include or require or what?

I am working on a form that needs to run INSERTS into a table, but also has other connections and functions going on, so $php_self isn't really an option (I'm a newbie, and switch still scares me)... Can I effectively use an include/require(insert.php) on the main of the form, have the form action be insert.php but stay with the form, and if so, HOW? __________________________________________________ Do You Yahoo!?
