<DIV class=Section1>
<P class=MsoNormal>Folks,</P>
<P class=MsoNormal> </P>
<P class=MsoNormal> It’s been a long time since I’ve bugged y’all with a stupid question, but I’ve got a new one so I’m hoping someone can help me out.</P>
<P class=MsoNormal> </P>
<P class=MsoNormal> The problem is with exporting variables, and having them available to both a script that uses the module exporting the variable, and the module it’s self. I have two modules, one on a machine at work and one on a machine at home. Both are doing something that looks super similar to me.</P>
<P class=MsoNormal> </P>
<P class=MsoNormal> At work I have: </P>
<P class=MsoNormal> </P>
<P class=MsoNormal>package Neo::Web;</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>use ...</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>use CGI qw/:standard/;</P>
<P class=MsoNormal>use CGI::Cookie;</P>
<P class=MsoNormal>use Apache::DBI;</P>
<P class=MsoNormal>use Apache::Session::Postgres;</P>
<P class=MsoNormal>use Data::Dumper;</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>BEGIN </P>
<P class=MsoNormal>{</P>
<P class=MsoNormal> use Exporter ();</P>
<P class=MsoNormal> @ISA = qw(Exporter);</P>
<P class=MsoNormal> @EXPORT = qw(%Session $SessionID </P>
<P class=MsoNormal> &TieSession &UntieSession ... );</P>
<P class=MsoNormal> </P>
<P class=MsoNormal> ConnectDB(DBName=>'Sessions');</P>
<P class=MsoNormal>}</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>sub TieSession</P>
<P class=MsoNormal>{</P>
<P class=MsoNormal> tie %Session, 'Apache::Session::Postgres', $SessionID, {Handle=>$Neo::DB::Sessions, Commit=>0};</P>
<P class=MsoNormal> $SessionID = $Session{_session_id};</P>
<P class=MsoNormal>}</P>
<P class=MsoNormal> </P>
<P class=MsoNormal> The scripts using this package can get at %Session, and this module can get at %Session. They are the same variable and have the same contents.</P>
<P class=MsoNormal> </P>
<P class=MsoNormal> At home I have:</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>package Darley::Supers;</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>use ... ;</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>use Data::Dumper;</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>BEGIN </P>
<P class=MsoNormal>{</P>
<P class=MsoNormal> my (%CurrentUser);</P>
<P class=MsoNormal> </P>
<P class=MsoNormal> use Exporter ();</P>
<P class=MsoNormal> @ISA = qw(Exporter);</P>
<P class=MsoNormal> @EXPORT = qw(%CurrentUser</P>
<P class=MsoNormal> &Power &Challenge &GetUser &GetOrg &GetCity);</P>
<P class=MsoNormal>}</P>
<P class=MsoNormal> </P>
<P class=MsoNormal> </P>
<P class=MsoNormal>sub SetCurrentOrgSetting</P>
<P class=MsoNormal>{</P>
<P class=MsoNormal> my (%Args) = @_;</P>
<P class=MsoNormal> # Args: Setting = Setting to store</P>
<P class=MsoNormal> # Value = Value to store</P>
<P class=MsoNormal> </P>
<P class=MsoNormal> StoreOrgSetting(OrgID=>$CurrentUser{Org}{org_id}, Setting=>$Args{Setting}, Value=>$Args{Value});</P>
<P class=MsoNormal> $CurrentUser{Org}{Settings}{$Args{Setting}} = $Args{Value};</P>
<P class=MsoNormal> </P>
<P class=MsoNormal> return 1;</P>
<P class=MsoNormal>}</P>
<P class=MsoNormal> </P>
<P class=MsoNormal> And the script using this module can get at %CurrentUser, but when this package uses it, it’s empty. I can’t figure out why the exported hash is the same in the first example, but has two different values in the second.</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>Thanks for any help,</P>
<P class=MsoNormal>Peter</P>
<P class=MsoNormal> </P>
