Upload file that does not exist

[damezumari]

I have a form:

<form method="post" action="res_add aresource.php" name="frm1"
enctype="multip art/form-data" onsubmit="retur n checkFields();" >

with a file object:

<input name="localfile " id="localfile" type="file" size="68">

to upload a file.

I click the Browse button and select a file on my hard disk. Then I
delete or rename the file on my hard disk. When I then submit the
form

$uploaded = move_uploaded_f ile($_FILES['localfile']['tmp_name'],
$uploadfile);

returns true and $_FILES['userfile']['error'] does not return an error
(it returns the empty string which I guess means 0).

The only way to detect something fishy is going on is looking at
$_FILES['localfile']['size'] that returns 0.

Is this the way things are supposed to be? I would want $uploaded to
be false.

Well, the UA should issue the warning/block on a submit (Opera does BTW,
with a nice inline explanation next to the input element, FF & MSIE
don't). There's no way you can know it's not supposed to be an empty file,
which it could be. Empty files are used quite regularly for genuine
purposes.
