Form Help

[kevincro]

I've coded a form in HTML and I use PHP to process the info.  What I'd like to know is how I can make to where the form can only be submitted once.  I have a problem at the moment with the form being submitted by users hitting the back button and the refresh button.

Thanks

use header file to remove the post data

 

header ()

[kevincro]

I'm not sure how to do that

[teng84]

after you process your data with that (post)  add the header

 

eg...

 

sql(insert....)

blah blah

header('location : yourpagehere.php');

exit();
