Return to where the user was, after log out

by

I know how to direct logged out user to a particular page or a URL, like:

<a href="https://wordpress.stackexchange.com/questions/184731/<?php echo wp_logout_url( home_url() ); ?>">Log out</a>

But if I want the user to redirect to the URL where he/she just was, what can I do?

Though I’m not knowledgeable about wp_get_referer(), but I tried:

<?php $redirect_to = wp_get_referer() ? wp_get_referer() : home_url(); ?>
<a href="https://wordpress.stackexchange.com/questions/184731/<?php echo wp_logout_url( $redirect_to ); ?>">Log out</a>

and

<?php $redirect_to = $_SERVER['HTTP_REFERER'] ? $_SERVER['HTTP_REFERER'] : home_url(); ?>
<a href="https://wordpress.stackexchange.com/questions/184731/<?php echo wp_logout_url( $redirect_to ); ?>">Log out</a>

with no luck. 🙁

It’s always taking me to the home_url().

You get the current path with remove_query_arg( '' ). Combine it with site_url(), and you have the full current request URI:

$url = untrailingslashit( site_url() );
$url .= remove_query_arg( '' );

Be aware that remove_query_arg() doesn’t return a sanitized value, so you have to use esc_url() if you want to print it to a page. Otherwise, someone could inject malicious code into your site in an URL parameter.

wp_get_referer() is for form submissions, it looks for a request parameter _wp_http_referer and is not relevant in your case.
