Unable to upload file with same name assitance required please help

[bluileo]

Hi People

 

I have managed to get my hands on this script and its perfect but unfortunately it will not let me upload a file with the same name as a file that already exists.

Unfortunately I am a complete newbie with php and although I am learning slowly this seems to be beyond my reach.

 

Can someone please tell me what I need to remove / adjust to be able to upload a file with the same name and for that to overwrite the original

 

The source code is below, any and all help greatly appreciated

This script is distributed under the licence conditions on the website http://rrwh.com/scripts.php

 

This script is a simple interface to allow you to upload files to a configured directory on your server.  It will additionally automatically create sub-directories if you want it to.  Additionally, It will let you do a directory listing of the base directory or any specified sub-directory.

 

You only need to modify the $password and $dir variable and ensure that the directory exists on the server and the permission is set to 777

 

You may want to modify the $types if you wish to allow other file types to be uploaded - Be careful not to allow dangerous files to be uploaded to your server.

change this line:

if ((in_array($_FILES['upload']['type'], $types)) and (!file_exists($fullpath.$clean_name))){ 

 

to this:

if ((in_array($_FILES['upload']['type'], $types))){
