Re: Logout with auth_HTTP

Hm, I didn't see a repost.... I've not used HTTP_QuickForm, but I don't see why you couldn't. I use Smarty myself. As long as the form that's generated has the necessary named fields (see the Auth docs), it shouldn't matter how you generate it. And I realized AFTER I sent my message yesterday that I was talking about Auth, not Auth_HTTP. I'm not sure if there are any relevant differences between the two, having not used Auth_HTTP. :-) Good luck either way. Jonathan Loran wrote:

Thanks Larry, This is helpful. (And sorry for my latest repost. For some reason, I got a bounce message from the first one.) I have another question: In the function showLoginPage(), can I use a PEAR HTTP_quickfrom? That would be very nice to do. Cheers, Jon

I've found the Auth documentation to be somewhat poor in that respect as well. What I've done is create a separate authenticateUser.php file that I include at the top of each page I want restricted. It's based off of the documentation's examples but puts them together in a way that works, whereas the documentation is all piecemeal. Also, I found that the precise location of certain method calls is extremely important. Put the second start() call in the wrong place and you get the same symptoms you describe. An abridged but hopefully fully functional version of the file is included below. Feel free to use it verbatim or modify if you need. -------------------------------------- <?php require_once('Auth.php'); /** * Display the login page *

 * @author    Larry Garfield

*/ function showLoginPage() {

    // Various print statements, or template call, or some output.
    // This sends an ENTIRE valid page.

} // Set up a new Auth session, based on our installation configuration $params = array(

    "dsn" => 'yourstringhere',
    "table" => 'Users',
    "usernamecol" => 'username',
    "passwordcol" => 'passwdcrypt'

); $auth = new Auth("DB", $params, "showLoginPage"); $auth->setSessionName("MYAPP" . "_SESSION"); // Start the authentication process, meaning display the login page if necessary $auth->start(); // If told to log out, do so // This is a bit sloppy since you can't guarantee that $_GET['task'] // exists. I use a separate utility class to get the value safely, // which I left out here for brevity. if ($_GET['task'] == "logout" && $auth->checkAuth()) {

    $auth->logout();
    $auth->start();    // Restart the login (this must be here!)

} // If the second $auth->start() call is here instead of above, I get // the symptom you describe. // If the user is not already authenticated, they don't get to see // anything else if (! $auth->checkAuth()) {

    exit();    // We don't want to show anything but the login page

} ?> -------------------------------------- Jonathan Loran wrote:

Hi all, I'm more or less a newbie to PEAR and PHP. What is the canonical method to have a user sign out once they are authenticated with Auth_HTTP? I found the auth:logout() function, but it doesn't seem to actually log the user out. When I reload the secure page, no password is asked for. What am I missing? Thanks in advance for any guidance.
