WordPress Toolbar: NO SHOW for specific users while on index page -

-

i show toolbar visitors of site, exception of; not logged in users\visitors, while on index page.

the following placed in function file works fine displaying toolbar visitors @ times.

add_filter( 'show_admin_bar', '__return_true' );

so hoping replacing meet added conditions...

    function show_bar() {          if ( ! isset( $show_admin_bar ) ) {               if ( ! is_user_logged_in() && is_home() ) {                    $show_admin_bar = __return_false;               } else {                    $show_admin_bar = __return_true;           }          }    $show_admin_bar = add_filter( 'show_admin_bar', '$show_admin_bar' );    return $show_admin_bar;     }

i don't think function being fired (no warnings or errors, no toolbar visitors. ). question is, there better way this, if not take function work?

thx
