One-Page Checkout [Support Thread]

[Jeff_Mash]

I'll come up with a set of instructions that you (and others!) can use to determine what's causing that 'kick-back' from the confirmation page back to the data-collecting one.

I think that would be an EXCELLENT addition to your already excellent module! Can't wait to see it and try it out.

Jeff, after actually reading your post (I was seeing that the Reward Points' contribution to the order was a negative value), I'll need to review whether OPC 'cares' that the order's value is negative.

Okay, I will wait to hear back from you. I just assumed it was your module spitting it back because it isn't liking "something" from the values being submitted to it. I did confirm that the issue (regardless of which module is causing it) is definitely with the negative value. If I submit the order without a negative value, it goes through the OPC confirmation just fine.

Granted, the situation I describe isn't very common (but does happen from time to time). Since reward points are always in whole round numbers, they usually will create some kind of negative order_total when applied fully to an order. And normal non-OPC checkout handles it fine........meaning the order gets submitted with a negative number. If I can help test anything out for you, please let me know.

ZC v1.57
PHP v7.2.10
OPC v2.3.4
CEON
DPU
SBA
Quantity Discounts
CSS_JS Loader
IH5
Colorbox
Structured Data

Upgraded an existing ZC v1.56c site to ZC v1.57 and I'm have difficulty debugging this issue:

Checking out as a guest I'm successfully directed to the OPC checkout_one page and all's well. But checking out as a logged in customer I'm taken to Step 1 (checkout_shipping) page - it's as if OPC is not kicking in (unlike in ZC v1.56c w/OPC v2.3.4). There are no errors in the browser console (I'm not loading OPC minified script files) or logs directory.

Any ideas where I would start looking?

Simon, have you applied all the zc157 bugfixes? Does OPC generate a customer-specific log for the situation?

Yes it just occurred to me to check the ZC v157 bug fixes, I thought I could get away with waiting until ZC v1.57a was released. I'll apply those, try again and then post a customer log if neccessary - thank you. In the meantime the customer log generated in this instance is:

The bug-fix that most likely is "getting you" is in post#8 of that bugfix thread (https://www.zen-cart.com/showthread....v1-5-7-series).

[simon1066]

This was the bugfix that needed to be applied - Re: 157: plugins watching shared notifiers may not all trigger properly , I should have paid more attention to that thread.

Hello,
I am finally finding time to work further on trying to add support for Japanese (some issues with zones, as well as adding language and hiragana fields) to OPC.
I have had to disable OPC because while it worked beautifully for guest checkout and registrations, it gave an error when trying to add addresses, since my shop's user creation and address book registration/changing code has been modified to support the needs of users here in Japan (selecting a language for the address, so that users can register an address in either English or Japanese, and then fields for hiragana name/surname as appropriate, plus multilanguage zone and country support).

I am working now using the code of OPC 2.3.4.

I suspect most of my work will be limited to editing files in includes/modules/pages/checkout_one/, with no changes needed in modules/pages/create_account/ unless I want to change the default population of an account.

I understand I will need to change the function "saveAddressValues" in the file jquery.checkout_one.js. This seems fairly simple.

However, in the file jquery.checkout_one_addr.js there is mention of an array "z2c" in function "updateCountryZone", but I cannot find this anywhere.
Apparently it is supposed to be supplied by jscript_main.php, but there is no mention of it there. I definitely need to edit the creation of this array. Can anyone point out where I may find it?
