SWFUpload   v2.2.0   SWFObject Demo      This page demonstrates the SWFObject plugin.  Do each of the following (one at a time) to see the plugin work:          Uninstall your Flash Player or install a version less than 9.0.28      Cause the SWF file to fail to load by deleting or renaming swfupload.swf (simulating a very slow or failed download)      Disable JavaScript           Each of these tests demontrate how these issues can be handled by SWFUpload and the SWFObject libraries.              Upload Queue         0 Files Uploaded                                    SWFUpload is loading. Please wait a moment...          SWFUpload is taking a long time to load or the load has failed.  Please make sure that the Flash Plugin is enabled and that a working version of the Adobe Flash Player is installed.

核心处理程序php代码

 代码如下

代码如下

复制代码

if (isset($_FILES["Filedata"]) || !is_uploaded_file($_FILES["Filedata"]["tmp_name"]) || $_FILES["Filedata"]["error"] != 0) {     $upload_file = $_FILES['Filedata'];     $file_info   = pathinfo($upload_file['name']);     $file_type   = $file_info['extension'];     $save        = 'image/' . md5(uniqid($_FILES["Filedata"]['name'])) . '.' . $file_info['extension'];     $name        = $_FILES['Filedata']['tmp_name'];       if (!move_uploaded_file($name, $save)) {         exit;     }       //将数组的输出存起来以供查看     $fileName = 'test.txt';     $postData = var_export($file_info, true);     $file     = fopen('' . $fileName, "w");     fwrite($file,$postData);     fclose($file); }

复制代码

if (isset($_FILES["Filedata"]) || !is_uploaded_file($_FILES["Filedata"]["tmp_name"]) || $_FILES["Filedata"]["error"] != 0) {     $upload_file = $_FILES['Filedata'];     $file_info   = pathinfo($upload_file['name']);

    $file_type   = $file_info['extension'];
    $save        = 'image/' . md5(uniqid($_FILES["Filedata"]['name'])) . '.' . $file_info['extension'];

    $name        = $_FILES['Filedata']['tmp_name'];

 

    if (!move_uploaded_file($name, $save)) {

        exit;

    }

代码如下	复制代码
post_params: {"PHPSESSID": ""},

 

    //将数组的输出存起来以供查看

    $fileName = 'test.txt';

代码如下	复制代码
if (isset($_POST["PHPSESSID"])) {             session_id($_POST["PHPSESSID"]);         }

    $postData = var_export($file_info, true);

    $file     = fopen('' . $fileName, "w");

    fwrite($file,$postData);

    fclose($file);

}

swfUpload注意事项swfuplaod在上传时，会新开一个进程，和原来的进程不一致，要解决这个问题，需要指定session_id，然后在登录页面判断，如果有post过来的session_id，那么就用函数session_id( $_POST['PHP_SESSIONID'])指定一下。上传页的JS里面，可以获取当前的SESSION_ID的。例如上传页的JS中：

 代码如下

复制代码

post_params: {"PHPSESSID": ""},

在验证的判断页中：

代码如下

复制代码

if (isset($_POST["PHPSESSID"])) {            session_id($_POST["PHPSESSID"]);        } （这一段是网上的注释：在带有Session验证的网站后台中SWFUpload无法正常工作，这是因为SWFUpload在上传时相当于重新开辟了一个新的Session 进程，因此无法与原有程序的Session保持一致，这就需要在上传时传递原有程序的SessionID，根据它来“找回”其应有的Session。）完整实例下载地址:http://file.php100.com/download/2013/05/14/swfupload.zip http://www.bkjia.com/PHPjc/444604.htmlwww.bkjia.comtruehttp://www.bkjia.com/PHPjc/444604.htmlTechArticleswfupload是一个flash插件它可以结合php来快速实现图片文件无刷新上传，同时还可以批量上传图片，下面我来给大家介绍PHP swfupload图片文件上...
