I have a form on a page, which then submits itself to itself. Basically; the page acts as the processor and does what needs to be done. Problem is; once what is done is done, doesn't work up on the page UNTIL a refresh is made. Upon a refresh the data will be submitted again, how can I come by this and like automatically refresh it without re-sub?

Done

echo "<meta http-equiv='REFRESH' content='0;url=http://www.yoursite.com/'>";

Yes... Using META Tags is good. You can also display some message that the page will be redirected or the page will be refreshed in X seconds.

You can also use http redirect after processing form input to reload the page (which will also release post data from the form) if your processing is done before any other output is sent to the browser.
