I've been searching for some WP specific way to detect any referrer. Have an idea? I know how to do that in PHP but I just want to know if there's some WP function to do that?
EDIT: here is what I 'm trying to test =>
$referer = wp_get_referer(); if ( strpos($referer ,'http://wordpress.org') !== false ) echo 'you come from wordpress.org';
