One-Page Checkout [Support Thread]

[njcyx]

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'] ?? '';
