How could i prevent a user from hitting the refresh button in the browser?

If the user hit the refresh button, the data will then be posted to database as a new record with a new primary key which i have set it as an auto increment primary key. How can i avoid this from happening?

what is the difference between using (1)include "hello.php" and (2) header (Location:"hello.php");?

1.) No, you cannot stop them from refreshing. Just code better to prevent double entries.

2.) include loads the file into the current script, header("Location: xxx") will redirect you to that page.

As an extra from Prismatic, you can disable or remove the submit button [in a form] after its been clicked to prevent users clicking it more than once but for this you'd need to add a little javascript to hide it once pressed - surprised how many people keep clicking adding more data on a slow connection.
Not a pro just an enthusiast :)

if (empty($coffee)) {$coffee=new coffee();}

Please surround any code using the CODE tags - I rarely look at anything without them
