As a last resort, I may have to do that, but that is by no means the preferred method. I want to keep database access to a minimum.
I thought by this time this problem would have had a standard solution. It would be nice if PHP had a function like refreshed() so one could do ... if (!refreshed()) { ... } ..., but I guess not.
PHP is a server-side programming language, the problem you are facing is a client-side problem. PHP thus would not be able to do browser refreshes! sorry! Unless of course you have a PHP enabled browser :-)
Your browser caches the information sent from the form and so long as the page is not reloaded..., the variables are still set and submition of data may continue indefinately.
Two options,
You may use the php header() funtion for redirection,
or
Resort to a client-side reload using a scripting language like javascript..., "document.location.href='....';
Assey.
Thanks for your input.

if(!$query_data) { do form }
else echo "information already exists in database";

Hello,
Scenario: 1) User is presented a blank form. 2) User fills in form. 3) User submits form. 4) Record is added to database. 5) Back to 1). All is fine to here. 6) User clicks refresh. 7) Another record is added, same data except auto-increment field. How do I prevent these last two steps, or at least prevent a record from being added when refresh is clicked?

Robert
