$_FILES is not empty but move_uploaded_file returns false

Question

I have a problem. Since hours I try to get a upload script working. I also read some other questions on stackoverflow but nothing helped. The webspace allows file_upload and the size of the file is not too large. The directory where to move the downloads exists, too. My html code is:

Upload: <input type="file" name="file">

And my PHP code is:

if ($_FILES['file']['error'] == 0) {
    $tmp_name = $_FILES["file"]["tmp_name"];
    $name_file = $_FILES["file"]["name"];
    move_uploaded_file($tmp_name, "upload/" . $name_file);
}

I echoed $_FILES and the file was in there and there was no error. Everytime I try to upload the file (I also tried to upload other files and file types) move_uploaded_file returned false.

EDIT: The folder is writeable now.

Yes the folder exists and the permissions are 755. I think that these are the right permissions. — bw2801, Mar 30 '13 at 18:49
you can add this before move_uploaded_file(): `if(!is_writable("upload") || !is_dir("upload")){ echo "error in dir"; }` — , Mar 30 '13 at 18:52
if you check [here](http://php.net/manual/en/function.move-uploaded-file.php) you will read that **If filename is a valid upload file, but cannot be moved for some reason, no action will occur, and move_uploaded_file() will return FALSE**. Just check your uploading folder permissions. — alexcasalboni, Mar 30 '13 at 18:52
Double check that it is writable by running `is_writable()` http://www.php.net/manual/en/function.is-writable.php — Luke Shaheen, Mar 30 '13 at 18:53
`is_writable()` return false and `is_dir()` returns true. The dir-permissions are 755. Is this wrong? — bw2801, Mar 30 '13 at 18:57
Okay, I updated the permissions but the file does not get moved... — bw2801, Mar 30 '13 at 19:00
What type of file are you uploading? Have you tried uploading to a different directory, or `move_uploaded_file($tmp_name, "upload/ahardcodedfilename.yourext);` where `yourext` is the extension of the file you are uploading? Just trying to help you identify the issue. — Luke Shaheen, Mar 30 '13 at 20:01
Nope. Another directory does not work (it is writable) and a hardcoded filename does not work, too. — bw2801, Mar 30 '13 at 22:36

Okay, I solved my problem. I enabled error_resporting() and because any reason the permissions weren't set. Now they are 777 and I can move the files.

Folder upload will not writable by others by setting permission 755. You may set permission atleast 666 through chmod command or better set ownership for upload folder for apache user.

I setup it On Ubuntu like that

sudo chown www-data:www-data upload

Set the folder permissions on upload to 666. This should ensure that the directory is correctly writeable.

Hope this may help someone.

I met the same problem, my $_FILES['file']['tmp_name'] has proper returns while move_uploaded_file($_FILES['file']['tmp_name'],$destination_dir) returns nothing. So I ran this check:

if(!is_writable($destination_dir)){ echo "error in dir"; }

and got the message "error in dir". Even my $destination_dir in move_uploaded_file has been set to 777. After spending a long time searching, I found this answer. So these two commands solved my problem:

sudo chmod -R 777 Ad_images/
sudo chcon -R -t httpd_sys_rw_content_t Ad_images/

Now the is_writable($destination_dir) returns 1 and the uploading is successful.

TL;DR: Make sure your destination directory is writable for php.

$_FILES is not empty but move_uploaded_file returns false
