One-Page Checkout [Support Thread]

zc 1.58a. php 8.1. opc 2.5.2.

I received the following warning.

Request URI: /ajax.php?act=ajaxOnePageCheckout&method=updateShippingSelection, IP address: xxxx, Language id 1
#0 /includes/classes/ajax/zcAjaxOnePageCheckout.php(115): zen_debug_error_handler()
#1 /includes/classes/ajax/zcAjaxOnePageCheckout.php(104): zcAjaxOnePageCheckout->formatOrderTotal()
#2 /ajax.php(85): zcAjaxOnePageCheckout->updateShippingSelection()
--> PHP Warning: Undefined array key "opc_saved_order_total" in /includes/classes/ajax/zcAjaxOnePageCheckout.php on line 115.

Line 115 is the following section:

    protected function formatOrderTotal()
    {
        return $_SESSION['opc_saved_order_total'];//line 115
    }

Does the following change work? $_SESSION['opc_saved_order_total'] should not be zero or null?

return $_SESSION['opc_saved_order_total'] ?? '';

Hmm, that shouldn't happen. Does the associated site, by any chance, have something like the "Remember Me" plugin installed?

Hi @lat9,

No plug-in, but I added a php file to extend the session/shopping cart expiry time. Not sure if it is related.

<?php define('SESSION_TIMEOUT_CATALOG', 7200);

This file is under /includes/extra_configures/my_ultra_long_session_timeout.php file

Looks like that could happen if an error occurred in either initializeResponseStatus or there was an issue with the shipping selection.

I'll be changing that method to read

    // -----
    // Called to format methods' return of the order's current total,
    // rounding to the number of decimal digits in the session's active
    // currency.
    //
    protected function formatOrderTotal()
    {
        global $currencies;

        return $_SESSION['opc_saved_order_total'] ?? $currencies->format(0);
    }

After upgrading to the new Square_webPay 1.2.1 I found a bug in (I think) OPC. While checking out and paying with Square_webPay, OR check/money order but NOT Paypal Restfull, If I change what's in the special Instructions or Comments field (or whatever 'TABLE_HEADING_COMMENTS' was defined to originally) I get the error "Your orders details have changed. Please review the current values and re-submit. I had had trouble with this previously with paypal, but not connected it to the comments field.
ZenCart - 1.5.8a
Bootstrap - 3.6.0
OPC - 2.5.1
Square_webPay (paid version) - 1.2.1
PayPal Checkout (RESTful) - 1.0.2

Hoping to upgrade OCP to 2.5.2 today, will post if it still happens in that version.

Hmm, I searched the keyword "SESSION_TIMEOUT_CATALOG" and I found my same post back in 2024...

The modules I installed now are: OPC, some shipping modules, local sales tax, sales report II, monthly sales and tax summary and google recapchar.

The log you posted indicates that the issue is that data types in the saved session's OPC variable aren't compatible with those now 'required' by the v2.6.0 update.

While I'll keep my eye out for other reports of this issue, I've got no "good" solution for you other than running the following SQL queries after you've made a full backup of your database:

TRUNCATE TABLE sessions;
TRUNCATE TABLE whos_online;

Hi @lat9, thanks. I just tried your suggestion in the testing server and it worked! After I cleaned both tables, The white screen tab can display as normal.

Regarding my database, I used zc database conversion tool (v2.0.1) to convert my database to utf8mb4_unicode_520_c from (I suspected) utf8, when I upgraded my site to zc210.
