in reply to CGI::Application, Template Toolkit and global parameters

You already have a couple of options that you can use, but CGI::Application::Plugin::TT gives you some extra possibilities as well. You can create a 'tt_pre_process' method in your CGI::Application module, which will be called automatically everytime you call $self->tt_process. This is useful for adding extra global variables that you want to appear in every template you parse in your application.

sub tt_pre_process { my ($self, $file, $vars) = @_; $vars->{user} = $ENV{REMOTE_USER}; $vars->{menu} = [ { text => 'Foo', link => 'foo.html', }, { text => 'Bar', link => 'Bar.html', }, ]; return; }

Alternatively, you can setup a tt_pre_process method as a callback (requires CGI::Application 4.0 or greater).

__PACKAGE__->add_callback('tt_pre_process', sub { my ($self, $file, $vars) = @_; $vars->{user} = $ENV{REMOTE_USER}; $vars->{menu} = [ { text => 'Foo', link => 'foo.html', }, { text => 'Bar', link => 'Bar.html', }, ]; return; });
