$_FILES['userfile']['tmp_name'] is empty!

I have had a file upload on my site for about a year, and all of a sudden it stopped working. I identified the problem is that the tmp_name is empty. I have way more than enough space on the server, so that isn't the problem.

if($_FILES['userfile']['name'] != "") {
$allowed_filetypes = array('.gif','.jpg','.jpeg','.png','.JPG','.GIF','.JPEG','.PNG');
$max_filesize = 2097152; // (currently 2.0MB).
$upload_path = './bgimages/';

$filename = $_FILES['userfile']['name'];
$ext = substr($filename, strpos($filename,'.'), strlen($filename)-1);

list($width, $height, $type, $attr) = getimagesize($_FILES['userfile']['tmp_name'] );
if ($width > 1920 || $height > 1200)
$error = "Maximum width and height exceeded. The maximum size is 190x150.";

if(!in_array($ext,$allowed_filetypes))
$error = "The file you attempted to upload is not allowed.";

if(filesize($_FILES['userfile']['tmp_name']) > $max_filesize)
$error = "The file you attempted to upload is too large. 2MB maximum.";

if(!is_writable($upload_path))
$error = "You cannot upload to the specified directory, please CHMOD it to 777.";

if (empty($error)) {
$filename = $user_id . $_FILES['userfile']['name'];
if(move_uploaded_file($_FILES['userfile']['tmp_name'],$upload_path . $filename))
$msg = "Your file upload was successful.";
else
$error = "There was an error during the file upload. Please try again later or contact support.";
}

Running this gives me the error: Warning: getimagesize() [function.getimagesize]: Filename cannot be empty in /patchto/public_html/settings/createtheme.php on line 68

I also have the correct multipart/form-data enctype on the form.

Any ideas what would cause it to suddenly stop working? I'm thinking it has to be something with the server?

What are you actually getting? Add the following debugging code -
echo "<pre>";
echo "POST:";
print_r($_POST);
echo "FILES:";
print_r($_FILES);
echo "</pre>";

POST:Array
(
[theme_name] => test
[category] => Education
[description] =>
[yt_link] =>
[logo] => images/logo.png
[searchbar] => 1
[bg_image] =>
[MAX_FILE_SIZE] => 524288
[bg_color] =>
[link_color] =>
[menu_border] =>
[menu_hover] =>
[menu_bg] =>
[privacy] => 0
[style] => 1
[CreateTheme] => Create theme
)
FILES:Array
(
[userfile] => Array
(
[name] => amy.jpg
[type] =>
[tmp_name] =>
[error] => 2
[size] => 0
)

)

Well that is strange. :confused:

A) Real code always checks for errors before blindly accessing data that might not exist,
B) Here the link to the documentation that tells you what that error code means - http://www.php.net/manual/en/features.file-upload.errors.php

What a silly mistake on my part. I was using MAX_FILE_SIZE as a hidden input, but it was a lower value than the php check, duh!

Thanks for the help! :thumbsup:
