Wordpress check if user is logged in from non wordpress page

Question

I am using wordpress and I normally use:

if (!is_user_logged_in()){
   //something here
}

to detect if the wordpress user is logged in or now.

My problem is that I need to detect if the user is logged in to wordpress from a non-wordpress page.

My page is in the same directory as the other wordpress pages but is not page of wordpress.

How can I detect this from my page?

Answer 1

Simply place

define( 'WP_USE_THEMES', false );
include 'wp-load.php';

on to of your template files (before everything else). This loads the whole WP core.

Answer 2

this is untested by me, but please have a look at this article: Integrating Wordpress into an Existing Site

In essence I believe that if you use:

<?php require('/the/path/to/your/wp-blog-header.php');?>

..at the top of you (php) page you should be able to take advantage of the is_user_logged_in() function.
