I have an upload script and it” saving the filename with the original filaname+temp name. I need it to be changed as just temp name because special characters are causing problems and if there is a spacial character in the filename browsers can not read the image.

Here is the code:

it’s funny but all that code you pasted in there is totally irrelevant to your problem..

Anyhow I went and looked up this class for you here, http://www.xoops.info/doc/nav.html?_classes/index.html and researched the problem..

After this – $uploader = new XoopsMediaUploader

slide in this:
$uploader->setTargetFileName($value);

Where $value is the random file name you wish to use.
A very simply way to create a random string would be:
$value = mt_rand(5, 15);

Keep in mind you will need to concat the extension onto that random number!!!
