OK, so here's for the people who think there's a problem with the regex (there isn't): this is a version which checks if the thing matches. If it doesn't, it gets a silly value...
After the assignment of the $2 to $localfilename, I print out the value of $localfilename, and yet it prints out the errormessage with an empty string for $localfilename...
#!/usr/bin/perl -w
use strict;
use CGI;
$|=1; # Don't buffer the output
my $buffer;
#print out the correct content-type
print "Content-type: text/html\n\n";
# start with nice html-tags
print "<html><body>";
# new CGI object
my $req = CGI->new;
#retrieve the value of the selected filename
my $filename = $req->param("filename");
# get only the filename (not the entire path) and if it doesn't match,
+ give $localfilename a silly value
my $localfilename = $filename =~ m/(.*?$CGI::SL)*(.*)(?=$)/ ? $2 : "AS
+illyValue";
# print out $localfilename to see if it has the correct value
print $localfilename;
# open $localfilename for output (and here it fails, with the $localfi
+lename as an empty string)
open(FILE, ">$localfilename") || print "Could not open $localfilename
+for output: $!<br>\n";
# it doesn't even get here...so ignore please...
while (my $bytesread = read($filename,$buffer,1024))
{
print FILE $buffer;
}
close(FILE);
print "File saved as $localfilename (original filename=$filename)<br>"
+;
print "</body></html>";
