Hi (a very big one!)

What's the use of that hidden field named "MAX_FILE_SIZE" when we make a multipart/form-data? It only accepts the
allowed file size, right? But PHP itself says that you can easily dupe it, if it's so, why should we use it at all?
I tested it and it didn't have any problem, you can easily remove that hidden field and your file upload script works wihtout any problem. I also had some real problems with that field, and I couldn't even upload a 15K file while my allowable file size was 2MB, and I couldn't figure out why it's not working. Now that I delete that field, everything is working fine!

Another question: My PHP's "post_max_size" variable shows 8MB (I'm using PHPDev), but when I attempt to upload a 4MB file, it doesn't upload it and says it exceeds your 2MB limit, I have no 2MB limit! And I removed that annoying hidden field from my form, so, I'm sure that it's nothing wrong client side, except the file size maybe! :p What can I do?!
(the maximum file that I uploaded so far was around 900KB that's really more than what I need, I'm just curious to see if I can upload my whole 80GB hard disk via a form into a host! Is that possible?)

The last question of mine! How can I suppress the warning message that is displayed when an uploaded file exceeds the
post_max_size? I used "error_reporting(0)" at the top of my script, but it doesn't work! Do you know of any way? How
can I put a custom warning?

Thank you, I know I shouldn't usually ask 3 questions in one thread, but these are all related to each other! I'm asking about the MAX_FILE_SIZE in all of them and I think I can put them all in here!
