html post form action not specifically spell out php file?

Question

I have a post html form, and the action is index.php, which is the websites main page. I never actually have index.php in the address bar, since links to "/" go to it, and even if I did, it would be website.com/home(/), since I use rewrite rules. So basically, the user should never see index.php. However, the form submit doesn't work if the action isn't spefically index.php, "/" doesn't work, even though that resolves to index.php. Any ideas on how to get around this?

Answer 1

Don't specify the action. If the post is to the page they're on, the default action of the form is to post to that.
