I'm testing our ubercart module and I can't seem to get to the review page. Every time I hit the check out button and the button of the page I get this error "To protect our customers from identity theft, credit card details are erased when a browser refreshes on the checkout review page. Please enter your card details again and re-submit the form." I have tried everything. I have updated to the latest module. I have tried disabling almost everything. In my reports, I'm getting this error 3 times anytime someone tries to click the checkout button. (image of error attached) I have spent all day trying to figure this out with no luck. I have tried both Test Payment gateway and authorize.net. Nothing is working.

There's this block of code in the uc_credit module that is stopping me. If I comment it out, I get to the review page but none of credit card details are getting passed to the page. I believe the $_POST['sescrd'] is never getting populated, but I dont know where/how to fix it.

if (isset($_SESSION['cc_pay']) && !isset($_SESSION['sescrd']) && empty($_POST['sescrd'])) {
// Send them back to the checkout form to put in their details again.
drupal_set_message(t('To protect our customers from identity theft, credit card details are erased when a browser refreshes on the checkout review page. Please enter your card details again and re-submit the form.'), 'error');

$_SESSION['clear_cc'] = TRUE;
unset($_SESSION['cc_pay']);
drupal_goto('cart/checkout');
}

I found a way around this problem. I think the issue is with the encryption. In sites/all/modules/ubercart/payment/uc_credit you need to modify the encryption functions. At around line 534 you will find a line of code that reads:
$_SESSION['sescrd'] = $crypt->encrypt($key, serialize($order->payment_details));

Change this to:
$_SESSION['sescrd'] = base64_encode(serialize($order->payment_details));

(I know, its less secure, but it WORKS)

Then around line 1284 look for:
$cc_cache = unserialize($crypt->decrypt($key, $data));

Change this to:
$cc_cache = unserialize(base64_decode($data));

and it should work for you.

NOTE: These are not exact line numbers. I have debugging code commented out in my code, so you will have to look for the specific code that I indicated above.

Message me if you need any more help.

Same issue here.
bradjmsu's workaround did resolve the issue.
Is this also relevant to the other gateways (real cc gateways, not just test gateway)?
If so I hope this will this be submitted as a fix to the module in the next version.

Ehud Ashkenazi

Ehud,

I tested this with Authorize.net and I don't seem to be having any problems with it. I have seen some successful conversions so I assume there are no existing issues with the solution.

If it helps anyone, I had this problem and the issue turned out to be that the uc_encryption_class was borking on a hidden newline character at the end of the file uc_credit.key. Removing this resolved my issue. It would seem to me that a patch for the uc_encryption_class that ignores white space characters etc. would help.

Also, there's an error property as part of the uc_encryption_class (eg. $crypt->error) that you can investigate for clues as to why the encryption is failing. Note that error is a property, not a method as the documentation suggests.

i also had this problem, & i didn't want mess around with the modeule source code...i eventually found the found the culprit in the Payment Settings area

In the Credit Card Settings (Choose Payment Methods >> Payment Settings >> Credit Card Settings), and look to the Card Type Select Box Options -switch this field to PLAIN TEXT, and get rid of all the HTML tags, and save.

Problem solved!
