Question

这是我用于表单的PHP代码（多个文件上传）：

<?php
$to = "emailaddress@gmail.com";
$subject= "Request For Quote";
$todayis = date("l, F j, Y, g:i a") ;
$subject= "Request For Quote";
$name = $_POST['name'];
$lastname = $_POST['lastname'];
$email = $_POST['email'];
$cmname = $_POST['cmname'];
$message = "
Date ------- $todayis
Name ------ $name
Last Name ------- $lastname
Email ----------- $email
Company --------- $cmname
";
  $mime_boundary="==Multipart_Boundary_x".md5(mt_rand())."x";
        $headers = "From: $email\r\n" .
     "MIME-Version: 1.0\r\n" .
        "Content-Type: multipart/mixed;\r\n" .
        " boundary=\"{$mime_boundary}\"";
     $message = "This is a multi-part message in MIME format.\n\n" .
        "--{$mime_boundary}\n" .
        "Content-Type: text/plain; charset=\"iso-8859-1\"\n" .
        "Content-Transfer-Encoding: 7bit\n\n" .
     $message . "\n\n";
     foreach($_FILES as $userfile)
     {
        $tmp_name = $userfile['tmp_name'];
        $type = $userfile['type'];
        $name = $userfile['name'];
        $size = $userfile['size'];
        if (file_exists($tmp_name))
        {
           if(is_uploaded_file($tmp_name))
           {
              $file = fopen($tmp_name,'rb');
              $data = fread($file,filesize($tmp_name));
              fclose($file);
              $data = chunk_split(base64_encode($data));
           }
           $message .= "--{$mime_boundary}\n" .
              "Content-Type: {$type};\n" .
              " name=\"{$name}\"\n" .
              "Content-Disposition: attachment;\n" .
              " filename=\"{$fileatt_name}\"\n" .
              "Content-Transfer-Encoding: base64\n\n" .
           $data . "\n\n";
        }
     }
     $message.="--{$mime_boundary}--\n";
if (mail($to, $subject, $message, $headers))
 echo "Mail sent successfully.";
else
echo "Error in mail";
?>

现在我想添加一个多选选项框，如下所示：

        <select data-placeholder="Select Multiple Items" class="chosen-select" multiple>
            <option>Item 1</option>
            <option>Item 2</option>
            <option>Item 3</option>
            <option>Item 4</option>
        </select>

显然没有上传所选的选项，所以我尝试了这个：

<option name="option" type="text" id="option">Item 1</option>

添加：

$option= $_POST['option'];

但它不起作用。任何人都可以帮助我在这里，请添加多个选择到PHP代码。谢谢！

如果你想让php读取它，你需要为select元素添加一个name属性。还要确保它包含在表单中。

例如

  <select name="option[]" data-placeholder="Select Multiple Items" class="chosen-select" multiple>
            <option>Item 1</option>
            <option>Item 2</option>
            <option>Item 3</option>
            <option>Item 4</option>
        </select>

通过在name属性中添加括号，请求var成为一个允许您传递多个值的数组。
