PHP - File Upload Fail

Question

I don't understand why this is not working. It should be very easy.

upload.php :

$uploaddir = '/usr/share/nginx/www/pitfax/upload/'; 
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);

echo "<p>";

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {   
    echo "File is valid, and was successfully uploaded.\n"; 
} 
else {
    echo "Upload failed"; 
}

echo "</p>"; 
echo '<pre>'; 
echo 'Here is some more debugging info:'; 
print_r($_FILES); print "</pre>";

form page:

<form enctype="multipart/form-data" action="upload.php" method="POST">
    <input type="hidden" name="MAX_FILE_SIZE" value="10000000" />
    Send this file: <input name="userfile" type="file" />
    <input type="submit" value="Send File" />
</form>

the error output is :

Upload failed

Here is some more debugging info:Array (
    [userfile] => Array
        (
            [name] => test.pdf
            [type] => application/pdf
            [tmp_name] => /tmp/phptM0p4w
            [error] => 0
            [size] => 1287464
        )

)

Webserver : NginX
Permissions for upload.php : 644
Permissions for upload directory : 755
Working in SSH with root user.
Edit : upload_max_filesize = 2M
Edit : post_max_size = 8M

Another thing! After upload is done, I want to get absolute path of the uploaded file. (ex:/usr/share/nginx/www/pitfax/upload/test.pdf)

Are you confident that basename() isn't effecting it? In your debug output perhaps you can echo $uploadfile; and just double check that its not just trying to upload as a directory. — Luke Pittman

How can $uploadfile be only upload/test.pdf? There should be a full path there! If there is no upload directory at the place where the script is executing, that would explain while move_uploaded_file fails. — Konrad Neuwirth

If the value of $uploadfile is upload/test.pdf but you want it to be /usr/share/nginx/www/pitfax/upload/test.pdf than I would suspect that would be your problem.

Try this code:

$uploadfile = '/usr/share/nginx/www/pitfax/upload/' . $_FILES['userfile']['name'];

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
  echo "File is valid, and was successfully uploaded.\n";
} else {
  print_r ($_FILES);
}

EDIT: Code formatting.

Ok the output of echo $uploadfile; is as it should be. But the upload still fails. output is

Array ( [userfile] => Array ( [name] => test.pdf [type] => application/pdf [tmp_name] => /tmp/phpbGRbCg [error] => 0 [size] => 1287464 ) )

When trying to help someone else with a problem I was told this isn't a debugging service. So I'm afraid at this point there isn't much I can do. I would check log files (apache error logs) for hints, echo all of your variables, try with fixed file names, etc...

I changed permission of upload directory to 777 again and suddenly the upload worked! Thanks!
