Hi, I am wondering if there is a mod to allow only certain file extension types to be uploaded using fileman?

Hi Malteser:

So if you only want to allow certain file extensions or diallow (if you
want to disallow by default) then change the following subroutine:

1 sub is_valid_file {
2 # -----------------------------------------------------
3 # Checks to see if a file is valid (proper form).
4 #
5 my ($file, $okfile) = "";
6 $file = shift;
7
8 ($file =~ m,^([A-Za-z0-9\-_.]*)$,) ?
9 ($okfile = $1) :
10 (return ($file, "Illegal Characters in Filename. Please use
letters, numbers, -, _ and . only."));

11 ($file =~ m,\.\.,) and return ($file, "No double .. allowed in
file names.");
12 ($file =~ m,^\.,) and return ($file, "no leading '.' in file
names.");
13 (length($file) > 20) and return ($file, "File name is too long.
Please keep it to under 20 characters.");

14 return ($okfile, "");
15}

assuming you do not want txt file to be uploaded then
insert this line at line 11:

($file =~ m,\.txt$,i) and return ($file, "No txt file allowed");
and so on for each file extension.

However, if you don't want to allow any file extensions by default and
only allow certain files then insert at line 11: in this case only allow
txt file and disallow any other files by default

($file =~ m,\.txt$,i) or return ($file, "No txt file allowed");

you can cascade this like this:

($file =~ m,\.txt$,i) or ($file =~ m,\.jpg$,i) or return ($file,
"File not allowed");

The other thing about limiting the filesize to be uploaded:

%config = (
root_dir => "c:/WebSite/htdocs",
logfile => "c:/WebSite/htdocs/fileman/fileman.log",
password_dir => "/gossamer/www/scripts/fileman/pass",
root_url => "http://localhost",
script_url => "http://localhost/fileman/fileman.cgi",
icondir_url => 'http://localhost/fileman/icons',
use_flock => 1,
allowed_space => 10000000000,
max_upload => 75,
show_size => 1,
show_date => 1,
show_perm => 1,
show_icon => 1,
show_pass => 1,
version => '1.0'
);


change max_upload to the appropriate size.


Hope that helps

Hi Sun, thanks so much for the help. However, there is still a slight problem:

There's no problem with inserting the following as an exclusion criterion for file extension:

($file =~ m,\.txt$,i) and return ($file, "No txt file allowed");

However, I get an error message whenever loading fileman.cgi (ie. on first run I alread get the error message before I can even access the file directory) if I use the "or" argument for the same line as an inclusion criterion for file extensions (which is what I want to do):

($file =~ m,\.txt$,i) or return ($file, "No txt file allowed");

sincerely,

Malteser

Hi Malteser:

Can you please tell me what the URL for the site is? I need to take a look at the error messages myself.
