Hello,
My problem is this: I have a form which, upon submission, sends the user to a different page where he is sent an email message (using php). Now, if afterwards the user clicks the back button and then clicks submit on the form again he again receives the same email message. This is what I would like to avoid. My idea was to disable the submit button upon submission but once the user is forwarded to a different page and then comes back to the original form page, the submit button is enabled again. Is there a way to disable the submit button permanently after submission so the form can be submitted only once? Does anyone have a better solution?
Thanks in advance,
Aviv.
