secure AJAX update.php with init.php

[emanresu]

I have a page that calls update.php via jQuery whenever a input field is changed. How do I check if a user is logged in? do I have to also load init.php at the top of update.php?

I currently use the following code:

<pre>

Code:

<?php
require_once 'users/init.php';
if($user->isLoggedIn()){
   //some script
}
else{
echo 'go away!';
}
?>

</pre>


But I wonder if this is the correct way or if there is a better way.
