<form enctype="multipart/form-data" class="vertical total_form"  method="post" action="send.php">

bp файла send не делаю никакого секрета. не могу найти как прикрепить файл, поэтому выкладываю ниже код

<?

// Mailer
require("mailer/phpmailer.inc.php");



$table = "<table border='1' cellpadding='6' cellspacing='0'>";

foreach($_REQUEST["data"] as $key => $data) {
if(strlen($key) > 2) {
$table .= "<tr><th colspan='2' align='left'>".$key."&nbsp;</th></tr>";
foreach($data as $f => $v) {
if(strlen($f) > 0) {

if(strlen($f) <= 2) {
$f = "Опция";
}

if(trim($v) == "") {
continue;
}

$table .= "<tr><td>".$f."&nbsp;</td><td>".$v."&nbsp;</td></tr>";
}
}
}
}

$table .= "</table>";




$mail = new phpmailer();
$mail->AddAddress("info@cargobroker.ru", "info@cargobroker.ru");
$mail->AddReplyTo("info@cargobroker.ru", "noreply@cargobroker.ru");
$mail->From = "info@cargobroker.ru";
$mail->FromName = "Калькулятор по страхованию речных судов";
$mail->Subject = "Расчет калькулятора";
$mail->IsHTML(true);
$mail->CharSet = "utf-8";
$mail->Body = "\n\r\n\r".$table;
$mail->Send();

header("Location: ./?ok");


?>

посмотрите примеры по работе с классом phpmailer
у вас в коде даже намёка нету на прикрепление файлов

Игорь, в phpmailer есть аттачи

кто "они"?)))

вот попытка

$mail = new phpmailer();
$mail->AddAddress("info@cargobroker.ru", "info@cargobroker.ru");
$mail->AddReplyTo("info@cargobroker.ru", "noreply@cargobroker.ru");
$mail->From = "info@cargobroker.ru";
$mail->FromName = "Калькулятор по страхованию речных судов";
$mail->Subject = "Расчет калькулятора";
$mail->IsHTML(true);
$mail->CharSet = "utf-8";
$mail->Body = "\n\r\n\r".$table;
$mail->Send();

if($_FILES['file']['error'] === 0)
{
$ext = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION);
$mail -> attacheFile($_FILES['file']['tmp_name'], $_FILES['file']['name']);
}

header("Location: ./?ok");

а как это реализовано в примере выше видишь?

Предлагаю метод с указанием ссылок на скачивания файлов.
Возможно получиться:
Создаем папку "files" в главной директории. Путь получится такой - http://marine.cargobroker.ru/files/
В форму, где находятся поля для заполнения,заменяем строку:

<form class="vertical total_form"  method="post" action="send.php"> 

на

<form enctype="multipart/form-data" class="vertical total_form"  method="post" action="send.php">
Выберете 1-н или несколько файлов<br />
<input type="file" min="1" max="50" name="file[]" multiple="true" size="100" style="cursor: pointer" />

Ну и дополняем файл send.php:

<?

// Пробуем сохранить файлы:
$ms='';
$exit=true;
$i=0;
while ($exit){
	if(!empty($_FILES['file']['tmp_name'][$i])) { 
	$tmp_name = $_FILES['file']['tmp_name'][$i]; 
	move_uploaded_file($tmp_name, '/files/'); // не забудьте создать папку files
$ms.='Файл номер '.$i.'. <a href="http://marine.cargobroker.ru/files/'.$tmp_name.'">Ссылка</a>';
	} else {exit=false;}
$i++;
}
