Signature images upload

[Ice Man_00]

Hi guys.

I have tried to make a upload script. What i really wanted it to di, was that i implented it to the board and when i fellow upload a file, the nickname will be the file name too.

But i can`t get it to work, so i ask here... please help ?!?! :)

Here`s the code:

<?php

$file_dir="/home/board/www/forums/images/sigs/";
$url_prefix="http://www.your.url/forums/images/sigs/";
$max_kilobytes = 2048;

if($userfile && $newname)
{
$userfile_name=basename($userfile_name);

if(stristr($userfile_name, ".php"))
{
die("Sorry you are not allowed to upload php-scripts.");
}

if ($userfile == "none") // image > $max_kilobytes
{
echo "Image rejected: exceeds max size ($max_kilobytes k) - please upload a smaller image";
} else {

if (file_exists($file_dir.$newname))
{
echo "Image rejected: a file called '$newname' already exists - please choose another name.";
} else {
if (copy($userfile, $file_dir.$newname))
{
unlink($userfile);
echo "File successfully uploaded. Paste this text:<br>";
echo "<textarea rows=\"2\" cols=\"60\">?$url_prefix$newname</textarea><br />";
echo "to place this image: <br><img src=\"$url_prefix$newname\">";
} else {
echo "Upload failed...";
}
}
}
}

?>
