多重选择的查询页面 - 邮寄功能

Question

其实我正在一个查询页面，我有多个选择选项，我希望邮件一次用户选择多个选项并提交表单。为此，我做了下面的代码，但未能明白的问题，请帮我的朋友...

这是HTML代码

<select id="lstFruits" name="product_drop[]" multiple="multiple"> 
<option value="Orange Color ">Orange Color </option> 
<option value="Red Color">Red Color</option> 
<option value="Black Color">Black Color</option> 
<option value="Purple Color">Purple Color</option> 
</select> 

而对于邮件功能，我用下面的代码PHP代码，正在工作和其他字段，如名称，不，cname，邮件&邮件正在接收邮件，但只是这个多选的东西是不来邮件。 prod = implode不工作..

<?php 
$name = trim($_POST['name']); 
$no = trim($_POST['no']); 
$cname = trim($_POST['cname']); 
$mail  = trim($_POST['mail']); 
$mess = trim($_POST['message']); 

if(isset($_POST['product_drop'])) 
{ 
$prod=implode(',',$_POST['product_drop']); 
} 


$redirect_to = 'https://www.google.com'; 
$a=""; 

$to = "[email protected]"; 
$subject = "Enquiry Received from Website"; 
$message = "Name: " . $name ."\r\nContact No.: " . $no ."\r\nCompany Name: " 
. $cname . "\r\nMessage: " . $mess . "\r\nProduct: " . $prod."";  

$from = "Website"; 
$headers = "From:" . $from . "\r\n"; 
$headers .="Cc: ". $a . "\r\n"; 


$headers .= "Content-type: text/plain; charset=UTF\n"; 


if(@mail($to,$subject,$message,$headers)) 
{ 
    header("Location: $redirect_to"); 
    exit; 
} 
?> 

在此先感谢！
