1. Use $_SERVER['PHP_SELF'] as a form action.
The $_SERVER auto-global array holds various useful server- and request-specific info. The PHP_SELF element of $_SERVER holds the filename of the currently executing script (relative to your web site's document root directory). So, supplying $_SERVER['PHP_SELF'] as the action attribute of the form tag makes the form submit to the same page that displayed it.
