ID: 30924 User updated by: himself at zhwau dot net Reported By: himself at zhwau dot net -Status: Feedback +Status: Open 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.

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. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=30924&edit=1
