the notify_url.

I checked it by writing all the output data's into a text file.

but when the payment is complete the payment_status is "Pending" when it returns to the notify_url.

it gets changed to "Confirmed" only when i log in to my paypal test account and accept the payment.

why that it so happen..

i need to update my database when payment is completed and issue the user a receipt that he had done the booking successfully.

Can i proceed when payment_status is "Pending".

or what should i do.

thanks

regards
vijay

Oops., found the answer.,

Payment Review is enabled in my sandbox account.

Solution:
Turn off this feature in your sandbox account by logging in at https://developer.paypal.com >> click on test accounts >> then, next to your sandbox account, click on 'enabled' under Payment review to disable it.

found it in paypal developer central.
