Not so far... here's the code:
//...
// 1. the csv for importing into the Office db
$filename = $writeorderfile.$mcnum.'.csv';
if (!$handle = fopen($filename, 'w')) {
echo "Cannot open file ($filename)";
exit;
}
if (fwrite($handle, $outcsv) === FALSE) {
echo "Cannot write CSV data to file ($filename)";
exit;
}
fclose($handle);
if (chown($filename,"orders")) {
echo "chowned() $filename";
}
else
{
echo "Couldn't chown $filename\n\n";
}
if ( chmod($filename,octdec("777"))) {
echo "chmodded() $filename";
}
else
{
echo "Couldn't chmod $filename\n\n";
}
The chmod works, the chown doesn't.
