Intermittent duplicate orders

[badarac]

I've been debugging intermittent duplicate orders on a 1.3.9h site. Looking at the logs it appears that the customer is hitting the confirm order button multiple times and it creates a new order each time. I found and applied changes from the forums related to using CSS buttons. This has not solved the problem. I turned on debug so I have log files but nothing is jumping out at me as the cause of the problem. Any suggestions on how to stop this or debug it?

I believe that this has been addressed in at least ZenCart v1.5.4 with ajax

<?php
  echo zen_draw_form('checkout_confirmation', $form_action_url, 'post', 'id="checkout_confirmation" onsubmit="submitonce();"');
?>

You are using about 5 year old code - time to upgrade

Thanks for that. That line of code is already there. I'm in the process of going through the upgrade but it's still going to take some time. This 1.3.9 install was heavily modified. Any other ideas?

I thought that the transition from $_GET to $_POST commands was part of the solution... Been a while since worried about that issue. Thought that was a revision into 1.5.x.

I do not see any implementation of "ajax" in a fresh copy of 1.3.9
That file is tpl_ajax_checkout_confirmation_default.php

Sorry, I misunderstood what you were trying to tell me. I focused on the "submitonce" which was in red as the solution. That of course was part of the line in 1.3.9.
