One-Page Checkout [Support Thread]

OPC's observer class (which performs the session-hash) doesn't include $_SESSION['shipping']['extras'] as being pertinent to the hash.

But if the condition was understood correctly, on the initial run through of the hash, wasn't $_SESSION['shipping'] not set to begin with? Thus the first cycle would not have that session variable and then when checking for the change, the extras key would be removed but now the shipping session variable would be present?

I say that because of the fix that appeared to work for the OP.

OPC's AJAX handler sets the session-based shipping. If the overall value isn't set, there'd be a redirect back to the main page prior to the hash.

I did some tests on the order lookup page (order_status) from OPC. I noticed that, sometimes it will show some errors.

Here are what I found:

In Chrome, open a new Incognito Windows, enter order_status URL directly (/index.php?main_page=order_status). Enter something in order number and email (no matter they are valid or not). Then click "Continue" button. It will always show "Whoops! Your session has expired./Login Time Out". This error page will be shown up by 100% chances.

Then, if I use Go Back button on the browser to go back, enter something in the order number and email then continue, "Whoops! Your session has expired." error page will be shown up again.

Then, under the same windows, if I reload the page or manually enter order_status page URL directly (/index.php?main_page=order_status). Then enter a valid order number and email, click "Continue", you will see the order details. Then if you click Go Back button on your browser, there is a chance that it will show "Confirm Form Resubmission" error. Error code is ERR_CACHE_MISS. If error message is not shown up, click Go Forward button on the browser and you will see the error.

The bottom line is, it seems to me that for order_status function needs to use Cookies or session based. If it is the customer's first time to visit this order_status page (like using a new computer), it will show expired session error. Also it is not advised to use Go Back, Go Forward buttons from the browser during this page, because sometimes it will show ERR_CACHE_MISS error.

I've tried to reproduce on my demo site, but I'm not seeing the issue.

Hi @lat9, thanks for your response. I suspected there is something wrong with my www & https redirect in .htaccess file, so sometimes it will cause expired session issue. I tried a different snippet code in .htaccess now and it resolved this issue.

Thanks for your help again.

One more update. Unfortunately, "Whoops! Your session has expired." issue on order_status page on my site is still there. If I opened an Incognito windows or clean my browsers' cookies, and if I directly visit the order_status page, after I submit the form, I will see the expired session note there. But if I visited any links on my site at first then visit order_status page, it will function properly.

The updated htaccess file seems to fix my Go Back & Go Forward error then.

I tried an OPC demo site and that site worked fine. So it is something wrong on my site then. Well well, another headache on my site then...

2nd update. Hi @lat9, for your demo site, can you please help me to check if your admin/configuration/sessions/force cookie use is set to true or false?

My site is set to true. After I changed it to false, my order_status page works properly. If your site is set to false, you can set it to true and see if you can reproduce my issue.

I tried to search force cookie use in the forum and I could only find some very old posts. So in zc 1.57d, is it recommended to set it as true or false?
