Any advise on this would be great...

With this script, a user can upload some images to a folder on the server.
The images either have the same name when uploaded or they are randomized. What I need, is for the images to keep their original file names but have the username of the person before them.

i.e user99_image1.jpg user99_image2.jpg and so on.

to get to this upload page the user has to be signed in so Im guessing (and only guessing mind...!) that it will be somethig to do with changing

$fileName = $_FILES[file][name][$i];

to something like

$fileName = $_SESSION[LOGIN_NAME][name][$i];

or something like that??

PHP Code:

    # of keeping a files name or randomly renaming it.
    # Remember, there maybe a a upload limit set by the server of 2MB, you can change this by changing the php.ini if you have access

What would probably work is this:

Change $newLocation = VAR_UPLOAD_DIRECTORY.$fileName;
to $newLocation = VAR_UPLOAD_DIRECTORY.$_SESSION[LOGIN_NAME].'_'.$fileName;

No, uploads with the original filename ok but dosn't put the login name before it...

** EDIT **

Yep, got it working now, needed the ' ' around

$_SESSION['LOGIN_NAME'].

Cheers for you help Insensus

I don't know in what variable the login name has been stored, but you kinda said it was in $_SESSION[LOGIN_NAME]. If it is in something else, you should replace $_SESSION[LOGIN_NAME] with the variable it is in, for the suggestion I made.

yeah it was my mistake in the original post! (TP added)

Another question... Would it be possible to have a confirmation email sent to me when the user uploads new images? posiibly containing their username in the email as well?

You can use the mail() function for that purpose.
Exact details are on the following page: http://php.net/manual/en/function.mail.php

Often emails sent by this function land in your spam folder, but I've struggled with the problem for quite some time and I haven't found a good fix yet. :P
