Zen Cart version?

Sorry,

This is just a partial (had to cut it to fit) but, today, we have started getting the line 567 added to the mix.

@dbltoe, what happens if you change line 567 of /includes/classes/OnePageCheckout.php from

        $this->debugMessage('startGuestOnePageCheckout, exit: sendto: ' . ((isset($_SESSION['sendto'])) ? $_SESSION['sendto'] : 'not set') . ', billto: ' . ((isset($_SESSION['billto'])) ? $_SESSION['billto'] : 'not set') . var_export($this, true));

to

        $this->debugMessage('startGuestOnePageCheckout, exit: sendto: ' . ((isset($_SESSION['sendto'])) ? $_SESSION['sendto'] : 'not set') . ', billto: ' . ((isset($_SESSION['billto'])) ? $_SESSION['billto'] : 'not set') . json_encode($this));

If that suppresses the error, would you turn on the OPC debug and send a copy of the generated log to my private email address? I have no idea where that circular reference is coming from.

[dbltoe]

commented out line 567 and added your code to 569. Got

[06-May-2022 20:57:29 UTC] PHP Parse error: syntax error, unexpected ')' in /includes/classes/OnePageCheckout.php on line 569

[06-May-2022 20:57:29 UTC] Request URI: /index.php?main_page=index&Path=3, IP address: 157.55.39.46
--> PHP Parse error: syntax error, unexpected ')' in /includes/classes/OnePageCheckout.php on line 569.

so I put 567 back.

Hi, me again!

I think that in checkout_one_confirmation/header_php.php there is a problem with the message stack.

Here's the code that handles the "translation" of messages to the correct class of message:

if ($error || $messageStack->size('checkout_payment') > 0 || !$order_confirmed) {
    // -----
    // Need to "redirect" any messages to 'checkout' (issued by ot_coupon and possibly others) so they display properly
    // on the checkout_one page.
    //
    if ($messageStack->size('checkout') > 0) {
        foreach ($messageStack->messages as $i => $current_message) {
            if ($current_message['class'] == 'checkout') {
                $messageStack->messages[$i]['class'] = 'checkout_payment';
            }
        }
    }

    $checkout_one->debug_message("Something causing redirection back to checkout_one, error ($error), order_confirmed ($order_confirmed)" . var_export($messageStack->messages, true) . var_export($ot_total, true));
    zen_redirect(zen_href_link(FILENAME_CHECKOUT_ONE, '', 'SSL'));
}

The problem is that the method $messageStack->size includes a reset of the variable $_SESSION['messageToStack'] which means that one loses all the add_session messages.

I think you need to do something like:

$temp['checkout_payment'] = 0;
$temp['checkout'] = 0;
if (count($messageStack->messages)) {
    foreach ($messageStack->messages as $m) {
        switch ($m['class']) {
            case 'checkout_payment':
                $temp['checkout_payment']++;
                break;
            case 'checkout':
                $temp['checkout']++;
                break;
            default:
                break;
        }
    }

}

if ($error || $temp['checkout_payment'] > 0 || !$order_confirmed) {
    // -----
    // Need to "redirect" any messages to 'checkout' (issued by ot_coupon and possibly others) so they display properly
    // on the checkout_one page.
    //
    if ($temp['checkout'] > 0) {
        foreach ($messageStack->messages as $i => $current_message) {
            if ($current_message['class'] == 'checkout') {
                $messageStack->messages[$i]['class'] = 'checkout_payment';
            }
        }
    }
    $checkout_one->debug_message("Something causing redirection back to checkout_one, error ($error), order_confirmed ($order_confirmed)" . var_export($messageStack->messages, true) . var_export($ot_total, true));
    zen_redirect(zen_href_link(FILENAME_CHECKOUT_ONE, '', 'SSL'));
}

Hi Lat9, I just installed this plug-in (v2.4) on my testing site 1.5.7d, php 7.4. Under admin--One-Page Checkout Settings, I have enabled this plug-in. However, this plug-in does not show up like the demo website. The Guest checkout section did not show up if I clicked "Go to checkout" button in the shopping cart. When I checked the log file, I received the exact same warning:

--> PHP Warning: var_export does not handle circular references in /includes/classes/OnePageCheckout.php on line 567. 

I commented out this line and put your new code there. No warning file is generated but this plug-in still doesn't show up.

[njcyx]

Ok. I found out why my plug-in didn't show up. After the plug-in is installed, two settings need to be changed manually:

Enable One-Page Checkout?
False => True

Enable Guest Checkout?
False => True

Now it works, other than the warning log generated:

--> PHP Warning: var_export does not handle circular references in /includes/classes/OnePageCheckout.php on line 744.

When debug is ON, I received the following warning:

--> PHP Warning: var_export does not handle circular references in /includes/classes/observers/class.checkout_one_observer.php on line 690.

Line 567 warning is gone, by changing the code provided by Lat9 in the previous posts.

See https://github.com/lat9/one_page_checkout/issues/328 for the resolution to this issue.
