[RESOLVED] Image Upload and Rename

[blueleafprint]

I am trying to rename a file that is being uploaded from a form.

The code I am using to upload the file is

<? 
// this starts the session
session_start();

// this pulls input variables from the session form 
$_SESSION['id']	= $_POST['id'];
?>

<?php
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg")
|| ($_FILES["file"]["type"] == "image/bmp")
|| ($_FILES["file"]["type"] == "image/tiff")
))
	{
	move_uploaded_file($_FILES['file']['tmp_name'], "files/" . $_FILES['file']['name']);
	echo "Your image has been uploaded";
	}
else
	{
	echo "Invalid file";
	}
?>

But I need to be able to rename the file to the 'id' pulled in form the form.

Thanks,
George

i think its just

$file = $_FILES['userfile']['name'];
$ext 		= substr($file, strpos($file,'.'), strlen($file)-1);
//...
move_uploaded_file($_FILES['file']['tmp_name'], "files/" . $newfilename . $ext);

Also note that the 'type' index of the FILES array is provided by the browser; therefore, just because it's value may be "image/jpeg" there's no guarantee that the file uploaded was actually a JPEG image (or an image at all, for that matter).

Thanks for the response, but I can't seem to get it to work. 😕

The error I get is...

Warning: move_uploaded_file(files/) [function.move-uploaded-file]: failed to open stream: Is a directory in /home/sites/creativbloc.co.uk/public_html/site/uploadfile.php on line 16

Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/tmp/phphEYmyf' to 'files/' in /home/sites/creativbloc.co.uk/public_html/site/uploadfile.php on line 16
Your image has been uploaded

I am using the code...

<?
$newfilename = $_POST['id'];
?>

<?php
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg")
|| ($_FILES["file"]["type"] == "image/bmp")
|| ($_FILES["file"]["type"] == "image/tiff")
))
    {
    $file = $_FILES['userfile']['name'];
	$ext = substr($file, strpos($file,'.'), strlen($file)-1);
	//...
	move_uploaded_file($_FILES['file']['tmp_name'], "files/" . $newfilename . $ext);     

	echo "Your image has been uploaded";
    }
else
    {
    echo "Invalid file";
    }
?> 

Thanks George
