Hello!
I am using CGI.pm's hook call back and I need to use a variable defined in my (the calling) package. It's getting lost and I am not sure how to define it (without declaring it before use strict, or is that the only way??).
So, this is just the relevant code below. $test gets printed in go() but lost during the hook() callback (I understand why, just not sure what the proper way of getting around this is).
use strict;
use CGI;
our $test = "Big test";
go();
sub go {
my $q = CGI->new(\&hook);
print $test;
}
sub hook {
my ($filename, $buffer, $bytes_read, $data) = @_;
print $test;
}
