How to Integrate Paypal Payment System in PHP & MySQL
I received a tutorial requests from my reader that asked to me how to implement payment gateway system with Paypal API. In this tutorial I want to explain how to work with Paypal Sandbox test accounts for payment system development and sending arguments while click buy now button. It’s simple and very easy to integrate in your web projects.
Step 1
Create a Paypal Sandbox account at https://developer.paypal.com/
Step 2
Now create test accounts for payment system. Take a look at Sandbox menu left-side top Sandbox->Test Accounts
Step 3
Here I have created two accounts Buyer (personal) and Seller (merchant/business)
index.php
Contains PHP code. Displaying products, product image, product name and product price. Here you have to give your business(seller) $paypal_id id. Modify paypal button form return and cancel_return URLs.
<?php
$paypal_url='https://www.sandbox.paypal.com/cgi-bin/webscr'; // Test Paypal API URL
$paypal_id='your_seller_id'; // Business email ID
?>
<h4>Welcome, Guest</h4>

</div>
<div class="name">
PHPGang Payment
</div>
<div class="price">
Price:$10
</div>
<div class="btn">
<form action="<?php echo $paypal_url; ?>" method="post" name="frmPayPal1">
<input type="hidden" name="business" value="<?php echo $paypal_id; ?>">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="item_name" value="PHPGang Payment">

<img alt="" border="0" src="https://www.sandbox.paypal.com/en_US/i/scr/pixel.gif" width="1" height="1">
</form>
</div>
</div>success.php
Paypal payment success return file. Getting Paypal argument like item_number. Paypal data success.php?tx=83437E384950D&st=Completed&amt=10.00&cc=USD&cm=&item_number=1
<?php
$item_no = $_REQUEST['item_number'];
$item_transaction = $_REQUEST['tx']; // Paypal transaction ID
$item_price = $_REQUEST['amt']; // Paypal received amount
$item_currency = $_REQUEST['cc']; // Paypal received currency type
$price = '10.00';
$currency='USD';
//Rechecking the product price and currency details
if($item_price==$price && $item_currency==$currency)
{
echo "<h1>Welcome, Guest</h1>";
echo "<h1>Payment Successful</h1>";
}
else
{
echo "<h1>Payment Failed</h1>";
}cancel.php
Paypal API cancel_return file.
<?php echo "<h1>Welcome, Guest</h1>"; echo "<h1>Payment Canceled</h1>"; ?>
Step 4
When your web application test payment system workflow is completed. Change the form action development API URLs to original API URLs and give valid $paypal_id seller email id.
$paypal_url='https://www.sandbox.paypal.com/cgi-bin/webscr'; //to $paypal_url='https://www.paypal.com/cgi-bin/webscr';

Very good tutorial so far but I have a small issue with it. I always get the Payment failed in the success page. This is because $item_price and $item_currency are empty. They are empty because the page doesn’t get redirected from the paypal page in 10 seconds like the demo , you have to click return to store and this brings you back to success.php with out anything for $_REQUEST to retrieve instead of success.php?tx=83437E384950D&st=Completed&amt=10.00&cc=USD&cm=&item_number=1. Hope you can help Thanks
Hello Gethin
Auto Return is turned off by default.
To turn on Auto Return:
Log in to your PayPal account at https://www.paypal.com. The My Account Overview page appears.
Click the Profile sub-tab.
The Profile Summary page appears.
Under the Setting Preferences column, click the Website Payment Preferences link. The Website Payment Preferences page appears
Under Auto Return for Website Payments, click the On radio button to enable Auto Return.
In the Return URL field, enter the URL to which you want your payers redirected after they complete their payments.
NOTE: PayPal checks the Return URL that you enter. If the URL is not properly formatted or cannot be validated, PayPal will not activate Auto Return.
Scroll to the bottom of the page, and click the Save button.
step-1 :Please sign in with your sandbox business account on
sandbox.paypal.com
step-2 : than go to profile my selling tool link
step-3: refer image-1
step-4 : refer image-2
sry to say but the pay pal does not return me auttomatically after payment all the settings are done….any other suggestion
The Problem with this is, you have to enter a static url. I wonder how it is possible, to make the redirect go automatically to the page, one has entered in the form from begin with, that url, that you get redirected to, when click on the various “back to page” usw buttons. I would like to have this automatically, so users content can be activated after payment. Or does anyone here know another maybe better way to achieve this?
Thx
Hi i followed this tutorial and your little extra bit about auto-return but the paypal still doesn’t either auto-return or pass along those variables and so keeps displaying the error message about the transcation not being completed. However when i check the actual test accounts in paypal the money has been transferred properly.

i have done this yet it still refuses to auto-return or to pass back the variables for the request[] to grab. Would you have any further suggestions?
tutorial is super simple.
i have a question, Do we need to have a merchant paypal account for accepting payments? and activating Return URL? or it can be done in personal account too?
Yes you can do this on your personal account. Return url is necessary if you want your customers return on your website back after payment. Its upto your application’s requirement.
I logged into my paypal personal account but the problem is When i go to Profile page i do not see these options
Setting Preferences column
Under the Setting Preferences column, click the Website Payment Preferences link
that is why i asked my problem 🙁

Hi i have integrated the paypal it is working fine with the sandbox account but with the live account the transaction id is not generated sir please guide me what may be the error
jeet
how to generate response code for error if transaction failed due to some reason .
Thanks
To All Who Are Not Getting The Data At Return URL or Any Type of Notices So PHPGang Needs To Update There Code To This Updated Code..it Works 100% You Just Need To Add This Field To Your Form As :
And Then Update Your Code In success.php As :
<?php
$item_no = $_POST['item_number'];
$item_transaction = $_POST['txn_id']; // Paypal transaction ID
$item_price = $_POST['payment_gross']; // Paypal received amount
$item_currency = $_POST['mc_currency']; // Paypal received currency type
$price = '10.00';
$currency='USD';
//Rechecking the product price and currency details
if($item_price==$price && $item_currency==$currency)
{
echo "Item No : $item_no”;
echo “Item Transaction ID : $item_transaction”;
echo “Item Price : $$item_price”;
echo “Item Currency : $item_currency”;
echo “Welcome, Guest”;
echo “Payment Successful”;
}
else
{
echo “Payment Failed”;
}
?>

I am getting Payment Failed. But it is a successful transaction.
And how can I replace “[email protected]”, this with my site name and image ?
Add following to your form fields and variables will be returned as $POST fields:
This will work with both auto return on or auto return off.
Hope this will help all those complaining variables were not returning.
quick and effective solutions 🙂
No POST back data will be sent on submit.php. PayPal returns data back to your site via what they call IPN. Its really just a callback to a URL you specify. You can set this URL via the variable notify_url you can send to PayPal. adding rm = 2 not a recommeded method.

dont, just make a function that counts the discount and lets him pay less
Are you kidding? You’re not even checking the autenticity of the transaction id, anyone could fake any transaction!
At least you should say that it is missing, otherwise people will implement this and (surprise surprise) get hacked!

Form field values can be modified on client side, thus resulting in possible transactions of 0.01 in total.
Thanks for clear demo.
