One-Page Checkout [Support Thread]

[lat9]

Cindy - My site runs on PHP 7.4, but I switched over to PHP 8.1 to test it out and iron out the bugs.

Can you help me resolve this error: --> PHP Warning: Attempt to read property "delivery" on null in includes/classes/OnePageCheckout.php on line 225.

I am running OPC 2.4.6.

I assume the error is a configuration thing on my end, since OPC 2.4.6. came out long after PHP 8.1 was in use.

The code snippet from that version is basically this:

global $order, $db;
$order_country = -1;
$order_country = $order->delivery['country_id'];

That class has change significantly between v2.4.6 and v2.5.1 (the current release). Try changing line 225 to read

$order_country = $order->delivery['country_id'] ?? false;

$order_country = $order->delivery['country_id'] ?? false; 

I was just coming here to update this! That worked. I had actually changed it to:

$order_country = $order->delivery['country_id'] ?? null; 

But it does the same thing. :)

After digging through the install process, I believe that under the following circumstances, OPC appears to be drop in.

ZC 2.0
IH
Clone a Template
Bootstrap (and I am using a clone of Bootstrap)
BS4 Slider

I did not see any files that needed to be merged but I wanted a sanity check :O

Right, the Bootstrap template already has the CSS needed for OPC interoperation. The only possible change needed are the overrides needed for the order_status page, if that's in use.

Has the situation changed where OPC's YOUR_TEMPLATE information sidebox needed to be installed prior to that of bootstrap?

OPC's readme says:

1. /includes/modules/sideboxes/YOUR_TEMPLATE/information.php (Added in v2.1.3); Note: If you are using the Bootstrap 4 Template, v3.4.0 or later, these changes are already incorporated!

Was asking as the two core file changes and the not-needed YOUR_TEMPLATE files when used with bootstrap could create problems if the user does a drop in only. See B under installation in the docs.

lat9 does the best docs. RTFM. Read the full manual.
