Worldpay gateway added

Wednesday 04 February 2004 10:48:13 am

Hi,

I am glad you got the WorldPay extension working :)

The callback feature takes the content from your shop site and displays it through its own engine. This is to give the customer the sucessful or unsecessful message with a treansaction message.

Just to check that the extension is working

* Does the order appear in the Admin order screen? If it is sucessful it will do.

I am assuming that the order has been completed sucessfully, the problem you might be having is that you cannot include Javascript in the Worldpay screens. This is a secuirty precuation by Worldpay.

You will notice that in the callback.tpl the location of the css is set as local to the worldpay urls.
<link href="/i/0000/favicon.ico" rel="shortcut icon" />
<link rel="stylesheet" type="text/css" href="/i/0000/core.css" />
<link rel="stylesheet" type="text/css" href="/i/0000/troy.css" />
This is where 0000 is your worldpay account.

So you can include images etc in your site... but alas JavaScript is a nono.

Try your callback.tpl page without Javascript and see if the error occurs.

Let me know

ok,

The first thing to check is theat your site can be accessed by the Worldpay site. i.e. it must be a public domain. If this is teaching you to suck eggs, I apologise :(

The next is to check that the Worldpay server is calling back to the correct page. I think this might be your problem as thear i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) in the message is Javascript so it must be getting it from somewhere.

After you are sure you are calling the right page, use the eZ publish HTTP variable routine to display all the values sent back to you by Worldpay as they enable you to test the system. This will elt you know what values are coming back to the Callback page. If you follow the commented PHP in callback.php you will see all the check that are carried out and if you enable debug you will be able to see exactly where the problem lies.

I hope this helps

ok, sounds like a real mystery, I like those...

The first thing to do is to test locally and remove WorldPay site form the equation, waiting 24 hours for results sounds like working with Punch cards, we can't have that.

Here is a routine that you can run locally against your site. You are bascially recreating the WorldPay callback routine.
To make this work you need to view the source from http://mydomain.com/shop/checkout/ and take the values from it. You need to then copy these values and replace the ones in the code included here. When you run this routine it will enable you to see all the issues with your code site and checks (Make sure you turn debug on).

I'll pop this HTML in pubsvn if it helps.

Let me know

Hi,

the template used by callback.tpl is defined in callback.php

$Result = array();
$Result['pagelayout'] = 'wp_pagelayout.tpl';
$Result['content'] =& $tpl->fetch( "design:callback.tpl" );
return true;

We define it here specifically for this reason :) So you can have a page without Javacsript and locally accessed images.

Hope this helps

Hi,

You do not need to reinstate the session this session issue is already handled by callback.php, you will notice that the Worldpay extension gets passed the Session ID.

As for permissions, anonymous should not have full permissions all you need is to add

Give anonymous access to the worlpday module
worldpay * *

This will give the WorldPay servers access to call it.

Hi Starla,

It looks like we are almost there :)

The records stored in the worldpay db are for transaction use only. So the system is designed to remove them when a payment transaction has completed sucessfully. The reason why the record in the Worldpay db is deleted is because a full transaction has occured.
The idea is to extend the worldpay module to include reporting for failed transaction i.e. the ones left in the worldpay db. There is no need to to store this data beyond that as eZ publish has all the order information you need in it workings. So you can view order information using the admin orders screen. Of course feel free to write some reporting modules and we can add them the the GPL worldpay module. We are working on a couple of commerce sites at the moment using this module so may well extend it beyond it oringial brief for the the ealry eZ 3 commerce sites we did.

I hope this helps

Yes the Installation ID is checked in
if ( $http->hasVariable( "instId" ) )
{
$inst_id =& $http->variable( "instId" );
return true;
}
else
{
// This is not a call from worldpay
eZDebug::writeDebug( "Worldpay", "This installation ID does not match" );
return false;
}

It ensures you are paying the money into the right WorldPay account, this is useful when you have more than one installation and you copy code around. Your right though the Installation ID should not be hard coded, Ill add it to the todo list.

Also, we will be releasing an update to the WorldPay module that enables it to work with multiple currencies rather than the signle hardcoded one at the moment. This has been tested and has gone live so will get posted to SVN soon.
Another module on our todo list is a generic RIPE country code module, to make life a little easier...

Hi Paul,

I'm working on a paynet extension which too will be triggered at shop | checkout | before since the after trigger doesn't work as we've discussed earlier.

However, this results in the basket not being cleared and the order not being stored which I supposed happens during the checkout process.

How did you get around this problem?

Thanks in advance !

Hi Tony,

Thanks for the tip. I''ve actually already done that. But how did you get the order stored (and the order confirmation email sent out)?

Hi,

I have the same problem as described above, that i can't see the event/worldpay event i my dropdown, when i try to create a workflow. I have tried and tested the three reasons you have described to this problem, but i still cant make it work.
Do you have any suggestions as to what might be the problem? I am currently using eZ 3.4.1.

Sincerely

Bo Henriksen
