I have a PHP script of a payment gateway (Cashfree). In this script, there are some variables such as: appId, orderId, orderAmount, orderCurrency, etc and also the details of the customer who is paying money. I have uploaded this script into my server. Now I want to provide the data in all the variables from my app using Post Text. But I am not able to figure it out. Can someone help me with this?
Here is the script:
<!DOCTYPE html>
<html>
<head>
<title>Cashfree - Signature Generator</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body onload="document.frm1.submit()">
<?php
$mode = "TEST"; //<------------ Change to TEST for test server, PROD for production
extract($_POST);
$secretKey = "TEST974175fd587548b3ff8a3b2648f6bf";
$postData = array(
"appId" => $appId,
"orderId" => $orderId,
"orderAmount" => $orderAmount,
"orderCurrency" => $orderCurrency,
"orderNote" => $orderNote,
"customerName" => $customerName,
"customerPhone" => $customerPhone,
"customerEmail" => $customerEmail,
"returnUrl" => $returnUrl,
"notifyUrl" => $notifyUrl,
);
ksort($postData);
$signatureData = "";
foreach ($postData as $key => $value){
$signatureData .= $key.$value;
}
$signature = hash_hmac('sha256', $signatureData, $secretKey,true);
$signature = base64_encode($signature);
if ($mode == "PROD") {
$url = "https://www.cashfree.com/checkout/post/submit";
} else {
$url = "https://test.cashfree.com/billpay/checkout/post/submit";
}
?>
<form action="<?php echo $url; ?>" name="frm1" method="post">
<p>Please wait.......</p>
<input type="hidden" name="signature" value='<?php echo $signature; ?>'/>
<input type="hidden" name="orderNote" value='<?php echo $orderNote; ?>'/>
<input type="hidden" name="orderCurrency" value='<?php echo $orderCurrency; ?>'/>
<input type="hidden" name="customerName" value='<?php echo $customerName; ?>'/>
<input type="hidden" name="customerEmail" value='<?php echo $customerEmail; ?>'/>
<input type="hidden" name="customerPhone" value='<?php echo $customerPhone; ?>'/>
<input type="hidden" name="orderAmount" value='<?php echo $orderAmount; ?>'/>
<input type ="hidden" name="notifyUrl" value='<?php echo $notifyUrl; ?>'/>
<input type ="hidden" name="returnUrl" value='<?php echo $returnUrl; ?>'/>
<input type="hidden" name="appId" value='<?php echo $appId; ?>'/>
<input type="hidden" name="orderId" value='<?php echo $orderId; ?>'/>
</form>
</body>
</html>
Also, is the script setup properly?
