Is there a "Login" function similar to the "save"?

[Noel 4 DMB]

I am currently saving registrations externally from vbulletin's register.php using some hacks i found on this site. However, after i save them, they have to login manually. Is there a way i can take the same registration info and then log them in with php before the page reloads? Please help!

Maybe take a look at the following chunk of code in the login.php file and incorporate that into your external registration process:

if ($_POST['do'] == 'login')
{
	// blah blah
}
