One-Page Checkout [Support Thread]

archelaus:

OPC 2.0.5 and ZC 1.5.6a. I hate to waste people's time with something I should be able to figure out by myself, but I'm stumped. In guest checkout, the customer's billing address is pre-filling with the state/province listed for the store in Configuration>My Store and the zip code listed for the store in Configuration>Shipping/Packaging. I'm okay with it defaulting to USA, but I'd like state and zip code to be blank. I'm not seeing anything in Configuration>One-Page Checkout Settings, and the code in tpl_modules_opc_address_block.php is over my head. Thanks in advance!
That pre-filling of country/state/postcode was introduced in *OPC *2.0.1 to address the issue where some shipping modules (like USPS) don't send back quotes and, to my remembrance, also throw debug-logs if those fields aren't present in the 'order-object' when the shipping-modules are loaded. See this (https://github.com/lat9/one_page_checkout/issues/133) issue for additional information.

If it's important for you to not pre-fill those fields, you could make store-specific changes to the OnePageCheckout.php class-file, backing out the changes provided in the issue referenced above. Just remember, if you choose to, that you'll need to merge those changes into that class-file whenever you update your version of OPC.

That did the trick! Many thanks. I'm not using any of those shipping modules, and I have relatively few customers in DC (population 700,000), and almost none in my actual zip code, so I really did want to get rid of the pre-fills.

I need help, i am getting "Your order's details have changed. Please review the current values and re-submit." error message.
I am using zencart 1.5.5e . Can some one help me?

Sure, but I'll need a little more information:

What version of One-Page Checkout?
What template are you using?
What payment-module was chosen?
What shipping-module was chosen?
What order-total modules are applied to the order (before you click the Submit button)?
Was the order being placed for a customer with an account or was this using the Guest Checkout?

Sure, but I'll need a little more information:

1.What version of One-Page Checkout?
2.What template are you using?
3.What payment-module was chosen?

0.I Changed zencart version to 1.5.6
1.one_page_checkout-2.0.5
2.Template: yourstore
3.Check/Money Order I removed from Guest Disallowed Payment Methods tab for testing purpose.
4.Default (Flat Rate Best Way, Flat Rate Best Way, Store Pickup Walk In.
5.Default
6. I tryed both ways as a guest and as a customer.

I have to figure it out. Thanks for your reply lat9.

When placing an order, I get this error:

If it matters....site was upgraded from 1.5.4. OPC was not installed previously. Using a custom template.

As I keep playing with this excellent plugin, I've come up with a suggestion for a very minor improvement:

If you change line 25 of tpl_modules_opc_address _block.php from

if (count($address_selections) != 0) {

to

if (count($address_selections) > 2) {

customers will see the dropdown list of previously defined addresses only when there's actually more than one address for them to choose from. (It's > 2 rather than > 1 because the "Select from saved addresses" line counts as an address.)

Per the plugin's readme, the YourStore template is known to be incompatible with One-Page Checkout.

Good catch! I've opened an issue on OPC's GitHub repository to track the change (https://github.com/lat9/one_page_checkout/issues/171).

I'll note, though, that dropdown list should be shown if the customer has more than 1 (not 2) addresses previously recorded.

See this (https://github.com/lat9/one_page_checkout/issues/165) GitHub issue; let me know if that corrects the issue when a store doesn't have ot_gv enabled.

There was a change made for zc156 such that an empty array (instead of false) is being returned in that case, that's what the change for that issue addresses.

Thanks. I've applied the change and will check back to see if the error goes away.

Hmm. When I did it, I had to set it to 2 for it to work. I concluded that it was counting "Select from saved addresses" as an address.

Arggh, you're quite right; let me get that corrected on GitHub.

Yes I know that, but still I think I can make it work. Yourstore support offered me to install this plugin for alot of money. This template use unique method to show header and I think this is the main think why plugin isn't working properly. With your knowledge I think it's possible to merge those two files. But maybe you know better where is the problem. Thanks

The **YourStore **template (and its ThemeForest siblings) gave me quite the headache when I investigated the interoperability a couple of years ago. It's not something that I'm willing to offer as a free service.

I am willing to pay some money for your help. Can you tell me how much this can cost for me?

:beta:I've completed the changes for One-Page Checkout, v2.1.0, and have packaged up v2.1.0-beta5 for download from the plugin's GitHub repository. **Do not deploy this on a live site!

**I'd appreciate any/all beta-testing that the community can provide, especially with respect to the installation/upgrade documentation ... which has changed significantly. Please report any issues found (or suggestions for improvement) as GitHub issues on that repository.

PHP 7.2
ZC 156a
OPC v2.1.0-beta5

I've been testing with this build but I'm only using "PO Number Payment and Flat Rate Shipping" so I'm not covering the corner cases.
The documentation seems to be OK if you read it carefully.

The only issue I have is:
The "Shipping Address" drop list on the checkout page is listing the addresses in the order I entered them NOT in any alphabetical order.

Googled and checked the forums but can't come up with a solution.

Any clues on how to make that sort on Company name would be appreciated.

Thanks

FWIW, I'm up to OPC v2.1.0-beta8.

You'll need to edit (and make a copy of) /includes/classes/OnePageCheckout.php to edit its formatAddressBookDropdown method:

    
    public function formatAddressBookDropdown()
    {
        $select_array = array();
        if (isset($_SESSION['customer_id']) && !$this->isGuestCheckout() && !$this->customerAccountNeedsPrimaryAddress()) {
            // -----
            // Build up address list input to create a customer-specific selection list of 
            // pre-existing addresses from which to choose.
            //
            $addresses = $GLOBALS['db']->Execute(
                "SELECT address_book_id 
                   FROM " . TABLE_ADDRESS_BOOK . " 
                  WHERE customers_id = " . (int)$_SESSION['customer_id'] . "
               ORDER BY address_book_id"
            );
            if (!$addresses->EOF) {
                $select_array[] = array(
                    'id' => 0,
                    'text' => TEXT_SELECT_FROM_SAVED_ADDRESSES
                );
            }
            while (!$addresses->EOF) {
                $select_array[] = array( 
                    'id' => $addresses->fields['address_book_id'],
                    'text' => str_replace("\n", ', ', zen_address_label($_SESSION['customer_id'], $addresses->fields['address_book_id']))
                );
                $addresses->MoveNext();
            }
        }
        return $select_array;
    }

Note, though, that this class is very 'volatile' as it's the heart of OPC's processing.
