Logout with hash

[ChristianAlfredsson]

I have this for my site: https://www.vbulletin.com/forum/blog...n-your-website

In the end it says

      else     {         echo 'Already logged in';     }  

I would like to have a link that can logout.

I have tried this

$hash = vB5_Cookie::get('password', vB5_Cookie::TYPE_STRING);
echo '<a href="https://www.zoopet.com/forum/auth/logout?logouthash=' . $hash . '" class="btn btn-default">Logout</a>';  

But there is no value to $hash. Is there a good way to get that value.

Try this:

$api = Api_InterfaceAbstract::instance();
$user = $api->callApi('user', 'fetchUserinfo', array());
echo '<a href="https://www.zoopet.com/forum/auth/logout?logouthash=' . $user['logouthash'] . '" class="btn btn-default">Logout</a>';  

This code is untested but I think it will work.

[ChristianAlfredsson]

Now the code is tested. It works great. Thank you

Glad to be of help.

I got the full code working with login/logout on external pages on Zoopet now. Do you want it and share it?

Sure you can post it here. Thanks.

Edited code to wrap in [PHP] BBCode tags for readability
