        while($row2 = $db->get_row($get_regions)){
            $get_cities = $db->query("SELECT * FROM ".PREFIX."_shop_cities WHERE god='$row2[id]' AND type='2'"); # города
            while($row3 = $db->get_row($get_cities)){
                $tpl->load_template("eshop/citylist.tpl");
                $tpl->set("{city_name}", "<li>".$row3["name_ru"]."</li>");

我试着这样做:

$get_all = $db->query("SELECT a.name_ru as Country, b.name_ru AS Region, c.name_ru AS City FROM dle_shop_cities AS a JOIN dle_shop_cities AS b ON a.id = b.god AND b.type = 1 JOIN dle_shop_cities AS c ON b.id = c.god AND c.type = 2");   # Берем страны
while($row = $db->get_row($get_all)){

            $tpl->load_template("eshop/citylist.tpl");
            $tpl->set("{city_name}", "<li>".$row["City"]."</li>");
            $tpl->compile("cities");
            $tpl->clear();

        $tpl->load_template("eshop/regionslist.tpl");
        $tpl->set("{region_name}", $row[Region]);
            $tpl->set("{cities}", $tpl->result["cities"]);
        $tpl->compile("regions");
        $tpl->clear();

    $tpl->load_template("eshop/countrylist.tpl");
    $tpl->set("{name_country}", $row["Country"]);
    $tpl->set("{regions}", $tpl->result["regions"]);
    $tpl->compile("citylist");
    $tpl->clear();
}
