Payment System with Paypal

I received a tutorial requests from my reader that asked to me how to implement payment gateway system with Paypal API. In this post 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.

Payment System

Download Script     Live Demo

Sample database design for Payment system. Contains there table users, products and sales.
Payment process database design

CREATE TABLE `users` (
`username` varchar(255) UNIQUE KEY,
`password` varchar(255),
`email` varchar(255) UNIQUE KEY,

CREATE TABLE `products`
`product` varchar(255),
'product_img` varchar(100),
`price` int(11),
`currency` varchar(10),

`pid` int(11),
`uid` int(11),
`saledate` date,
`transactionid` varchar(125),
FOREIGN KEY(pid) REFERENCES products(pid)

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
Creating Paypal Test Account

Step 3
Here I have created two accounts Buyer (personal) and Seller (merchant/business)
Paypal test accounts

Contains PHP code. Displaying records from products table 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.
require 'db_config.php';
$paypal_url='https://www.sandbox.paypal.com/cgi-bin/webscr'; // Test Paypal API URL
$paypal_id='your_seller_id'; // Business email ID

<h2>Welcome, <?php echo $username;?></h2>
$result = mysql_query("SELECT * from products");
while($row = mysql_fetch_array($result))
<img src="images/<?php echo $row['product_img'];?>" />
Name: <?php echo $row['product'];?>
Price: <?php echo $row['price'];?>$
// Paypal Button 
<form action='<?php echo $paypal_url; ?>' method='post' name='form<?php echo $row['pid']; ?&gt;'>
<input type='hidden' name='business' value='<?php echo $paypal_id; ?>'>
<input type='hidden' name='cmd' value='_xclick'>
<input type='hidden' name='item_name' value='<?php echo $row['product'];?>'>
<input type='hidden' name='item_number' value='<?php echo $row['pid'];?>'>
<input type='hidden' name='amount' value='<?php echo $row['price'];?>'>
<input type='hidden' name='no_shipping' value='1'>
<input type='hidden' name='currency_code' value='USD'>
<input type='hidden' name='cancel_return' value='http://yoursite.com/cancel.php'>
<input type='hidden' name='return' value='http://yoursite.com/success.php'>
<input type="image" src="https://paypal.com/en_US/i/btn/btn_buynowCC_LG.gif" name="submit">


Paypal payment success return file. Getting Paypal argument like item_number. Paypal data success.php?tx=270233304D340491B&st=Completed&amt=22.00&cc=USD&cm=&item_number=1
require 'db_config.php';
$uid = $_SESSION['uid'];
$item_no = $_GET['item_number'];
$item_transaction = $_GET['tx']; // Paypal transaction ID
$item_price = $_GET['amt']; // Paypal received amount
$item_currency = $_GET['cc']; // Paypal received currency type

//Getting product details
$sql=mysql_query("select product,price,currency from producst where pid='$item_no'");

//Rechecking the product price and currency details
if($item_price==$price && item_currency==$currency)

$result = mysql_query("INSERT INTO sales(pid, uid, saledate,transactionid) VALUES('$item_no', '$uid', NOW(),'$item_transaction')");
echo "<h1>Welcome, $username</h1>";
echo "<h1>Payment Successful</h1>";
echo "Payment Failed";

Positive approach

Paypal API cancel_return file.
echo "<h1>Welcome, $username</h1>";
echo "<h1>Payment Canceled</h1>";

Negative approach

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.

How we can get the commission for each sales.. mean if some one sells any products using my website i need to take 5% from the total amount of the product. How it can be done in Paypal. so that 5% amount is automatically transferred to my paypal account.

Jirawatee said...

Well done. Thank you guy.

Sreevathsa said...

Hi srini, nice tute as usual..:) is creating test account on paypal free or payable?

Dan said...

Srinivas, I'm curious about your database graph. What do you use when designing databases?

Hey Great tutorial, Srinivas, thank you from PerĂº.

Omg.... Asians rock!

Great post Srinivas... we like these kind of innovative posts. Thanks a lot.

SQL Injection, no verification that a call to success.php actually came from PayPal (and is valid)...words fail me.

waw..thanks for sharing Srinivas..:)

You have a big logical error in your code. You don't check what your code in success.php called from PayPal. Anyone can create html file (at the his own PC) with code like next:
<--FORM action="yoursite/success.php">
<--input type="text" name="item_number" value="Item1">
<--input type="submit"><--/FORM>.
This code calls to your page success.php and send there "item_number=Item1". And your page thinks what PayPal payment is accepted. But operation performed without PayPal.

mobikwik said...

thanks for sharing, paypal API is actually pretty complicated because there are too many options. We faced these issues while doing the integrations for http://www.mobikwik.com

Ashish said...


i tried your code and it worked fine for me, the only error i got is i am not getting the product id after successful transaction and getting "Payment Error" while inserting record in database...

Anonymous said...

Hey Srini,
i got the same error like ashish...

Nice post. I solved my problem very well.

Modified 'success.php' file code. Re-checking the product price and currency details

Sreevathsa said...

hi srini, my question is .. in step 1 we need to register for the sandbox account.. is it paid account ??

Srinivas Tamada said...


It's free just test account

kuldeep singh sadioura said...

hey Sri its not TEXT ACCOUNT its TEST Brother I think a little typo mistake is there.. :)

Anonymous said...

i am confused - cant anyone just call the success.php page and post sales? Usually I would assume you need to use PayPal IPN or something - its a good example but I am not sure if this is practical?

Al said...

For me its not safe, also the return url dont have transaction id for me.

saideep said...

Very Handy tuts :)

anton said...

item_number. Paypal data success.php?tx=270233304D340491B&st=Completed&amt=22.00&cc=USD&cm=&item_number=1

what $_GET[???], is Quantity???

Pawan Sharma said...

its post is nice but why are you using IPN for update database.

KOKARAT said...

Please advice how to use this tutorail to protect digital file. if success able to download file if not protected digital file.

rkl said...

Hi. Thanks for the tutorial. Everything works fine, except the redirection to the success page after the payment. Paypal doesn't redirect, it only confirms the payment and shows a link: Back to Robert Kleinert's Teststore. When I click on that link Paypal redirects to success.php?merchant_return_link=Back+to+Robert+Kleinert's+Test+Store

Whats the problem here? Or is it only a sandbox problem?


rikoy said...

nice info..

Nguyen Hai dang said...

Dear Srinivas Tamada,

i have downloaded import database o.k, tested o.k all, only url of success it still success.php not added more params. did you shared not enought code ? please check. i'm trying with ipn and use curt of php to test with more code.

Anonymous said...

Same with Nguyen Hai Dang

Srinivas Tamada said...

Sanbox new accounts success redirection problem.

Igor Azevedo said...

It was helpfull for me, however I think it is insecure to rely just on the data sent to the success.php file to verify the sale.

I added a field named 'verified' to the Sales table which defaults to '0'.
I then created a ipn.php file that is called by Paypal once the payment is received. This file then searches for the correct transactionid already on the table and changes the value of 'verified' to '1'.

This way you know the payment is legit because it's confirmed by Paypal itself. Otherwise people can just call the success.php directly and insert fake payments.

I think that having this is enough to make the process secure. Do you guys know of anything else I might be missing?

Igor Azevedo said...

@Nguyen Hai dang

I had the same issue, add this to the process form:
input type='hidden' name='return_method' value='2'

This defines the method that is used to pass the params to success.php (1=GET, 2=POST). I think GET is the default but it wasn't working for me so I changed to POST and it now receives the data.

chitra said...

Can you Please tell is there any script which can convert smarty files to core php files instead of doing manually it is taking lot of time to change the code manually.If you have any solution Please let me know soon.........

waiting for your response.........

dskanth said...

I tried this demo.. working well, but when i tried the downloaded code, and customised it with my own details, i see that the payment is done.. but when it comes back to success.php, there is no parameter passed, and i receive the message: Payment Failed. Could not understand what is wrong.

Srinivas Tamada said...

Please provide me a solution for it.

ashutosh Mishra said...

Hi Srinivas,

i send a feed back to you regarding this tutorial . It was my mistake. It working fine with your $paypal_id ='sriniv_1293527277_biz@inbox.com' but when i use my pay pal id marut_1321421584_biz@1solutions.biz

It not work properly what is the issue. Can anything we do in my pay-pal sand box account setting.

in this case we not get item_number and amt and all other thing what is the problem .

Please provide me the solution for it.

My mail id is marut0210@gmail.com

Anonymous said...

Hi, In my case, the user is not redirected back to my website after payment is completed. Is there another back end soluction to get notified of a transaction? I'm trying to configure IPN but I cannot find it on sandbox anymore.

Payment Failed

sakkona said...

hi, Srinivas thanks for your tutorial.
it's great for me. First of all i had been the problem as @ashutosh Mishra too. now i can find the solution to redirect to the success.php page.
1. log in into Business mail
2. click on profile
3. Website payment preferences
in that, configure some points:
set Auto Return to On and type return URL address (e.g. http://localhost/paypal/success.php)
set Payment Data Transfer to On

I'm sorry if my English made you misunderstand.

When I do this, and paypal returns to the return url it does not post the info to the url like this "success.php?tx=270233304D340491B&st=Completed&amt=22.00&cc=USD&cm=&item_number=1"
it just goes to "success.php" why is that?

nice work.......

Nate said...

Is there anyway to make it auto-redirect to the success page? Right now, the only way for their purchase to be added to the database is IF they actually click return to the website.

Nate said...

I actually figured out the previous redirect issue, needed to change something in my paypal settings. Now I am noticing none of the parameters are sent with the success.php so all of the info being input into the database is blank or 0. Any way to fix this so it gets the actual data?

Anonymous said...

Awesome!!!!! I never see on the web like this..!

Anonymous said...

It's excellent Srinivas.


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 subtab.
The Profile Summary page appears.

Under the Selling 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.

i had the same issue with paypal not auto returning or getting data about transaction.

if you log into your sandbox Seller account. click on profile and go to 'selling preferences' then in the list click on 'Website Payment Preferences' in here you have a few options, you need to set Auto Return to ON also make sure Payment Data Transfer is set to ON - this will give you the transaction id, the amount etc.

Hi All,

Please let me know the fix for this issue.

Issue : Paypal is not returning tx,st,amt,cc,item_number,

In other words it route correctly to success.php without returning above mentioned parameters

We can not process this transaction because there is a problem with the email address provided by PayPal PayPal trade. Contact trade to solve the problem. If this payment goes to an eBay listing, you may contact the seller using the link "Ask seller a question" page of the advertisement. Once you have the correct email address, payment can be made at www.paypal.com.
