I'm trying to debug an issue with a WordPress 3.5.1 where I cannot upload media via HTTP at all; the media uploader simply says "HTTP error" and fails. To diagnose what's going on, I decided to write (i.e. copy from w3schools) a really basic PHP file uploader to see if there's something weird going on behind the scenes. But for some reason, the $_FILE structure doesn't contain any information at all, even in the most basic of examples:

file.php :

<html>
<body>

<form action="upload.php" method="post" enctype="multipart/form-data">
  <label for="file">Filename:</label>
  <input type="file" name="file" id="file"><br>
  <input type="submit" name="submit" value="Submit">
</form>

</body>
</html>

upload.php :

<?php
if ($_FILES["file"]["error"] > 0)
{
  echo "Error: " . $_FILES["file"]["error"] . "<br>";
}
else
{
  echo "Upload: " . $_FILES["file"]["name"] . "<br>";
  echo "Type: " . $_FILES["file"]["type"] . "<br>";
  echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
  echo "Stored in: " . $_FILES["file"]["tmp_name"];
}
?>

In every browser I've tried, with every file I've tried, this just outputs:

Upload: 
Type: 
Size: 0 kB
Stored in:

and printing $_FILES shows that it is just an empty array.

I'm using PHP-5 on shared hosting (lunarpages), but the php.ini file has file_uploads on and the size of the files I tried is nowhere even close to the upload_max_filesize. I am ready to throw my laptop against a wall, so any help would save me a couple thousand dollars.

Whats the output, when you discard the if/else and just put <?php error_reporting_(E_A‌​LL); ini_set('display_err‌​ors', true); print_r($_FILES); ?> in the script? – DanFromGermany Jun 13 '13 at 21:28

Do you have write permissions to that folder? – Don Rhummy Jun 13 '13 at 21:31

what has w3fools.com to do with this question? – DanFromGermany Jun 13 '13 at 21:32

I copied exactly your code and it worked for me. Change the permission of everything to 777 for directories and 666 for files – DanFromGermany Jun 13 '13 at 21:40

If it's hosted by Lunar, I'd give them a call. They might have set up some unusual settings. BTW, if php.ini or .htaccess or any of the relevant ".conf" files don't allow it, those ini_set commands won't do anything. – Don Rhummy Jun 13 '13 at 22:04

<html>
<body>

<form action="upload.php" method="post" enctype="multipart/form-data">
  <label for="file">Filename:</label>
  <input type="file" name="file" id="file"><br>
  <input type="submit" name="submit" value="Submit">
</form>

<?php
phpinfo();
?>

</body>
</html>

This worked for me, $_FILES was not empty, using a common Debian installation, PHP 5.2; try to adjust the permissions of your files and direcotires to 777

I tried adjusting the permissions to 777 for everything, but that resulted in an Internal Server Error when loading either php file. – Maxwell Collard Jun 13 '13 at 21:57
    
Only thing I can help you is, take a deep look into phpinfo(); and your hosters settings. >.< – DanFromGermany Jun 13 '13 at 22:22

I had a similar issue once with a shared host. Turned out that I had no tmp directory set, therefore nothing was being uploaded. Check with your host that your php.ini is set up correctly and that a tmp directory exists for uploads and that you have write permissions for it.

$target="Your Path";
if(move_uploaded_file($_FILES['file']['tmp_name'], $target)) 
{
  echo "Upload: " . $_FILES["file"]["name"] . "<br>";
  echo "Type: " . $_FILES["file"]["type"] . "<br>";
  echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
  echo "Stored in: " . $_FILES["file"]["tmp_name"]; 
} 
else 
{ 
  echo "Unable to move temp file to target.";
}

If it is not yet too late, you should check your apache logs. The most probably cause is that the apache - and so your php interpreter - has no permission to your predefined upload directory.
