Forums

I posted earlier about this issue, but now I have learned so much more, which makes it a different problem.

I use Chronoforms with Virtuemart and Bixie module. Everything works fine, except one thing.

When someone places a order, the form data is stored as a parameter in VM with a form-id. This form-id, with the data from the form, is stored in a table from bixie.
With the form-id as parameter, the data is printed in the order confirmation.

But when someone places a order, this form-id data (from the chronoforms form) is also in the cache of joomla (eventhough caching is off). So the next user gets the data (form-id) from the previous user, untill I clear the cache of joomla.

Did anyone have problems with formdata being stored in cache?
Does anyone have an idea on how to fix this?

Hi creezi,

I'm finding it very difficult to understand where and how this data is being stored. The Joomla! cache is off, ChronoForms doesn't cache anything. Is this something that is resulting from Bixie or VirtueMart?

Hi Bob,
Thanks for your reply. I think it has to do with the bixie module. I don't understand it at all.
I have been looking at this issue for almost two weeks and don't understand. After I cleared the cache, the first order goes well, after that the next order is a copy of the first untill I clear the cache again. It doesn't matter if the order is from a different computer, or even ip address.

Perhaps it is somewhere in the module php. After working on the new site for three months straight, everything is finished, only this final issue is killing me.😉
Perhaps someone knows how to solve this issue, I would be so grateful!!
Thanks in advance for everyone who will take a look.
Btw, the Bixie module developer is not responding to the forum or support questions, unfortunately!
Regards,
Creezi

I am a step further, sorry for changing the problem over and over.
I have tested with the cache plugin on and off. When the plugin is off, the order placing goes well, but in the next step in the cart, my added products are gone.

So I do need the caching to be on. I could've sworn it was off, during my last tests, but obviously it wasn't. My apologies. I have been testing for so long that it is confusing which steps I have taken.

Conclusion; it must be a combination of Bixie with Virtuemart issue and definitely not a chronoforms problem. I will ask on the virtuemart forum. But in case you have any suggestions, please say so. Thanks in advance.
