Maybe when he wanted more infos he meant to specify in which part of the code you need to put that and things like that...It would be great for us to help you with your code if you could post a pseudo code.
However as he said this is the sintax for GET
www.somesite.co m?var1=2 and so on...

Hi Yogesh,
You can Send a hidden form field named return with theOther form elements

[PHP]
$paypal_site_ur l='http://www.thescripts. com/thanks.php';
<input type="hidden" name="return" value="<?=$payp al_site_url?>">


[/PHP]

Thanks for your input Ajaxrand,
Let me explain the scenario.
I a working on a site where user updates details in a form and data gets updated in the database.

1. User Updates form with his unique UserID
|
2. Data goes in database
|
3. Column Payment_status from database is marked as "Not Done"
|
4. User is redirected to Paypal site
|
5. User makes the payment
|
6. Paypal redirects to my site on payment completion
|
7. Payment_Status column is marked as "Done" for that particular UserID

Now what I want to do is when I redirect(step 3) the site to paypal I also want to set Return parameter with parameter UserID.

So when user comes back to my site I can use the UserID to change value in database.

I read somewhere about rm parameter. But not sure how to use that.

I am new to payment gateway. so please help.

Thanks,
Yogesh

rm is stands for Return Method

$paypal_return_method="2"; //1=GET 2=POST
<input type="hidden" name="rm" value="<?=$paypal_return_method?>">
 

You can set either GET or POST method. Then once user press the complete button from Paypal side you can retrieve the Completed transaction info back to your site.

To the page that I mentioned in my ealier post.

<input type="hidden" name="return" value="Complete_URL_to_the Success_page.php">
 
 

Here at success.php (IF rm is POST), You can print back the completed transaction details to the customer.

 
<?=$_POST['txn_id']?>
// This is only the transaction ID
// There are Lots like this refer to Paypal web site for more
 

But issue is here,some times user might NOT press the button to merchant web site.
In that case you can use IPN functionality.
This is set by

<input type="hidden" name="notify_url" value="complete_URL_to_IPN.php">
 

Sending this form field to paypal. Then once payment made this url will fire without pressing return back to your site.

When you send this notify_url you can send the User ID to Paypal and get it back by GET request.

<input type="hidden" name="notify_url" value=" http://www.site.com/ipn.php?userid=1001">

Hi I tried the notify_url but it didnt work can you see if I am doing any error.
or do i need to change any any setting in paypal site to activate notify_url


Here is my html code for the form
=============== =============== =============== ===

<input type="Hidden" name="cmd" value="_xclick">
<input type="Hidden" name="business" value="[e-mail]">
<!-- Allow customer to enter desired quantity -->
<input type="Hidden" name="undefined_quantity" value="1">
<input type="Hidden" name="item_name" value="Registraion">
<input type="Hidden" name="item_number" value="">
<!-- No currency_code variable has been specified, so monetary amount is assumed to be USD -->
<input type="Hidden" name="amount" value="10">

<input id=PasswordVerify style="WIDTH: 165px" tabindex=3 type=text maxlength=15 name="Phone">
<input id=EMail style="WIDTH: 165px" tabindex=4 name="Email">
<input type=submit value=Submit Now name=Authorize onClick="updatevaluesonsubmit()">
 

<script language="JavaScript" type="text/JavaScript">
function updatevaluesonsubmit() 
 
notify_url = "http://mysite.com/Payment-Complete.php?";
notify_url = notify_url + "Name=" + frm.Name.value;
notify_url = notify_url + "&Phone=" + frm.Phone.value;
notify_url = notify_url + "&Email=" + frm.Email.value;
notify_url = notify_url + "&Country=" + frm.Country.value;
notify_url = notify_url + "&Product=" + frm.Registraion.value;
notify_url = notify_url + "&Amount=" + frm.amount.value;
frm.notify_url.value = notify_url;
</Script>

When user clicks on submit I am running updatevaluesons ubmit javascript to update notify_url field (I checked this and it works fine)
then it opens paypal site but when user makes payment it does not run Payment-Complete.php.

here is the code of Payment-Complete.php to send email. but it does not send email

when user makes payment it does not run Payment-Complete.php.

If you not getting a mail the problem is with your mail script. but note that you cant see the page(s) anyway (payment_comple te page, Thankyou page ).Its Completly hapening on the server side.
Server-Server Comunication
when Calling from client to server only you can see the page.

Read my previuos post to find out the diferences between
return
notify_url
