有没有一种方法可以使用$_FILES在另一个页面上传递值？
下面是我的代码：

• test.php*：

<form id="form" method="post" enctype="multipart/form-data">
<input type="file" name="userfile" id="userfile">
    <input type="submit" id="submit" name="submit" value="Submit">
</form>

• submit.php*：

<?php 
    if (isset( $_SERVER['HTTP_X_REQUESTED_WITH'] )):

        if (!empty($_POST['name']) AND !empty($_POST['email']) AND !empty($_POST['comment'])) {
            $name = $_POST['name'];
            $mail = $_POST['email'];
            $message = $_POST['comment'];
            $ticket_id = $_POST['id'];
            $file = $_FILES['userfiles'];

            $comment->insertMessage($ticket_id,$message,$name);
        } 

        if(!empty($_FILES['userfile'])) {
            $comment->attachFile();
        }
?>
<?php
      endif
?>

如何使用$_FILES传递值？
