WP Signon from external resource/php code

[TeckniX]

Wordpress has a lot of different functions available in the codec, such as the wp_signon.

The code to login a user from within the wordpress folder looks like:

$creds = array();
$creds['user_login'] = $username;
$creds['user_password'] = $password;
$creds['remember'] = true;
$user = wp_signon( $creds, false );
wp_set_current_user($user->ID);

If this is done outside of the wordpress user folder, by including the wp-config.php file

including the wp-config, like the following:
global $wpdb;
define('WP_USE_THEMES', false);
require_once '/path/to/www/blog/wp-config.php';
wp();

then the cookies aren't created successfully and you can't properly login/logout a user.

There are a log of constants that set this up, yet the cookies aren't set properly, you are missing the wordpress_logged_in_COOKIEHASH essential cookie.

Such flexible function should work properly
