submit form witout clilck submit button

Hi all I have to submit username, domain name and password values to the cgi file, It starts from the login page and submit values to a php page to tie up username and domain name value together before submit it to the cgi file as two values ( "username+domainname" , "password") . The thing is that at php file, how do I submit those values without user click on the submit button, say make the form submit right away as soon as the page is read?
