我可以'；t使用Uploadify将文件上传到我的服务器上

我在尝试将文件上传到服务器时遇到问题。我使用uploadify插件将文件上传到我的服务器上，然后将文件名存储在数据库中。

问题是upmodify的行为就像文件已经上传，没有任何错误，但什么都没有上传。

我在Windows2008R2Server上运行PHP

以下是我处理实际上传的php代码。

<?php
require("../requires/LDAP_connection.php");
require("../requires/APP_configuration.php");
require("../requires/PHP_generic_functions.php");
//Include connection class
require('../classes/connection.php');
require('../requires/user_authentication.php');  //this file must be placed under the connection class NOT before
define('ROOT_SYS', dirname(__FILE__).'/');
// Define a destination
$targetFolder = '';
$verifyToken = '100';
$actualToken = '';
$fileTypes = array('jpg','jpeg','gif','png');
if(isset($_POST['upload_path'])){
    $targetFolder = $_POST['upload_path'];
}
if(isset($_POST['timestamp'])){
    $verifyToken = md5($_POST['timestamp']);
}
if(isset($_POST['token'])){
$actualToken = $_POST['token'];
}
if(isset($_POST['allowed_extentions'])){
    $types = explode(',', $_POST['allowed_extentions']);
    if(count($types) > 0 ){
        $fileTypes = $types;
    }
}

if (!empty($_FILES) && $actualToken == $verifyToken) {
    $tempFile = $_FILES['Filedata']['tmp_name'];
    $targetPath =  ROOT_SYS . $targetFolder;   //$_SERVER['DOCUMENT_ROOT']
    $new_filename = USER_ID . '_' . time() . '_' . str_replace(" ", "_", $_FILES['Filedata']['name']);
    $targetFile = $targetPath . $new_filename;
    // Validate the file type
    //$fileTypes = array('jpg','jpeg','gif','png'); // File extensions
    $fileParts = pathinfo($new_filename);  //str_replace(" ", "_", $_FILES['Filedata']['name'])
    if (in_array($fileParts['extension'],$fileTypes)) {
        move_uploaded_file($tempFile,$targetFile);
        echo trim($new_filename);
    } else {
        echo 'INVALID';
    }
}
?>

下面是我的javascript

<?php $timestamp = time();?>
    <script type="text/javascript">
    $(function() {
        $('#file_upload').uploadify({
            'formData'     : {
                'timestamp' : '<?php echo $timestamp;?>',
                'token'     : '<?php echo md5($timestamp);?>',
                'upload_path': 'add-ons/ticketing_system/uploads/',
                'allowed_extentions': 'jpg,jpeg,gif,PNG,JPG,png,zip,rar,doc,docx,cvs,xls,xlsx,txt'
            },
            'auto' : true,
            'swf'      : '../../includes/uploadify.swf',
            'uploader' : '../../includes/uploadify.php',
            'fileSizeLimit' : '10MB',
            'fileTypeExts' : '*.gif; *.jpg; *.JPG; *.png; *.PNG *.zip; *.rar; *.doc; *.docx; *.cvs; *.xls; *.xlsx; *.txt;',
            'onUploadSuccess' : function(file, data, response) {
                if(data != 'INVALID'){
                    $('#attached_files').append('<input type="hidden" name="attachments[]" value="'+ $.trim(data) +'" />');
                } else {
                    alert('Invalid File Type');
                }
            }
        });
    });
</script>

我做错了什么？为什么它没有上传任何内容，也没有给我任何错误？
