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"]))

答案 0 :(得分：0)
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";

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

$headers .= "name = ".$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" .
