来自iframe的电子邮件URL

我有一个联系表单，该表单应该发送一封电子邮件，其中包含用户当前正在观看的产品的链接，问题是我需要使用iframe，因为服务器不接受PHP文件，因此我需要这样做：

 $name = clearValue($_POST["name"]);
        $lastname = clearValue($_POST["lastname"]);
        $company = clearValue($_POST["company"]);
        $phone = clearValue($_POST["phone"]);
        $country = clearValue($_POST["country"]);
        $quantity = clearValue($_POST["quantity"]);
        $mail = ($_POST["mail"]);
        $message = clearValue(nl2br($_POST["message"]));
        $type_quote = clearValue($_POST["type"]);
        $page = currentPageURL();

$headers = "Content-type: text/html\r\nFrom: $fromMailStatus \r\nReply-To: $fromMailStatus";
    $body = file_get_contents("resources/mails/mail_newWebLead.htm");
    $body = str_replace("{name}",$name,$body);
    $body = str_replace("{lastname}",$lastname,$body);
    $body = str_replace("{company}",$company,$body);
    $body = str_replace("{phone}",$phone,$body);
    $body = str_replace("{country}",$iPais["nombre"],$body);
    $body = str_replace("{language}",$iLang["nombre"],$body);
    $body = str_replace("{quantity}",$quantity,$body);
    $body = str_replace("{email}",$mail,$body);
    $body = str_replace("{message}",$message,$body);
    $body = str_replace("{link}",$page,$body);
    $body = str_replace("{ip}",$ip_source,$body);

    mail($para,"New Web Lead",$body,$headers);

function currentPageURL() {
    $pageURL = 'http';
    if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
    $pageURL .= "://";
    if ($_SERVER["SERVER_PORT"] != "80") {
        $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
        } else {
        $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
    }
    return $pageURL;
}

此方法有效，但是它返回从中调用iFrame的页面，并且我需要原始URL，该怎么办？
