Schmidty,
Where are you updating the database? And where are you retrieving the
values?
PHP is server-side. ALL code is executed before the page is sent to the
browser. Interaction between PHP and the browser is one-way - the PHP
sends the page and terminates. There isn't any interaction between the
browser and the PHP code (other than to load a new page).
When they click on the submit button for the form, the browser requests
the page identified in your FORM statement. Since it is the same page,
all of the PHP code is executed again.
But you didn't show most of your code so there's no way to determine
what might be going on.
And no, you don't need AJAX or similar for this to work. Straight PHP
works great.
