Disk quotas are a function of the operating system, not PHP. They will
do what you want, but how to set them is OS dependent (and you may not
be able to do it in your code due to OS or hosting company restrictions).

What I do is when they go to the upload page, I check how much space
they have left in the directory, then set that as the maximum they can
upload.

Of course this won't work if they use ftp or similar, but it works fine
for uploading via html pages.

I don't think so. Disk quotas allow you to limit the number/size of files a
user can save in a disk partition. But PHP scripts run with the same system
user, no matter who's logged in your app.

If not, Which is the best way to achieve this?.

If I understood correctly, you don't have any control over the database or
the software that creates the files. So you need a solution that makes the
software just fail when over quota... :-?

I can't figure out how to do that. You can always remove images after being
uploaded but that'd be a big mess.

Maybe if you describe how that third party software works we can think of a
sensible solution...

Re: Limit folder (with subfolders) capacity

Well, I am giving the users the possibility to upload files by two
ways.

In the first way (photo upload) I have the control over the code (I
have written it) and is easy to control the number and size of files
uploaded.

In the second way It is more difficult because I am using a third party
software.This sotware is a wysiwyg with file upload posibility.It is
called fckeditor.I am using it in several services(messag es between
users, comments about users, blogs... ).This sofware gives you a very
nice wysiwyg interface(with upload interface included) and returns the
result as html code in a html text_area.I insert this html code in a
database.

I have "semisolved " the problem.
I have had to rewrite some code of fckeditor.

It hasn´t been very difficult but doing all this by code isn´t a very
flexible solution.

Isn´t There a way to lock a folder to a maximum size.
Of course I assume the solution (if exists) will be platform dependant;

Thanks.

Actually, you can. You can limit the size of the directory in either
Linux or Windows Server. Any attempt to store more than that in the
directory will return an error.

He needs to set limits in a per-user base. His web app will always run
under the *same* user: nobody, apache, LOCAL SYSTEM or whatever. And to
make it worse, quotas work over system users. The users that register in
your web site do not count for the OS.

I've had a very quick look at FCKeditor's code. Unluckily, it isn't object
oriented so you can't write a child class that inherits from the original
one, so you can keep in untouched. But the code itself is very simple
(after all, the project is basically a JavaScript tool) so I believe you've
chosen a good solution. Just keep track of your changes in case you even
want to upgrade. Or, if your code is good, you can even submit it to the
authors ;-)

True. But each user is assigned their own directory, and he can limit
the amount of space used by that directory.

How can you do so if you don't put each directory in a separate partition?

By using the OS tools. Both Linux and Windows 2003 Server allow you to
limit the amount of disk space used by a single directory.

See your system administrator for more information or check an OS
related newsgroup.
