Sure. Usually you have one page or controller that deals with login.
So lets say you are on "About us" page. The login form on that page will always post to login page url
Code:
<form action=" mycontroller/login " >
...
</form>
When user enters login details, it is always sent to single controller, if login details were wrong, the controller shows new form with error message on the on it's own.
To make things more user friendly / more complicated for you, you can, after successful login redirect users back to the original page with either using <b>$_SERVER</b> referrer or adding hidden input field with URL to a the form.
