Lifecycle
The process of an online payment with Mellat bank gateway consists of following steps:
-
Request for a new payment
-
Redirect user to the bank gateway page
-
Verify payment on callback page
Getting Started
To use the package for your payments you must instantiate the Gateway
class
and provide its configuration.
use MiladRahimi\PhpMellatBank\Gateway;
$config = [
'terminalId' => '...',
'userName' => '...',
'userPassword' => '...',
'callBackUrl' => 'https://example.com/payment/callback',
];
$gateway = new Gateway($config);
Request Payment
As mentioned above, a the first step you must request for a new payment. It can be done this way:
$refId = $gateway->requestPayment($amountInRial, 'Some optional description...');
This method would throws GatewayException
if it could not call the bank server api,
MellatException
if the bank response is something other than 0 (success).
MellatException
holds the bank response in its message.
If there was no error it would returns the RefId
.
Redirect to Gateway
Now that you have gotten the RefId
you can lead user to the bank gateway.
To do this you should display an html form like this:
<form action="$bankGatewayUrl" method="post">
<input type="hidden" name="RefId" value="$refId">
<input type="submit" value="Pay">
</form>
The $bankGatewayUrl
is an url that bank provides for you
but you can get it from a Gateway
instance this way:
$gateway->url()
Verify Payment
User completes the payment in bank gateway
then bank redirects him to the callback you have provided in the configuration,
it also sends some parameters to the callback with POST
method.
Your callback url must verify the payment.
use MiladRahimi\PhpMellatBank\Gateway;
$gateway = new Gateway($config);
$refId = $gateway->checkPayment();
if($refId != false) {
$bankResult = $gateway->verifyPayment();
}
checkPayment()
method would return $refId
or false
if there were any error.
verifyPayment()
method would return the bank response as an instance of BankResult
class,
it throws InvalidResponseException
if the request is not valid (might not from the bank),
GatewayException
if it cannot call the bank server api,
MellatException
if the bank response is something other than 0 (success).
Exceptions
GatewayException
: It'd be thrown when there were a problem on calling bank server APIs.MellatException
: It'd be thrown when bankResCode
is not0
(success). It holds the real response in its message.InvalidResponseException
: It'd be thrown in verification level (callback url) when the parameters are not valid. This problem usually occurs when someone/something other than bank calls your callback url.
