PayPall - return success variables

[Nightcat]

Hi guys

If anyone developed for PayPal payment system, may be you could point me in the right direction

I am making a site which has a payment button that sends a user to the PayPal site.

But I need to create a way for some feed back to know whether the transaction has been succesful or not.

do you know any tutorial on how to do that?

have you looked at the paypal developer's guide? it all depends on what API you're using.

Well It goes in to PHP sitting on top of Windows

Here's the button code which takes the user to the PayPal page:


echo'<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="business" value="admin@tidalwaveuk.co.uk">
<input type="hidden" name="item_name" value="'.$item_name.'">
<input type="hidden" name="item_number" value="'.$order_id.'">
<input type="hidden" name="amount" value="'.$amount.'">
<input type="hidden" name="return" value="http://callback.php">
<input type="hidden" name="cancel_return" value="http://cancel.php">
<input type="hidden" name="no_shipping" value="0">
<input type="hidden" name="no_note" value="1">
<input type="hidden" name="currency_code" value="GBP">
<input type="hidden" name="lc" value="GB">
<input type="hidden" name="bn" value="PP-BuyNowBF">
<input type="image" src="https://www.paypal.com/en_GB/i/btn/btn_paynow_LG.gif" border="0" name="submit"
alt="PayPal - The safer, easier way to pay online.">
<img alt="" border="0" src="https://www.paypal.com/en_GB/i/scr/pixel.gif" width="1" height="1">
</form>';


I am still looking through the developers guide, but it proves rather difficult to work out :(

I've looked through this one

https://www.paypal.com/IntegrationCenter/ic_pdt.html

But still a bit confused about how can I read this data in (it's my first time developing with PayPal)

[chazzy]

i think you just use curl (or the like) once the user's already went through paypal.

After checking all I could, the way provided in the link I gave on the top seems to be the best one.Although it's prety longwinded :)

Search for "Paypal IPN PHP" and you will see plenty of examples and topics.
