How to add a prefix to a file before upload?

Question

CMS (Modx Evolution) that I`m currently using has ability to print some informations into site (like date/username etc.). I want to use those functions to work with plupload.

Is it possible to add a prefix or completely rename file after (or before uploading) to server trough plupload depending on which user is actually logged in?

Example:

• user uploads file test.txt,
• on server it will look username_test.txt

Answer 1

try this

<?php
$username = 'username';
$tmp_name = $_FILES["file"]["tmp_name"];
$name = $username.$_FILES["file"]["name"];
move_uploaded_file($tmp_name, "$uploads_dir/$name");
?>

Answer 2

Upload the file first then rename it

<?php rename("/tmp/test.txt", "/tmp/".$usernameVar."_test.txt"); ?>

Answer 3

You'll have access to the username using $modx->getLoginUserName() http://rtfm.modx.com/display/Evo1/getLoginUserName

Either set the filename in the plupload config (I think using the file_data_name config option), or rename it server-side after it's been uploaded.
