Opencart Version: 2.0.3.1
Theme: Custom

Hi guys,

We're currently encountering an issue whereby occasionally customers will mistakenly order the same thing twice. I believe this is happening where customers are impatient and click the checkout button more than once.

Can anyone advise if it's possible to set opencart to only take payment once during checkout?

We are using the Worldpay payment method, for reference.

Thanks in advance!

Check the develover's guide. You will have to add a beforeSubmit callback to disable/enable the submit button:

Thanks for your reply!

Are you able to expand on this at all in terms of how to add this? I can't seem to find this in the guide (we don't normally fiddle with the payment gateway files).

Find the callback section, there try to disable the "Order/Pay" button

Or, find a more up-to-date extension on the Marketplace.

The most generated errors being found on Opencart forum originates from contributed programming. The increased post counters are caused by redundancies of the same solutions that were already provided prior.

As far as I remember, OpenCart does disable the checkout button after it's clicked so it must be your WorldPay gateway that doesn't.

Contact the extension developer.

There is an example using beforeSubmit here.

You will have to update the worldpay.tpl file somewhat, as it seems to use an old version of the Worldpay JavaScript library. We found the even this and adding a second check in the controller did not stop all the duplicate payments. And there were a few other bugs.
