Checking user logged in or not

[samser_m]

Hi,
1) I want to add a php file with some fields which user should fill up and save on our database.

2) I have to check whether user is currently logged in or not. If yes then user will be able to see the php page otherwise not.

3) I have to retrieve userid and email from "user" table

4) Finally all the details with userid, email will be saved on a new table.

Thanks in advance.

Regards,
Samser

Here a basic example

<?php

define('THIS_SCRIPT', 'script');

include('./global.php');

if ($vbulletin->userinfo['userid'] == 0)
{
print_no_permission();
}

echo 'Email: '. $vbulletin->userinfo['email'] ."<br />\n";
echo 'Userid: '. $vbulletin->userinfo['userid'];

?>

Thanks for reply!
is this code would work for both version 3.0.3 and 3.6.1? I think no. because
I have tested in 3.0.3 but it's not working.

First, I have to include header and footer of vBulletin with my script.
Secondly, I need to check whether user is logged in or not
Then I have to retrieve username, email from database.

Eearly reply is appretiated.
Regards
