Title: if statement for login check? [SOLVED]
Post by: ROUBOS on July 02, 2012, 20:15:40

Hi,
I've used the if statement to check if we're on a certain component page in order to display or hide part of the template, is there an if statement to check wether the user is loged on and display a logout button?
I want to use a login and a logout button. So that when the user is loged on, then the logout button appears.

any thoughts???

thanks.

Hi Roubos,
Yes you can do that with this way :
if ($my->id) {
echo '<img src="logout.png" alt="Log out" width="300" height="50" />'."\n";
} else {
echo '<img src="login.png" alt="Log out" width="300" height="50" />'."\n";
}

In case that you are going to include the above piece of code at the index.php file of your template then there is no need to define the global variable $my. In any other case you should define it like this :
global $my;

On Elxis Nautilus relative way :
if (eFactory::getElxis()->user()->gid  != 7) {
echo '<img src="logout.png" alt="Log out" width="300" height="50" />'."\n";
} else {
echo '<img src="login.png" alt="Log out" width="300" height="50" />'."\n";
}

*Set the exact width and height of your image source inside img tag.

Checking access level value, to determine if a user is logged in or not, is not always safe on Nautilus.
You better check uid (user id, greater than zero for elxis users) or gid (group id, unequal to 7 - guests- and optionally to 6 - external users).

Conclusion
$elxis->user()->uid > 0 The user is logged in via Elxis Authentication.
$elxis->user()->uid = 0 The user is a guest or logged in via external authentication provider (LDAP, twitter, gmail, etc).

$elxis->user()->gid == 7 The user is a guest
$elxis->user()->gid == 6 The user is  logged in via external authentication provider.
else the user is logged in via Elxis authentication.

Right Datahell! It was my fault. It's totally recommended the use of either uid or gid .
