I am having a few problems with people accidentally submitting the same form twice and duplicate eway payments being processed.
If you use gravity forms with confirmation text at the conclusion users can resubmit the confirmaton page through browser refresh and this results in a form resubmission and another payment.
People also can use the back button and press submit more than once to generate accidental form resubmissions.
This is discussed on a few recent gravity forms threads http://www.gravityhelp.com/forums/topic/submitting-same-form-multiple-times and http://www.gravityhelp.com/forums/topic/multiple-notifications-sent-when-refreshing-confirmation-page I saw a few other threads also.
I was wondering if there was anything that could be implemented within the eway plugin to stop accidental resubmissions of the same transaction.
I already hide the submit button after it is clicked but this isn't enough so if you have any ideas that would be great.
