Hi,
It is not working because register globals (http://php.net/register_globals) are set to off by default since PHP version 4.2.0.
I suppose that your version of PHP is newer and (the article is from 2002) their is most probably older ;)

in order to make it work, you'll have to explicitly take your variables from the POST array:

instead of:

global $strDesc;
global $fileUpload;
global $fileUpload_name;
global $fileUpload_size;
global $fileUpload_type;


write(if your HTML is the same as in the article and your method is set to post):

$strDesc = $_POST['strDesc'];
$fileUpload = $_FILE['fileUpload'];
$fileUpload_name = $_FILE['fileUpload']['name'];
$fileUpload_type = $_FILE['fileUpload']['type'];
$fileUpload_size = $_FILE['fileUpload']['size'];


not sure if it will work, i did not test it
good luck

yes, your PHP version might be lower than 4.1.0.
read this:
http://us3.php.net/manual/en/reserved.variables.php#reserved.variables.files

You need to check to make sure the file was actually opened. I can nearly guarantee you that you're passing an invalid filename, or trying to access a file without the correct permissions, which is causing fopen() to fail. Put everything after the line with fopen() in an if statement that looks like this:

//Other code up here
$fileHandle = fopen($fileUpload, "r");
if ($fileHandle)
{
//REST OF YOUR CODE HERE
}
else
{
echo "Was not able to open file";
}


If "Was not able to open file" prints out, then you know that either you've got a filename wrong, you're handling a file upload wrong, or you do not have the correct permissions set. I would need to see the upload script as well as the rest of the scripts to know which though. But in the interim, you can start looking there. (I bet you didn't correctly set the permissions of the file, or forgot to move it to a non-temporary directory).

PS:
I think she's too polite to mention it, but lilcrazyfuzzy is not a "bro" as it were...
