clearing post data

[lional]

I have a script, but if a user uses the back button I want the post data to be cleared.

Is there a way to do this?

 

Any help will be appreciated

You can do a trick if its not the browser's Back button. If you have Back button <input type="submit" name="Back" value="Back"/> then on click of this you can redirect the user to location with some parameter passed like http;//previouspage url?btn=back and on the previous page you can put up the logic that if $_GET['btn'] is back then unset($_POST).

 

But if its a browser's back button then I believe its going to be tuff. but you can follow below link for your help

Yes, once the user posts the form and the data gets entered do a header redirect to a "thank you" page. This will clear the post data, so if they push back it will not re-submit the data.
