YUI Uploader ... Can't get it to upload

n00b0101 used Ask the Experts™
Trying to implement the example of the YUI uploader, but even though it says the file has been successfully uploaded, it's nowhere to be found... I'm basically using the single file upload example as is, except that I changed uploader.upload to uploader.upload(fileID, "/up.php")...  

When I return the $_POST and $_FILES contents, I get this:

    [Filename] => aa024380_uc.jpg
    [var2] => var2 default value
    [var1] => var1 default value
    [Upload] => Submit Query
    [Filedata] => Array
            [name] => aa024380_uc.jpg
            [type] =>
            [tmp_name] =>
            [error] => 6
            [size] => 0


So, the tmp_name is blank, which I was thinking maybe was the issue, although I can't figure out why...  

The scripts that I'm including (maybe I left something out?) are as follows:

<script type="text/javascript" src="/js/yahoo-min.js"></script>
<script type="text/javascript" src="/js/utilities.js"></script>
<script type="text/javascript" src="/js/yahoo-dom-event.js"></script>
<script type="text/javascript" src="/js/element-min.js"></script>
<script type="text/javascript" src="/js/uploader.js"></script>

The PHP script looks like this:

(I tried with $file['tmp_name'], but since it's blank...)

header('Content-type: text/json');
	$file = $_FILES['Filedata'];
	$name = $file['name'];
	move_uploaded_file($file['name'], "/images/".$file['name']);

I see a couple of problems in the script:

Line 12 has move_uploaded_file($file['name'], "/images/".$file['name']);
2 problems here.  You need to use $file['tmp_name'] for the first variable here and the second variable has to be an absolute value not a relative one ("/home/httpdocs/images/".$file['name']) otherwise the file won't end up anywhere.

Make sure that your tmp directory is writable by PHP.  You can check this using phpinfo() and finding your tmp path and making sure that the permissions are correct.  It might not be.  I would also check to see if you have any open_basedir() (restricts the sites ability to see only specific directories) restrictions also.

I would also change line 12 to the code example below (This checks to see if the file is an uploaded file as far as PHP is concerned and if it can be moved:
//12. move_uploaded_file($file['name'], "/images/".$file['name']);
if (is_uploaded_file($file['tmp_name']) ) {
    if( move_uploaded_file($file['tmp_name'], "/images/".$file['name']) ) {
        echo 'There was a problem moving the file';
    } else {
        echo 'File was not uploaded';
} else {
    echo 'File was not uploaded';

Thanks for the response...

I changed it to an absolute path and put your if statement in there.  It returns false for is_uploaded_file.  What does that mean?  
That means that your temp directory is most likely not writable by PHP.  Double check the location of your temp directory and make sure it is writable.


Thanks!  Your smartness is appreciated :)
