我有一段wordpress的php代码。它不起作用。我想在另一个add\\u操作下执行一个add\\u操作。但下的add\\u操作不起作用！

function no_reminder() {
    echo "no_reminder function is active";
    add_action(\'admin_menu\',\'no_reminder\');

    remove_action( \'admin_notices\', \'update_nag\', 3 );
}

add_action(\'admin_menu\', \'custom\');
function custom() {
    add_menu_page(\'settings\', \'settings\', \'8\', \'custom\', \'customfunc\');
}

function customfunc(){
    $wpp_rg = get_option(\'wpp_rg\');
    if ($_POST[\'wpp_submit\']):
        update_option(\'wpp_rg\',$_POST[\'wpp_rg\']);
    endif;
    $farzad = get_option(\'wpp_rg\');
    /******************** IF1 ***********************/
    if ($farzad==1) {
        do_action(\'no_reminder\');
        no_reminder();
        echo "If active";
    }
    if ($farzad==2) {
        echo "IF Not Active";
    }
/******************** IF1 ***********************/
