我的联系表单有些麻烦，我想添加选项以选择多个附件。请帮我重建一下。使用单一选择附件一切正常，但我不知道如何添加多附件选项。

PHP代码：

<?php
if($_POST)
{
    $to_Email       = "MyDomain"; //Replace with recipient email address
    $from_Email     = "MyDomain"; //From email address (eg: no-reply@YOUR-DOMAIN.com)
    $subject        = 'MyDomain'; //Subject line for emails

    //check if its an ajax request, exit if not
    if(!isset($_SERVER['HTTP_X_REQUESTED_WITH']) AND strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') {

        //exit script outputting json data
        $output = json_encode(
        array(
            'type'=>'error', 
            'text' => 'Request must come from Ajax'
        ));

        die($output);
    } 

    //check $_POST vars are set, exit if any missing
    if(!isset($_POST["userName"]) || !isset($_POST["userEmail"]) || !isset($_POST["userPhone"]) || !isset($_POST["userMessage"]) || !isset($_POST["userMarka"]) || !isset($_POST["userModel"]) || !isset($_POST["userRocznik"]) || !isset($_POST["userCena"]))
    {
        $output = json_encode(array('type'=>'error', 'text' => 'Puste pole w formularzu.'));
        die($output);
    }

    //Sanitize input data using PHP filter_var().
    $user_Name        = filter_var($_POST["userName"], FILTER_SANITIZE_STRING);

也许你帮忙创造 $ encoded_content，$ file_type和$ file_name作为数组。

结束此atachment文件的数组中的每个值，并且您可以为每个元素写入新标题

foreach($encoded_content as $key => $content) {
    $headers .= "Content-Type:  ".$file_type[$key]."  ";
    $headers .= "name = ".$file_name[$key]."\r\n";
    $headers .= "Content-Disposition: attachment\r\n";
    $headers .= "Content-Transfer-Encoding: base64\r\n\r\n";
    $headers .= $content."\r\n";
}

现在我的代码看起来像它，但它不起作用

if($file_attached) //continue if we have the file
{

    # Mail headers should work with most clients (including thunderbird)
    $headers = "MIME-Version: 1.0\r\n";
    $headers .= "X-Mailer: PHP/" . phpversion()."\r\n";
    $headers .= "From:".$from_Email."\r\n";
    $headers .= "Subject:".$subject."\r\n";
    $headers .= "Reply-To: ".$user_Email."" . "\r\n";
    $headers .= "Content-Type: multipart/mixed; boundary=".md5('boundary1')."\r\n\r\n";

    $headers .= "--".md5('boundary1')."\r\n";
    $headers .= "Content-Type: multipart/alternative;  boundary=".md5('boundary2')."\r\n\r\n";

    $headers .= "--".md5('boundary2')."\r\n";
    $headers .= "Content-Type: text/plain; charset=utf-8\r\n\r\n";
    $headers .= $mail_body."\r\n\r\n";

    $headers .= "--".md5('boundary2')."--\r\n";

    $headers .= "--".md5('boundary1')."\r\n";

    foreach($encoded_content as $key => $content) {
    $headers .= "Content-Type:  ".$file_type[$key]."  ";
    $headers .= "name = ".$file_name[$key]."\r\n";
    $headers .= "Content-Disposition: attachment\r\n";
    $headers .= "Content-Transfer-Encoding: base64\r\n\r\n";
    $headers .= $content."\r\n";
}

    $headers .= $encoded_content."\r\n";
    $headers .= "--".md5('boundary1')."--"; 

}else{
    # Mail headers for plain text mail
    $headers = 'From: '.$from_Email.'' . "\r\n" .
    'Reply-To: '.$user_Email.'' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();
