problems with upload file

[Anon]

i've tried all codes founded here and in the manual of PHP, but no one works until now.

my code (the latest) is below:

<?php

// up.php (it should upload the files)

$destination="../files/$userfile_name";

if (isset($submit))
{

$file_name = $HTTP_POST_FILES['userfile']['name'];
move_uploaded_file($userfile, $file_name);

}

?>

when a submit this, an error message occurs like this:

Warning: Unable to create 'camera_01.jpg': Permission denied in /www/my_user_name/public_html/tests/up.php on line 46

Warning: Unable to move '/tmp/phpMftyyb' to 'camera_01.jpg' in /www/my_user_name/public_html/tests/up.php on line 46

my line 46 is below:

move_uploaded_file($userfile, $file_name);

someone please, HELP ME!!! I have to ask permission to my server? What type?...

Thank you.

Look at permission for directory where you want to put your files. Do you have ftp access to server? Try to turn on "write access" on your directory for "group" or for "others".

Yes, i have FTP access to the server. The is directory already created, but don't work...

Where can i change the permissions? I will ask to the host?

Thank you.
