WorldPay Module version 2.0 - Support thread

[niknfa]

Hi,

If you were replying to me I'm afraid it's not that. I've tried various permutations of the callback URL and I've now put it back to what it should be (and which was working for 9 months):
http://<wpdisplay item="MC_callback">

From scanning various pages on the topic it seems that various PHP settings, particularly to do with sessions, might affect the 302 error. It seems to me that when Worldpay issues the callback (which it does, and with the correct callback pw) Zen Cart has forgotten who it's talking about and therefore redirects it to the hacker response page.

I've finally had some word from our host and they've only sent me a link to the servers config page - phpinfo.php

I've looked at the section on sessions, but basically don't have a clue what most of it means.... can someone send me their PHP 5.3 info page in a PM or something so that I can compare??

I've been told I might be able to make changes via a php.ini file - does anyone have experience of doing that?

Thanks,
Nick

First check that in Configuration > Sessions the following are all set to false:
Force Cookie Use
Check SSL Session ID
Check User Agent
Check IP Address

If it's still not working after that look at phpinfo.php and check that the following are turned off:
register globals
magic quotes
session.use_trans_sid

That's just my two pence. No doubt there are many other settings that might be involved.

Thanks for those that have replied - I've managed to crack it finally! (With absolutely bugger all help from our hosts Hostpapa.)

Eventually I did get them to forward a phpinfo page for the new server and also one from a server yet to have the upgrade. After comparing the two I noticed that the only relevant setting that was changed was
session.use_only_cookies
which used to be off and with the the PHP upgrade to 5.3 it by default gets set to ON.

As it is CGI-running server (I learnt the odd thing or two!) I uploaded a php.ini file in the root of the server with the sole line being:
session.use_only_cookies = off

This immediately fixed it and the callback was coming through, orders into ZC, confirmation email to customer from ZC etc.

I'm glad it's over, just wished the hosts (who you would think would be knowledgeable about the possible solutions) would have responded sooner!

btw, I did check those session settings in ZC first.
Also, to anyone frantically doing a google search, like I've been doing the last 5 days, I am on ZC 1.3.9b and Worldpay for ZC 2.10

This worked perfectly for me, we moved servers and noticed that the payment response was giving the error:

NOT OK, recevied HTTP status: 302

I could not get the php.ini method to work so I added the following line to my .htaccess php_value session.use_only_cookies 0. I then noticed that in my phpinfo went from session.use_only_cookies On to Off.

I hope this helps someone.

Hi all,

OK, so seem to have an issue with the installation, if someone could please direct me.

I am using Zen Cart version 1.3.9f, with Worldpay v 2. I have added all the info as per the install instructions, I have created my Payment Response Password and MD5 secret for transactions password, added my Payment Response url (http://<wpdisplay item="MC_callback"), added the passwords to my Zen Cart Worldpay installation, added a php.ini file with session.use_only_cookies = off, and I have PHP version 5.2.17.

When I place the order through the site (www.blackorangevintage.com), I get to the Worldpay screen where I can add my card details, it then takes the payment and give me a success screen (Thank you, your payment was successful
Merchant's Reference: *******
WorldPay Transaction ID: *********). I get the confirmation e-mail from Worldpay, no e-mail from Zen Cart and no order in Zen cart. I have been looking at the posts and have tried various things but cannot seem to make it work. Please, please help!

Is anyone using Worldpay with zencart v1.5 with PHP 5.3. I'm currently upgrading but have had a problem with worldpay itself when my host changed from PHP 5.2 to 5.3, had to put in an override to allow the site to carry on as PHP 5.2 but this option will not be available in a couple of weeks.

[BTaylor351]

Found the answer finally in one of the above posts by niknfa. Managed to get a copy of the hosts phpinfo and compared the 5.2 with the 5.3 version, found the session.use_only_cookies had changed.

Put in an overriding php.ini and its now working fine

Hi i am new to this and have exactly the same problem with worldpay and have exactly the same problem i have located my .htaccess file please can you tell me how to add a line do i just add 'php_value session.use_only_cookies 0' underneath what is already there, i tried that and my website went down with an internal 500 error, do i need to add something before the line like brackets to make it work? i also don't know how to check my phoinfo on cookies, i have spent hours trying to resolve the worldpay issue and help would be greatly received.

Hi,

If you were replying to me I'm afraid it's not that. I've tried various permutations of the callback URL and I've now put it back to what it should be (and which was working for 9 months):
http://<wpdisplay item="MC_callback">...

No I wasn't replying to you specifically niknfa, just pointing out that, by default WorldPay sets the callback URL to <wpdisplay item="MC_callback"> (without the preceding http:// or https:// ) which will result in a callback failure.

WorldPay's callback always tries to return to an https connection irrespective of whether you enter http or https in the Payment Response URL so will result in security messages flagging up in the users browser if you don't have SSL installed. Ideally, for customer confidence and compliance with WorldPay's merchant T&C's your website should have an SSL certificate installed.

The WorldPay module normally worked 'out of the box' in earlier versions of Zen Cart, but additional security protocols in 1.39 versions seems to be causing issues with getting the integration set up.

For anyone having problems it's worth trying the following settings in the Integration setup at WorldPay:-

Payment response: checked
Recurring Payment response: checked
Enable Shopper response: checked
Suspension of Payment Response: not checked

Using the WP copy from the test integration to the live integration appears 'lose' or corrupt the password so always re-type (or copy paste) the matching Payment Response password from your Zen Cart store setup into the 'live' integration.

I've found that setting MD5 secret for transactions to on in most of my clients setup usually results in callback failure, so I always leave it empty and unused.

Hope this helps anyone having problems with the WP setup...

Hi all, well i read pretty much of these 60 pages!
My problem i only have with this mod, is that it times out?
Here is the email i received:

Our systems have detected that your callback has failed.

This callback failure means we were unable to pass information
to your server about the following transaction:

Transaction ID: 2064097426
Cart ID: b02c5f86f8941dac71bf2f3cbb7598b0
Installation ID: XXXXXX

Error reported: Callback to: http://www.cakekraft.co.uk/index.php...e=wp_callback: failed CAUSED BY Read timed out
Server Reference: mm2imsps4p:callbackFailureEmail-130046:MerchReq-377-42

Also, if you usually return a response page for us to display to the Shopper
within the time allowed (1 minute), this will not have been displayed.

RBS WorldPay will have displayed to the Shopper the response page file
(resultY.html or resultC.html) held for your installation on the RBS WorldPay
server. This will be your own custom version, if you have supplied one, or,
if not, the RBS WorldPay default version.

Please can someone help, as people are placing orders and it's not showing in Zencart.
Thank You.
Nic
