多重選擇的查詢頁面 - 郵寄功能

Question

其實我正在一個查詢頁面，我有多個選擇選項，我希望郵件一次用戶選擇多個選項並提交表單。爲此，我做了下面的代碼，但未能明白的問題，請幫我的朋友...

這是HTML代碼

<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> 

而對於郵件功能，我用下面的代碼PHP代碼，正在工作和其他字段，如名稱，不，cname，郵件&郵件正在接收郵件，但只是這個多選的東西是不來郵件。 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@gmail.com"; 
$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; 
} 
?> 

在此先感謝！

</form> 
<?php 
if($_POST){

$values = implode(",", $array);
