Are you watching from the Arabic man's tutorials? (Ali Hamdi)
I experienced the same thing and I made my else statement of the display class this way:
else
{
$num = mysql_num_rows($sql);
while ($num > 0)
{
$data = mysql_fetch_array($sql);
$num--;
}
}
return $data;
}
}
?>
It didn't solve the problem, but it brought back the form at least. So I continued watching the rest of the tutorials and following him so that later I address that part. I have written him and awaiting for his response. as soon as he does, I'll get back to you with the solution.
