Hello again! I built a page for my teacher that loads the contents of a file into a textarea in a form on a web page so he can edit some links from any browser. If the text file is empty, the script that displays the links jumps to a subroutine that says, "no links at this time"
This is only happening when I delete the contents of the file on the server. If I do it by clearing the contents of the textarea through a brower and pass them to the script, there is always 1 blank character.
I am still new to all of this, but am reading a book right now and trying things like chop, chomp, truncate.. ?
Am I close? Or have I gone completely mad?!
Here is the code that writes what was in the textarea to file:
#!/usr/bin/perl
use CGI::Carp qw(fatalsToBrowser);
use strict;
use CGI ':standard';
my $list;
my @changes = param('tellmessage');
open(FILE, ">eetnlinks.txt") || die "Can't open file!";
flock(FILE, 2) || die "Can't lock file!";
#truncate(FILE,0);
foreach $list (@changes) {
chomp ($list);
print FILE "$list\n";
}
close(FILE);
