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.
Download Script 
Live DemoSample database design for Payment system. Contains there table users, products and sales.
Users
CREATE TABLE `users` (
`uid` int(11) AUTO_INCREMENT PRIMARY KEY,
`username` varchar(255) UNIQUE KEY,
`password` varchar(255),
`email` varchar(255) UNIQUE KEY,
)
`uid` int(11) AUTO_INCREMENT PRIMARY KEY,
`username` varchar(255) UNIQUE KEY,
`password` varchar(255),
`email` varchar(255) UNIQUE KEY,
)
Products
CREATE TABLE `products`
(
`pid` int(11) AUTO_INCREMENT PRIMARY KEY,
`product` varchar(255),
'product_img` varchar(100),
`price` int(11),
`currency` varchar(10),
)
(
`pid` int(11) AUTO_INCREMENT PRIMARY KEY,
`product` varchar(255),
'product_img` varchar(100),
`price` int(11),
`currency` varchar(10),
)
Sales
CREATE TABLE `sales`
(
`sid` int(11) AUTO_INCREMENT PRIMARY KEY,
`pid` int(11),
`uid` int(11),
`saledate` date,
`transactionid` varchar(125),
FOREIGN KEY(uid) REFERENCES users(uid),
FOREIGN KEY(pid) REFERENCES products(pid)
)
(
`sid` int(11) AUTO_INCREMENT PRIMARY KEY,
`pid` int(11),
`uid` int(11),
`saledate` date,
`transactionid` varchar(125),
FOREIGN KEY(uid) REFERENCES users(uid),
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
Step 3
Here I have created two accounts Buyer (personal) and Seller (merchant/business) 
products.php
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.
<?php
session_start();
require 'db_config.php';
$uid=$_SESSION['uid'];
$username=$_SESSION['username'];
$paypal_url='https://www.sandbox.paypal.com/cgi-bin/webscr'; // Test Paypal API URL
$paypal_id='your_seller_id'; // Business email ID
?>
<body>
<h2>Welcome, <?php echo $username;?></h2>
<?php
$result = mysql_query("SELECT * from products");
while($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']; ?>'>

<input type="image" src="https://paypal.com/en_US/i/btn/btn_buynowCC_LG.gif" name="submit">
</form>
<?php
}
?>
</body>
success.php
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
<?php
session_start();
require 'db_config.php';
$uid = $_SESSION['uid'];
$username=$_SESSION['username'];
$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'");
$row=mysql_fetch_array($sql);
$price=$row['price'];
$currency=$row['currency'];
//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')");
if($result)
{
echo "<h1>Welcome, $username</h1>";
echo "<h1>Payment Successful</h1>";
}
}
else
{
echo "Payment Failed";
}
?>
session_start();
require 'db_config.php';
$uid = $_SESSION['uid'];
$username=$_SESSION['username'];
$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'");
$row=mysql_fetch_array($sql);
$price=$row['price'];
$currency=$row['currency'];
//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')");
if($result)
{
echo "<h1>Welcome, $username</h1>";
echo "<h1>Payment Successful</h1>";
}
}
else
{
echo "Payment Failed";
}
?>
Positive approach
cancel.php
Paypal API cancel_return file.
<?php
session_start();
$username=$_SESSION['username'];
echo "<h1>Welcome, $username</h1>";
echo "<h1>Payment Canceled</h1>";
?>
session_start();
$username=$_SESSION['username'];
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.
$paypal_url='https://www.sandbox.paypal.com/cgi-bin/webscr';
to
$paypal_url='https://www.paypal.com/cgi-bin/webscr';
to
$paypal_url='https://www.paypal.com/cgi-bin/webscr';
nice, i have some project that needed to integrate with PP, and you make this tuts :)
ReplyDeletegreat :)
nice !! :-) ... you are a genius ... you always make complicated things easier ...
ReplyDeleteHow 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.
ReplyDeleteWell done. Thank you guy.
ReplyDeleteHi srini, nice tute as usual..:) is creating test account on paypal free or payable?
ReplyDeleteSrinivas, I'm curious about your database graph. What do you use when designing databases?
ReplyDeleteHey Great tutorial, Srinivas, thank you from Perú.
ReplyDeleteOmg.... Asians rock!
ReplyDeleteGreat post Srinivas... we like these kind of innovative posts. Thanks a lot.
ReplyDeleteSQL Injection, no verification that a call to success.php actually came from PayPal (and is valid)...words fail me.
ReplyDeletethis tutorial ROCKS! thank you very much dude :D
ReplyDelete@Dan Mysql Workbench for database ER diagrams.
ReplyDeletewaw..thanks for sharing Srinivas..:)
ReplyDeleteYou 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:
ReplyDelete<--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.
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
ReplyDeletehi,
ReplyDeletei 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...
Hey Srini,
ReplyDeletei got the same error like ashish...
Nice post. I solved my problem very well.
ReplyDeleteThanks
Modified 'success.php' file code. Re-checking the product price and currency details
ReplyDeletehi srini, my question is .. in step 1 we need to register for the sandbox account.. is it paid account ??
ReplyDelete@Sreevathsa
ReplyDeleteIt's free just test account
hey Sri its not TEXT ACCOUNT its TEST Brother I think a little typo mistake is there.. :)
ReplyDeletei 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?
ReplyDeleteFor me its not safe, also the return url dont have transaction id for me.
ReplyDeleteVery Handy tuts :)
ReplyDeleteitem_number. Paypal data success.php?tx=270233304D340491B&st=Completed&amt=22.00&cc=USD&cm=&item_number=1
ReplyDeletewhat $_GET[???], is Quantity???
its post is nice but why are you using IPN for update database.
ReplyDeletePlease advice how to use this tutorail to protect digital file. if success able to download file if not protected digital file.
ReplyDeleteHi. 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
ReplyDeleteWhats the problem here? Or is it only a sandbox problem?
Thanks.
nice info..
ReplyDeleteDear Srinivas Tamada,
ReplyDeletei 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.
Same with Nguyen Hai Dang
ReplyDeleteSanbox new accounts success redirection problem.
ReplyDeleteIt 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.
ReplyDeleteI 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?
@Nguyen Hai dang
ReplyDeleteI 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.
Hi,
ReplyDeleteCan 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.........
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.
ReplyDelete@dskanth

Hi,
ReplyDeleteNice tutorial it work properly when i set my return url: http://demos.9lessons.info/paypal/success.php.
But when i change it with my url for ex:
return url: http://localhost/paypal/success.php.
it not work properly i am also not getting any item_no value on the success.php file when i echo the query :
"select product,price,currency from producst where pid='$item_no'"
it give pid=''
what is the problem .
Please provide me a solution for it.
Hi Srinivas,
ReplyDeletei send a feed back to you regarding this tutorial . It was my mistake. It working fine with your $paypal_id ='[email protected]' but when i use my pay pal id [email protected]
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 [email protected]
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.
ReplyDeleteWarning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\paypal\success.php on line 15
ReplyDeletePayment Failed
hi, Srinivas thanks for your tutorial.
ReplyDeleteit'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.
really good to see this blog...

Hi Seyha
ReplyDeletePaypal sandbox updated new sample biz id not redirecting properly.
Hi, I used it but it live for Paypal Send box but it only show
ReplyDeleteThanks for your order page of Paypal, not redirect to success.php and therefore does not insert record into sales table.
Hi, your code helped me to start my code with.
ReplyDeleteFacing a problem! What if a user clicks some other link (like: show my account details); our site will not be notified about payment and the payment will b deducted from user account and credited to store account. BUT our database will have no entry against it.
Any solution??
OMG, you save my time, thanks. love this tutorial.
ReplyDeleteHi Srinivas Tamada,
ReplyDeleteI 'm Ok all of the steps,but in success.php it show me "Payment Failed" and it does not save sales table. Why? . That's a problem and please explain it. Thanks in advance.
Hi!
ReplyDeleteso the redirection problem is there in the sandbox accounts
but is the redirection problem also in the real accounts...
can some confirm this..
@Srinivas: awesum blog... really helped..
\m/
Hi Srinivas,
ReplyDeletewhen i used your paypal id , paypal will redirect to success page(all working fine) but when i use my paypal id it's not redirect! so how to update my database?
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"
ReplyDeleteit just goes to "success.php" why is that?
@Gurav, this is something I also want to know
ReplyDeleteIs it possible to pay the amount to two account at a single time?
ReplyDeleteI mean to say that when a person pays amount then his amount will be divided in two parts 95% of amount to the actual payment receiver and 5% to a default user(me).
need to explain more clearly dear
ReplyDeleteI am getting the following error
ReplyDeleteThis recipient is currently unable to receive money
What should i do
Hay First of all thanks dude...
ReplyDeleteI try your demo code and its work properly but in final step i can't redirect on sucess.php pls replay fast...
Thanks again..
Hi Srinivas Tamada,thank u for update
ReplyDeleteI 'm Ok all of the steps,but in success.php it show me "Payment Failed" and it does not save sales table. Why? . That's a problem and please explain it. Thanks in advance.
nice work.......
ReplyDeleteIs 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.
ReplyDeleteI 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?
ReplyDeleteAwesome!!!!! I never see on the web like this..!
ReplyDeleteIt's excellent Srinivas.
ReplyDelete@Nate:
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.

ReplyDeletei had the same issue with paypal not auto returning or getting data about transaction.
ReplyDeleteif 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.
forgot to say thanks @Srinivas Tamada :D
