Re: Create Random Name to uploaded file

Best method is to use a combination of time, md5 and substr.. the following code will generate a prefix of 7 chars..

$prefix = substr(md5(time()),0,7);

Thank you.

@ghia .. thx for the link but that did not help me , i already know how to use the uploader class , I just Can not figuer Out how to rename the file to any random name.


@wishcraft .. Thx .. but i do not know how to apply that in my code .

I tried like this.

$prefix = substr(md5(time()),0,7);
$uploader = new XoopsMediaUploader(XOOPS_ROOT_PATH . "/" . "modules/test/upload/", $allowed_mimetypes, $maxfilesize);
if ($uploader->fetchMedia($_POST["xoops_upload_file"][0], $prefix)) {

Try:
$prefix = substr(md5(time()),0,7); 
$uploader = new XoopsMediaUploader(XOOPS_ROOT_PATH . "/" . "modules/test/upload/", $allowed_mimetypes, $maxfilesize); 
if ($uploader->fetchMedia($_POST["xoops_upload_file"][0])) { 
    $uploader->setTargetFileName($prefix.$uploader->mediaName); // ADDED | UPDATED
    if (!$uploader->upload()) {


Didn't try it but i think it should work.

Thank you Dylian ,

But that DID not work.

Fatal error: Call to undefined function setTargetFileName()


i have included uploader.php in the code , but for some reason it dose not Recall the settargetname Function.

See my example... (It adds the original filename and the extension)

[edit] This is the updated line in my original post:
$uploader->setTargetFileName($prefix.$uploader->mediaName);
