One-Page Checkout [Support Thread]

[gernot]

@lat9
I am looking into your suggestion of class inheritance. First time to do, and I am confused as to where the new and old class are supposed to meet logically.

Firstly, I am not sure whether class override means overriding the whole class, or just a subset of its functions. I assume the latter for now in this example.

Let's say I create new file OnePageCheckoutJP.php and in it have a new class definition to extend your class:

OnePageCheckoutJP extends OnePageChekout

Then I put only the changed functions, with the same names as in the original OnePageCheckout class, into the new file.

Then in class autoloader file config.checkout_one.php I would (well, it would be a new file, but just to illustrate the point) add new definitions for loading (CP-1) and instantiation (CP-74):

autoLoadConfig[0][] = array(
    'autoType' => 'class',
    'loadFile' => 'OnePageCheckout.php'
);
// new CP-1 loading
autoLoadConfig[1][] = array(
    'autoType' => 'class',
    'loadFile' => 'OnePageCheckoutJP.php'
);
// new CP-74 instantiation
$autoLoadConfig[74][] = array(
    'autoType' => 'classInstantiate',
    'className' => 'OnePageCheckoutJP',
    'objectName' => 'opc',
    'checkInstantiated' => true,
    'classSession' => true
);

$autoLoadConfig[75][] = array(
    'autoType' => 'classInstantiate',
    'className' => 'OnePageCheckout',
    'objectName' => 'opc',
    'checkInstantiated' => true,
    'classSession' => true
);

In this class override, does the "objectName" remain "opc"? I am confused (easily I may add!).
You wrote "then the base OPC class will not be loaded", that seems to imply that actually I need to override the entire class rather than just certain functions within the class?

Any pointers much appreciated.

@gernot, you're on the right track!

First, in the new auto_loader, you'll instantiate your class-override as the 'opc' session value. Since that will occur at CP-74, the instantiation of the base OPC at CP-75 won't occur, since the auto-loader won't overwrite that class if it's already there.

For the class-inheritance, you're correct ... you'll only provide the methods in your class that are being overridden, with the same names and inputs as the 'base' OPC methods. You might take a peek at my Database I/O Manager as its /admin/includes/classes/dbio/DbIo*Handler.php classes use class-inheritance to provide handler-specific actions while using common/base functions within the DbIoHandler.php class.

On the download page I saw Stirpe mentioned at v1.0.7 and v1.0.8
Do I need to install the Stripe plugin as well?
Thank you.

Only if that's what you want to use for payments on your store. OPC doesn't include any additional payment modules in its zip-file.

Hi again Cindy - on both sites that have been upgraded I am now repeatedly getting an PayPal error code 10730 - after checking out going through guest checkout / PayPal and getting to PayPal and clicking pay now I get returned to the guest checkout page (all details still completed) with this error at top of the page;
"Error 10730 Shipping Address Postal Code Empty - The field Shipping Address Postal Code is required"

The postcode is completed in the billing address section - the shipping address is same as billing address box is checked (default I assume) - even when I uncheck that box the details shown for shipping are as per billing and includes the postcode.

I get this error code;

[11-Nov-2019 09:09:29 Australia/Sydney] PHP Parse error:  syntax error, unexpected ',' in /home/admin/public_html/includes/modules/payment/paypalwpp.php on line 2034

this is the line you modified - not sure if this is relevant but in the email received that line of code was represented as ;

$this->zcLog('ec_step2_finish - 2a*'*, *'*address-creation bypassed based on observer setting.');
      }

(possibly a character interpretation issue with the email program ??)

in the forum on the ZC site in the post above it is shown as;

 if ($bypass_address_creation) {
          $this->zcLog('ec_step2_finish - 2a', 'address-creation bypassed based on observer setting.');
      }

I initially used the code in the email but it caused a blank page after clicking checkout - I am now using the code from your post above - resulting in that error.

For the life of me I cannot figure why it worked first time as I indicated in my post but now wants to throw this error. I have cleared cache and restarted browser.

cheers,
Mike

Was there ever a fix for this? I have a client getting the 10730 error. It seems to be occurring only with guest checkout and when using a credit card to pay on PayPal.

Zen Cart 1.5.6
OPC 2.3.4

Jim, since you're using a 'base' zc156 (no alpha-suffix), did you follow the installation/update instructions for that version: https://github.com/lat9/one_page_che...-cart-156-156a

That identifies additions/changes needed for the older Zen Cart 'core' modules, especially the addition of a notification within the paypalwpp.php module to enable an observer (like OPC's) to instruct the processing to bypass the customer-record creation.

Sorry, typo. ZC is 1.5.6c

Try enabling the paypalwpp debug mode. For those PayPal paid orders during guest checkout, you should be seeing

ec_step2_finish - 2a', 'address-creation bypassed based on observer setting.

in the PayPal-generated logs.

Dang, I just cleared them thinking it would be in one-page logs. I'll watch for more and report back.

Actually, having both the PayPal and OPC logs will both help to "read the tea leaves"!
