// first let's set some variables

// make a note of the current working directory relative to root.
$directory_self = str_replace(basename($_SERVER['PHP_SELF']), '', $_SERVER['PHP_SELF']);

// make a note of the location of the upload handler script
$uploadHandler = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'upload.processor.php';

// set a max file size for the html upload form
$max_file_size = 30000000; // size in bytes

        </p>
    
    </form>
    
    
    </body>

</html>
<body>
</body>

my upload script...



<?php
include('session.php');
?>
<?php
session_start();

$userid = $_GET['user_id'];
// filename: upload.processor.php

// first let's set some variables

// make a note of the current working directory, relative to root.
$directory_self = str_replace(basename($_SERVER['PHP_SELF']), '', $_SERVER['PHP_SELF']);

// make a note of the directory that will recieve the uploaded file
$uploadsDirectory = $_SERVER['DOCUMENT_ROOT'] . $directory_self . 'profilepic/';

// make a note of the location of the upload form in case we need it
$uploadForm = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'upload.form.php';

// make a note of the location of the success page
$uploadSuccess = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'upload.success.php';

// fieldname used within the file <input> of the HTML form
$fieldname = 'file';

// Now let's deal with the upload

// possible PHP upload errors
$errors = array(1 => 'php.ini max file size exceeded',
                2 => 'html form max file size exceeded',
                3 => 'file upload was only partial',
                4 => 'no file was attached');

// check the upload form was actually submitted else print the form
isset($_POST['submit'])
    or error('the upload form is neaded', $uploadForm);

// check for PHP's built-in uploading errors
($_FILES[$fieldname]['error'] == 0)
    or error($errors[$_FILES[$fieldname]['error']], $uploadForm);
   
// check that the file we are working on really was the subject of an HTTP upload
@is_uploaded_file($_FILES[$fieldname]['tmp_name'])
    or error('not an HTTP upload', $uploadForm);
   
// validation... since this is an image upload script we should run a check  
// to make sure the uploaded file is in fact an image. Here is a simple check:
// getimagesize() returns false if the file tested is not an image.
@getimagesize($_FILES[$fieldname]['tmp_name'])
    or error('only image uploads are allowed', $uploadForm);
   
// make a unique filename for the uploaded file and check it is not already
// taken... if it is already taken keep trying until we find a vacant one
// sample filename: 1140732936-filename.jpg
$now = time();
while(file_exists($uploadFilename = $uploadsDirectory.$now.'-'.$_FILES[$fieldname]['name']))
{
    $now++;
}

// now let's move the file to its final location and allocate the new filename to it
@move_uploaded_file($_FILES[$fieldname]['tmp_name'], $uploadFilename)
    or error('receiving directory insuffiecient permission', $uploadForm);
   
// If you got this far, everything has worked and the file has been successfully saved.
// We are now going to redirect the client to a success page.
mysql_connect("localhost", "", "") or die(mysql_error());
mysql_select_db("") or die(mysql_error());
$profile_pic = "http://www.notpad.co.uk/profilepic/" . $uploadFilename;


$sql = ("UPDATE members SET profile_pic='$profile_pic' WHERE username='".$_SESSION['myusername']."'");
mysql_query($sql)or die(mysql_error()); 

header('Location: ' . $uploadSuccess);


// The following function is an error handler which is used
// to output an HTML error page if the file upload fails
function error($error, $location, $seconds = 5)
{
    header("Refresh: $seconds; URL=\"$location\"");
    echo '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"'."\n".

im having a problem with this bit of the upload script


// make a unique filename for the uploaded file and check it is not already
// taken... if it is already taken keep trying until we find a vacant one
// sample filename: 1140732936-filename.jpg
$now = time();
while(file_exists($uploadFilename = $uploadsDirectory.$now.'-'.$_FILES[$fieldname]['name']))
{




if i upload a pic called nick it will rename it 123-nick its storing nick in the database when the file is called 123-nick

can any 1 help ? ether make it store the new name of the file after it changes or stop it from changing the file name i guess the first 1 would be better store the new file name the sql is there



$sql = ("UPDATE members SET profile_pic='$profile_pic' WHERE username='".$_SESSION['myusername']."'");
mysql_query($sql)or die(mysql_error());
