Multi page form: back button error, how to handle session

First, congratulations and many thanks for your tremendous plugin! I've been through many tasks with it, and it makes a great job!

I try to set up a multi page form, and the only problem for me is the "page expired" problem: when I hit the back button, I get the "page expired" error.
I try this with your multi page form demo in my joomla and it produces a new session id, but it doesn't transfer the session id as a GET variable like in your online demo: http://greyhead.org/index.php?option=com_chronoforms&tmpl=component&chronoform=test_form_multipage.
Is the GET variable neccessary at all? Do I have to read and use it?

I've done a lot of research in this and other forums, really. I know, I don't have to use Data to Session and vice versa in v5. In fact, I just try to run your demo with the browser-side "go back/forward" option.

Any help would be greatly appreciated!
Thanks in advance,
Max

Hi mistermotomax,

V5 comes with demo forms built in, just clock the "demo forms" button in the forms manager and inspect the multi page form.

Hi Max,

thanks, but I thought that this might be misunderstood: I already use your Multi Page Form demo in my Joomla. It is exactly this form which I'm starting with and which already has the problem.

You can test it here:

Sorry, I missed this, well, you should use a link instead of a back button then, this will not have the same problem!

You can get the previous page link by copying it from the browser's address bar.

You mean, the user can't use the browser's back button?
It works with the cf_sid GET variable in the following Greyhead demo, doesn't it?

Thanks a lot in advance,

I really wonder how you managed to achieve that the user can switch between the form pages with the browser's back/forward buttons in greyhead's multi page form: http://greyhead.org/index.php?option=com_chronoforms&tmpl=component&chronoform=test_form_multipage
Normally a POST form doesn't allow this without tricks...

Hi mistermotomax,

The multi-page demo just has standard Submit buttons. The browser buttons working is not a deliberate setting that I recall.

Hi Bob,

thanks for your reply! Would you share with me how it works, then?

Best regards,

Hi Max,

No idea - there's nothing special there that I can see.
