I want to put some code at the top of my pages which will prompt the
user for a name & password if the session variable IDUser is not set.
How do I get the browser to display the login / password dialog and how
do I access the data the user entered.
Can I put the code that gets the login / password in a page of it's own
and have the browser call that page when the IDUser isn't set, and if
so how do I do it eg.
<?
session_start();
If($_SESSION['IDUser']==''){
//how do I tell it to do the authentication page
}else{
//rest of my code
} ?>
Once the user entered a login / password and I set the IDUser on the
authentication page, how do I tell it to resume loading the original
page (the one that had the above mentioned code on it)?
