1.3.6 Fatal Error at checkout after upgrade - help please

After logging in and going to checkout or just going to check while being logged in, I'm getting this fatal error

Fatal error: Call to undefined function: zen_get_customer_validate_session() in /Volumes/Files/MCzenstore/includes/modules/pages/checkout_shipping/header_php.php on line 27

I've search and replaced to try to fix this and continue, but I can't find the error.

Any help would be appreciated

Have you replaced the offending file completely from a clean download?

yes I have replaced that one and replaced all the other checkout folders around it too

Kim,

I've also un-installed and re-installed all the shipping, payment and order total modules.

Is this a different server than you have used before? What is the OS? php version? MYSQL version?

This new folder was a carbon copy of the 1.3.5 (that was working) that was updated then renamed to take the place of the original.
The database was also upgraded successfully.

I'm at a loss to locate what's gone wrong.

thanks,
Jeff

For a test,
I took my entire 1.3.5 pages folder from my older folder and placed it into the new 1.3.6. folder and everything continued into checkout.

They I went back and tried to insert a stock 1.3.6 pages folder into the new site and it DIDN'T work. Same problem.
Any ideas on this?

thanks.
Jeff

the /modules/pages/checkout_*/header_php.php files had the new function-call added to them
the /includes/functions/functions_customers.php file had the new function defined in it.

If you failed to upgrade these files properly and in sync with each other, you will get errors.

Why is it always the little things that I seem to miss..?
I didn't replace the one file 'functions_customers.php' :(
(and I was so careful too!)

I'm so sorry to have bothered you on the petty things, but as usual, someone from you team came through to help those in need.

thanks for you help once again,

Glad you got it sorted out !

Without you and Ajeh this week, I'd be up the creek without a paddle.

This is only the first website in Zen-Cart. I have 2 more to create in the coming months. But now, I actually have to catch up on projects to bring 'in' the money. LOL

thanks again,
Jeff

I had the same problem, I did a forum search, found this thread, did what the zen-master said and my problem is fixed. You guys are truely great people, the fact that you make it free and offer this kind of help...amazing! When my store opens the first sale goes to buying you guys a cup of joe! Thanks zen

Thanks for the update that this was able to help you ... :smile:

We look forward to sharing a cuppa with you ... :cool:

I have fixed the problem adding to /includes/functions/functions_customers.php the next code:

-------------- cut ------------
// validate customer matches session
function zen_get_customer_validate_session($customer_id) {
global $db, $messageStack;
$zc_check_customer = $db->Execute("SELECT customers_id from " . TABLE_CUSTOMERS . " WHERE customers_id=" . (int)$customer_id);
if ($zc_check_customer->RecordCount() <= 0) {
$db->Execute("DELETE from " . TABLE_CUSTOMERS_BASKET . " WHERE customers_id= " . $customer_id);
$db->Execute("DELETE from " . TABLE_CUSTOMERS_BASKET_ATTRIBUTES . " WHERE customers_id= " . $customer_id);
unset($_SESSION['customer_id']);
$messageStack->add_session('header', ERROR_CUSTOMERS_ID_INVALID, 'error');
return false;
}
return true;
}
----------- cut -------------

The code is from the same file under 1.3.6 version. I think I have a good 1.3.2 mixed versions with newest 1.3.6 and 1.3.7 hehehehehe
