  <p> This page demonstrates the SWFObject plugin. Do each of the following (one at a time) to see the plugin work: </p>
   <ul>
    <li>Uninstall your Flash Player or install a version less than 9.0.28</li>
    <li>Cause the SWF file to fail to load by deleting or renaming swfupload.swf (simulating a very slow or failed download)</li>
    <li>Disable JavaScript</li>
   </ul>
  <p>
   Each of these tests demontrate how these issues can be handled by SWFUpload and the SWFObject libraries.

核心处理程序php代码

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     = WF( . $fileName, "w");
    fwrite($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": "<?php echo session_id(); ?>"},

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。）
