Upload form question

Anon

I have a page called upload_form.html that allows a user to selce a file to upload. This HTML file then re-directs the user to do_upload.php where the file is actually uploaded.

Here is the coding for the do_upload.php page. I need to know how to make it so when someone tries to upload a file that is already uploaded, the file adds a 1, or 2 or _3 to the end so that the file does not get over-writen. Can anyone help me do this?

if ($guide1_name != "") {

      @copy("$guide1", "D:/webspace/theheadgamster/gamesteronline.com/www/uploads/$guide1_name")
               or die("Couldn't copy the file.");

} else {
die("No input file specified");

}

Hi,

You can allways check if the file is already created by using the function file_exists($filename);

so:
if(file_exists("UPLOAD_DIRECTORY/$uploaded_file")) {
for($i=0;;$i++) {
$new_filename=$uploaded_file."_$i";
if(!file_exists("UPLOAD_DIRECTORY/$new_filename")) break;
}
}

The above does what you asked for: If the file exists, it renames it to uploaded_filename_1,2,3...

Actually, uploaded_filename_0,1,2,_3

but if you want it to start from 1, just change

for($i=0;;$i++) to
for($i=1;;$i++)

i put that new code in just now, and the code still works, but it just doesn't add the _1 etc. to an existing file, it still overwrites it...

could you fix the PHP for me and then post it? I am new at PHP, and started in my free time like 4 days ago...
