PHP文件上传，重命名文件，然后在“成功上传”页面上返回新文件名？

Question

I'm trying to return the name of a file uploaded using PHP after changing image files name upon uploading it.

I thought I could create a $_session['image_name'] and then call that session up on the subsequent "successful upload" page. I can't seem to get it correct. I need the name so that I can store it in the mysql database. Here's the part of my upload code that does the renaming and my attempt at creating a session:

/

/ make a unique filename for the uploaded file and check it is 
// not taken... if it is keep trying until we find a vacant one
$now = time();
while(file_exists($uploadFilename = $uploadsDirectory.$now.'-'.$_FILES[$fieldname]['name']))
{
    $now++;
$_SESSION['image_name'] = $uploadsDirectory.$now.'-'.$_FILES[$fieldname]['name'];
}

On my successfulUpload php page I was returning:

<p>Congratulations! Your file <? echo $_Session['image_name']; ?> upload was successful</p>

I have session_start(); at the very top of both the uploadProcessing code and the Successful uploads page.

Thanks for any help!

我现在看到，在您的成功页面上，应该将$ _SESSION大写。
