Disable refresh

I have a page that uses php and mysql to submit information. Now once the information is submitted I do not want the user to click refresh. The reason why, is it will submit the information again and again. Is there a way to do this?

I would actually redirect them after their first submit. That is, after they submit their details, redirect them to a home page or a page that displays a successfully submitted message. If you stay on the same page there is no way to stop the user from submitting their details 100 times.

is that the only way? is there a programming language that could help me achieve this?

It's call AJAX, web 2. It uses Javascript and XML synchronously.

If you stopped the user from refreshing their page, that would be considered controlling the other persons browser and be named a "virus" by many. So, trust me don't use any control over your user, simply set a Session when they click the button, and then on the page you don't want them to submit again, check to see if that session is valid, and if it is just redirect them back to the page that you want them to goto.
