images being written over?

[Michdd]

I have a script that used to upload images, and I have something in it that is supposed to be changing then URL that it's uploaded to if that URL is already taken, however, it's not working, it's just overwriting the other image. Can anyone help me out?

 

The file:

 

<?php


   // Configuration - Your Options
      $allowed_filetypes = array('.jpg','.gif','.bmp','.png','.JPG','.GIF','.BMP','.PNG'); // These will be the types of file that will pass the validation.
      $max_filesize = 2024288; // Maximum filesize in BYTES
      $upload_path = 'images/'; // The place the files will be uploaded to (currently a 'files' directory).
  $auth = "0";
  $auth = $_POST['auth'];
  $password = $_POST['password'];

   $filename = $_FILES['userfile']['name']; // Get the name of the file (including file extension).
   $ext = substr($filename, strpos($filename,'.'), strlen($filename)-1); // Get the extension from the filename.

if($auth == "1") {   

$id = "0";
while(is_file($filename))
{
  $id++;
  $filename = $id.'_'.$filename;

}

   // Check if the filetype is allowed, if not DIE and inform the user.
   if(!in_array($ext,$allowed_filetypes)){
      die('The file you attempted to upload is not allowed.');
}
   // Now check the filesize, if it is too large then DIE and inform the user.
   if(filesize($_FILES['userfile']['tmp_name']) > $max_filesize){
      die('The file you attempted to upload is too large.');
}
   // Check if we can upload to the specified path, if not DIE and inform the user.
   if(!is_writable($upload_path)){
      die('You cannot upload to the specified directory, please CHMOD it to 777.');
}
   // Upload the file to your specified path.
   if(move_uploaded_file($_FILES['userfile']['tmp_name'],$upload_path . $filename)) {

   echo "Your submission was successfull<br />";
   echo $upload_path . $filename;

   
   } else {
   
   echo "There was a problem";



}
}
?>

Use file_exists(), not is_file().
