Thank you, all who replied. This helps me understand. I might give a
try to the workarounds some suggested.
Great newsgroup.

Not at all. The user-agent is built to ignore files that exceed the
MAX_FILE_SIZE value.

Yes, I know and knew that. That's why the upload ultimately fails
(which is okay).
My point is that when a file's size exceeds the MAX_FILE_SIZE value,
I want the browser to (a) detect that it's too large BEFORE
attempting to upload
And here is the dump of the $_FILES array (which, notably, reports
zero as the size):
[error] => 2
And also gives you an error code.

The punchline question is: What am I missing?
Now for the details.
I have a form through which a user uploads image files. In the event
the chosen file exceeds the MAX_FILE_SIZE (which I have included as
a hidden form field immediately after the form tag), I want to abort
the upload process and d

It's up to the browser whether or not it uses that setting, most don't.

This is what is says in the online php manual:
... You should add the MAX_FILE_SIZE form variable anyway as it saves users
the trouble of waiting for a big file being transferred only to find that it
was too big and the transfer actually failed.
... The MAX_FILE_SIZE hidden field must precede the
the problem with doing it on your server (you do it just to be sure though)
is that the user has to wait for the form + file to be sent to your server
before you can respond - this can be very slow

Jacob,
When you upload a file, it appends a few of its own variables. One of them
is size - assuming the file is a variable called $file:
if ($file_size > $max_size) {
echo $file_name . " was too big!";
}
Also, you could check for Mime types.
if ($file_type != "image/jpeg" || $file_type !
When I set and a
user uploads a file bigger than 50 my script prints a warning.
How can I use MAX_FILE_SIZE and avoid that warning so that I can print my
own error message to the user ?
:) Jacob
