Login Forms, please help, how do i get a log in form on my website? Options

[what should i put here]

well i need to know how to put a login form on my site, i havent put it on the internet yet, but with my html coding its exact like some sites are.

i can click the submit button and it goes straight to the new page, but i want people to use the login part so they enter username/password etc. and then press button, so if they dont enter anything and press enter it wont go, but a popup box will say: please enter your username and password... please help me

To password-protect a site with a login form, you can let the server-side program check the submitted password. The file on the server containing passwords should not be viewable by users. See the FAQ for form basics.

If you instead of a form use HTTP authentication the browser will provide a login prompt. See also theFAQ.

This can be done with javascript, but the actual PW-protection should not rely on that. See http://htmlhelp.com/faq/html/forms.html#required-fields
