chdir('./YOUR_FORUM_FOLDER_NAME');

define('CVD', (($getcwd = getcwd()) ? $getcwd : '.'));

require_once(CVD . '/global.php');



$vbulletin->input->clean_array_gpc('p', array('ajax' => TYPE_BOOL));



if($vbulletin->GPC['ajax'] == true)    

{

    $result = array(

        'username' => $vbulletin->userinfo['username'],

        'userid' => $vbulletin->userinfo['userid'],

        'userpost' => $vbulletin->userinfo['posts'],

     );

    echo json_encode($result);

}

?>

2- jquery_cookie.js
Create this file using the code from this https://raw.github.com/carhartl/jquery-cookie/master/jquery.cookie.js

3- jquery_vbulletin.js
Change XXX with any another prefix wich do you want

Code:

$(document).ready(function () 
{
    $.ajax({
        url:'vbconnect.php',
        type:'POST',
        data:'&ajax=1',
        cache:false,
        async:false,
        dataType:'json',
        success:function(result){
            $.cookie('XXXuserid', result['userid'], { expires: 7, path: '/' });
            $.cookie('XXXusername', result['username'], { expires: 7, path: '/' });
            $.cookie('XXXuserpost', result['userpost'], { expires: 7, path: '/' });},
        error:function(){
            $.cookie('XXXuserid', '', { expires: 7, path: '/' });
            $.cookie('XXXusername', '', { expires: 7, path: '/' });
            $.cookie('XXXuserpost', '', { expires: 7, path: '/' });}

<?php



$vb_userid    = $_COOKIE['XXXuserid'];

$vb_username  = $_COOKIE['XXXusername'];

$vb_userpost  = $_COOKIE['XXXuserpost'];



if($vb_userid)

{

    // The guest is logged in 

    // Exemple

    $output = "Welcome $vb_username";

}

else

{

    // The guest is not logged in 

    // Exemple

    $output = "Welcome " . $_SERVER['REMOTE_ADDR'] . " , you are not connected to the forum";

}



?>

5- Your output (html / php)

Code:

<script src="http://code.jquery.com/jquery-latest.js"></script>
<script src="your/path/to/javascript/directory/jquery_cookie.js"></script>
<script src="your/path/to/javascript/directory/jquery_vbulletin.js"></script>
<?php echo $output; ?>
