One-Page Checkout [Support Thread]

dbltoe:

Yep, if the Admin >> Configuration >> Regulations are set to true, the system will not continue and throw the error.

Knowing that you get the same coupon result either way, can help with the troubleshooting.

I removed the the regulations, entered the coupon code, clicked APPLY and no coupon confirmation message either, so I'm guessing T&C box has no effect on this. I do need to have the regulations set to true though. I'll keep on working on the suggestions and see what I get.

Re-installed the plugin as it comes out of the box (well folder) before trying the suggestions and still the "Congratulations you have redeemed the Discount Coupon" won't display. :dontgetit

@lat9 I'm guessing this is what you where telling me to look for. I have no idea how to read that though :blush:

You got it, @mvstudio! That coupon-related message is 'targeted' (via that **class **parameter) to be displayed for a **checkout **group (which isn't one of the groups looked at by OPC). The base checkout_one-page template (tpl_checkout_one_default.php) will display the checkout_payment, checkout_shipping and redemptions groups by default.

If you make a template-override copy of that module, changing this section:

$messages_to_check = array('checkout_shipping', 'checkout_payment', 'redemptions');
foreach ($messages_to_check as $page_check) {
    if ($messageStack->size ($page_check) > 0) {
        echo $messageStack->output ($page_check);
    }
}

to read

$messages_to_check = array('checkout_shipping', 'checkout_payment', 'redemptions'[B], 'checkout'[/B]);
foreach ($messages_to_check as $page_check) {
    if ($messageStack->size ($page_check) > 0) {
        echo $messageStack->output ($page_check);
    }
}

... I believe that you'll find that coupon/reward-points message now displays.

FWIW, I've created a GitHub issue for OPC and will add that 'class' to its default display for the next release.

You're AWESOME!!!!! Thank you!!!
It does work beautifully for the coupons, but not for the reward points. Actually no message is generated at all for reward points not even on the regular ZC checkout.

But I can work with this. Since I have prevented coupons and reward points from being used together, I can reword the message for customers to remove the coupon if they want to use their rewards and viceversa.

Thank you so, so much!!! :hug:

No problems, @mvstudio; the resolution of your issue hinged on providing that screenshot!

I really really want to use OPC on my site, but having an issue with the square payment module and free shipping only. I looked through this thread and saw where someone else had a similar problem, but doesnt match mine... so here I go:
Dev site using:
PHP 7.1
Zen 1.5.6c (includes square code)
Mods so far are:
Slider on main page
Colorbox
Testimonials Mgr
News Mgr

Issue: Square shows up, but I get no input boxes
Hoping someone can help me figure out what is going on?

What template are you using, @stellarweb?

Hi Cindy - I just have it set on the generic responsive classic template. I switched to the classic green template and it is the same way - no input boxes.

What template are you using, @stellarweb?

Do the input boxes show if you disable OPC and checkout using the "traditional" method?

Yes, authorize.net shows up fine, I checked that first thing. I have also tried different versions of php and that didn't help either. I wonder if there is a javascript conflict with some of the mods I have installed? Do you think it will help if I try disabling some of the mod js and see if that changes anything?

I was asking whether Square shows up OK in the 3-page checkout.

Saying that, have you copied /includes/modules/pages/checkout_payment/jscript_square.php to /includes/modules/pages/checkout_one?

Sorry for the misunderstanding Cindy! BUT... the good news is that copying the jscript_square.php file over did the trick so I am all good!!! :clap:

Thanks so much for your help!!!

No problems, Judy; I'm happy to have helped. Note that you'll need to do the same copy-over with jscript_payeezy.php if you're planning on using that payment method.

I installed a one-page payment function and encountered a problem. I used PayPal to pay. After clicking submit, I didn't jump to the PayPal page. Instead, I went back to the default payment step and prompted the red word.

You have changed the items in your cart since shipping was last calculated, and costs may have changed. Please verify/re-select your shipping method.

I need to check which file has a problem with the code?

You haven't given me much information with which to diagnose your issue.

What version of Zen Cart, version of OPC is being used?

What template is being used?

What shipping methods were offered?

Which type of PayPal (PayPal Payments Standard, PayPal Express Checkout or PayPal Payments Pro)?

What other plugins are installed on the store?

Followup to my previous post here...

Report All Errors revealed nothing, there was no mention of checkout pages at all. OPC debug logs show nothing relevant, everything looks just the same as all other orders.

I now think this is related to the modifications I had added to the checkout process. I tried removing it and everything worked fine for a week. Then I restored the modifications and problems are back.
Several orders have gone through without any Shipping Address.

Did I make any mistakes with the custom-added session variable? Here's what I've done:
tpl_modules_opc_payment_choices.php - line 23 (right after <legend>):

$po_val = isset($_SESSION['po_number']) ? $_SESSION['po_number'] : '';

if($check_flag_group) {
?>
<!--bof comments block -->
    <div id="checkoutPurchaseOrder">
      <fieldset class="shipping" id="purchaseOrder"><legend><?php echo MODULE_PAYMENT_PURCHASEORDER_TEXT_PURCHASEORDER_NUMBER; ?></legend><?php echo zen_draw_input_field('po_number', $po_val, 'id="purchaseorders-po-number"' . $onFocus . ' autocomplete="off"'); ?></fieldset>
    </div>
<!--eof comments block -->
<?php } ?>

then, includes/modules/pages/checkout_one_confirmation/header.php - line 167 (right after $comments = $_SESSION['comments'];)

unset($_SESSION['po_number']);
if(zen_not_null($_POST['po_number'])) {
    $_SESSION['po_number'] = zen_clean_html($_POST['po_number']);
    $po_number = $_SESSION['po_number'];
}

and finally includes/classes/observers/class.checkout_one_observer.php on line 573 (right after unset for ceon manual card):

if (isset($session_data['po_number'])) {
            unset($session_data['po_number']);
        }

What am I missing? If I remove this code, everything works just fine. If this code is there, SOME orders come through without Shipping Address (database fields are left empty). :dontgetit :frusty:

Thanks!

@balihr, you've done all the right things from an OPC perspective (although I don't believe that you need that alteration to the OPC observer).

Your template change adds the data-gathering for that PO number and the change you made to the confirmation page's header records that value in the session prior to the session-hash value being created. That's why you don't need that OPC observer change as those 'unsets' deal with order-totals and payment- or shipping-modules that modify their session values during order creation.

What additional processing is being performed if a PO number is supplied for the order?

There is a step I think can be optimized, but I don't know how to modify it.

When the customer is not logged in, click checkout on the shopping cart page, and I want to jump directly to the registration page.
I am using the 1.55F version of zencart
One-Page Checkout version 2.1.2
I don't want customers to choose to log in or register when they check out.
Because I found that many customers shut down my website on this page.
They should prefer to see the registration information as they are new customers.

How can I modify the code to implement this idea?

It sounds like you should contact a developer ... see the Zen Cart Help Wanted area.
