Custom payment gateway - need help with IPN

[brendonhatcher]

Hi

VCS is a South African payment gateway.
They recently created a payment plugin for VM2.

I am having difficulties working out how the successful payment will update the order in VM2 to "paid".

Reading on the forum, I found /index.php?option=com_virtuemart&view=pluginresponse&task=pluginnotification&tmpl=component as a possible passback url

The VCS terminal makes provision for a "success" and "failure" URL.
However, these do not allow parameter URLs, so I can use the above example.

Any ideas?

Regards
Brendon

Hi,

Create a file called for example notify.php, add the following code, and place it it the root folder:

Code Select Expand

$_REQUEST['option'] = "com_virtuemart";
$_REQUEST['view'] = "pluginresponse";
$_REQUEST['task'] = "pluginnotification";
$_REQUEST['tmpl'] = "component";
require_once("index.php");
?>

and in VCS : give for the URL the name http://yourdomain.com/notify.php

Thanks for this alatak

Code Select Expand

$_REQUEST['option'] = "com_virtuemart";
$_REQUEST['view'] = "pluginresponse";
$_REQUEST['task'] = "pluginnotification";
$_REQUEST['tmpl'] = "component";
require_once("index.php");
?>

Hi, on trying this, it works, but the URL of my site keeps saying http://www.misite.com/notify.php, it is possible to reload the page so it changes to the correct url? IE: http://www.mysite.com/index.php?option=com_virtuemart&view=pluginresponse&task=pluginnotification&tmpl=component

Thanks a lot!

PS: Just in case someone needs it. In my case, I prefer to have the notify.php on the plugin folder, so in joomla 1.5 and joomla 2.5 the paths are different, so to keep it working, i added this simple code.

Code Select Expand


if (file_exists("../../index.php"))
    require_once("../../index.php");
else
    require_once("../../../index.php");

Hi,

Yes you are rigth, it is better to have the file in the plugin.
You can also use this constant JPATH_SITE.

You can also use this constant JPATH_SITE.

I don't think so, because this file is not knowing where index.php is and also is not having access to joomla global vars.

Anyway, is it possible to solve the URL issue? (http://www.misite.com/notify.php => http://www.mysite.com/index.php?option=com_virtuemart&view=pluginresponse&task=pluginnotification&tmpl=component)

Thanks!

Hi, i think i have solved the redirect issue with this little piece of code.

Code Select Expand

$topic=$_GET["topic"];
$id=$_GET["id"];

if (file_exists("../../index.php"))
    header("Location: ../../index.php?option=com_virtuemart&view=pluginresponse&task=pluginnotification&tmpl=component&topic=$topic&id=$id");
else
    header("Location: ../../../index.php?option=com_virtuemart&view=pluginresponse&task=pluginnotification&tmpl=component&topic=$topic&id=$id");

But when redirected, the page gets completely blank! but the method plgVmOnPaymentNotification gets called ok!

Is that normal, to get a blank page on calling plgVmOnPaymentNotification?

thanks!

PS: using VM 2.0.6

Hi,

Yes it is normal to get a blank page. The task pluginnotification is used for server to server notification, and should not ave any output.
If you need output, you can use task pluginresponsereceive.

[razor7]

Great!, that means i haven't broken anything!!!

Best regards!

Hi, just one more question.

What sould i return if something goes wrong in the IPN check? Actually I'm returning "false" but there is no documentation about return value of plgVmOnPaymentNotification()

[alatak]

Hi,

the plugin itself should decide what to do when the IPN is wrong. You can decide to change the order status, or to remove the order. You choose.

[razor7]

Hi, I know that, I mus decide in that function what to do with the order, but I mean wich return value should return to VM, if something needs to be returned.

[alatak]

Hi,

nothing needs to be returned.

[razor7]

Great!

Thanks a lot!
