     */
    function fn_set_page_as_front_for_loggedin_user( $value ) {
        if ( is_user_logged_in() ) {
            $value = \'page\';
            //page is set as front page
        }
        return $value;
    }
    add_filter( \'pre_option_show_on_front\', \'fn_set_page_as_front_for_loggedin_user\' );

    /**
     * If user is not logged in, set our static page to act as home page
     * @param $value
     * @return int
     */
    function fn_set_context_based_page_on_front( $value ) {

        if( ! is_user_logged_in() ) {
            return $value;
        }

        //for logged in user, use page id - in this case 56
        return 56;
        //change with your own page id.
    }
  add_filter( \'pre_option_page_on_front\', \'fn_set_context_based_page_on_front\' );
