I have a site that uses wordpress for community purposes, it is installed under subdirectory "mysite/community" but when I try to call wordpress functions into "mysite" I cannot retrieve the logged user.
Here's my sample code:
require $xcart_dir . DIR_COMMUNITY . '/wp-load.php';
wp_get_current_user();
if ( 0 == $current_user->ID ) {
echo "Not logged in";
} else {
echo "Logged in";
}
Cookies can contain a Path, this is probably what you are looking for:
http://codex.wordpress.org/Editing_wp-config.php#Additional_Defined_Constants
To allow the cookie for all path on the domain, use define('COOKIEPATH',"/");
.
You can also set the cookie domain in wp-config.php:
http://codex.wordpress.org/Editing_wp-config.php#Set_Cookie_Domain
Use ".example.com"
to allow the cookie for all subdomains of example.com.
This plugin does exactly that,
http://wordpress.org/plugins/root-cookie/
Although I highly recommend yscik's solution to edit wp-config, in case you do not have access to the wp-config.php you can use this plugin.
