I got this file, but i got this error and i don't get why that happens.

Notice: Undefined index: uploaded in C:\wamp\www\insert\insert2.php on line 25.
"$ext = findexts($_FILES['uploaded']['name']) ;"

Code:


			

<?php
$connection = mysql_connect("localhost","root","");
if (!$connection) {
    die("wrong connection: " . mysql_error());
}


$db_select = mysql_select_db("images",$connection);
if (!$db_select) {
    die("error: " . mysql_error());
}
?>
<?php

function findexts ($filename)
{
$filename = strtolower($filename) ;
$exts = split("[/\\.]", $filename) ;
$n = count($exts)-1;
$exts = $exts[$n];
return $exts;
} 


$ext = findexts($_FILES['uploaded']['name']) ;  //here is the error
$ran = rand () ;
$ran2 = $ran.".";
$target = "C:/wamp/www/images/";
$target = $target . $ran2.$ext; 


if(isset($_POST['submit']))
{
if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target))
{
echo "The file has been uploaded as ".$ran2.$ext;
}
else
{
echo "Sorry, there was a problem uploading your file.";
}

$rename = $ran2.$ext;
$query = "INSERT INTO images (name) VALUES ('$rename')";
mysql_query($query) or die('Error, query failed : ' . mysql_error());
}
?>
