Bug Type: Filesystem function related
Operating System: Windows XP
PHP Version: 5.0.2
New Comment:
The system the command was run on has the following configuration:
- Athlon XP 2000+ 512MB RAM
- Windows XP SP2
- Apache 2.0.52
- PHP 5.0.2 (running as Apache module, php5_module)
The input form that sends the file via POST is as follows:
<FORM enctype="multipart/form-data" action="vnos.php" method="post">
<INPUT type="file" name="slika" size=50>
<INPUT type="submit" value="Poslji">
</FORM>
The receiving page (vnos.php) contains the following code:
<?php
$ime = $_FILES['slika']['name'];
$tmp = $_FILES['slika']['tmp_name'];
if (move_uploaded_file($tmp, $ime)) {
echo '<H2>File uploaded!';
}
else {
echo '<H2>Error during transfer.</H2>';
}
?>
If you submit the file in the first file, move_uploaded_file in the
second file (vnos.php) returns TRUE, but the file isn't moved. Also,
the vardump on $_FILES does return the appropriate information about
the contents and properties of the file submitted via POST.
Using Firefox, if you reload the page and acknowledge resending the
POSTDATA, then the script executes exactly the same, only this time,
the file gets moved. I haven't tested subsequent reloads, but I'm
assuming the file gets overwritten.
In short - the function 'move_uploaded_file' does NOT move the file on
the first run, but resubmitting the POST data makes the function work
properly.
The temp file directory resides in one of the subdirs on the root of
the webserver, and the webserver has full access to any file or dir in
the document root.

Description:
------------
When trying to POST upload a file with the proper <FORM> tag, including
the proper enctype and all (but without size restriction with
MAX_FILE_SIZE as in manual example), the receiving script defined in
ACTION results in move_uploaded_file() returning TRUE even though the
file wasn't moved at all.
Odd things happen when you try reloading the ACTION target page which
makes Firefox repost the data - the second time around, the PHP script
moves the file, even though it is assigned a different temp file name.
Then everything works fine.
Could this be the result of a write-behind process for the filesystem
which makes move_uploaded_file() return true even if it didn't move the
actual file?
Reproduce code:
---------------
<?php
// The receiving script
$ime = $_FILES['slika']['name'];
if (move_uploaded_file($_FILES['slika']['tmp_name'], $ime)) {
// Here i execute the code responsible for handling the file
}
else {
// Report that the upload failed
}
?>
Expected result:
----------------
Should execute the 'ELSE' part of the sentence, since the
move_upload_file() should return true in the case of a failed file move
- unless it only detects whether or not the tmp_name file exists.
Actual result:
--------------
First time around, the move_uploaded_file() returns true (meaning the
temp file exists) but the file isn't moved to $ime (i.e. the same dir
where the script is executed).
If you reload the page (and repost the same data), the tmp_name changes
while all stays the same and the file is successfully moved.
