[support] Printing "0" when a db query returns nothing

[Neil Coghlan]

this has the same problem as the first solution suggested...people with 5 downloads are now shown as having 50. People without any downloads correctly have 0.

    I am trying to print the number of downloads a user's attachments have produced and am 95% there. I just don't know how to print zero if the SUM returns nothing.

    here's what I have so far (with download count module installed which creates file_downloads table)

    <?php
    $query= "SELECT SUM(count) AS DownloadCount
    FROM upload
    JOIN files 
    ON upload.fid = files.fid
    JOIN file_downloads
    ON files.filepath = CONCAT( 'sites/default/files/', file_downloads.filename )
    WHERE (files.uid = $account->uid)";
    $results = db_query($query);
    while($output = db_fetch_object($results)){
    print $output->DownloadCount;


  print (is_int($output->DownloadCount) && (int) $output->DownloadCount > 0) ? $output->DownloadCount : NICE_FAT_ZERO;
   

    }
    ?>

    works perfectly for those whose content have created downloads. For those who haven't, the result is a blank space. How can I print a nice fat "0"??
