$_FILES problem

[Iced Milk Tea]

I am trying to program a upload system.

The following code work very fine,

$file_name = $_FILES['uploadFile'. $x]['name'];
$size = filesize($file_ name);
$type = mime_content_ty pe($file_name);

However, when I change to

$file_name = $_FILES['uploadFile'. $x]['name'];
$size = $_FILES['uploadFile'. $x]['size'];
$type = $_FILES['uploadFile'. $x]['type'];

The program fail to give me any result.

Is there any problem happan in my code?

Thanks in advance for your advice.

hi

don't rely on $_FILES['name']['type'] as php relies on the browser to
supply this.
here's a function from the contrib notes:

if (!function_exis ts('mime_conten t_type')) {
function mime_content_ty pe($f) {
$f = escapeshellarg( $f);
return trim( `file -bi $f` );
}
}

have you moved the uploaded file yet?
the path to the actual file is being kept in $_FILES['name']['tmp_name']
so your 1st piece of code shouldn't work.

Thanks a lot for your help!

I think bcoz' I haven't moved the file so problem arise.

But why does $_FILES['userfile']['name'] is working?

I don't really know, maybe you've got a file on the server with the same
name?
