hi... i m working on a management software using html,php,mysql.in my main page there are two frames,one is header and other is main frame.in main frame there is a login form. when i am submitting the form ,action attribute in the form tag calls the page in the main frame itself without changing the header frame. I want to bring the page mentioned in the action attribute in the browser itself without the header and main frame. I want that when i ckick the submit button of the login form,header and mainframe vanish out and new page comes without frames. thank you...
