in reply to using die in CGI context / 500 errors

Chances are that the server's cgi uid does not have write permission for $dir. You can try 'tail logfile' to see the most recent errors.

    Thanks guys, the error is that the directory of filename does not exist - this is in reponse to the die statement.
    Im guessing now that die isnt dandled by browsers and thats why I got the 500 error, Anyway....
    This is my code - 
    #!/usr/local/bin/perl
use strict;
use CGI;

my $query = new CGI;

my $dir = $query->param('dir');
my $file = $query->param('file');

$file =~m/^.*(\\|\/)(.*)/;
my $name = $2;
open(LOCAL,">$dir/$name");# or die "Die: $!";

while(<$file>)
{
  print LOCAL $_;
}

print $query->header();
print $query->start_html("File Upload");

# DEBUG TO SCREEN

print "File and Dir: "$file;
print "File: ",$name;

print $query->end_html;

      If the script is on a *NIX box (which given the #! line I can see it is) and you want to access local files you will need to set up some networking calls to access them. A better (and safer answer) would be to upload your files to a folder on your server and access them from there.

        I see, so under what circumstances would the code I have written above work - I presumed it would let a client upload files to a server, but I also felt it looked much too easy - this is my first time doing any file uploading!. I wrote this code because I want to allow people to upload files to my server - these files will eventually be organised using MySql. WHat modifications will I need to make - security is a big issue too - is it possible to give someone enough access in order for them to upload a file without compromising server security - im sure it is. Anyway Thanks, Barry.
        This is the html I'm using to call the script - 
        <HTML><BODY>
<FORM ENCTYPE="multipart/form-data" ACTION="http://baz.perlmonk.org/co
+okie.cgi" METHOD="POST">
Please choose directory to upload to:<br>
<SELECT NAME="dir">
<OPTION VALUE="images">images</OPTION>
<OPTION VALUE="sounds">sounds</OPTION>
</SELECT>
<p>
Please select a file to upload: <BR> 
<INPUT TYPE="FILE" NAME="file">
<p>
<INPUT TYPE="submit">
</FORM>
</HTML></BODY>

        Quite off topic, but #! is not indicative of *nix. It's a nicety on a *nix box, but will not interfere with execution on other operating systems. (If it's not present in a *nix environment, the script can still be executed with perl script.pl.)

        If things get any worse, I'll have to ask you to stop helping me.
