Introduce a `logout_redirect` filter

[johnbillion]

The login_redirect filter is applied to the redirect URL when a user logs in. There is no corresponding filter applied to the redirect URL when a user logs out.

Thoughts?

Why not, but you already can do this, even if it's a little tricky:

add_filter( 'wp_redirect', 'logout_redirect_filter' );
function logout_redirect_filter( $location ) {
	if ( isset( $_REQUEST['action'], $_REQUEST['redirect_to'] ) && 'logout' == $_REQUEST['action'] ) {
		$location = home_url( '/my-own-url/' );
	}
	return $location;
}

Thoughts?

I don't really have a problem with this, though I wonder if perhaps we should pass both the original value of redirect_to as well as the derived fallback, just as we do in the login_redirect filter.

[johnbillion]

Good point.

27617.2.patch​ passes the original 'redirect_to' value as well.

In 31417:

Introduce a logout_redirect filter so the redirect destination can be changed when a user logs out. Parameters:

• string $redirect_to The redirect destination URL.
• string $requested_redirect_to The requested redirect destination URL passed as a parameter.
• WP_User $user The WP_User object for the user that's logging out.

Fixes #27617
