Paypal Accept Credit Card - php

Well I have a website for which I have a Paypal business account (registered in UK). The paypal is integrated with my website and is working just fine. When user clicks on the "Proceed To Pay" the user is taken to Paypal's website (screenshot below). Now the only problem I have with this procedure is the fact that customers HAVE to make a Paypal account first in order to pay me. I am baffled with all the options Paypal is offering (standard, pro, merchant, what not) and I am not sure what is it exactly that I am doing wrong.

Please advice and explain if I need to change something in my code to let the customer pay using their Credit Card directly(on Paypal's website) rather than asking them to open Paypal account first.
EDIT
The HTML form that is on my confirmorder page is as follow.
<form class="paypal" action="payments.php" method="post" id="paypal_form" target="_parent">
<input type="hidden" name="cmd" value="_xclick" />
<input type="hidden" name="no_note" value="1" />

Fail to send variables back to return address while Paypal payment

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'].

Payment with PayPal hangs inside the notify_url page

I have this page to pay with paypal, and receive the notification in "notify_url". The purchase goes well but fails to receive the notification. Everything is fine until it reaches these two lines: $valid_txnid = check_txnid ($data ['txn_id']);$valid_price = check_price ($data ['payment_amount'], $data ['item_number']);
where the program hangs. (I know it because I have sent emails from various points of the program until I get there that I do not receive anything).
And also I don't know where the check_txnid () and check_price () functions come from, which I don't see defined anywhere. The code is taken from this other post: How to get transaction details in notify_url page in paypal

I don't know where the check_txnid () and check_price () functions come from, which I don't see defined anywhere.
That seems to be your problem. Don't call functions that don't exist.
If you want to to check the transaction ID and the price are unique and valid for what you are offering, create actual functions that actually do this.
You could for example use 'custom' or 'invoice' to match against an existing order record in your database and validate the price corresponds, if you provided such a unique number to PayPal as part of the transaction.

Auto recurring payment for subscriptions plan in codeigniter

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">

<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">
<!-- Set recurring payments until canceled. -->

alt="Subscribe">
<img alt="" width="1" height="1"
src="https://www.paypalobjects.com/en_US/i/scr/pixel.gif" >
</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(){

Issue getting result back from Paypal IPN

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">

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.

In my notify_url page I am getting values as
session_start();
require("ipn_cls1.php");
$paypal_info = $_POST;
print_r($paypal_info);
$paypal_ipn = new paypal_ipn($paypal_info);
$payment_status = trim($paypal_info['payment_status']); // Si Completed : tout est OK echo
$payment_amount = trim($paypal_info['mc_gross']);
i have same problem with paypal adaptive payments in my current project. i have given my
notify_url as http://mysite.com/payment-success. In this page, i simply coded
$request = $_POST;
mail('myid#myaccount', $request);
and then i sent the transaction result to my mail to view.
Note, here in my mail i can able to see the transaction results and if i insert into database, it is inserting but i cant see the transaction results in my page. Try sending to your mail the transaction results.
Create paypal_ipn.php file and place php code in it.
// Response from Paypal
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$value = preg_replace('/(.*[^%^0^D])(%0A)(.*)/i','${1}%0D%0A${3}',$value);// IPN fix
$req .= "&$key=$value";
}
// assign posted variables to local variables
$data['item_name'] = $_POST['item_name'];
$data['item_number'] = $_POST['item_number'];
$data['payment_status'] = $_POST['payment_status'];
$data['payment_amount'] = $_POST['mc_gross'];
$data['payment_currency'] = $_POST['mc_currency'];

There is a really good guide to Instant Payment Notifications (IPN) and understanding how they work. This guide provides you the steps you need to have your notify_url working properly.
There are good code samples provided by Paypal that do the validation response for you, which is really nice. You can use these are the starting point for your own.
