[SOLVED] Generate Random File Name on Upload

[atticus]

The file is uploading to the server, however in order to keep files from being overwritten I want to generate a random file name.  It is uploading to the file, however it is not generating the random name.

 

<?php
include("config.php");
  if(isset($_POST['submit']))

  {
  $uploadDir = 'upload/';
  $id = mysql_escape_string($_POST['id']);
  $fileName = $_FILES['userfile']['name'];
$tmpName = $_FILES['userfile']['tmp_name'];
$fileSize = $_FILES['userfile']['size'];
$fileType = $_FILES['userfile']['type'];

// get the file extension first
$ext = substr(strrchr($fileName, "."), 1); 

// generate the random file name
$randName = md5(rand() * time());

$filePath = $uploadDir . $fileName;

$result = move_uploaded_file($tmpName, $filePath);
if (!$result) {
echo "Error uploading file";
exit;
}

you have just written your file path line wrong it needs to be like this

 

$filePath = $uploadDir . $randName . '.' . $ext;
