is_uploaded_file woes

[RussWright]

Hi all

I'm having some problems with this command
it seems to randomly reject files. Here is my code:

//security test for malicious file
if (!is_uploaded_file($txtImageFile))
{
echo "possible Malicious file upload attack. This will be logged..";
fn_LogAction();
exit;
}

I can seem to find no reason why sometimes it rejects files. I am working mostly with jpeg files and they are all about the same size.

Any ideas?

Another possibility to check whether a file has been uploaded is:

if(!$userfile_size) {
   echo "Either you did not upload any file, or you uploaded an empty file!";
}

if(!$_FILES['userfile']['size']) {
   echo "Either you did not upload any file, or you uploaded an empty file!";
}

but I think your check is correct.

I think the connection between clients and server is not the best on. If all clients have the same problems, ask your provider if he can determine if your server connection to the internet is ok, (timeouts, bandwith, ...).
