PHP - Rename Uploaded File How?

Hi everyone, im a newbie and have written this script, has taken me a day to get here.
The form inserts data into the database, uploads a file and sends an email.
All this works fine, what i am trying to do is rename the file to the id of the record and check to make sure it is a pdf.
I would really appreciate any help. I've tried and tried and just cant get it to work.

<?php
switch ($_REQUEST['action']) {
case 'recruit':
foreach($_POST as $key=>$value){
$$key = $value;
}
if ((!$name) || (!$email) || (!$phone)) {
$error_msg = 'Fields marked<span class="gold"> * </span>are required to submit the form';
}elseif (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email)) { 
    $error_msg = 'Invalid email address'; 
}
echo "$error_msg","<br><br>";
if ($error_msg == ''){

$date=date("d/m/y", time());
$add="recruitment/".$_FILES[userfile][name];
$cleaned = stripit($add);
    $add2 = $cleaned;

   if(move_uploaded_file ($_FILES[userfile][tmp_name], $add2));

Hey guys, total newb when it comes to php. any help here would be much apreciated,

what i am trying to achieve is to allow a person to upload a jpg image that he wants displayed on a dynamic flash site, but seeing as the flash is looking for xx.jpg, is it possible that any jpg file he uploads , say its called golf.jpg, is automatically uploaded/renamed to xx.jpg ? so i dont have to get him to rename the files before uploading.

i attempted to understand a short tutorial on doing this but failed, here is what code i used. ( i added that rename line, looking at it now sorta seems like a really lame attempt lol )

Code: [Select]
<?php 
 $target = "upload/"; 
 $target = $target . basename( $_FILES['uploaded']['name']) ; 
 $ok=1; 
 
rename ("*.jpg", "xx.jpg");

 //This is our size condition 
 if ($uploaded_size > 350000) 
 { 
 echo "Your file is too large.<br>"; 
 $ok=0; 
 } 
 
 //This is our limit file type condition 
 if ($uploaded_type =="text/php") 
 { 
 echo "No PHP files<br>"; 
 $ok=0; 
 } 
 
 //Here we check that $ok was not set to 0 by an error 
 if ($ok==0) 
 { 
 Echo "Sorry your file was not uploaded"; 
 } 
 
 //If everything is ok we try to upload it 
 else 
 { 
 if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)) 
 { 
 echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded"; 
 } 
 else 
 { 
 echo "Sorry, there was a problem uploading your file."; 
 } 
 } 
 ?>
 
<body>
<form enctype="multipart/form-data" action="upload.php" method="POST">
 Please choose a file: <input name="uploaded" type="file" /><br />
 <input type="submit" value="Upload" />
 </form>

cheers

i coded this and it works previously but now its not working. its say: syntax error, unexpected $end.

below in the code which rename the files

<?php

session_start();
if(!isset($_SESSION['myusername'])){
header("location:index.php");
}

else {

// get the new and prev file name
$newn = $_POST[ 'filename' ];
$prevn = $_POST[ 'filepg' ];

// get user directory path
$dirpath = "u/"  . ($_SESSION['myusername']) . "/"; 

// new filename
$newn = "$dirpath$newn";

//old filename
$prevn = "$dirpath$prevn";

// rename to file
rename("$prevn", "$newn");

echo "<center><br><br><h2>";
echo "The file $prevn has been renamed to $newn!</h2></center>";
header( 'refresh: 2; url=files.php' );
?>

if (isset($_POST['register']) && $_POST['register'])
{
$update = mysql_query("UPDATE agents SET credit= credit-1 WHERE username='$username'");
//image1
$nameone=$_FILES['myfileone']['name'];
if ($nameone)

{
$dst_filename = resize_upload_image($_FILES['myfileone'], "images/");
if ($dst_filename !== false) {
extract($dst_filename);
$image1 = mysql_query ("UPDATE img SET image1='$img_filename', thumb1='$thumb_filename'");
}
}


function resize_image($srcfilename, $dstfilename, $new_width, $new_height)
{
$ext = strtoupper(pathinfo($srcfilename, PATHINFO_EXTENSION)); 
// JPEG image 

if(is_file($srcfilename) && ($ext == "JPG" OR $ext == "JPEG")) 
{ 
// Get src dimensions
list($width, $height) = getimagesize($srcfilename);

// Resample
$image_p = imagecreatetruecolor($new_width, $new_height);
$image = imagecreatefromjpeg($srcfilename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

// Output
imagejpeg($image_p, $dstfilename, 100);
return TRUE;
} 
// PNG image 
elseif(is_file($srcfilename) && $ext == "PNG") 
{ 
// Get src dimensions
list($width, $height) = getimagesize($srcfilename);

// Resample
$image_p = imagecreatetruecolor($new_width, $new_height);
$image = imagecreatefrompng($srcfilename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

// Output
imagepng($image_p, $dstfilename, 0);
return TRUE;
}
return false;
}

function resize_upload_image($file, $path)
{
global $standard_width, $standard_height;
global $thumb_width, $thumb_height;

$img_name= $file['name'];
$tmp_name= $file['tmp_name'];
if ($img_name)
{
if (substr($path, strlen($path)-1) != "/") {
$path .= "/";
}

$original_img_name = $path."tmp-".$img_name;
move_uploaded_file($tmp_name, $original_img_name);
$img_location = $path.$img_name;
$thumb_location = $path."thumb-".$img_name;

if (resize_image($original_img_name, $img_location, $standard_width, $standard_height) === FALSE) {
unlink($original_img_name);
return false;
}
if (resize_image($original_img_name, $thumb_location, $thumb_width, $thumb_height) === FALSE) {
unlink($original_img_name);
return false;
}
unlink($original_img_name);
return array("img_filename"=>$img_location, "thumb_filename"=>$thumb_location);
}
return false;
}




sp this is a time id which could be added


$image_name=time().'.'.$extension;

$filename = "img/". $image_name;

$filename1 = "img/small_". $image_name;

i have the following code:
$filename = $this->getMsisdn().".png";
if (!file_exists(sfConfig::get('sf_upload_dir') . '/rainbowcode/images/profilepics/'.$filename))
{
     $filename = "Rainbow-code-1_blck.jpg";
     //rename it to msisdn
               
     $source = imagecreatefromjpeg($filename);
}

i JUST want to rename "Rainbow-code-1_blck.jpg" to $this->getMsisdn().".jpg" ??
is this possible?? i want to have the SAME picture but it has a different name

please help?
