<br><br>This will enable your ATK site to bypass the login page auto-logged-in as a guest user. Also, possibly allow guest users to view (readonly) some nodes or register a new user account to the system or to make other transactions in your site (example: feedbacks, testimonials).

'''Warning: This How-To has been reported to have problems with the recent version of ATK and is currently being updated.'''
}}

1. '''Create a profile''' (I used - ''"Guest Profile"'') for your guests. For a start, I have enabled only the "admin" access rights to the nodes I want guest users to see. And to enable user registration and other guest actions, I enabled the "add" access to my user node (or on a separate user registration node/table) and other actions on nodes that you may want guests to have access to.

2. '''Add a user''' (''"Guest Account"'') account with no username and password to your user table. This will be the initial account of anyone who visits your site and has not logged-in yet.

3. '''Assign''' the ''"Guest Profile"'' to the ''"Guest Account"''.

4. '''Edit ./config.inc.php''' to allow multiple authentications including "none". Here, I used the "none" authentication for guest users and "db" for registered users. Also, uncomment the $config_authorization, and set it the same as your second authentication type. This prevents ATK from loading "auth_none, db" (as in my $config_authentication) which results in a fatal error because atk does not handle yet multiple authorizations.

<syntaxhighlight lang="php">
$config_authentication = "none, db";
$config_authorization = "db";</syntaxhighlight>

5. '''Edit ./atk/security/class.auth_none.inc''' to disable logging-in of unknown accounts. Here, we only allow guests to login if there was no username entered when attempting to login.

<syntaxhighlight lang="php">
function validateUser($user, $passwd)
{
if ($user == "")
return AUTH_SUCCESS;
else
return AUTH_MISMATCH;
}
</syntaxhighlight>

6. '''Edit line 43-56 of ./top.php''' to change ''"Logged in as: <username> Logout"'' to ''"Members: Login"'' on the initial site visit.

<syntaxhighlight lang="php">
//Backwards compatible $content, that is what will render when the box.tpl is used instead of a top.tpl
$loggedin = ($g_user["name"]=="")? text("members").":" : text("logged_in_as", "", "atk").": &lsaquo;b&rsaquo;".$g_user["name"]."&lsaquo;/b&rsaquo;";
$content = '&lsaquo;br/&rsaquo;'.$loggedin.'   <a href="app.php?atklogout=1" target="_top">'.(($g_user["name"]=="")? ucfirst(atktext("login")) : ucfirst(atktext("logout"))).'</a> &lsaquo;br/&rsaquo;&lsaquo;br/&rsaquo;';
$top = $ui->renderBox(array("content"=> $content,
"logintext" => ($g_user["name"]=="")? atktext("members") : atktext("logged_in_as"),
"logouttext" => ($g_user["name"]=="")? ucfirst(atktext("login", "", "atk")) : ucfirst(atktext("logout", "", "atk")),
"logoutlink" => "index.php?atklogout=1",
"logouttarget"=>"_top",
"centerpiece"=>"",
"searchpiece"=>"",
"title" => atktext("app_title"),
"user" => $g_user["name"]),
"top");
</syntaxhighlight>

... and for those using the dropdown menu (ATK 5.7 - Nightly):

'''Edit line 63 of ./atk/menu/class.atkdropdownmenu.inc''' to point the logout link to ./index.php and render the logout link correctly.
<syntaxhighlight lang="php">
global $g_user; // added
$menu.=" &lsaquo;li&rsaquo;<a href='index.php?atklogout=1'>".(($g_user["name"]=="")? (atktext("members").": ".atktext("login")) : (atktext('logout')." ".$g_user["name"]))."</a>&lsaquo;/li&rsaquo;\n"; // edited
</syntaxhighlight>

7. '''Add''' to your language file the '''translation''' for ''"members"''
<syntaxhighlight lang="php">
"members" => "Members",
</syntaxhighlight>
