- <form id="form1" action="index.php" method="post" enctype="multipart/form-data">
- <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:
- 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 = $_FILES['Filedata']['tmp_name'];
- //开源代码phpfensi.com
- if (!move_uploaded_file($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);
- }
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($_POST['PHP_SESSIONID'])指定一下.
上传页的JS里面,可以获取当前的SESSION_ID的,例如上传页的JS中,代码如下:
post_params: {"PHPSESSID": "<?php echo session_id(); ?>"},
在验证的判断页,代码如下:
if (isset($_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.
