form submit

[eluser]wojtekk[/eluser]
i know how forms works and how to put data to database the problem is how to send them futher with post
i could use onclick sumbit button make AJAX call to submit.php (so it would be normal html post to action url and ajax would make input to database) or just use
GET:
in controller

Code:

header( 'Location: siteurl?datafromform');

and it works but i want send them with POST
