Note: The original post wouldn’t work for WordPress on sub-domains, so I’ve updated it to include a solution that will
The other day I needed to get the current url the user was on – and I was convinced that there would be a better way than handling $_SERVER directly.
I found this solution by Konstantin Kovshenin, but which unfortunately gave me
http://example.com/blog/category/cata1?category_name=cata1
when on
http://example.com/blog/category/cata1
Now add_query_arg, when passed no url uses the current url but, unfortunately, when on www.example.com/page/subpage/ it gives you: /page/subpage/. To get around that, you can use home_url.
To get the ‘current url’ in WordPress:
$current_url = home_url(add_query_arg(array()));
Unfortunately if you WordPress install lives on a subdomain this won’t work, since:
home_url()gives you something likewww.example.com/blogadd_query_arg(array())gives you something likeblog/page/subpage
So you get a repeat of blog. A more general solution would be
$current_url = home_url(add_query_arg(array(),$wp->request));
This is what I wanted. Thanks Stephen 🙂
This is perfect, Konstantin Kovshenin solution was not good for me, I had the same problem as you.
This worked perfectly, thank you!
If you’re using this in distributed code (i.e. plugin or theme), you also need to check whether permalinks are in use. If they’re not, you need to pass the query string to add_query_arg. Example:
global $wp, $wp_rewrite;
$query_args = $wp_rewrite->using_permalinks() ? array() : $wp->query_string;
$current_url = esc_url_raw( home_url( add_query_arg( $query_args, $wp->request) ) );
Seems like there should be a nicer way of doing this.
Cheers,
