Here’s a quick tip! I was wandering around the web for the perfect solution to retrieve the current URL in a WordPress theme or plugin. I found a bunch of solutions for PHP, but not directly related to WordPress so I thought there has to be an easier way, and after a few hours of examining with global variables seems like I found it.
global $wp; $current_url = add_query_arg( $wp->query_string, '', home_url( $wp->request ) );
Beats all the
$_SERVER approaches and no need to identify whether the host is using SSL, etc. You can add a trailing slash to that with trailingslashit if you need to, and it looks much cleaner too. Hope you enjoy that, and thanks for tweeting ;)
