如何在我的成功页面上知道客户端paypal交易是否成功

Question

On my order page, I'm using this form:

<input type="hidden" name="item_number" value="<?php echo $refNumber; ?>">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="business" value="<?php echo $paypal_email; ?>" />
<input type="hidden" name="currency_code" value="USD" />
<input type="hidden" name="return" value="<?=$_SESSION["web_site_url"]?>/payment_success.php?OrderID=<?=$refNumber;?>" />
input type="hidden" name="amount" id="amount" value="<?=$product_vals["discount_prize"]?>" />
<input type="hidden" name="item_name" id="item_name" value="<?=$product_vals["name"]?>" />

now I want a sample code for my payment_success page from that i came to know whether paypal authenticate the client payment or the client's payment is success of not.. so that i can proceed to next step of gathering information from client.

I have read the Paypal docs but unable to learn useful from them. help me out to solve this problem.Moreover i also want to get the paypal email of client and transaction id / payment_success variable (that is true/false) so that i will help me to identify the payment is succesful or not..

Thanks in advance.

You can use paypal class by Micah Carrick. This is pretty clear class which support notify URL, return URL and success URL. You dont need to use any form or something but just use this class and let this class to do your job. sample code is:

$p = new paypal_class;   
$p->add_field('business', $paypal_email);
$p->add_field('return', $add_fund_url.'/success.php');
$p->add_field('cancel_return', $add_fund_url.'/cancel.php');
$p->add_field('notify_url', $notify_url );
$p->add_field('item_name', $item_name);
$p->add_field('item_number', $item_number);
$p->add_field('custom',$custom_field);
$p->add_field('amount', $amount);
$p->add_field('no_shipping', '1');
$p->submit_paypal_post(); // submit the fields to paypal
